Installation and Application Information
Chiller Nomenclature

General Description

Daikin air-cooled water chillers are complete, self-contained, automatic chiller units designed for outdoor installation. Packaged units are completely assembled, factory wired, charged, and tested. Remote evaporator units require field refrigerant piping, pressure testing, evacuation, charging with field-supplied refrigerant and field control wiring.

The electrical control center includes all equipment protection and operating controls necessary for dependable automatic operation.

Additional Manuals

This manual covers the installation, of dual circuit, AGZ-DH packaged, scroll compressor chillers using R-410A.

Operating and maintenance information is contained in the current version of operating manual OMM 1166, available at www.DaikinApplied.com.

Inspection

Check all items carefully against the bill of lading. Inspect all units for damage upon arrival. Report shipping damage and file a claim with the carrier. Check the unit nameplate before unloading, making certain it agrees with the power supply available. Daikin Applied is not responsible for physical damage after the unit leaves the factory.

Handling

Be careful to avoid rough handling of the unit. Do not push or pull the unit from anything other than the base. Block the pushing vehicle away from the unit to prevent damage to the sheet metal cabinet and end frame (see Figure 1).

To lift the unit, 2-1/2" (64mm) diameter lifting eyes are provided on the base of the unit. Arrange spreader bars and cables to prevent damage to the condenser coils or cabinet (see Figure 2).

Operating and Standby Limits

Unit PlacementAGZ units are for outdoor applications and can be mounted either on a roof or at ground level. For roof mounted applications, install the unit on a steel channel or I-beam frame to support the unit above the roof. For ground level applications, install the unit on a substantial base that will not settle. Use a one-piece concrete slab with footings extended below the frost line. Be sure the foundation is level within 0.5” (13mm) over its length and width. The foundation must be strong enough to support the weights listed in the Physical Data Tables beginning on page 36.

Service Clearance

Sides: Minimum of 4 feet (1.22 m)

Control panel end: Minimum of 4 feet

Opposite control panel:

• Minimum 4 feet on models 075 to 130;

• 12 feet on models 140-190 (allows clearance to remove the evaporator ).

Air Clearance

Daikin's advanced “W” coil design and open air-passage ends allow very close unit spacing and a small installation footprint. The AGZ-D fans are canted inward and reduce recirculation by directing discharge air to the center of the unit, reducing the tendency to flow outward and spill over into the coil inlet.

Sufficient clearance must be maintained between the unit and adjacent walls or other units to allow the required unit air flow to reach the coils. Failure to do so will result in a capacity reduction and an increase in power consumption. No obstructions are allowed above the unit at any height.

Spacing Requirements

In general, with a small performance penalty in some cases, AGZ-D units can be spaced at four feet from other units or a wall. Curves on the following pages give the minimum clearance for different types of installations and also capacity reduction and power increase if closer spacing is used.

Case 1: Wall on One Side

In this case a solid wall up to 24-feet is considered. (For walls higher than 24 ft., use the 24-foot values.) Also use these charts for an adjacent building. For perforated screening walls, use Case 4. Spacing is differentiated by unit size families.

Figure 3: Wall on One Side of Unit

Note: Maintain a minimum of 4-feet on all sides; except models 140-190, which require 12-feet opposite the control panel to remove the evaporator.

For models AGZ 075-100: use 4 feet from any height wall. For models 110-190, use Performance Adjustment curves below.

IM 1165-1 5


Case 2: Two Units, Side-by-Side

Maintain a minimum of 6-feet on all sides; except models 140-190, which require 12-feet opposite the control panel to remove the evaporator.

Figure 7: Case 2 - Two units side by side

For models AGZ 075-100: use 4 feet between units. For models 110-190, use Performance Adjustment chart in Figure 8.

Figure 8: Case 2 Adjustment Factors

Case 3: Three or More Units, Side-by-Side

Maintain a minimum of 6-feet on all sides; except models 140-190, which require 12-feet opposite the control panel to remove the evaporator. For more than three units, allow an additional 2-feet clearance between units.

Figure 9: Case 3 - 3 units side by side

Data is for the middle unit - with a unit on each side. See Case 2, page 6 for Adjustment Factors for the two outside units.

Figure 10: Case 3 Adjustment Factors

6 IM 1165-1


Case 4: Open Screening Walls

Decorative screening walls are often used to help conceal a unit either on grade or on a rooftop. Design these walls such that the combination of their open area and distance from the unit do not require performance adjustment. It is assumed that the wall height is equal to or less than the unit height when mounted on its base support. If the wall height is greater than the unit height, see Case 5, Pit Installation. The distance from the sides of the unit to the side walls must be sufficient for service, such as opening control panel doors. For uneven wall spacing, the distance from the unit to each wall can be averaged providing no distance is less than 4 feet. Values are based on walls on all four-sides.

Figure 11: Case 4 Adjustment Factor

Case 5: Pit Installation

Pit installations can cause operating problems from air recirculation and restriction, and require care that sufficient air clearance is provided, safety requirements are met and service access is provided. Pit covers must have abundant open area at least equal to the chiller footprint. A solid wall surrounding a unit is essentially a pit and this data should be used.

Steel grating is sometimes used to cover a pit to prevent accidental falls or trips into the pit. The grating material and installation design must be strong enough to prevent such accidents, yet provide abundant open area to avoid recirculation problems. Have any pit installation reviewed by the Daikin Applied sales representative prior to installation to ensure it has sufficient air-flow characteristics, and approved by the installation design engineer to avoid risk of accident.

Figure 12: Case 5 - Pit Installation



IM 1165-1 7


Chilled Water Piping

Field installed water piping to the chiller must include:

• A cleanable strainer installed at the water inlet to the evaporator to remove debris and impurities before they reach the evaporator. Install cleanable strainer within 5 feet (1500 mm) of pipe length from the evaporator inlet connection and downstream of any welded connections (no welded connections between strainer and evapora-tor). See Inlet Strainer Guidelines for more information including required perforation size.

• A water flow switch must be installed in the horizontal piping of the supply (evaporator outlet) water line to avoid evaporator freeze-up under low or no flow condi-tions. The flow switch may be ordered as a factory-installed option, a field-installed kit, or may be supplied and installed in the field. See page 11 for more informa-tion.

• Piping for units with brazed-plate evaporators must have a drain and vent connection provided in the bottom of the lower connection pipe and to the top of the upper connection pipe respectively, see Figure 16. These evap-orators do not have drain or vent connections due to their construction. Shell-and-tube evaporators have a drain located on the bottom of the evaporator. They are drained of water in the factory and shipped with evapo-rator drain plugs removed, stored in the control panel or with an open ball valve in the drain holes. Be sure to replace plugs or close the valves prior to filling the shell-and-tube evaporator with fluid.

• Purge air from the water system before unit start-up to provide adequate flow through the evaporator.

• Adequate piping support, independent from the unit, to eliminate weight and strain on the fittings and connec-tions.

• Method to read temperatures and pressures entering and leaving the evaporator for service and performance veri-fications.

It is recommended that the field installed water piping to the chiller include:

• Thermometers at the inlet and outlet connections of the evaporator.

• Water pressure gauge connection taps and gauges at the inlet and outlet connections of the evaporator for mea-suring water pressure drop.

• Shutoff valves are necessary to isolate the unit from the piping during unit servicing.

• Minimum bends and changes in elevation to minimize pressure drop.

• An expansion tank or regulating valve to maintain ade-quate water pressure

• Vibration eliminators in both the supply and return water lines to reduce transmissions to the building, required when the unit is mounted on spring isolators.

• Flush the system water piping thoroughly before making connections to the unit evaporator.

• Piping insulation, including a vapor barrier, helps pre-vent condensation and reduces heat loss.

• Regular water analysis and chemical water treatment for the evaporator loop is recommended immediately at equipment start-up.

Inlet Strainer Guidelines

An inlet water strainer kit must be installed in the chilled water piping before the evaporator inlet. A few paths are available to meet this requirement:

1 A field-installed kit shipped-loose with the unit is available for all unit sizes and consists of:

• Y-type area strainer with 304 stainless steel perforated basket, Victaulic pipe connections and strainer cap.

• Extension pipe with (2) Schrader fittings that can be used for a pressure gauge and thermal dispersion flow switch. The pipe provides sufficient clearance from the evaporator for strainer basket removal.

• ½-inch blowdown valve

• Two grooved clamps

The strainer is sized per Table 2 and with the pressure drop shown in the Strainer Pressure Drop graph. Connection sizes are given in the Dimensions and Weights section on page 21.

2 A field-supplied strainer that meets specification and installation requirements of this manual.

Table 2: Strainer Data

CAUTION

To prevent damage to the evaporator and potential chiller failure, a supply strainer is required in the inlet water piping which connects to this evaporator. This strainer must be installed prior to operation of the chilled liquid pumps.

Figure 15: Strainer Pressure Drop

Water Flow Limitations Constant Evaporator Flow

The evaporator flow rates and pressure drops shown on page page 44 are for full load design purposes. The maximum flow rate and pressure drop are based on a 6°F temperature drop. Avoid higher flow rates with resulting lower temperature drops to prevent potential control problems resulting from very small

control bands and limited start up/shut off temperature changes.

The minimum flow and pressure drop is based on a full load evaporator temperature drop of 16°F. Evaporator flow rates below the minimum values can result in laminar flow causing freeze-up problems, scaling and poor control. Flow rates above the maximum values will result in unacceptable pressure drops and can cause excessive erosion, potentially leading to failure.

Variable Evaporator Flow

Reducing evaporator flow in proportion to load can reduce system power consumption. The rate of flow change should be a maximum of 10 percent of the flow per minute. For example, if the maximum design flow is 200 gpm and it will be reduced to a flow of 140 gpm, the change in flow is 60 gpm. Ten percent of 200 gpm equals 20 gpm change per minute, or a minimum of three minutes to go from maximum to minimum. Do not reduce flow lower than the minimum flows listed in the evaporator pressure drop section, page 44. The water flow through the evaporator must remain between the minimum and maximum values listed on page 44. If flow drops below the minimum allowable, large reductions in heat transfer can occur. If the flow exceeds the maximum rate, excessive pressure drop and tube erosion can occur.

System Water Volume Considerations

All chilled water systems need adequate time to recognize a load change, respond to that load change and stabilize, without undesirable short cycling of the compressors or loss of control. In air conditioning systems, the potential for short cycling usually exists when the building load falls below the minimum chiller plant capacity or on close-coupled systems with very small water volumes. Some of the things the designer should consider when looking at water volume are the minimum cooling load, the minimum chiller plant capacity during the low load period and the desired cycle time for the compressors. Assuming that there are no sudden load changes and that the chiller plant has reasonable turndown, a rule of thumb of "gallons of water volume equal to two to three times the chilled water gpm flow rate" is often used. A storage tank may have to be added to the system.

BAS should enable chiller only when there is a cooling demand.

Evaporator Freeze Protection

Evaporator freeze-up can be a concern in the application of air-cooled water chillers. To protect against freeze-up, insulation and electric heaters are furnished with the unit. Models 140 through 190 have immersion heaters with a thermostat; models 075 through 130 have an external plate heater and thermostat. They protect the evaporator down to -20°F (-29°C) ambient air temperature; however, see Chilled Water Pump section for more information. Although the evaporator is equipped with freeze protection, it does not protect water piping external to the unit or the evaporator itself if there is a power failure or heater cable burnout, or if the chiller is unable to control the chilled water pumps. Use one of the following recommendations for additional protection:

1 If the unit will not be operated during the winter, drain evaporator and chilled water piping and flush with glycol. Drain and vent connections are provided on the evaporator to ease draining.

2 Add a glycol solution to the chilled water system to provide freeze protection. Freeze point should be approximately 10ºF below minimum design ambient temperature.

3 The addition of thermostatically controlled heat and insulation to exposed piping.

The evaporator heater cable is factory wired to the 115 volt circuit in the control box. This power should be supplied from a separate source, but it can be supplied from the control circuit. Operation of the heaters is automatic through the ambient sensing thermostat that energizes the evaporator heaters for protection against freeze-up. Unless the evaporator is drained in the winter or contains an adequate concentration

of anti-freeze, the disconnect switch to the evaporator heater must not be open.

Chilled Water Pump

It is important that the chilled water pumps be wired to, and controlled by, the chiller's microprocessor. When equipped with optional dual pump output, the chiller controller has the capability to selectively send the signal to a pump relay (by others) to start pump A or B or automatically alternate pump selection and also has standby operation capability. The controller will energize the pump whenever at least one circuit on the chiller is enabled to run, whether there is a call for cooling or not. This helps ensure proper unit start-up sequence. The pump will also be turned on when the water temperature goes below the Freeze Setpoint for longer than a specified time to help prevent evaporator freeze-up. Connection points are shown in the Field Wiring Diagram on page 46.

Failure to allow pump control by the chiller may cause the following problems:

1 If any device other than the chiller attempts to start the chiller without first starting the pump, the chiller will lock out on the No Flow alarm and require manual reset.

2 If the chiller evaporator water temperature drops below the “Freeze setpoint” the chiller will attempt to start the water pumps to avoid evaporator freeze. If the chiller does not have the ability to start the pumps, the chiller will alarm due to lack of water flow.

3 If the chiller does not have the ability to control the pumps and the water system is not to be drained in temperatures below freezing, the chiller may be subject to catastrophic evaporator failure due to freezing. The freeze rating of the evaporator is based on the immersion heater and pump operation. The immersion heater itself may not be able to properly protect the evaporator from freezing without circulation of water.

Low Ambient Operation

Compressor staging is adaptively determined by system load, ambient air temperature, and other inputs to the MicroTech III control. A low ambient option with fan VFD allows operation down to -10° F (-23° C). The minimum ambient temperature is based on still conditions where the wind is not greater than five mph. Greater wind velocities will result in reduced discharge pressure, increasing the minimum operating ambient temperature.

CAUTION

Adding glycol or draining the system is the recommended method of freeze protection. If the chiller does not have the ability to control the pumps and the water system is not drained in temperatures below freezing, catastrophic evaporator failure may occur.

10 IM 1165-1


High Ambient Operation

AGZ-D units for high ambient operation (105ºF to 125ºF, 40.1ºC to 51.7ºC) require the addition of the optional high ambient package that includes a small fan with a filter in the air intake to cool the control panel.

All units with the optional VFD low ambient fan control automatically include the high ambient option.

Flow Switch

All chillers require a chilled water flow switch to check that there is adequate water flow through the evaporator and to shut the unit down if there isn't. There are two options for meeting this requirement.

1 A factory-mounted thermal dispersion flow switch.

2 A "paddle" type flow switch is available from Daikin Applied for field mounting and wiring. Wire from switch terminals Y and R to the unit control panel terminals shown on the field wiring diagrams, beginning on page 46. Mount the flow switch in the leaving water line to shut down the unit when water flow is interrupted. A flow switch is an equipment protection control and should never be used to cycle a unit.

Installation should be per manufacturer's instructions included with the switch . Flow switches should be calibrated to shut off the unit when operated below the minimum listed flow rate for the unit as listed on page 44.

There is also a set of normally closed contacts on the switch that can be used for an indicator light or an alarm to indicate when a "no flow" condition exists. Freeze protect any flow switch that is installed outdoors. Differential pressure switches are not recommended for outdoor installation. They can freeze and not indicate a no-flow conditions.

Grooved Coupling/Flow Switch Warning

On units with shell-and-tube vessels and with factory-mounted flow switches and where flange connections (grooved-to-flange adaptors or weld-on flanges) are to be used, relocating the flow switch is required to allow for possible future replacement. The flange will interfere with unscrewing the switch. The following procedure is recommended before installing a flange to avoid interference:

1.Remove the flow switch and plug the switch opening in the nozzle.

2.Install the grooved-to-flange adaptor or weld on flange.

3.Relocate the flow switch in the water piping outside the flange, close enough to it that the wire leads will reach and the switch can still be unscrewed.

Glycol Solutions

The use of a glycol/water mixture in the evaporator to prevent freezing will reduce system capacity and efficiency, as well as increase pressure drop. The system capacity, required glycol solution flow rate, and pressure drop with glycol may be calculated using the following formulas and tables.

1 Capacity - Multiply the capacity based on water by the Capacity correction factor from Table 3 to Table 6.

2 Flow - Multiply the water evaporator flow by the Flow correction factor from Table 3 to Table 6 to determine the increased evaporator flow due to glycol. If the flow is unknown, it can be calculated from the following equation:

3 Pressure drop - Multiply the water pressure drop from Table 27 by Pressure Drop correction factor from Table 3 to Table 6. High concentrations of propylene glycol at low temperatures may cause unacceptably high pressure drops.

4 Power - Multiply the water system power by Power correction factor from Table 3 to Table 6.

Test coolant with a clean, accurate glycol solution hydrometer (similar to that found in service stations) or refractometer to determine the freezing point. Obtain percent glycol from the freezing point table below. It is recommended that a minimum of 25% solution by weight be used for protection against corrosion or that additional compatible inhibitors be added. Concentrations above 35% do not provide any additional burst protection and should be carefully considered before using.

CAUTION

Do not use an automotive-grade antifreeze. Industrial grade glycols must be used. Automotive antifreeze contains inhibitors which will cause plating on the copper tubes within the chiller evaporator. The type and handling of glycol used must be consistent with local codes.

POE Lubricants

POE type oil is used for compressor lubrication. This type of oil is extremely hydroscopic which means it will quickly absorb moisture if exposed to air and may form acids that can be harmful to the chiller. Avoid prolonged exposure of POE oil to the atmosphere to prevent this problem. For more details on acceptable oil types, contact your Daikin Applied service representative.

It is important that only the manufacturer’s recommended oils be used. Acceptable POE oil types are:

• CPI/Lubrizol Emkarate RL32-3 MAF

• Copeland Ultra 32-3 MAF

• Parker Emkarate RL32-3MAF

• Virginia LE323MAF

• Nu Calgon 4314-66

Remote Evaporators
Remote Evaporators
Piping and Application

AGZ-D units have two circuits, each with either two or three compressors. These circuits must be kept separated throughout the entire refrigerant piping system. Pipe all lines (suction, liquid and hot gas bypass, if used) of each evaporator circuit to a circuit on the outdoor unit. Be careful not to cross-pipe lines.

Evaporator circuit #1 must be piped to the circuit #1 condensing unit . Evaporator circuit #2 must be piped to the circuit #2 condensing unit.

Figure 18: Location of Connections

Piping Recommendations

IMPORTANT: Refrigerant piping design must be provided by a qualified Architect or Systems HVAC Design Engineer familiar with piping design, as well as local codes and regulations. The manufacturer recommendations provided here are to be used as a general guide, but do not replace system design by a qualified professional. All field piping, wiring, and procedures must be performed in accordance with ASHRAE, EPA, local codes, and industry standards.

Proper refrigerant piping can make the difference between a reliable system and an inefficient, problematic system. See the recommended field pipe sizes shown in Table 8 and Table 10. For additional information about refrigerant piping techniques and sizing, see the Daikin Refrigerant Piping Design Guide, AG 31-011, which can be found on www.DaikinApplied.com.

The primary concerns related to piping are refrigerant pressure drop; a solid liquid feed to the expansion valves, continuous oil return and properly sized refrigerant specialties.

AGZ-D Unit Performance is negatively affected by Suction Line Pressure Drop Losses. Distance between the AGZ-D unit and the Remote Evaporator should be kept as short as possible to minimize the performance derate.

Refrigerant piping is permitted to be installed below ground provided the following conditions are met:

• Piping or pipe insulation is NOT in contact with the ground

• Piping is installed in an open or enclosed chase that allows for inspection and leak testing

• Piping is sized and installed per ASHRAE guidelines

For Installations where the evaporator is installed either above or below the unit - the following recommendations apply:

Evaporator installed below outdoor unit:

• 30 ft. Maximum Vertical Distance

• Only single riser suction tubing is to be used - Double riser installations are not permitted

• A suction line trap must be installed at the bottom of the riser and a second trap at 20 ft. height

Evaporator installed above the AGZ-D Outdoor unit:

• 30 ft. Vertical Distance is the recommended maximum to prevent loss of liquid subcooling

Installation Guidelines

Insulate the suction line to reduce excessive superheat build-up. Insulate the liquid line, where located in areas above ambient temperature, to prevent loss of subcooling and consequent liquid flashing.

The installer must leak test the remote piping with nitrogen at 150 psig maximum pressure, then properly evacuate the piping systemto 500 microns or below and provide the operating charge of R-410A. A holding charge of nitrogen/helium is

CAUTION

Refrigerant circuits must be kept isolated from eather throughout the entire system. For braze plateevaporators, note

Remote Evaporators

provided for the outdoor section. The brazed-plate evaporators on Models 075 to 130 have no charge and are not sealed. The shell-and-tube evaporators on Models 140 to 190 have a nitrogen holding charge. Holding charges must be removed prior to the R-410a charging procedure.

The use of double risers for vertical gas risers is not allowed. Size the vertical riser per Table 8. Follow ASHRAE procedures.

Slope the refrigerant lines 1" per 10 feet of horizontal run in the direction of refrigerant flow to assist oil return.

Avoid using hot gas bypass (or provide condenser fan VFDs) for applications when operation in ambient temperature below 40ºF is expected. This is necessary to maintain adequate condensing pressures and liquid refrigerant at the expansion valve when condenser capacities are at their maximum.

Interconnecting refrigerant piping and total system refrigerant charge are field supplied and installed. The outdoor unit and remote evaporator are shipped with a nitrogen holding charge that must be removed and replaced with R 410A.

Pressure drops in the refrigerant lines should be maintained at the equivalent feet calculation shown in Table 8 and should not exceed 3°F and line lengths should be made as short as possible. Follow ASHRAE recommendations. Exceeding these recommendations will decrease performance and could impact reliability.

A small trap must be provided at the base of each major vertical gas riser to assist in the collection of oil. If vertical risers exceed more than 20 feet, install a small trap at the midpoint and at a maximum of 20 foot intervals.

Use caution in sizing the liquid line in applications where the evaporator is above the outdoor section. The weight of the liquid refrigerant in the vertical column will decrease the pressure at the top of the riser (0.43 psi per foot of vertical rise) allowing some of the refrigerant to flash to a gas. Adequate refrigerant subcooling is needed at the expansion valve for proper operation.

Care should be taken while designing piping system to avoid the draining of condensed refrigerant to the lower component when normal shutdown procedures do not occur (such as a power failure).

Location of Liquid Line Filter Drier, Solenoid Valve and Expansion Valve

These components must be installed adjacent to the Remote evaporator. The expansion valves must be installed within 12 inches of the Evaporator Inlet Connection and the outlet piping of the Expansion valve must go directly into the Evaporator with no bends in between.

The Liquid line Solenoid valves must be installed within 3 ft. of the evaporator. The Liquid line Solenoid Valve must be connected to the AGZ cable using a junction box to extend the wiring to the length required to reach the solenoid.

The Liquid line Filter Drier must be installed at the Remote Evaporator - upstream of the Liquid Solenoid Valve and Expansion Valve

How to determine performance derate: Using the model size and the equivalent feet of piping between the unit and the evaporator, find the Pressure Drop in °F from Table 8. Cross-reference the Pressure Drop in °F to Table 9 to find the capacity, power, and EER derate factor.

Wiring for AGZ-Remote EvaporatorsRefrigerant Specialties Kit

Remote Evaporator units include a Refrigerant Specialties Kit which supplies the following field-installed components:

• Charging valves

• Expansion valves

• Models 075-130 use Thermal Expansion Valves (TXV), EXV is option

• Models 140-190 use Electronic Expansion Valves (EXV) and includes M12 cable

• Liquid line solenoid valves and cable

• Liquid line filter driers with filter drier core, clamp, and felt gasket

• Liquid line sight glasses (and saddle adapter for AGZ140-190D)

• Ball valves

• Suction temperature sensor tubes

• Schrader fittings and Schrader core for suction transducers

Sensor Wiring

The Remote Evaporator AGZ-D Units come with long sensor wires for the remote evap installation. These wires allow the evaporator to be installed up to 90 ft. from the AGZ-D unit without splicing these wires. The sensor wires to the evaporator include the following :

• Evaporator Water Inlet and Outlet Temperature Sensor

• Suction Line Temperature Sensors for Piping at the Evaporator for both Circuit #1 and #2

• Suction Transducer Wiring for Installation on Evaporator Suction Piping for both Circuit #1 and #2

For AGZ140-190D units with Electric Expansion Valves, the wiring to the evaporator must be spliced using #14 wire gauge shielded wire.

The factory supplied cable with #18 ga wire is suitable for 30 ft. maximum length. For installations where the evaporator will be located more than 30 ft from the outdoor unit, the sensors must be relocated to the Suction Line piping at the Evaporator for proper unit operation. If the evaporator is located within 30 linear feet of piping from the outdoor unit, the two suction temperature sensors can be left on the outdoor

Remote Evaporators

unit factory suction line as shipped only if TXVs are used. EXVs require sensors be located at the evaporator.

There are two evaporator water temperature sensors with 90 feet of cable coiled in the unit behind the control panel for extension to the evaporator and insertion in fitting located on the inlet and outlet nozzle on AGZ-D models 140 to 190. For models AGZ 075 to 130 with brazed-plate evaporators, the sensors are inserted into back of heat exchanger, opposite the water connections, at the designated inlet and outlet water temperature sensor locations.

There is one suction line refrigerant temperature sensor per circuit installed on suction line with 90 feet of cable coiled behind the unit control panel, intended for extension to the evaporator. Place the sensor in a brazed well (provided in kit, installed in the field) on the suction line in a straight-flat area, close to the suction line pressure transducer. Install with heat conductive compound and insulate well. If installed on a horizontal pipe run, locate between the 2-4 o'clock positions, or, on a TXV, locate the bulb and equalizer line on suction line at the 3 or 9 o’clock position.

There is one suction line pressure transducer per circuit with 90 feet of cable coiled, installed on the suction line behind the unit control panel for extension to the evaporator. Mount the transducer in the suction line, 1-2 feet from the evaporator head, on the top or side of the pipe. Connection is ¼-inch flare with a flare Schrader.

One solenoid valve per circuit must be wired to the unit control panel. They come equipped with an 8-foot cable that must be added to. See the wiring diagram on page 65 for connection points at unit.

Expansion Valve Wiring

AGZ-D models 075-130 use Thermal Expansion Valves (TXV standard, EXV optional). These valves must be located within 12 inches of the evaporator liquid line connections and the expansion valve bulbs. The 1/4” equalizer lines must be attached to the suction pipes near the evaporator outlet.

AGZ-D models 140-190 use Electronic Expansion Valves (EXV). The EXV has a 1 ft. cable attached with an M12 Threaded Connector. A 15 ft. cable is supplied with the kit to attach to the 1 ft cable at the valve.

The field must supply #14 ga. shielded wires to extend this cable to run back and connect to the Expansion Valve control module located inside the AGZ-D control box. When splicing is required the connections must be soldered together and individually shrink wrapped to be made water resistant. The expansion valve wiring cannot run in conduit with other wiring that is over 24 Volts AC. Shielding must cover the wiring from the unit to the EXV, including the splice connection.

The electronic expansion valve has a 40-foot long cable attached and can be used, when the outdoor unit is less than 40 feet away. Beyond that, a junction box must be located within

40-feet of the evaporator, and up to 60 additional feet of 14GA shielded wire connected from the cable to the unit, allowing up to a total distance of 100 feet.

Figure 19: EXV Field Wiring

Liquid Line Solenoid Valve Wiring

The Liquid Line Solenoid valves are supplied as part of the Specialties Kit. These valves must be located within 3 feet of the evaporator. Included with the Liquid Line Solenoids are wiring cables which are 10 ft. long. These cables must be connected to the termfinal block inside the AGZ-D control box via a field-supplied junction box and #14 ga. wiring. This 24volt wiring should be run in conduit, or at a minimum, two-wire cable with a protective covering must be used. See Field Wiring Diagram included in unit, or Typical Field Wiring Diagram on page 46 and page 47 for wiring schematic.

Pumpdown

The pumpdown capacity of AGZ units is given in the Physical Data Tables starting on page 36. Care should be exercised to include all equipment and lines when calculating the system charge relative to the unit's pumpdown (storage) capacity. The AGZ-D remote evaporators have an insignificant operating charge. It is mandatory that the liquid line solenoid valve be located close to the evaporator so that pump down does not have to remove and store a large quantity of liquid refrigerant from the liquid line.

Electrical Notes
Electrical Notes
Electrical Data Notes1 Power wiring connections to the chiller must be done

with copper wiring. Wire should be sized per NEC and/or local codes. Wire sizing and wire count must fit in the power connection lug sizing shown in the Electrical Data tables starting on page 50.

2 Compressor RLA values are for calculation purposes only. The RLA values are not the same as operating amperage at design conditions. Actual operating amperage will vary from the listed RLA values.

3 Unit wire size ampacity (MCA) is equal to 125% of the largest compressor-motor RLA plus 100% of RLA of all other loads in the circuit.

4 Recommended Fuse Sizes are selected at approximately 175% of the largest compressor RLA, plus 100% of all other loads in the circuit.

5 Maximum Fuse or breaker size is equal to 225% of the largest compressor RLA, plus 100% of all other loads.

6 The control transformer is furnished and no separate 115V power is required. For both single- and multi-point power connections, the control transformer is in circuit #1 with control power wired from there to circuit #2. In multi-point power, disconnecting power to circuit #1 disconnects control power to the unit.

7 Wire sizing amps is 10 amps if a separate 115V power supply is used for the control circuit.

8 Single-point power supply requires a single disconnect to supply electrical power to the unit. This power supply must either be fused or use a circuit breaker.

9 All field wire lug range values given in the Electrical Data tables starting on page 50 apply to 75°C rated wire per NEC.

10 Must be electrically grounded according to national and local electrical codes.

Voltage Limitations:1 Within 10 percent of nameplate rating.2 Voltage unbalance not to exceed 2% with a resultant

current unbalance of 6 to 10 times the voltage unbalance per NEMA MG-1, 2009 Standard Rev. 1-2010.

Table 28: HSSCR Panel Rating

Table 29: Standard Panel Rating

Circuit Breakers

Factory installed compressor circuit breakers are standard on units with single point power supply only; they provide compressor short circuit protection and make servicing easier.

Electrical Control Center

Operating and equipment protection controls and motor starting components are separately housed in a centrally located, weather resistant control panel with hinged and tool-locked doors. In addition to the MicroTech® III controller described in the next sections, the following components are housed in the panel:

• Power terminal blocks, multi-point connection standard• Control, input, and output terminal block• Control transformer• Optional disconnect switch (through-the-door handle)• Compressor motor inherent thermal and overload protec-

tion is standard • Optional phase voltage monitor with under/over voltage

and phase reversal protection• Fan contactors with short circuit protective devices.• Optional ground fault protection• FanTrol fan staging head pressure control system• Power connections are per the following table

Power ConnectionsTable 30: Power Connection Availability

Definitions:

1 Power Block: An electrical device to directly accept field wiring without any disconnecting means.

2 Disconnect Switch: A molded case switch that accepts field wiring and disconnects main power to the entire unit or each main power supply if the multi-point power supply option is selected. This option does not provide overcurrent protection.

3 Compressor Circuit Breakers: A manually reset circuit breaker for each compressor, providing compressor only short circuit protection and located ahead of the contactor.

4 Control Panel High Short Circuit Current Rating: (Previously known as "withstand rating"). The entire control panel is designed for short circuit current rating as shown above. In the event of a short circuit, the damage is contained within the control panel enclosure.

Startup and Shutdown Procedures and Component Operation
Pre-Startup

Inspect the chiller to ensure no components became loose or damaged during shipping or installation including leak test and wiring check.

Pre-Startup Water Piping

1 Ensure evaporator inlet water strainer has been installed per requirements. Flush system and clean all water strainers before placing the chiller into service.

2 Check the pump operation and vent all air from the system.

3 Circulate evaporator water, checking for proper system pressure and evaporator pressure drop. Compare the pressure drop to the evaporator water pressure drop curve.

4 Check water treatment and proper glycol percent.

Pre-Startup Refrigerant Piping

1 Check all exposed brazed joints for evidence of leaks. Joints may have been damaged during shipping or when the unit was installed.

2 Check that all refrigerant valves are either opened or closed as required for proper operation of the chiller.

3 A thorough leak test must be done using a validated electronic leak detector. Check all valve stem packing for leaks. Replace all refrigerant valve caps and tighten.

4 Check all refrigerant lines to insure that they will not vibrate against each other or against other chiller components and are properly supported.

5 Check all connections and all refrigerant threaded connectors.

6 Look for any signs of refrigerant leaks around the condenser coils and for damage during shipping or installation.

7 Connect refrigerant service gauges to each refrigerant circuit before starting unit.

Pre-Startup Electrical

1 Open all electrical disconnects and check all power wiring connections. Start at the power block and check all connections through all components to and including the compressor terminals. These should be checked again after 3 months of operation and at least yearly thereafter.

2 Check all control wiring by pulling on the wire at the spade connections and tighten all screw connections. Check plug-in relays for proper seating and to insure retaining clips are installed.

3 Put System Switch (S1) to the Emergency Stop position.

4 Put both circuit #1 & #2 switches to the Pumpdown and Stop position.

5 Apply power to the unit. The panel Alarm Light will stay on until S1 is closed. Ignore the Alarm Light for the check out period. If you have the optional Alarm Bell, you may wish to disconnect it.

6 Check at the power block or disconnect for the proper voltage and proper voltage between phases. Check power for proper phasing using a phase sequence meter before starting unit.

7 Check for 120 Vac at the optional control transformer and at TB-2 terminal #1 and the neutral block (NB).

8 Check between TB-2 terminal #7 and NB for 120 Vac supply for transformer #2.

9 Check between TB-2 terminal #2 and NB for 120 Vac control voltage. This supplies the compressor crank case heaters.

10 Check between TB-3 terminal #17 and #27 for 24 Vac control voltage.

Startup

Refer to the MicroTech III Controller information in the operating manual OMM 1087 to become familiar with unit operation before starting the chiller.

There should be adequate building load (at least 50 percent of the unit full load capacity) to properly check the operation of the chiller refrigerant circuits.

Be prepared to record all operating parameters required by the "Compressorized Equipment Warranty Form". Return this information within 10 working days to Daikin Applied as instructed on the form to obtain full warranty benefits.

Startup Steps

• Verify chilled water flow.

• Verify remote start / stop or time clock (if installed) has requested the chiller to start.

• Set the chilled water setpoint to the required temperature. (The system water temperature must be greater than the total of the leaving water temperature setpoint plus one-half the control band plus the start-up delta-T before the MicroTech III controller will stage on cooling.)

• Set the Evap Delta T based on a percent of unit nominal flow indicated in Table 12 and the Start Delta T as a starting point. Delta-T=Tons x 24 / gpm

• Check the controller setpoints to be sure that factory defaults are appropriate.

• Put both pumpdown switches (PS1 and PS2) to the ON position.

• Put system switch (S1) to ON position

WARNING

Electrical power must be applied to the compressor crankcase heaters 8 hours before starting unit to eliminate refrigerant

from the oil.

54 IM 1165-1


Table 37: Pumpdown and System Switch Positions

Post Start-up

After the chiller has been operating for a period of time and has become stable, check the following:

• Compressor oil level. (Some scroll compressors do not have oil sight glasses.)

• Refrigerant sight glass for flashing

• Rotation of condenser fans

• Complete the "Compressorized Equipment Warranty Form"

Shutdown

Temporary Shutdown

1 Put both circuit switches to the OFF position (Pumpdown and Stop).

2 After compressors have stopped, put System Switch (S1) to OFF (emergency stop).

3 Turn off chilled water pump. Chilled water pump to operate while compressors are pumping down.

4 To start the chiller after a temporary shutdown, follow the start-up instructions.

Extended Shutdown

1 Front seat both condenser liquid line service valves.

2 Put both circuit switches to the OFF position (Pumpdown and Stop position).

3 After the compressors have stopped, put System Switch (S1) to the OFF position (emergency stop).

4 Front seat both refrigerant circuit discharge valves (if applicable).

5 If chilled water system is not drained, maintain power to the evaporator heater to prevent freezing. Maintain heat tracing on the chilled water lines.

6 Drain evaporator and water piping to prevent freezing.

7 If electrical power to the unit is on, the compressor crankcase heaters will keep the liquid refrigerant out of the compressor oil. This will minimize start-up time when putting the unit back into service. The evaporator heater will be able to function.

8 If electrical power is off, make provisions to power the evaporator heater (if chilled water system is not drained or is filled with suitable glycol). Tag all opened electrical disconnect switches to warn against start-up before the refrigerant valves are in the correct operating position. To start the chiller after an extended shutdown, follow the prestart-up and start-up instructions.

Component Operation

Hot Gas Bypass (Optional)

This option allows the system to operate at lower loads without excessive on/off compressor cycling. The hot gas bypass option is required to be on both refrigerant circuits because of the lead / lag feature of the controller.

This option allows passage of discharge gas into the evaporator inlet (between the TX valve and the evaporator) which generates a false load to supplement the actual chilled water or air handler load.

Note: The hot gas bypass valve will not generate a 100% false load.

The pressure regulating valve is factory set to begin opening at 102 psig with R-410a and can be changed by changing the pressure setting. The adjustment range is 75 to 150 psig. To raise the pressure setting, remove the cap on the bulb and turn the adjustment screw clockwise. To lower the setting, turn the screw counterclockwise. Do not force the adjustment beyond the range it is designed for, as this will damage the adjustment assembly. The regulating valve opening point can be determined by slowly reducing the system load while observing the suction pressure. When the bypass valve starts to open, the refrigerant line on the evaporator side of the valve will begin to feel warm to the touch.

A solenoid valve is located ahead of the bypass valve and is controlled by the MicroTech III controller. It is active when the first stage of cooling on a circuit is active.

VFD Low Ambient Control (Optional)

The optional VFD fan control is used for unit operation below 35 F (2 C) down to a minimum of -10 F (-23.3 C). The control looks at the saturated discharge temperature and varies (pressure) at the "target" temperature. This temperature is established as an input to a setpoint screen labeled "Sat Condenser Temp Target".

Filter-Driers

Each refrigerant circuit is furnished with a replaceable core type filter-drier. The core assembly of the replaceable core drier consists of a filter core held tightly in the shell in a

manner that allows full flow without bypass. Pressure drop across the filter drier must not exceed the following values.

A condenser liquid line service valve is provided for isolating the charge in the condenser, but also serves as the point from which the liquid line can be pumped out. With the line free of refrigerant, the filter-drier core(s) can be easily replaced.

The replaceable cores in the filter drier should be replaced any time the circuit has to be opened. Pressure drop exceeding 10 psi at 100% circuit capacity indicates the drier cores need to be changed.

System Adjustment

To maintain peak performance at full load operation, the system superheat and liquid subcooling may require adjustment. Read the following subsections closely to determine if adjustment is required.

Liquid Line Sight Glass

The color of the moisture indicator is an indication of the dryness of the system and is extremely important when the system has been serviced. Immediately after the system has been opened for service, the element may indicate a wet condition. It is recommended that the equipment operate for approximately 12 hours to allow the system to reach equilibrium before deciding if the system requires a change of drier cores.

Bubbles in the sight glass at constant full load indicates a shortage of refrigerant, a plugged filter-drier, or a restriction in the liquid line. However, it is not unusual to see bubbles in the sight glass during changing load conditions.

Expansion Valve

The expansion valve's function is to keep the evaporator supplied with the proper amount of refrigerant to satisfy the load conditions.

Before adjusting superheat, check that unit charge is correct and liquid line sight glass is full with no bubbles and that the circuit is operating under stable, full load conditions.

The suction superheat for the suction leaving the evaporator is set at the factory for 10 to 12 ºF at full load. To have full rated

unit performance, the superheat must be about 8 ºF at 95°F outdoor ambient temperature.

Crankcase Heaters

The scroll compressors are equipped with externally mounted band heaters located at the oil sump level. The function of the heater is to keep the temperature in the crankcase high enough to prevent refrigerant from migrating to the crankcase and condensing in the oil during off-cycle.

Power must be supplied to the heaters 8 hours before starting the compressors.

Evaporator

On models AGZ-075D through 130D, the evaporator is a compact, high efficiency, dual circuit, brazed plate-to-plate type heat exchanger consisting of parallel stainless steel plates. The evaporator is protected with an electric resistance heater and insulated with 3/4" (19mm) thick closed-cell polyurethane insulation. This combination provides freeze protection down to -20°F (-29°C) ambient air temperature. The water side working pressure of the brazed plate type of evaporator is 653 psig (4502 kPa). Evaporators are designed and constructed according to, and listed by, Underwriters Laboratories (UL).

On models AGZ-140D through -190D, the evaporator is a direct-expansion, shell-and-U-tube type with water flowing in the baffled shell side, and refrigerant flowing through the tubes. The evaporator has an insertion heater and is insulated with 3/4" (19 mm) thick vinyl nitrate polymer sheet insulation, protecting against water freeze-up at ambient air temperatures to -20° F ( 29° C). An water thermostat controls the heater cable. The fitted and glued-in-place insulation has a K factor of 0.28 Btu in/hr ft2 ºF at 75°F. The water side working pressure of the shell-and-tube type of evaporator is 152 psig (1048 kPa). Each evaporator is designed, constructed, inspected, and stamped according to the requirements of the ASME Boiler and Pressure Vessel Code. Double thickness insulation is available as an option.

Phase Voltage Monitor (Optional)

Factory settings are as follows:

• Trip Delay Time: 2 seconds.

• Voltage Setting: set at nameplate voltage.

• Restart Delay Time: 60 seconds.
