In the event ofdamage or shortage, remember that the purchaser isresponsible for filing the necessary claims with thecarrier. Concealed damages not discovered until afterremoving the units from the packaging must bereported to the carrier within 24 hours of receipt.

GENERAL DESCRIPTION:

These Water-to-Air Heat Pumps provide the bestcombination of performance and efficiency available.Safety devices are built into each unit to provide themaximum system protection possible when properlyinstalled and maintained.

The AP Water-to-Air Heat Pumps are UnderwritersLaboratories (UL) and (cUL) listed for safety. The water-to-Air Heat Pumps are designed to operate withentering fluid temperature between 20°F to 80°F in theheating mode and between 50°F to 110°F in thecooling mode.

NOTE: 50°F Min. EWT for well water applications withsufficient water flow to prevent freezing. Antifreezesolution is required for all closed loop applications.Cooling Tower/Boiler and Earth Coupled (Geo Thermal)applications should have sufficient antifreeze solutionto protect against extreme conditions and equipmentfailure. Frozen water coils are not covered underwarranty.

NOTE: This product should not be used fortemporarily heating/cooling during construction. Doingso may effect the units warranty.

MOVING AND STORAGE:

If the equipment is not needed for immediateinstallation upon its arrival at the job site, it should beleft in its shipping carton and stored in a clean, dryarea. Units must only be stored or moved in the normalupright position as indicated by the "UP" arrows oneach carton at all times. If unit stacking is required,stack units as follows: Vertical units less than 6 tons,no more than two high. Horizontal units less than 6tons, no more than three high. "Do not stack unitslarger than 6 tons."

SAFETY CONSIDERATIONS:

Installation and servicing of this equipment can behazardous due to system pressure and electricalcomponents. Only trained and qualified personnelshould install, repair, or service the equipment.Untrained personnel can perform basic functions ofmaintenance such as cleaning coils and replacingfilters.

WARNING: Before performing service ormaintenance operations on the system, turn off mainpower to the unit. Electrical shock could causepersonal injury or death.

When working on equipment, always observeprecautions described in the literature, tags, and labelsattached to the unit. Follow all safety codes. Wearsafety glasses and work gloves. Use a quenching clothfor brazing, and place a fire extinguisher close to thework area.

LOCATION:

Locate the unit in an indoor area that allows easyremoval of the filter and access panels, and hasenough room for service personnel to performmaintenance or repair. Provide sufficient room to makefluid, electrical, and duct connection(s). If the unit islocated in a confined space such as a closet,provisions must be made for return air to freely enterthe space. On horizontal units, allow adequate roombelow the unit for a condensate drain trap and do notlocate the unit above supply piping. These units are notapproved for outdoor installation; therefore, they mustbe installed inside the structure being conditioned. Donot locate in areas that are subject to freezing.

INSTALLATION:

NOTE: Remove all shipping blocks under blowerhousing. Loosen compressor mounting bolts.

MOUNTING VERTICAL UNITS:

Vertical units up tosix tons are availablein left, right, front, orrear air returnc o n f i g u r a t i o n s .Vertical units shouldbe mounted level ona vibration absorbingpad slightly largerthan the base tominimize vibrationtransmission to thebuilding structure. Itis not necessary toanchor the unit to thefloor. (See Figure #1).

MOUNTING HORIZONTAL UNITS:

While horizontal units may be installed on any levelsurface strong enough to hold their weight, they aretypically suspended above a ceiling by threaded rods.The rods are usually attached to the unit corners by

hanger bracket kits(P/N 930-004, 006).(See Figure #2). Therods must be securelyanchored to the ceiling.Refer to the hangingbracket assembly andinstallation instructionsfor details. ModelsAP035 and up require

six brackets (930-006).(See unit horizontal detaildrawing). Horizontal units installed above the ceilingmust conform to all local codes. An auxiliary drain pan

if required by code, should be at least four incheslarger than the bottom of the heat pump. Plumbingconnected to the heat pump must not come in directcontact with joists, trusses, walls, etc.

Some applications require an attic floor installation ofthe horizontal unit. In this case the unit should be setin a full size secondary drain pan on top of a vibrationabsorbing mesh. The secondary drain pan preventspossible condensate overflow or water leakagedamage to the ceiling. The secondary drain pan isusually placed on a plywood base isolated from theceiling joists by additional layers of vibration absorbingmesh. In both cases, a 3/4" drain connected to thissecondary pan should be run to an eave at a locationthat will be noticeable. If the unit is located in a crawlspace, the bottom of the unit must be at least 4" abovegrade to prevent flooding of the electrical parts due toheavy rains.

CONDENSATE DRAIN:

NOTE: If equipped with float style condensateoverflow switch, final adjustment must be made in thefield.

A drain line must be connected to the heat pump and

pitched away from the unit a minimum of 1/8" per footto allow the condensate to flow away from the unit.

This connection must be in conformance with localplumbing codes. A trap must be installed in thecondensate line to insure free condensate flow. (HeatPumps are not internally trapped). A vertical air vent issometimes required to avoid air pockets. (See Figure#3). The length of the trap depends on the amount ofpositive or negative pressure on the drain pan. Asecond trap must not be included.

The horizontal unit should be pitched approximately1/4" towards the drain in both directions, to facilitatecondensate removal. (See Figure #4)

DUCT SYSTEM:

A supply air outlet collar and return air duct flange areprovided on all units to facilitate duct connections.Refer to the FHP individual data specification sheet forphysical dimensions of the collar and flange.

A flexible connector is recommended for supply andreturn air duct connections on metal duct systems. Allmetal ducting should be insulated with a minimum ofone inch duct insulation to avoid heat loss or gain andprevent condensate forming during the coolingoperation. Application of the unit to uninsulated ductwork is not recommended as the unit’s performancewill be adversely affected. Do not connect dischargeducts directly to the blower outlet. The factoryprovided air filter must be removed when using a filterback return air grill.The factory filter should be left inplace on a free return system.

If the unit will be installed in a new installation whichincludes new duct work, the installation should bedesigned using current ASHRAE procedures for ductsizing. If the unit is to be connected to existingductwork, a check should be made to assure that theduct system has the capacity to handle the air requiredfor the unit application. If the duct system is too small,larger ductwork should be installed. Check for existingleaks and repair.

The duct system and all diffusers should be sized tohandle the designed air flow quietly. To maximizesound attenuation of the unit blower, the supply andreturn air plenums should be insulated. There shouldbe no direct straight air path thru the return air grilleinto the heat pump. The return air inlet to the heatpump must have at least one 90 degree turn away fromthe space return air grille. If air noise or excessive airflow are a problem, the blower speed can be changedto a lower speed to reduce air flow. (Refer to ECMmotor interface board section in this manual and Figure#7)

PIPING:

Supply and return piping must be as large as the unitconnections on the heat pump (larger on long runs).Never use flexible hoses of a smaller inside diameterthan that of the fluid connections on the unit. AP unitsare supplied with either a copper or optional cupro-nickel condenser. Copper is adequate for ground waterthat is not high in mineral content. Should your welldriller express concern regarding the quality of the wellwater available or should any known hazards exist inyour area, we recommend proper testing to assure thewell water quality is suitable for use with water sourceequipment. In conditions anticipating moderate scaleformation or in brackish water a cupro-nickel heatexchanger is recommended.

Both the supply and discharge water lines will sweat ifsubjected to low water temperature. These lines shouldbe insulated to prevent damage from condensation.

3AP SERIES

(Figure #3)

(Figure #4)

All manual flow valves used in the system must be ballvalves. Globe and gate valves must not be used due tohigh pressure drop and poor throttling characteristics.Never exceed the recommended water flow rates asserious damage or erosion of the water to refrigerantheat exchanger could occur.

Always check carefully for water leaks and repairappropriately. Units are equipped with female pipethread fittings. Consult the specification sheets forsizes. Teflon tape sealer should be used whenconnecting water piping connections to the units toinsure against leaks and possible heat exchangerfouling. Do not overtighten the connections. Flexiblehoses should be used between the unit and the rigidsystem to avoid possible vibration. Ball valves shouldbe installed in the supply and return lines for unitisolation and unit water flow balancing.

ELECTRICAL:

(Refer to electrical component box layout, Figure #5)

Field wiring must comply with local and nationalelectric codes. Power to the unit must be within theoperating voltage range indicated on the unitnameplate or on the performance data sheet. On threephase units (single stage units only) phases must bebalanced within 2%.

CAUTION: Operation of unit on improper line voltageor with excessive phase imbalance will be hazardous tothe unit, constitutes abuse and may void the warranty.

Properly sized fuses or HACR circuit breakers must beinstalled for branch circuit protection. See unitnameplate for maximum fuse or breaker size.

The unit is provided with a concentric knock-out in thefront left corner post for attaching common trade sizesof conduit, route power supply wiring through thisopening. Always connect the ground lead to thegrounding lug provided in the control box and powerleads to the power supply terminal block as indicatedon the wiring diagram and Figure #5.

NOTE: Units supplied with internal electric heatrequire two (2) separate power supplies: one for theunit compressor and one for the electric heaterelements, blower motor and control circuit. Refer to theELECTRIC HEATER PACKAGE OPTION section andFigure #9 for wiring instructions, minimum circuitampacities and maximum fuse/breaker sizing.

ECM INTERFACE BOARD:

THERMOSTAT CONNECTIONS:

Thermostat wiring is connected to the 10 pin screwtype terminal block on the lower center portion of theECM Interface Board. In addition to providing aconnecting point for thermostat wiring, the interfaceboard also translates thermostat inputs into controlcommands for the variable speed programmable ECMDC fan motor and displays an LED indication ofoperating status. The thermostat connections and theirfunctions are as follows:

If the unit is being connected to a thermostat with amalfunction light, this connection is made at the unitmalfunction output or relay.

NOTE: If the thermostat is provided with a malfunctionlight powered off of the common (C) side of thetransformer, the unit must be provided with amalfunction relay (FHP option # 660-006) to properlyenergize the light. The relay coil will be wired acrossthe (ALR) and (C) contacts on the unit’s UPM boardand the relay’s normally open contacts across (ALR)and the malfunction light connection on thethermostat. If the thermostat is provided with amalfunction light powered off of the hot (R) side of thetransformer, then the thermostat malfunction lightconnection should be connected directly to the (ALR)contact on the unit’s UPM board.

To the left of the thermostat connection block are arow of 2 red and 4 green LED’s. These LED’s indicatethe operating status of the unit. They are labeled asfollows:

EM (red) Emergency Heat OnW1 (red) Auxiliary Heat OnO (green) Reversing Valve Energized, unit is

in cooling modeY2 (green) Second Stage Compressor OnY1 (green) First Stage Compressor OnG (green) Fan On

Just above the connector block is a single red LEDlabeled CFM that will blink intermittently when the unitis running and may flicker when the unit is off. This LEDindicates the air delivery of the blower at any giventime. Each blink of the LED represent 100 CFM of airdelivery so if the LED blinks 12 times, pauses, blinks 12times, etc. the blower is delivering 1200 CFM. Refer toFigure #7 for factory programmed air delivery settingsfor the ES Series.

To the right of the thermostat connection block is agreen LED labeled dehumidify.

Just above and to the right of the thermostatconnection block are four sets of jumper pins labeledADJ, DELAY, HEAT and COOL. The ADJ set of pins arelabeled NORM, (+), (-) and TEST. ES units will all be seton the NORM position from the factory, however,airflow can be increased (+) or decreased(-) by 15% from the pre-programmed setting byrelocating the jumper in this section. The TEST positionis used to verify proper motor operation. If a motorproblem is suspected, move the ADJ jumper to the

TEST position and energize G on the thermostatconnection block. If the motor ramps up to 100%power, then the motor itself is functioning normally.Always remember to replace the jumper to NORM, (+)or (-) after testing and reset the unit thermostat torestore normal operation.

NOTE: Do not set the ADJ jumper to the (-) settingwhen electric heaters are installed. Doing so maycause the heaters to cycle on their thermal overloadswitches, potentially shortening the life of the switches.

The other three sets of jumper pins are used to selectthe proper program in the ECM motor for the unit.Refer to Figure #7 for the proper jumper placement.

NOTE: Always disconnect power before changingjumper positions on the interface board and reset theunit afterward.

To the left of the red and green status LED’s isa row of 1/4” male quick connects. These areused to pass thermostat inputs on to the restof the control circuit. Remember to always turnoff unit power at the circuit breaker beforeattaching or disconnecting any wiring fromthese connections to avoid accidental shortcircuits that can damage unit controlcomponents.

SAFETY DEVICES AND THE UPMCONTROLLER

Each unit is factory provided with a Unit ProtectionModule (UPM) that controls the compressor operationand monitors the safety controls that protect the unit.

Safety controls include the following:

• High pressure switch located in the refrigerantdischarge line and wired across the HPC terminals onthe UPM

• Low pressure switch located in the unit refrigerantsuction line and wired across terminals LPC1 and LPC2on the UPM.

• Optional freeze protection sensor located on the leavingside of the water coil prevents unit operation below 35ºF. A freeze stat pin located on the board may be put inthe YES or NO position depending whether the freezestat is ordered.

NOTE: The factory default is in the YES position. If thefreeze stat option is not ordered the pin must berelocated to the NO position.

• RANDOM START – Each controller has a uniquerandom start delay ranging from 270 to 300 seconds.

• LOW PRESSURE BYPASS TIMER - The lowpressure switch is bypassed for 120 seconds aftercompressor start-up to prevent nuisance low pressurelockouts during cold start-up in the heating mode.

• BROWNOUT/SURGE/POWER INTERRUPTIONPROTECTION – a 20 millisecond window is monitoredfor the above condition. Should any of these conditionsbe detected, the 5-minute delay on break timer and therandom start timer delay are initiated.

• MALFUNCTION OUTPUT – The controller has a set ofwet contacts for remote fault indication.

• TEST SERVICE PIN – A jumper pin is provided toreduce all time delay settings to 5 seconds duringtroubleshooting or verification of unit operation. Notethat operation of the unit in test mode can lead toaccelerated wear and premature failure of the unit.

• L.E.D. FAULT INDICATION – Two L.E.D. indicatorsare provided:

• GREEN: Power L.E.D. indicates 18 – 30 VAC presentat the board.

• RED: Fault indicator with blink codes as follows:

•• ONE BLINK High pressure lockout

•• TWO BLINKS Low pressure lockout

•• THREE BLINKS Freeze sensor lockout

•• FOUR BLINKS Condensate overflow

•• FIVE BLINKS Brown out

The fault pulse code may be sent to the ALR faultterminal by placing the Alarm Output pin in thepulse position. The pulse signal may be sent to a

thermostat with a fault indication LED (24v) and willdisplay the fault code on the thermostat.

• INTELLIGENT RESET - If a fault condition is initiatedthe 5 minute delay on break time period and therandom start timer are initiated and the unit will restartafter these delays expire. During this period the faultLED will indicate the cause of the fault. If the faultcondition still exists or reoccurs before 60 minutes, theunit will go into a hard lockout and requires a manuallockout reset. A condensate overflow fault will causethe unit to go into a hard lockout immediately.

• LOCKOUT RESET - A hard lockout can be reset byturning the unit thermostat off and then back on or byshutting off unit power at the circuit breaker.

NOTE: The blower motor will remain active during alockout condition.

ELECTRIC HEATER PACKAGE OPTION:

Factory or field installed internal electric heaterpackages are available for all Aquarius II series units.Two power supplies are required when heaterpackages are utilized. The power supply for the heaterpackage (located in the electric heater package controlbox) provides power for the heater elements, theblower motor and the control circuit for the unit. Thepower supply for the unit provides power for thecompressor. This allows the electric heaters tocontinue to operate along with the blower motor in thecase of unit compressor and/or compressor powersupply failure. See HP Series Heater Kit Instructions forfield installation.

Each Aquarius II model has a number of heater sizesavailable. Refer to Figure #9 for heater packagecompatibility with specific Aquarius II units, modelnomenclature and electrical data.

7AP SERIES

SEQUENCE OF OPERATION-TWO STAGE UNITS:(Figure #13 Wire Schematic)

COOLING MODE:

Energizing the “O” terminal energizes the unit reversingvalve in the cooling mode. The fan motor starts whenthe “G” terminal is energized. Note that the fan motorwill take 30 seconds to ramp up to operating speedand will run at fan only rated air flow as long as there isno call for compressor or heater operation.

When the thermostat calls for first stage cooling (Y1)the loop pump or solenoid valve if present is energizedand the first stage of compressor capacity starts. Thefan ramps up to first stage cooling air flow in 30seconds.

When the thermostat calls for second stage cooling(Y2) the second stage (or full compressor capacity) isinitiated. The fan ramps up to full cooling air flow.

Once the thermostat is satisfied, the compressor shutsdown accordingly and the fan ramps down to either fanonly mode or off over a span of 30 seconds.

Note that a fault condition initiating a lockout will de-energize the compressor irrespective of which stage isengaged.

HEATING MODE:

The first two stages of heating (Y1 & Y2) operate in thesame manner as cooling, but with the reversing valvede-energized. On a call for auxiliary heat (W1), the fanramps up to auxiliary heat air flow immediately and theelectric heater package is energized along with thecompressor. As the thermostat is satisfied, the heaterswill shut off as soon as W1 is de-energized, and thecompressors will remain on until the thermostat stagesare satisfied. Note that if the unit compressor lock outfor any reason at this time, the electric heaters willcontinue to function normally.

Once the thermostat is satisfied, the compressor shutsdown and the fan ramps down either fan only mode oroff over a span of 30 seconds. If emergency heat(W2/EM) is called for, the fan will ramp up toemergency heat air flow immediately and the heaterpackage will energize in emergency heat mode, allheater elements coming on. On shut down the fan willramp down over a period of 30 seconds.

WELL WATER SYSTEMS:(Figure #10)

Copper is adequate for ground water that is not high inmineral content. Should your well driller expressconcern regarding the quality of the well wateravailable or should any known hazards exist in yourarea, we recommend proper testing to assure the wellwater quality is suitable for use with water sourceequipment. In conditions anticipating moderate scaleformation or in brackish water a cupro-nickel heatexchanger is recommended. In well water applicationswater pressure must always be maintained in the heatexchanger. This can be accomplished with either

control valve or a bladder type expansion tank. Whenusing a single water well to supply both domestic waterand the heat pump care must be taken to insure thatthe well can provide sufficient flow for both. In wellwater applications a slow closing solenoid valve mustbe used to prevent water hammer.

Solenoid valves should be connected across Y1 andC1 on the interface board for all. Make sure that the VAdraw of the valve does not exceed the contact rating ofthe thermostat.

INSTALLATION OF PRESSUREREGULATING VALVES:

Pressure regulating valves are used to increase ordecrease water flow through the heat pump inresponse to refrigerant pressure. In some cases morewater may be required in heating than in cooling, orvice versa. With the Aquarius II heat pumps thesevalves are not required. However, if installed, a pair ofvalves are required for proper operation, one valve forcooling (direct acting) and another valve for heating(indirect acting). A refrigerant tap is provided in therefrigerant line located between the reversing valve andthe water-to-refrigerant heat exchanger for propermonitoring of the refrigerant pressures.

The discharge water from the heat pump is notcontaminated in any manner and can be disposed of invarious ways depending on local building codes (i.e.discharge well, dry well, storm sewer, drain field,stream or pond, etc.) Most local codes forbid the useof a sanitary sewer for disposal. Consult your localbuilding and zoning department to insure compliancein your area.

COOLING TOWER/BOILER SYSTEMS:

(Figure #11)

The cooling tower and boiler water loop temperature isusually maintained between 50˚ F to 100 ˚ F to assureadequate cooling and heating performance.

In the cooling mode, heat is rejected from the FHP unitinto the water loop. A cooling tower providesevaporative cooling to the loop water thus maintaininga constant supply temperature to the unit. Whenutilizing open cooling towers, chemical water treatmentis mandatory to ensure the water is free from corrosiveelements. A secondary heat exchanger (plate frame)between the unit and the open cooling tower may alsobe used. It is imperative that all air be eliminated fromthe closed loop side of the heat exchanger to insureagainst fouling.

In the heating mode, heat is absorbed from the waterloop. A boiler can be utilized to maintain the loop at thedesired temperature.

CAUTION: Water piping exposed to extreme lowambient temperatures is subject to freezing.

Consult the specification sheets for piping sizes. Teflontape sealer should be used when connecting to the unitto insure against leaks and possible heat exchangerfouling. Do not overtighten the connections. Flexible

8 AP SERIES

hoses should be used between the unit and the rigidsystem to avoid possible vibration. Ball valves shouldbe installed in the supply and return lines for unitisolation and unit water flow balancing.Pressure/temperature ports are recommended in bothsupply and return lines for system flow balancing.Water flow can be accurately set by measuring thewater-to-refrigerant heat exchangers water sidepressure drop. See specification sheets for water flowvs. pressure drop information.

No unit should be connected to the supply or returnpiping until the water system has been completelycleaned and flushed to remove any dirt, piping chips orother foreign material. Supply and return hoses shouldbe connected together during this process to ensurethe entire system is properly flushed. After the cleaningand flushing has taken place the unit may beconnected to the water loop and should have all valveswide open.

EARTH COUPLED SYSTEMS:

(Figure #12)

Closed loop and pond applications require specializeddesign knowledge.No attempt at these installationsshould be made unless the dealer has receivedspecialized training. Utilizing FHP’s Ground LoopPumping Package (GLP), makes the installation easy.Anti-freeze solutions are utilized when low evaporatingconditions are expected to occur. Refer to the GLPinstallation manuals for more specific instructions.

SYSTEM CHECKOUT:

• After completing the installation, and before energizingthe unit, the following system checks should be made:

• Verify that the supply voltage to the heat pump is inaccordance with the nameplate ratings.

• Make sure that all electrical connections are tight andsecure.

• Check the electrical fusing and wiring for the correctsize.

• Verify that the low voltage wiring between thethermostat and the unit is correct.

• Verify that the water piping is complete and correct.• Check that the water flow is correct, and adjust if

necessary.• Check the blower for free rotation, and that it is secured

to the shaft.• Verify that vibration isolation has been provided.• Unit is serviceable. Be certain that all access panels are

secured in place.

UNIT START-UP:

1. Set the thermostat to the highest setting.

2. Set the thermostat system switch to "COOL", and thefan switch to the "AUTO" position. The reversing valvesolenoid should energize. The compressor and fanshould not run.

3. Reduce the thermostat setting approximately 5 degreesbelow the room temperature.

4. Verify the heat pump is operating in the cooling mode.

5. Turn the thermostat system switch to the "OFF"position. The unit should stop running and the reversingvalve should deenergize.

6. Leave the unit off for approximately (5) minutes to allowfor system equalization.

7. Turn the thermostat to the lowest setting.

8. Set the thermostat switch to "HEAT".

9. Increase the thermostat setting approximately 5degrees above the room temperature.

10. Verify the heat pump is operating in the heating mode.

11. Set the thermostat to maintain the desired spacetemperature.

12. Check for vibrations, leaks, etc...

MAINTENANCE:

1. Filter changes or cleanings are required at regularintervals. The time period between filter changes willdepend upon type of environment the equipment isused in. In a single family home, that is not underconstruction, changing or cleaning the filter every 60days is sufficient. In other applications such as motels,where daily vacuuming produces a large amount of lint,filter changes may be need to be as frequent asbiweekly.

WARNING: Equipment should never be used duringconstruction due to likelihood of wall board dustaccumulation in the air coil of the equipment whichpermanently affects the performance and mayshorten the life of the equipment.

2. An annual “checkup” is recommended by a licensedrefrigeration mechanic. Recording the performancemeasurements of volts, amps, and water temperaturedifferences (both heating and cooling) is recommended.This data should be compared to the information on theunit’s data plate and the data taken at the originalstartup of the equipment.

3. Lubrication of the blower motor is not required,however may be performed on some motors to extendmotor life. Use SAE-20 non-detergent electric motor oil.

4. The condensate drain should be checked annually bycleaning and flushing to insure proper drainage.

5. Periodic lockouts almost always are caused by air orwater flow problems. The lockout (shutdown) of the unitis a normal protective measure in the design of theequipment. If continual lockouts occur call a mechanicimmediately and have them check for: water flowproblems, water temperature problems, air flowproblems or air temperature problems. Use of thepressure and temperature charts for the unit may berequired to properly determine the cause.
