GeneralInformation

Literature Contents

This manual describes the installationof VariTrane VAV units with recom-mended wiring, piping, and mountingof Single-Duct, Dual-Duct, Fan-Pow-ered, Low-Height terminal units anddiffusers.Receiving and Handling

VariTrane Units are shipped completelyassembled with the exceptions ofoptional attenuators for fan-poweredunits and accessories.Upon receiving the equipment,complete the following:

Locate the nameplate and refer to themodel and sales order number andcheck that the correct units have beendelivered.

Inspect the control enclosures and airvalve casing for dents or punctures.

UnitInformation

Single-Duct Units

The basic unit consists of a sheet metalcasing with an air valve, which is usedto modulate the air being delivered intothe occupied zone. The unit is designedto modulate either cooling or heatingair between the temperatures of 40°Fand 140°F. Air enters the air valvethrough the round or rectangular inletand exits into the sheet metal casing tobe distributed to the zone eitherthrough integral round outlets in thecasing or through rectangular ductattached to the discharge of the unit.The basic unit can also be ordered withfactory-mounted electric or hot waterheating coils attached to the discharge.(See Figure 1.)

These re-heat units are used primarilyto reheat air-to-zone temperature whenthe load in the occupied space is low.

Primary air is modulated through theVariTrane air valve by rotating thedamper blade. All air valves have around/rectangular inlet for easy fit-upwith incoming ductwork.

Figure 1 – Typical Single-Duct Units Dual-Duct Units

Dual-duct units provide two air valves:one as heating primary air and theother as cooling primary air. Bothdischarge into the common outlet,which leads to the zone being con-trolled. (See Figure 2.)The units are provided with a slip anddrive rectangular duct connection orcan be ordered with integral outletplenum.

Sequencing of the hot and cold airvalve is dependent upon jobrequirements. One typical control is thevalves working in conjunction with eachother to respond to zone temperature.

When the cooling valve becomes fullyclosed or reaches a specified minimum,then the heating valve will begin tomodulate or vice versa. The typicalresult is that air flowing to the zonevaries from the maximum down to aminimum and back up to a maximumas the load varies and as the controlswould cause one air valve to close andthe other to open.

Another typical application is when theunit provides a constant volume to thezone. When the zone sensor is tieddirectly to the heating valve, it willmodulate the heating valve accordingto the zone temperature.

When the heating valve is fully closedor there is a call for cooling in the zone,the cooling valve will be at constantsupply. As the space becomes too cool,the heating valve will modulate open,decreasing the cooling valve flow. Thetypical result is that the air flowing intothe zone stays at a constant flowwhether the unit is heating or cooling.

UnitInformation

Fan-Powered and Fan-PoweredLow-Height Units

VariTrane fan-powered and low-heightfan-powered units can be either parallelor series, with or without re-heat. (SeeFigure 3.)The fan on a series unit runscontinuously whenever the main airhandler unit is in operation. There arevarious options for starting the fan. Thefan can be started three ways: 1)remotely, 2) by a duct pressure switch,or 3) by a combination of both. Theparticular fan control method may varyfrom unit to unit, depending upon jobneeds.

Typically, the heater is off while the airvalve modulates primary air andresponds to zone temperature. If zonetemperature decreases to the pointwhere a decrease in primary air will notmaintain the desired temperature, there-heat will be activated to increase thetemperature of the discharge air.

On a parallel unit, the VariTrane air valvedelivers primary cooling air to the unitoutlet. When the space temperaturedecreases beyond air valve control, thefan is turned on as the first stage ofheat. The fan delivers plenum air fromabove the occupied space to the unitoutlet, which is mixed with primary airand delivered to the occupied space.

Note: Either the fan, the air valve, or bothcan deliver airflow into the occupiedspace. In order to prevent primary airflowfrom exiting through the fan when thefan is not running on a parallel unit, aback draft damper is provided. When thefan is not running, the efficiency of thissystem is the same as a standard single-duct VAV unit.

Typically, the control systems applied toparallel units cause the air valve toclose to zero or a minimum flow beforethe fan is activated. After the fan isactivated, the optional heat will beactivated upon further reduction inzone temperature. Therefore, minimalprimary air is mixed with the heated air.

VariTrane fan-powered unit fan sizes02SQ–05SQ and 08SQ–10SQ wereperformance tested at .12 in. w.g. andsizes 06SQ and 07SQ were tested at .15in. w.g. Units are not designed tooperate unducted and below thesetested static pressures.

Note: Fan-powered units are availablewith rectangular discharge connectiononly. The optional heater is mounted onthe discharge of the unit. Hot water coilsare connected to either the plenum inletor on the discharge on parallel units, andto the discharge of series units.

UnitInstallation

Due to their weight, the VAV terminalunits should be suspended from theuppermost ceiling, independent of thefalse ceiling grid. Suspension devicesare to be supplied by the installer. Unitsmust be installed level and upright.Failure to level the unit properly mayprevent proper operation of thecontrols and/or terminal unit. Units arenot designed to be installed vertically.Consequently, this will also void the ULratings and any warranty on the unit.Single-Duct

Depending upon the size and weight ofthe single-duct unit, it may be capableof being supported by the ductworkthat is connected to it. No hangerbrackets are provided on these unitssince the unit should be supported bymeans of a hanger strap. The hangerstrap should be secured directly to theunit casing as shown in Figure 4.For cooling only single-duct units orsingle-duct units with hot water coil, theunt may be rotated 180° for oppositeside connections.

For units with electric heat, the unitmust be ordered from the factorydesignating either right- or left-handconnections.

Dual-Duct

Dual-duct units should be supported byeither hanger straps or by using athreaded rod in conjunction with thehanger brackets that are provided onthe unit. See Figure 5.

UnitInstallation

VAV-SVN01E-EN 31

Duct Connections

All VariTrane units should be providedwith a minimum of 1.5-duct diametersof straight duct prior to the inlet of theunit. It is recommended that at least 48inches of straight duct be providedfrom the discharge of the units prior toany take-offs or transitions. This is arequirement for electric heat fan-powered units used inapplications with 100%downward discharge.

Note: In order to maintain the UL ratingfor VariTrane electric coils, there must befour feet of straight unlined ductworkdownstream of the reheat coil prior toany diffuser takeoffs.

After all connections are made, checkthat the entire ductwork system isairtight. In some high-pressuresystems, duct sealer may be necessary.

Provide insulation around the entireinlet collar (all the way to the unitcasing).

Use caution not to damage the flowtubes when making ductworkconnections or insulating.

Cut “slits” in the insulation for the flowtubes and secure with duct tape.

If the unit is to be installed in a locationwith high humidity, external insulationaround the heating coil should beinstalled as required.

Water Coil Connections

Water coil piping connections will be3/8” or 7/8” OD.

If necessary, you can change the coilconnection from left-handed to right-handed (and vice-versa) bydisconnecting the coil from the unitand rotating the coil “like a steeringwheel” 180°.

The inlet piping should always beconnected to the bottom connection ofthe coil regardless of handedness.

Care should be taken to properlysupport the water coil pipingconnections while connecting theadjoining pipe.

It is recommended that piping to thewater coil should be done after field-mounted controls, external insulation,and ductwork connections have beencompleted.

Do not connect water valve or pipeextensions to the water coilconnections unless supported.

Unit Accessibility

Single-duct and dual-duct unitsprovided with hot water reheat have anaccess panel located on the side of thewater coil. All other single-duct anddual-duct units are provided withoutaccess, as all functioning componentsare external to the unit.

Fan-powered terminals are providedwith a sliding side access.

Low-height terminal units have aremovable bottom panel.

Clearances

For proper service, it is recommendedthat at least 36” of side clearance beprovided to service and access single-duct and dual-duct terminals units.

Fan-powered VAV units have a plenuminlet that must be clear of obstructions.Allow at least 36” of clearance in frontof the side access and plenum opening.

Low-height fan-powered terminalsrequire the same plenum clearancerequirement that applies to thestandard fan-powered units. Howeverthe access to the internal componentsis located on the bottom of the unit.

It is also recommended that 6” ofclearance be provided to the top andbottom of all the units.

Note: The minimum clearance forcontrols and heater controls should be36” for all models except units with 575-volt electric heaters, which require 48” ofclearance. NEC and/or local codesoverride all clearance requirements.

Actuator Mounting

Trane offers a factory-mounted actuatorwith a 90-second drive time. Theactuator drives 1 degree per second. Afield-installed actuator may be used ifdesired. The actuator shaft has a ½-inchdiameter and is designed to travelclockwise to close the damper andcounter-clockwise to open the damper.There is an indicator on the end of theactuator shaft that can be used todetermine the position of the damper.

UnitInstallation

Equipment DamageNote: When installing or replacing theactuator tighten the actuator set screwper the manufacturer’s instructions.Failure to follow the manufacturer’sspecifications may result in unitmalfunction.

Figure 18 – ECM Control Board

(SCR) Motor Speed ControlAdjustment Procedure.

In order to make units more convenientand efficient to balance, an SCR(silicone control rectifier) is provided asstandard on all fan-powered units.

The SCR is located on the side of thefan control box. To adjust the speed ofthe motor, the external knob must berotated either clockwise orcounterclockwise depending on thedesired speed adjustment.

There is an internal potentiometer(Figure 14) setting on the SCR controllerthat can be accessed by removing thecontrol box cover. This internalpotentiometer is set at the factory to thespecific motor voltage.It may be necessary to adjust this in thefield depending on the building’s powerfactor. NOTE: Do not set this potentiometer

below the voltage of the fan motor.

Figure 17 – Internal Potentiometer Electrically Commutated Motor (ECM)

Trane offers an energy efficient ECMmotor as a motor option. Balancing ofan ECM motor is accomplishedthrough electronic control adjustmentson the ECM control board (see Figure15). Potentiometer settings for amultitude of CFM settings are given inCharts 4–15. Other potentiometersettings can be determined either byinterpolating from these tables or byusing the following equation:

CFMsetting = CFMmin +{(Potentiometer Setting) x [(CFMmax -CFMmin)/100]}

There is an LED on the ECM controlboard, which will blink one time forevery 100 CFM of motor setting. Forexample, the LED on a unit set for 790CFM will blink 7 times. The LED on aunit set for 800 CFM will blink 8 times.

NOTE: This feature only verifies that theCFM is set properly. This feature doesnot indicate at what speed the motor isactually running.

The ECM must be “load tested.” In otherwords, the fan must be connected toproperly test the ECM.

Maintenance

Periodic maintenance of the VariTraneproduct is minimal, but necessary forefficient operation. Routine mainte-nance consists of inspecting/replacingthe air filters of the fan-poweredterminals.Motors

Both the PSC (permanent split capaci-tor) and the ECM (Electrically Commu-tated Motor) require no lubricationduring its normal life of operation.Fan Wheel:

Periodically, the fan wheel should beinspected for dirt or debris and cleanedas necessary.Filter

The filter on fan-powered terminals willneed to be inspected/replaced routinelydepending on the environmentalconditions of the plenum.Water Coil

Water coils should be inspected and thefins should be cleaned periodically.Water coils have been provided with anaccess panel as standard to assist withinspection and cleaning.

Fan Motor Replacement

Standard height fan-powered seriesand parallel fan motors are replaceablethrough the filter opening and thestandard sliding side access panel. Toaccess the fan motor, the fan housingmust be detached by removing themounting bolts that hold the housing tothe fan board. Removing the entirehousing allows the fan motor, fanhousing, and fan wheel to be re-alignedon a workbench or floor and preventany possible fan wheel rubbing thatmay occur. Removing the housing willprovide access to the motor shaft setscrew that holds the fan wheel to themotor shaft.The low-height fan assembly wasdesigned with an inlet ring that assistswith removal of the fan motor. Toaccess the fan motor assembly, thebottom panel must be removed. Theinlet ring is held in place by six boltsand three motor mount bolts. Removethese bolts and the motor and fanwheel will come out of the fan housing.

Figure 27 – Standard Motor Removal

WARNINGWARNING

WARNINGWARNINGRotating Components!Disconnect all electric power, includingremote disconnects before servicing.Follow proper lockout/tagout proce-dures to ensure the power cannot beinadvertently energized. Failure todisconnect power before servicingcould result in death or serious injury.

Hazardous Voltagew/Capacitors!Disconnect all electric power, includingremote disconnects and discharge allmotor start/run capacitors beforeservicing. Follow proper lockout/tagoutprocedures to ensure the power cannotbe inadvertently energized. Verify withan appropriate voltmeter that allcapacitors have discharged. Failure todisconnect power and dischargecapacitors before servicing could resultin death or serious injury.

Installationof Diffusers

General

All units must be installed upright andlevel as indicated by the arrow on theside of the units. Return air slots shouldbe placed perpendicular and offset tothe slot diffusers to avoid short-circuiting of air distribution patterns.Place the unit in its approximate finalposition and check that it is upright andlevel. For single- slot units, engagethe back of the diffuser over the t-barwith an edge and both ends resting onthe t-bar. For double-slot units, slidethe unit over the t-bar. For center-notch units, place diffuser over thet-bar, straddling it across a t-bar andresting on the units ends.

If the unit has a fire damper, make surethat the damper is still fully open.Diffuser discharge must always beflush with the ceiling tiles to assure theproper airflow (Coanda effect).

Diffusers require specific installationinformation when mounting to adesired ceiling type. Select the ceilingtype that closely matches the job siteapplication and use the followingprocedures.

T-Bar Ceiling

Finish installation of the diffuser in t-barceiling. (See Figure 29.) Follow theseprocedures before the ceiling construc-tion is completed.

1.Position the diffuser at each end restingdirectly on the structural t-bar forsupport and the t-bar fitting into thechannel provided at the unit dischargeair throw.

2.A ceiling tile support flange is providedon each side of the discharge slot of theunit. Trim ceiling tile approximately 1½inches each to allow for width ofdischarge slot. For revealed edgeceilings, tile must be cut in a “Z”pattern.

3.Install ceiling tiles in usual manner withcut edges resting on the flanges of theair slot.

Figure 29 – Diffuser Installation in T-BarCeiling

Concealed Spline Ceiling

Follow these procedures to finishinstallation of control and satellitediffusers and concealed spline forsuspension ceilings before completingthe ceiling construction (Figure 30).Place the units in their approximatefinal positions. If using the trim anglediffuser, its slots must be even with thespline level. If applying the trimaccessory, the bottom of the diffusermust be level with the finished ceiling.

If installing the trim accessory, insertthe trim into the ceiling opening frombelow and engage the diffuser slot tothe trim t-bar structure. With bottomflange of trim accessory against theceiling, and using the pre-drilled holesin the flange as a guide, drill holes in theflange of the diffuser. Join the diffuserand trim accessory with self-tapingsheet metal.

Figure 30 – Diffuser with TrimAccessory Installation in ConcealedSpline Ceiling

CAUTIONCAUTION

Drywall/Plaster Ceiling

Finish installation of diffusers in plasterceiling. Follow these procedures beforecompleting the ceiling construction(Figure 31).
