IImmppoorrttaanntt:: Installation of this unit shall be made inaccordance with the National Electric Code,NFPA No. 90A and 90B, and any other localcodes or utilities requirements.

IImmppoorrttaanntt:: Air handlers do not require repositioning ofthe coil or drain pan for upflow orhorizontal left applications. See thedownflow and horizontal right installationsections for application instructions.

NNoottee:: Air handlers have been evaluated in accordancewith the Code of Federal Regulations, ChapterXX, Part 3280 or the equivalent. “SUITABLE FORMOBILE HOME USE.”

NNoottee:: Condensation may occur on the surface of the airhandler when installed in an unconditionedspace. When units are installed in unconditionedspaces, verify that all electrical and refrigerantline penetrations on the air handler are sealedcompletely.

NNoottee:: The manufacturer recommends installing ONLYA.H.R.I approved, matched indoor and outdoorsystems. Some of the benefits of installingapproved matched indoor and outdoor splitsystems are maximum efficiency, optimumperformance, and the best overall systemreliability.

Installation Instructions

1. UUnnppaacckkiinngg

Carefully unpack the unit and inspect the contentsfor damage. If any damage is found at the time ofdelivery, proper notification and claims should bemade with the carrier.

Check the rating plate to assure model number andvoltage, plus any kits match with what you ordered.The manufacturer should be notified within 5 daysof any discrepancy or parts shortage.

2. LLooccaattiioonn

The air handler should be centrally located and maybe installed in a closet, alcove, utility room,basement, crawl space or attic. Minimumclearances must be met.

IImmppoorrttaanntt:: The downflow sub-base may berequired with electric heat applications.See minimum clearance table.

IImmppoorrttaanntt:: A downflow condensate managementkit BAYTEMDFKT1A is required andmust be ordered separately fordownflow applications of all 5-ton airhandlers.

The unit should be installed in a level position toensure proper condensation drainage. Up to anadditional 1/4” rise over the width or depth of theunit is allowed to create additional sloping towardsthe drain. Unit must be positioned between leveland ¼” rise, sloping toward the drain connections.

When the unit is installed in a closet or utility room,the room should be large enough, and have anopening to allow replacement of the unit. Allservicing is done from the front and a clearance of21" is needed for service unless the closet dooraligns with the front of the air handler.

If you are installing the unit in an unconditionedspace such as an attic or crawl space, you mustensure that the area provides sufficient aircirculation to prevent moisture collection on thecabinet during high dew point conditions. A drainpan must be installed under the entire unit when itis installed in or above a finished ceiling or in anunconditioned space.

3. DDuucctt WWoorrkk

The duct work should be installed in accordancewith the NFPA No. 90A "Installation of AirConditioning and Ventilating systems" and No. 90B"Residential Type Warm Air Heating and AirConditioning Installation."

The duct work should be insulated in accordancewith the applicable requirements for the particularinstallation as required by HUD, FHA, VA theapplicable building code, local utility or othergoverning body.

4. CCoonnddeennssaattee DDrraaiinn

The unit is supplied with primary and auxiliarycondensate drains that have 3/4" NPT connections.The primary drain must be trapped outside the unitand piped in accordance with applicable buildingcodes.

The figure shows the operation of a properlydesigned trap under normal operating conditionswhen the blower is running and the condensate isdraining. Note the difference in height of the watercolumn must at least equal the normal negativestatic pressure existing during operation betweenthe cooling coil and blower. It is advisable to havethe difference in water column height somewhatgreater than the normal maximum operating staticto allow for greater static caused by dirty filters orfor the bounce of the water column on start up.

Proper operation of condensate trap undernormal operating conditions.

“A” height of water column equalsnegative static pressure existing in system.

“C” dimension should at least equal twotimes the maximum negative static pressurethat can occur in system.

Do not reduce the drain line size less than theconnection size on the drain pan. Condensateshould be piped to an open drain or to the outside.All drains must pitch downward away from the unita minimum of 1/4" per foot of line to ensure properdrainage.

IImmppoorrttaanntt:: If cleanout Tee is used, stand pipe mustbe sealed/capped.

IImmppoorrttaanntt:: If a vent Tee is used, it must bedownstream from the trap.

Insulate the primary drain line to prevent sweatingwhere dew point temperatures may be met.(Insulation is optional depending on climate andapplication needs.)

5. RReeffrriiggeerraanntt PPiippiinngg

Refrigerant piping external to the unit shall be sizedin accordance with the instructions of themanufacturer of the outdoor equipment.

6. MMeetteerriinngg DDeevviiccee

3 through 5 ton units are shipped and installed withan internally-checked, bleed TXV designed for airconditioning or heat pump operation. Chargesystems with indoor TXV using the subcoolingmethod as recommended in the outdoor unitInstaller’s Guide. Pressures equalize after shutdown. Some outdoor models may require a startassist kit. See outdoor unit for more information.

1.5 through 2.5 ton units are shipped and installedwith an orifice piston sized for nominal tonnage.Charge systems with indoor fixed orifice piston bythe superheat method using the superheat chargingtable. See Table “Fixed Orifice Superheat ChargingTable,” p. 21

7. BBlloowweerr

This unit is supplied with a multi-speed motor witha direct drive blower wheel which can obtainvarious air flows. The unit is shipped with factoryset cooling and heating speed taps. Airflowperformance tables are available for additionalspeed taps. Disconnect all power to the unit beforemaking any adjustments to the motor speed taps.Be sure to check the air flow and the temperature

drop across the evaporator coil to ensure sufficientair flow.

8. WWiirriinngg

Consult all schematic and pictorial wiring diagramsof this unit and the outdoor equipment todetermine compatibility of wiring connections andto determine specific requirements.

All field wiring to the air handler should be installedin accordance with the latest edition of the NationalElectric Code NFPA No. 70 and any local codes.Check rating plates on unit for rated volts,minimum circuit ampacity and maximum overcurrent protection. Supply circuit power wiringmust be 75 degree C (167 degree F) minimumcopper conductors only. Copper supply wires shallbe sized to the National Electric Code or local coderequirements, whichever is more stringent.

The unit is shipped wired for 230/240 Volt AC 60 HZ1 Phase Operation. If the unit is to be operated at208 VAC 60HZ, follow the instructions on the indoorunit wiring diagram to change the low voltagetransformer to 208 VAC operation (Ensure unit isproperly grounded).

Class 2 low voltage control wiring should not be runin conduit with power wiring and must beseparated from power wiring unless class 1 wirewith proper voltage rating is used.

Low voltage control wiring should be 18 Awg, colorcoded (105 degree C minimum). For lengths longerthan 100ft., 16 Awg wire should be used. Makecertain that separation of control wiring and powerwiring has been maintained.

9. AAiirr FFiilltteerr

To protect the coil, blower and other internal partsfrom excessive dirt and dust an air filter must beinstalled before air enters the evaporator coil. Aremote filter must be installed. Consult the filtermanufacturer for proper sizing and maximumvelocity requirements.

10. TThheerrmmoossttaatt

Select a thermostat that is commonly used with HPor AC single stage heating/cooling with electricheat. The thermostat will energize the fan on ademand for heat or cool.

Install the thermostat on an inside wall, away fromdrafts, lights or other heat sources in a location thathas sufficient air circulation from other rooms beingcontrolled by the thermostat.
