IImmppoorrttaanntt:: The low voltage wire harness is shipped in

the supplied document pack.

NNoottee:: The manufacturer recommends installing ONLY

A.H.R.I. approved, matched indoor and outdoor

systems. Some of the benefits of installing

approved matched indoor and outdoor split

systems are maximum efficiency, optimum

performance, and the best overall system

reliability.

NNoottee:: Condensation may occur on the surface of the air

handler when installed in unconditioned spaces,

verify that all electrical and refrigerant line

penetrations on the air handler are sealed

completely.

The TAMX air handlers will only use the following

internal electric heaters:

BAYEAAC04BK1 BAYEAAC10LG1

BAYEAAC04LG1 BAYEAAC10LG3

BAYEAAC05BK1 BAYEABC15BK1

BAYEAAC05LG1 BAYEABC15LG3

BAYEAAC08BK1 BAYEABC20BK1

BAYEAAC08LG1 BAYEACC25BK1

BAYEAAC10BK1

NNoottee:: Duct heaters cannot be applied with this air

handler.

NNoottee:: The heater size will be automatically configured

by installing a resistor in the Electric heat

harness located in the electric heat compartment

and will be included with the BAYEA heater.

Unit Design

able 1. Cabinet Penetration

Important: Due to the unique design of this unit, which allows the

electrical wiring to be routed within the insulation, do not

screw, cut, or otherwise puncture the unit cabinet in any

location other than the ones illustrated.

Important: Under no conditions should metal strapping be attached

to the unit to be used as support mechanisms for

carrying or suspension purposes.

Screws can be drilled

into bottom of unit.

(1/2” max. screw

length)

(Typical all sides)

Screws, saw cuts,

and other penetra-

tions are allowed in

the blower section

for installation of

Side Return Kit.

(Typical both sides)

Screws are allowed up to 3- 3/4”

from the top of the cabinet

(heater compartment).

(Typical both sides)

Screws for flange kit

attachment are allowed

along the interior of

thecabinet (see arrows)

(Typical all sides)

No penetrations

allowed.

(Typical all sides)

Screws allowed only

in the first 3/4” of front

bottom of unit (in

cross member)

able 2. Panel Removal

The unit contains four (4) access panels: Blower/Filter, Coil, Line Set,

and Heater.

The Blower/Filter panel is removed using 1/4 turn thumb screws.

1. Turn thumb screws on Blower/Filter panel.

2. Pull top of panel out, away from cabinet.

3. Lift panel up out of channel.

4. Set aside.

618-GJ89D1-1D-EN

The Coil, Line Set, and Heater panels are removed using Phillips head

screws.

Removal requires #3 Size Phillips

Coil and Heater panels must be removed prior to removing the Line

Set panel.

To remove Coil Panel:

1. Turn screws on Coil panel.

2. Rotate bottom of panel away from cabinet.

3. Remove panel from channel.

4. Set aside.

To remove Heater Panel:

1. Turn screws on Heater panel.

2. Pull panel straight out, away from cabinet.

3. Set aside.

Removal of the Line Set panel is required for all refrigerant line brazing

and some condensate line assembly depending on your orientation.

To remove Line Set panel:

1. Remove both Heater and Coil panels.

2. Turn screws on Line Set panel.

3. Pull panel straight out, away from cabinet.

4. Set aside.

Note: After replacing all panels, loosen the Line Set panel screws

approximately 1/4 — 1/2 turn. This will improve the seal

between the Heater Panel and Line Set panel.

Unit Install Preparation

1. Check for damage and report promptly to the carrier any damage

found to the unit.

Note: If the unit must be transported in a horizontal position, it must

be laid on its back (marked “REAR” on carton).

Note: After unit is removed from the carton, verify coil is pressurized.

Carefully remove the liquid line plug. If no pressure is released,

check for leaks.

Note: Remove the cardboard from the bottom of the blower. Cut the

tie wrap and remove the foam shipping block located at the

motor.

Note: Remove the ANA foam found between the blower and

evaporator coil.

Optional Cabinet Disassembly

Note: If the unit must be transported in a horizontal position, it must be

laid on its back (marked “REAR” on carton).

Note: To reassemble cabinet, follow the steps in reverse order. Ensure

electrical connections are secure and the plug clips are engaged.

1. Remove all four front panels.

2. Remove the two screws on the seal bar and pull the seal bar

straight out.

3. Disconnect all wiring connections routed to the blower assembly.

a. Disconnect the air pressure hose.

Note: Remove the cardboard from the bottom of the blower. Cut the

tie wrap and remove the foam block located at the motor.

Note: Remove ANA Foam from under the upflow drainpan.

ANA Foam

4. Slide Blower assembly out of unit using built-in blower support

channels and set aside.

5. Disconnect wires to the EEV motor and sensors. Cut the wire ties on

those wire harnesses if necessary and replace after re-installing.

Note: If cut, wire ties that held the sensor must be replaced after the coil is

placed back into the cabinet.

10 18-GJ89D1-1D-EN

6. Slide Coil assembly out of unit using built-in coil support channels

and set aside
