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 TAM7 air handlers will only use the following internal electric heaters:

BAYEVAC04BK1AA BAYEVAC10LG1AA

BAYEVAC04LG1AA BAYEVBC15BK1AA

BAYEVAC05BK1AA BAYEVBC20BK1AA

BAYEVAC05LG1AA BAYEVCC25BK1AA

NNoottee:: Duct heaters cannot be applied with this air

handler.

Unit Design

Screws ca n be drilled into bottom of unit. (1/2” max. s crew length) (Typical all sides)

Screws , saw cuts, and other penetrations are a llowed in the blower se ction for low voltage wiring or installat

n of Side Return Kit. (Typical both sides)

Screws are a llowed up to 3- 3/4” from the top of the ca bine t (heate r compartment). (Typical both sides)

Screws for flange kit attachment are allowe

d along the inte rior of the cabinet (se e arrows ) (Typical all sides)

No penetrations allowe d. (Typical all sides)

Screws allowe d only in the first 3/4” of front bottom of unit (in cross member)

Table 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.

Table 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.

18-GJ06D2-2E-EN

UUnniitt DDeessiiggnn

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. Pull bottom of panel out, away from cabinet.

3. Pull panel down and out of 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.

18-GJ06D2-2E-EN

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.

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.

See Table 2, p. 5

4. Slide Blower assembly out of unit using built-in blower support channels and set aside.

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

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

5. Remove airflow diverter from the bottom of coil drain pan by gripping the plastic diverter while using your thumbs to spread the top of the diverter slightly outwards and then pulling down and out through the blower opening as illustrated.

6. 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.

7. Slide Coil assembly out of unit using built-in coil support channels and set aside

18-GJ06D2-2E-EN

8. Use a 5/16 Allen wrench on the locking mechanism on each side of the bottom half of the cabinet to loosen the locking mechanism. The locks loosen by turning counter-clockwise approximately 3/4 of a turn.

9. Lift the Coil section up and away from the Blower section. Set aside.

Note: When separating the two cabinet pieces, make sure the gasket

remains intact.

10. For extremely tight spaces where the cabinet needs to be rotated through a small opening, remove the top panel and all cross members. Use a manual driver to avoid stripping screw holes.

11. Continue preparation by following the proper carrying procedures shown in the next section.

18-GJ06D2-2E-EN

Placing Unit at Location

Cross M em bers

1. Carry the unit to the installation location

2. Reassembly by reversing the steps listed in Section 4 if disassembly was required. If cut, wire ties that held the sensor wiring must be replaced.

Important: Under no conditions should metal strapping be attached

Approved Carrying:

• Hold by the cross members within the cabinet or unit top plate and

to the unit to be used as support mechanisms for carrying or suspension purposes.

use as handles for lifting and carrying the coil and blower sections.
