Converting to Right Hand Return

One of the unique features of your NorthStar Series Heat Pump is the ability to quickly and easily convert the

unit from the factory-shipped left-hand return air configuration to a configuration where return air enters the

unit from the right-hand side. This is accomplished by moving the access doors and EZGEO control box from

the front of the cabinet to the rear of the cabinet and rotating the heat pump 180

°.

1. First, make certain that power is disconnected from the heat pump and remove the front, rear, and side

panels opposite of the air coil and filter.

2. Disconnect the two blower motor wire harnesses at the blower motor.

3. Using a Phillips screwdriver, remove the control box and hinged access doors. The attached wiring

harnesses are sufficiently long enough to allow for the relocation of the control box and door without

rewiring these components. Be sure the refrigerant manifold distribution lines do not rest against the u-

bends of the coil or the relocated control box.

4. Relocate and secure the control box and doors on the opposite side of the cabinet.

5. If you are not installing electric strip heat reattach the blower motor cables, front, rear and side panels. Your

Northern Heat Pump has now been converted to right-hand return.

6. If you are installing an optional Auxiliary Electric Heat unit (model KN-XX-X) observe the steps below.

Step #1 Remove (4) blower retaining screws and the retaining bracket keeping the blower from sliding.

Remove blower assembly from the cabinet.

Step #2 Remove the electrical box and heating element/s from the electric heater’s plenum. See

Auxiliary Strip Heat Installation Instructions.

Step #3 Invert the heater’s electrical box and reinstall in the heater’s plenum. This will keep the strip

heat elements in the blower’s air stream.

Step #4 Install the electric strip heater to the blower with the electrical box opposite the blower motor,

and secure assembly with sheet metal screws through the holes provided.

Step #5 Install the electric strip heat/ blower assembly from the new back of the cabinet, securing the

assembly to the cabinet with the screws removed during blower removal.

Step #6 Finish the installation as described in the electric strip heat installation instructions.

Step #7 Route and secure the electric strip heat low voltage control wires so they do not come in

contact with the refrigerant manifold distribution line.

7. Reattach the blower motor cables, front, rear and side panels. Your Northern Heat Pump has now been

converted to right-hand return.
