Replacing AN Existing UNIT?

Installation Instructions

Check the “Essential Elements” label for important information.

Use the correct wall case

This unit is designed to be installed in a GE plastic or insulated metal wall case. This minimizes condensation from forming on the room side of the case.

If the current wall case is not insulated, you can reduce the possibility of condensation forming by installing insulation kit RAK901L, available where you purchased the unit.

NOTE: There are several extra holes in the unit side flanges for installation in wall cases other than GE. To avoid damaging the flange insulation, the installer should use an awl or other sharp tool to puncture the insulation in the appropriate holes before installing the attachment screws.

Use the correct outdoor grille

You should use the outdoor grilles shown on the “Essential Elements” label on the top of the unit.

•If an existing grille is not replaced, capacity and efficiency will be reduced and the unit may fail to operate properly or fail prematurely. A deflector kit, RAK40, may be used with grilles that were not designed for your new GE Zonelines. The RAK40 contains air deflectors and gaskets that mount to the unit to direct the hot exhaust air away from the air intake to allow the unit to function properly. The grille must have a 65% minimum free area.

•Any vertical deflectors in the existing rear grille should be removed to decrease condenser air recirculation that can cause the unit to “short-cycle” and lead

to premature component failure.

Use the correct power cord

Local codes may require the use of arc fault or leakage current detection devices on 230/208-volt installations.

Replacing a ducted unit

New ducted installation:

If this unit is to be installed in a new ducted application using a duct adapter kit, the kit must be installed before the unit is placed in the wall case. The installation instructions are packed with the kit.
