Installation Instructions REPLACING AN EXISTING UNIT? Checkthe "Essential Elements"labelfor importantinformation. Use the correct wall case This unit is designed to be installed in u GEplastic 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 base pan. • 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 GEZonelines.The RAK40contains 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 isto 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. Duct kits available: RAK6052 RAK601/602 Existing ducted installation: Replacement of an existing ducted unit may require different components. Requestthis information from your sales representative. • Replacing 230/208 volt units: See page 13. • Replacing 265 volt units: See page 14. When using a duct kit, you must always turn Mode 7 to ON "Ira ." See Mode instructions on page 7. DuctMode ShownON 12
