Installation Instructions
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.
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 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 (as calculated by ASHRAE).  
See the Architects and Engineers Data Manual for more 
detailed information.
•   Any vertical deflectors in a non GE 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.
Duct kits available:
RAK6053
RAK601B/602B
Existing ducted installation: 
Replacement of an existing ducted unit may require 
different components. Request this information from your 
sales representative. Duct seals on existing unit need to 
be removed and added to the new unit.
• Replacing 230/208 volt units: 
See page 16.
• Replacing 265 volt units: 
See page 17.
When using a duct kit, you must always turn Mode 7 to 
ON “   ” See Mode instructions on page 9.
