INSTALL THE WALL CASE AND
EXTERIOR GRILLE
The RAB71 series or RAB77 wall case must be
properly installed per instructions packed with
the case.
• Remove the corrugated stiffener and the outdoor
protective panel. Use the slit in the outdoor panel
as a handhold and push out.
• Install the exterior grille from the room side
following instructions packed with the grille.
Insulated Wall Case
This unit is designed to be installed in a GE plastic
or an insulated steel wall case. This minimizes
condensation from forming on the room side of
the case.
The RAB71 series wall cases are insulated. Insulation
kit RAK901L is available for use with RAB77 or
existing uninsulated wall cases when needed.
NOTE: For installation with a subbase or duct adapter,
see the instructions packed with those kits.
