Installation Instructions
1
The RAB71 or RAB77 wall
case must be properly installed
per instructions packed with
the case.
2
Remove the corrugated stiffener
and the outdoor protective
panel. Use the slit in the out-
door panel as a handhold and
push out.
3
Install the exterior grille from
the room side following instruc-
tions packed with the grille.
Insulated Wall Case
In some climates/applications
when the wall case projects into
the room, the use of an insulated
wall case will minimize moisture
condensed on the wall case
surfaces. The RAB71 wall case is
insulated. Insulation kit RAK901L
is available for use with RAB77 or
existing uninsulated wall cases
when needed.
