The Right Fit For Comfort
INSTALLATION INSTRUCTIONS
1. Take unit out of packaging.
2. Slide unit into wall sleeve. The supply duct on the cool
-
ing chassis should line up with the supply vent on the
room cabinet. The weather angles should require no
adjustment.
3. Make sure baffles come in contact with the outdoor
louver.
IMPORTANT:
Baffles and open cellfoam tape seals
are factory installed on the RC
12 . Baffles fill the gap
between the rear of the chassis and the outdoor louver
and prevent the air from recirculating. Consult the factory
if baffles supplied are not deep enough to accommodate
wall sleeve application as system efficiency and reliability
are dependent on proper air flow. (
Figure A3)
IMPORTANT: If adjoining room conditioning is required, the
RC12 is able to discharge to the right and left by utilizing
the four-inch knockouts
(Figure B3) on either side of the
evaporator compartment using 4” flex duct.
3. Once confident that all seals are the correct size and in
the proper location and the correct baffles are attached
to the condenser coil and in the proper orientation, slide
unit into final position and tighten any tie down bolts or
screws as necessary.
