The Right Fit For Comfort
RC21 REPLACEMENT PTAC
INSTALLATION INSTRUCTIONS
1. Take unit out of packaging.
2. Slide unit into wall sleeve. If supply duct on cooling
chassis does not line up with supply vent on room
cabinet it is possible that factory instlled angle brackets
on the top and sides will have to be reversed. This will
allow approximately 1” in or out of the wall sleeve (
See
Figures A5 & B5).
2. Slide unit out of wallsleeve.
3. Remove baffles from kit bag supplied with unit.
IMPORTANT: The correct condenser air baffles must be
installed or performances may be impaired and/or the
war
ranty will be voided.
4. Baffle Installation - Install left and right side baffles on
the condenser coil in existing holes:
• Choose the proper fitting baffles for your application.
• Baffles must come in contact with the outdoor lou-
ver.
Make sure baffles are directed inward toward the
center of coil.
• Secure baffles tightly to the condenser coil using the
screws provided. (Figures A5, B5 & C5 )
5. Apply 1/2” x 1/2” open cell foam strips around supply
air duct to ensure that all the conditioned air is delivered
into the room. Failure to do so results in recirculation of
the conditioned air around the wall sleeve and through
the unit causing the unit to short cycle, thus raising
operating costs through improper heating and cooling
(Figure C5).
