INSTALLATION INSTRUCTIONS
1. To test the alignment, slide the RC40 into the wall sleeve
until the supply duct is flush with the supply louver on
the room cabinet.
2. Slide unit out of wall sleeve.
3. Remove baffles from the kit bag supplied with unit.
Condenser baffles must be secured tightly to the
condenser coil and the baffles need to come in contact
with the outdoor louver. To install the baffles point both
baffles toward the center of the condenser and fasten
using the existing holes and screws provided. (
Figure 4)
4. ½” X ½” open cell polyfoam must be placed around the
supply air duct on top of the cooling chassis. Failure
to do so will result in re-circulation of the conditioned
air around the wall sleeve and through the unit, causing
the unit to short cycle.
(Figure 5 page 10)
5. 1” X 1” open cell polyfoam is provided to prevent outside
air from entering around the chassis to the room from
the sides and top of the cabinet. Install between well
sleeve and cooling chassis.

RC40 REPLACEMENT CHASSIS
The RetroAire RC40 is a cooling only replacement chassis
designed to upgrade room comfort through higher efficiency
and enhanced reliability.
The RetroAire RC40 uses a high-efficiency rotary compressor
protected under a 5-year warranty and an enhanced high-
efficiency heat exchanger to make the replacement of worn
out and inefficient units a very attractive option.
Whisper quiet operation improves the room ambience and
the 20 gauge G-90U galvanized steel construction of the
chassis ensures long service life.
The RetroAire RC40 9,000, 12,000 and 15,000 Btuh units
are all available in a 21" chassis.
*Depending on wall-sleeve
depth, the RC 15,000 Btuh may need deeper baffles in-
stalled for proper operation (baffles supplied in kit bag).
The 9,000 and 12,000 Btuh units are single motor applica-
tions, while the 15,000 Btuh unit is a dual-motor applica-
tion. All three capacities have two fan speeds and come
equipped with a fan cycle switch.
All three capacities come equipped with a fan cycle switch.
These units offer an optional motorized fresh air feature with
a positive pressure seal, and positive condensate re-
evaporation which improves efficiency.
