The Right Fit For Comfort
PREPARATION FOR INSTALLATION
IMPORTANT: RetroAire Dual Motor PTACs are to be used
with metal wallsleeves. The sleeves must employ front
panels secured by screws that prevent contact with all parts
with minor dimensions of openings not exceeding 1/2”. The
final assembly must employ an indoor air discharge grill
having dimensions not less than 26” x 4”, separating the top
surface of the chassis from the top surface of the discharge
grill by a minimum of 1”. For all models, the outdoor
openings must prevent contact of all moving parts by means
of louvers or grills with minor dimension not exceeding 1”.
All cord connected 265 Volt units must be plugged into
receptacles within the unit subbase or chassis.
1. Remove the front of the existing room enclosure. This
will expose the old chassis.
2. Disconnect the power supply. If a line cord and plug
were used, remove it from the receptacle. If the chassis
is hard wired, locate the circuit breaker, place it in the
“OFF” position, and tag it, announcing work is being
done. DO NOT TURN ON.
3. Loosen any tie down bolts or screws and remove the
old chassis.
IMPORTANT:
Dispose of old chassis per present state
and federal regulations.
4. Inspect the wall sleeve/cabinet for rust, holes, and dam
-
age. Clean the wall sleeve of any dirt, repair any damage,
and ensure proper drainage of condensate or rainwater
to exterior of building.
5. Remove or repair old weather seals and note location
for installation of any new seals.
6. Check the wall sleeve/cabinet to assure all drain holes
are open and that
(A) the unit is level left to right and (B)
the back is pitched to the outside by 1/2” maximum.
7. Check the present voltage to verify the new chassis is a
matching voltage and that the line cord and receptacle
match.
8. Before installing the new chassis, inspect the outdoor
louver for a minimum free area of 70% and remove
any obstructions. Any variation will restrict air flow over
the condenser coil and cause serious damage to the
chassis. It will also void the warranty.
The correct condenser air baffles must be properly
installed or performance will be impaired and/or the
warranty will be voided!!
See individual unit installation instructions for more
information.

cut or frayed wires. Replace such wiring if found.
2. Check the unit rating plate for circuit ampacity and
breaker or fuse size. Use only HACR type breakers
.
Select the proper wire for the ampacity rating.
3. If plug and receptacle are used, check the compatibility.
The chassis can be hard wired or direct connected as
well.
4. Each unit must have a separate branch ciruit protected
by a fuse or breaker. Refer to the unit rating plate for the
proper wire and breaker or fuse size. Use of extension
cords is prohibited.
To avoid possible injury or death due to electrical
shock, open the power supply disconnect switch
and secure it in an open position during installation.
On a plug and receptacle connection, keep the unit
unplugged until installation is complete.
