The Right Fit For Comfort
The RetroAire Dual Motor PTAC is available in nominal
sizes of 9,000 Btuh, 12,000 Btuh, 15,000 Btuh, and 18,000
Btuh.* With energy efficiency ratings as high as 10, the
replacement of worn out and inefficient units is a very at-
tractive option.
* The RC12 PTAC, however, is only available in nominal
sizes of 12,000 Btuh and 15,000 Btuh.
All Retroaire products are backed by Enviromaster
International LLC and are rated in accordance with ARI
Standards 310 and 380 and UL Standard 484.
PRE-INSTALLATION
Test run the Dual Motor PTAC prior to installation. Connect
the line cord to a proper power supply (such as the one the
old unit is plugged into) and check all controls for proper
operation. Disconnect the chassis before installing.
Review baffle and foam tape installation to ensure proper
air seal and unit operation.
THE DUAL MOTOR PTAC FAMILY
The RetroAire Dual Motor PTAC is available as a cooling-
only model or, for those who wish to up-grade to a heat
pump, the RH10, 20, 35, 45, 80, and 90 heat pump chassis
will fit the existing wall sleeve. The heat pump version will
reduce energy costs during periods of outdoor temperature
ranging down to as low as 40° F.
The Dual Motor PTAC uses a high-efficiency rotary com-
pressor 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.
The RetroAire Dual Motor PTAC offers two fan speeds
– three in the RC12 – and has an optional motorized fresh
air feature with a positive pressure seal, override switch, and
positive condensate re-evaporation to improve efficiency.
Whisper quiet operation improves the room ambience and
the 20 gauge galvanized steel construction of the chassis
ensures long service life.
