APPLICATION CONSIDERATIONS
Installation instructions are shipped with all PTAC
units. It is important that air conditioning systems be

Condensate Removal
Gree's GA series has a new condensate (water)
disposal system. The outdoor fan prop has a built in
slinger ring which draws condensate water through a
suction port built into the outdoor coil shroud. The
