POWER CORD SELECTION GUIDE
HEAT PUMP MODELS
GA PTACs are not individually equipped with a power cord, so one must be ordered separately based on the voltage and
amperage of your electrical circuit. If the unit is to be plugged into a receptacle, then a line cord connection kit needs to be
selected. If it will be permanently connected, a hardwire connection must be used.

APPLICATION CONSIDERATIONS
Installation instructions are shipped with all PTAC
units. It is important that air conditioning systems be
properly sized and installed for each application in
order to achieve the desired temperature and humidity
levels within the space to be conditioned. It is
strongly recommended that a professional engineer
match the PTAC units with the building structure and
climate.
The following application considerations are all
important in choosing the proper PTAC system for
the building structure.
Undersizing
If a PTAC unit is undersized (cooling capacity is less
than required load for an application), the unit
will not be able to cool the space down to the desired
temperature during very hot days. The result could be
warm and humid or warm and dry conditioned space.
Oversizing
If a PTAC unit is oversized (cooling capacity is
greater than required load for the specific application),
the unit will cool the space down to the desired
desired temperature too quickly.
The unit will cycle on and off, however,
dehumidification only takes place when the unit is
operating. The result of this type of application in a
hot and/or humid climate would be a cool, yet
excessively humid, space.
Air Infiltration
Excessive air infiltration can intensify problems
associated with undersizing or oversizing a PTAC
unit. This can be the cause of insufficient cooling,
dehumidification, or heating. Sources of air
infiltration include vents, gaps around windows and
doors, and improperly sealed floors, ceilings or wall
joints.
GA
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
water passes though the suction port and is sprayed
on the warm outdoor coil for evaporation. Thus
providing better disposal of excess condensate and
improving unit operating efficiency.
It is normal and desirable to have some condensate
water in the ebase pan to boost operating efficiency.
NOTE: This unit will not always evaporate 100%
of the unit generated condensate and blown in
rain water. If it is necessary to control 100% of
the condensate, the Drain Kit (Part No.: DRAIN-
KIT-4PK) and a building condensate drain
system is recommended.
