FIELD--INSTALLED ACCESSORIES (CONT.)
Condensate Drain Kit
Part No.: DRAIN--KIT--4PK
The drain kit may be attached to the exterior right or
left side of the wall sleeve for external draining or
mounted to the room side of the wall sleeve for
internal draining.
A 6 in. (152.4 mm) straight tube and 90
˚
curved tube
are supplied to simplify any application (1/2 in. /
12.7 mm OD copper).
IMPORTANT: For internal drains installed
in the plastic wall sleeve, the drain must be
installed on the flat area of the sleeve. It
cannot be installed in the wafer area.

Drain Kit
Replacement Filters
Part No.: GA-FILTER-10PK
The Gree GA model replacement air filters come
in packages of 10. The filters save energy by
preventing the evaporator coils from being plugged
with dirt and lint. These economical and sturdy filters
are interchangeable and may be washed, vacuumed,
and reused.

Baffle Kit
Part No.: BAFFLE--KIT--1PK
A07275
Baffle Kit
GA
This universal drain kit may be used internally or
externally to route condensate to a drainage system. It
can be field-installed on any Gree wall sleeve.
Although Gree units are designed to dissipate all the
condensate generated during normal cooling, there
may be times when abnormal conditions cause more
condensate than the unit can dissipate. If condensate
that drips from the wall sleeve is objectionable, this
internal/external drain kit should be installed.
The accessory baffle kit ensures a good seal between
the unit and the exterior grille to prevent air recircula-
tion, which can cause system failure.
The accessory baffle kit is required for applications
where a Gree wall sleeve is used without a Gree autho-
rized exterior grille.

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.
