POWER CORD PROTECTION FOR

230/208V UNITS

The power cord for the 208/230--v unit provides

power cord protection by automatically

disconnecting power during an unsafe condition.

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

ordertoachievethedesiredtemperatureandhumidity

levels within the space to be conditioned. It is

strongly recommended that a professional engineer

match thePTAC unitswiththebuilding structureand

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 spac

e down to the desired

temperatureduringveryhotdays. Theresult couldbe

warm and humidor warm and dry conditionedspace.

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 beacool, yet

excessively humid, space.

Air Infiltration

Excessive air infiltration can intensify problems

associated with undersizing or oversizing a PTAC

unit. This can be the ca

use 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.

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.
