Lower Operating Costs and Reliable Comfort
for The Occupant
•
Heat pump models offer substantial savings
over models with conventional electric
resistance heaters
•
Individual units allow tenants to choose the
degree of comfort and operating economy.
•
Rapid servicing reduces downtime: complete
chassis can be replaced in minutes without
disrupting other occupants.
•
Each unit operates independently of other
units in the building. No dependency by
building on central HVAC system.
Terminal Connector Removal and Replacement
RETROFIT/REPLACEMENT
If you are replacing a unit in an existing wall sleeve,
your options include:
•
Replace the existing wall sleeve with the
the polymer wall sleeve. See accessory sleeve
section for selecting the correct sleeve for
your application.
NOTE: in most cases, when replacing the
wall sleeve, the exterior grille must also be
replaced.
•
Use an existing sleeve and exterior grille. The
Gree GA series PTAC will fit into:
The following major competitors' wall
—

be routed behind the front panel to the easily accessible terminal
connector.
