General
These installation instructions are intended as a general
guide only, for use by an experienced, qualified contractor.
The 15GCSX units are single−package air conditioners
with two−stage gas heat designed for outdoor installation
on a rooftop or a slab.
The unit must be sized based on heat loss and heat gain
calculations made according to the methods of the Air
Conditioning Contractors of America (ACCA).
The units are shipped assembled. All piping, refrigerant
charge, and electrical wiring are factory−installed and
tested. The units require electric power, gas piping,
condensate drain and duct connections at the point of
installation. In addition, the heating vent hood must be
installed before the unit is placed into operation
