 units are single package air conditioners

designed for outdoor installation on a rooftop or slab and for
non-residential use. These units can be equipped with factory
or field installed electric heaters for heating applications.

These units are completely assembled on rigid, permanently
attached base rails. All piping, refrigerant charge, and electri-
cal wiring is factory installed and tested. The units require
electric power and duct connections. The electric heaters
have nickel-chrome elements and utilize single-point power
connection.

Due to system pressure, moving parts, and electrical compo-
nents, installation and servicing of air conditioning equipment
can be hazardous. Only qualified, trained service personnel
should install, repair, or service this equipment. Untrained
personnel can perform basic maintenance functions of clean-
ing coils and filters and replacing filters.

Observe all precautions in the literature, labels, and tags
accompanying the equipment whenever working on air condi-
tioning equipment. Be sure to follow all other applicable
safety precautions and codes.

Wear safety glasses and work gloves. Use quenching cloth
and have a fire extinguisher available during brazing opera-
tions.

As soon as a unit is received, it should be inspected for possi-
ble damage during transit. If damage is evident, the extent of
the damage should be noted on the carrier’s freight bill. A
separate request for inspection by the carrier’s agent should
be made in writing.
