GENERAL

These outdoor heat pump units are designed to be connected
to a matching UPG indoor coil with sweat connection lines. They
are equipped with a solid core filter-drier located in the dis-
charge line, a high pressure switch, a high temperature switch
(14 SEER models only). The units are factory charged with
refrigerant for a matching indoor coil plus 15 feet of field
supplied line. The outdoor unit is designed to be placed along-
side or at the back of the home, remote from the indoor coil.
The outdoor unit has been factory run-tested and all compo-
nents of the system are ready for easy, immediate installation.

LIMITATIONS

CAUTION: The manufacturer is not responsible for the
performance of a mismatched system. The out-
door unit must be installed with a compatible
indoor unit as designated in the specification
data or in the Directory of Certified Unitary Heat
Pumps published by the Air Conditioning and
Refrigeration Institute. Using unmatched com-
ponents may not only affect the performance of
the system, but may also void the warranty of
the equipment.
Do not install any coil in a furnace which is to
be operated during the heating season without
attaching the refrigerant lines to the coil. Allow-
ing the coil charge to enter the refrigerant lines
prevents excessive refrigerant pressure build-
up and possible coil damage.
The unit should be installed in accordance with all national and
local codes and regulations which govern the installation of this
type of equipment. In lieu of local codes, the equipment should
be installed in accordance with the National Electric Code, and
in accordance with the recommendations made by the National
Board of Fire Underwriters.
Limitations for the indoor unit, coil and appropriate accessories
must also be observed.
The outdoor unit must not be installed with any duct work in the air
stream. The outdoor fan is the propeller type and is not designed
to operate against any additional external static pressure.
The maximum and minimum conditions for operation must be
observed to assure a system that will give maximum perform-
ance with minimum service.
