GENERAL

These outdoor units are designed to be connected to a match-
ing UPG indoor coil with sweat connection lines. These units
are factory charged with refrigerant for a matching indoor coil
plus 15 feet of field supplied  line. The outside unit is designed
to be placed alongside or at the back of the home, remote from
the indoor coil. The outdoor unit has been factory run-tested
and all components of the system are ready for easy, immediate
installation.

INSPECTION

Check the unit thoroughly for shipping damage. Unusually
rough handling during shipment may loosen blowers, fan
motors, compressors, or other components. Be sure that the
unit is ready to operate before installing it. If there is damage,
file a claim with the shipper. See Form 50.15-NM for more
information.

REFERENCE

Use this instruction in conjunction with the instructions for the
appropriate indoor unit, air moving system and accessories.

Installer should pay particular attention to the words NOTE,
CAUTION and WARNING.

NOTES are intended to clarify or make the installation easier.

CAUTIONS identify procedures which, if not followed carefully,
could result in personal injury, property damage or product
damage.

WARNINGS are given to alert the installer that severe personal
injury, death or equipment damage may result if installation
procedures are not followed properly.

NOMENCLATURE

LIMITATIONS

Caution:

The manufacturer is not responsible for the per-
formance of a mismatched system. The outdoor
unit must be installed with a compatible indoor unit
as designated in the specification data or in the
Directory of Certified Unitary Air Conditioners pub-
lished by the Air Conditioning and Refrigeration
Institute. Using unmatched components 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. Allowing
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 provides maximum performance
with minimum service.
