GENERAL INFORMATION
These outdoor heat pump units are designed to be con-
nected to a matching UPG indoor coil. They are equipped
with a solid core filter-drier located in the discharge line and a
high pressure switch. 14 SEER models are also equipped
with a high temperature switch. One of two types of connec-
tion lines are required, depending on the model:
•
Units with sweat-fit base valve connections are factory
charged with refrigerant for a matching UPG indoor coil,
plus 15 feet of field supplied line.
•
Units with quick-connect coupling connections are fac-
tory charged with refrigerant to be matched with the
appropriate pre-charged line set, and UPG indoor coil.
The outdoor unit is designed to be placed near the perimeter
of the home, typically alongside or at the back of the home,
remote from the indoor coil. The outdoor unit has been fac-
tory 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 fan motors, com-
pressors, 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.
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 care-
fully, could result in personal injury, property damage or
equipment damage.
WARNINGS
are given to alert the installer that severe per-
sonal injury, death or equipment damage may result if instal-
lation procedures are not followed properly.
LIMITATIONS
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 equip-
ment should be installed in accordance with 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 accesso-
ries 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 perfor-
mance with minimum service.
** Operation below this temperature is permissible for a
short period of time when required to bring the heating
area up to 50° F.
Check Electrical Power Supply
The electrical power should be checked to determine if ade-
quate power is available, and near constant voltage can be
maintained. If there is any question concerning the power
supply, contact the local power company for corrections; oth-
erwise, unsatisfactory performance may result.
Selecting the Best Heat Pump Location
Several important factors must be considered before select-
ing the site for the outdoor unit:
•
Distance to indoor coil
•
Proximity to the structure
•
Proximity to vents and exhaust systems
•
Ability to service
•
Sound transmission
•
Air circulation
•
Wind direction
•
Relationship between structure, sun, and unit
•
Distance from power source
•
Defrost drainage
•
Water drainage
•
Average winter snow depth
•
Local codes
The manufacturer is not responsible for the perfor-
mance of a mismatched system. The outdoor unit
must be installed with a compatible indoor unit as
designated in the specification data or in the Direc-
tory of Certified Unitary Heat Pumps published 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 attach-
ing the refrigerant lines to the coil. Allowing the coil
charge to enter the refrigerant lines prevents exces-
sive refrigerant pressure build-up and possible coil
damage.
