GENERAL INFORMATION
These outdoor units are designed to be connected to a
matching 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 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.
Check Electrical Power Supply
The electrical power should be checked to determined 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 Condensing Unit Location
Several important factors must be considered before select-
ing the best site for the air conditioning outside 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
•
Water drainage
•
Local codes
Locate the outside unit near enough to the indoor coil vicinity
to eliminate lengthy refrigerant line runs. Do not locate the
outside unit so it discharges air under eaves or gutters. Rain
or snow melt-off should not be able to run off a roof and down
upon the unit. Be sure vents are not located upwind from the
outside unit.
A minimum clearance of 18 inches is required for service at
the control panel and compressor compartments access. A
10 inch clearance is required for the air inlet to the outdoor
coil around the perimeter of the unit. The air discharge of the
unit requires a 60 inch clearance between the top of the unit
and any obstruction. See Figure 1.
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 Air Conditioners 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.
