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.

Matching evaporators contain an orifice liquid feed sized for
the most common usage. The orifice size and/or refrigerant
charge may need to be changed for some indoor-outdoor unit
combinations, elevation differences or total line lengths.

SAFETY

Use this instruction in conjunction with the instruction for the
appropriate indoor evaporator coil, variable speed air handler
or furnace and other accessories. Read all instructions before
installing the unit.

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

NOTES are intended to clarify or make the installation easier.

CAUTIONS are given to prevent equipment damage.

WARNINGS are given to alert the installer that personal
injury and/or equipment damage may result if installation pro-
cedures  are  not  handled  properly..

INSPECTION

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. See Form 50.15-NM for more information.

LIMITATIONS

The unit should be installed in accordance with all national
and local safety codes and the limitations listed below:

1.

Limitations for the indoor unit, coil and appropriate
accessories must also be observed.

2.

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.

3.

The unit should not be operated at outdoor temperatures
below 45 °F. 

4.

Indoor evaporator coil orifice 

must be removed prior to

the installation of a TXV kit if the system match requires
a TXV.

 This product must be installed in strict compliance
with the enclosed installation instructions and any
applicable local, state, and national codes including,
but not limited to, building, electrical, and mechanical
codes.

Incorrect installation may create a condition where the
operation of the product could cause personal injury
or property damage.
