INSTALLATION INSTRUCTIONS

NOTE: KEEP INSTRUCTIONS READILY AVAILABLE.

A. DESCRIPTION OF AIR CONDITIONING CONDENSER

The outdoor condensing unit is designed and built with a totally enclosed (hermetic) scroll compressor
which offers the advantages of simplicity, quiet operation and reduced condenser size. The entire air
conditioning system has been built and performance tested against rigid standards. The installation must
comply with the National Electrical Code ANSI/NFPA 70-(latest edition), any state or local codes, and
these instructions.

B. LOCATION OF OUTDOOR CONDENSING UNIT

The primary consideration in selecting the location of the outdoor-condensing unit is how the location
affects the length of the refrigerant tubing lines. Bear in mind, that the longer the tubing line, the greater the
pressures drop causing a reduction in the cooling capacity of the unit.

Another consideration in the location selection is the sun load placed on the outdoor condensing unit.
Locations, which place the unit in direct exposure to the sun during the majority of a day, should be avoided
if possible. Inside corners on the southeast or southwest corners are to be avoided as the heat build-up in
such corners would place an increased workload on the unit. Shaded locations on the north side of a home or
office are generally best if practical.

Mount the unit on a sturdy base at least one inch above the ground. Be sure to use well-tamped gravel fill
beneath the blocks or bricks to prevent settling if concrete blocks or bricks are used. Use a minimum 4"x4"
"treated" timbers plus gravel fill to prevent settling if timbers are used.

:A premature compressor failure may result and will "VOID THE WARRANTY" if the

outdoor condensing unit is located in an enclosure such as a garage or not in accordance with these
instructions.

Please refer to the Peace of Mind Warranty Certificate included with this product for warranty
information.

All models feature an “up-flow” airflow design discharged through the top grill. For this reason, the outdoor
condensing unit should not be located under an overhang or any other construction, which would direct the
discharged air back to the outdoor condensing unit. The unit should be located as illustrated below.

C. TUBING INSTALLATION

The compressor oil is constantly pumped through the liquid line, evaporator coil, and back through the
suction line in normal operation of an Air Conditioning system. Please follow the guide lines listed below to
insure proper lubrication of the compressor by avoiding oil accumulation at undesirable points in the
system.

1. No traps in the suction line are necessary if the outdoor condensing unit is level with the indoor
evaporator coil or the indoor evaporator coil is 4 feet or less lower than the outdoor condensing unit. Any
horizontal runs of suction line should have minimum 1/2" pitch towards the outdoor condensing unit for
every 10 feet of line.

2. A trap is necessary in the suction line at the indoor evaporator coil if the indoor evaporator coil is more
than 4' below the outdoor condensing unit and 1 trap per every 10’ of vertical rise thereafter.

: A gradual loop in the tubing can be constructed to take up the excess tubing if you find that

too much tubing has been brought onto a job. Such a loop MUST be kept in a horizontal (flat) plane to
avoid trapping the oil. Refrigerant lines should be inserted into a suitable conduit or raceway when the lines
are to be buried between the building and the outdoor condensing unit. The lines must be provided with
sufficient protection and support to prevent damage when installed above the ground.

NOTES:
For line lengths over 25’ adjust charge accordingly per foot of variation from chart.

.
.65 oz. per foot for 3/8” and 3/4” line set
.674 oz. per foot for 3/8” and 7/8” line set
.694 oz. per foot for 1/2” and 7/8” line set
.72 oz. per foot for 1/2” and 1-1/8” line set
.76 oz. per foot for 5/8” and 1-1/8” line set

These charges are to be used in conjunction with a superheat measurement for best performance.

1. Tubing dimensions are outside diameter.

2. Tubing Type ACR, (Type K heavy wall or Type L medium thick wall)

3. Refrigerant line lengths over 100’ are not recommended.

4. These line size recommendations are based on the use of refrigeration grade tubing and do not
include considerations for additional pressure drops due to elbows, valves, or reduced joint sizes.
