INSTALLATION INSTRUCTION
GENERAL
The outdoor units are completely piped and wired at the fac-
tory and are shipped ready for immediate installation. Only
the interconnecting liquid and suction lines, sight glasses,
control wiring, and the main power wiring are required to
complete the installation. Every unit is dehydrated, evacu-
ated, leak tested and pressure tested at 450 psig before be-
ing pressurized with a holding charge of refrigerant-22 for
shipment and/or storage.
To eliminate the costly cabinet deterioration problems usually
associated with outdoor equipment, all sheet metal parts are
constructed of commercial grade (G90) galvanized steel. Af-
ter fabrication, each part is thoroughly cleaned to remove
any grease or dirt from its surfaces. The parts that will be
exposed to the weather are then coated with a "desert sand"
powder paint to assure a quality finish for many years. This
coating system has passed the 750-hour, salt spray test per
Every unit includes 2 heavy-duty scroll compressors, 2 suc-
tion line accumulators, 2 4-way reversing valves with a 24
volt solenoid, 2 outdoor fan motors with inherent protection,
and a copper tube/aluminum fin coil that is positioned verti-
cally for better drainage of the water that will condense on it
during the heating cycle.
They also include 2 filter driers, 2 expansion valves and dis-
tributors that are only used during the heating cycle plus a
check valve to provide the proper flow of refrigerant through
the unit during both the cooling and heating cycles.
Installer should pay particular attention to the words: NOTE, CAUTION and WARNING. Notes are intended to clarify or make
installation easier. Cautions are given to prevent equipment damage. Warnings are given to alert installer that personal
injury and/or equipment damage may result if installation procedure is not handled properly.

INSPECTION
As soon as a unit is received, it should be inspected for pos-
sible 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.
