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

ASTM Standard B117.

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.

All controls are located in the front of the unit and are readily

accessible for maintenance, adjustment and service.  All wir-

ing (Power and Control) can be made through the front of

the unit.

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.

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.
