GENERAL

These heat pump units are designed for outdoor installation on

a roof or at ground level. Every unit is completely piped and

wired at the factory and is shipped ready for immediate installa-

tion. Only the liquid and vapor lines to the indoor coil, the con-

trol wiring and the main power wiring are required to complete

the installation. Each unit is dehydrated, evacuated, leak

tested and pressure tested at 450 psig before being pressur-

ized with a holding charge of Refrigerant-22 for shipment

and/or storage.

Every unit includes a heavy-duty compressor with line break

overload protection, a suction line accumulator, a 4-way re-

versing valve, a filter-drier, an expansion valve, a distributor, a

check valve, and a copper tube/aluminum fin coil.

All controls are readily accessible for maintenance, adjustment

and service. All power and control wiring can be routed through

the front of the unit.
