INSTRUCTION
GENERAL
These condensing 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 suction lines to the evaporator coil, the
control wiring and the main power wiring are required to com-
plete 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.
All controls are located in the front of the unit and are readily ac-
cessible for maintenance, adjustment and service. All wiring
(power and control) can be made through the front of 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 installer that personal injury
and/or equipment damage may result if installation procedure is not handled properly.
