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 installation. Only the liq-
uid 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, evacu-
ated, leak tested and pressure tested at 450 psig
before being pressurized 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 accessible for maintenance, adjustment and
service. All wiring (power and control) can be made
through the front of the unit.

SAFETY CONSIDERATIONS

The installer should pay particular attention to the
words:  NOTE,  CAUTION, and WARNING. Notes are
intended to clarify or make the installation easier. Cau-
tions are given to prevent equipment damage. Warn-
ings are given to alert installer that personal injury and/
or equipment damage may result if installation proce-
dure is not handled properly.
