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 instal-
lation. Only the liquid and suction lines to the evaporator coil,
the filter drier, the control 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

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.
