INSTALLATION 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 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
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.
REFERENCE
This instruction covers the installation and operation of the
basic condensing unit. For information on the installation and
operation of the evaporator blower units, refer to instruction
Form 550.23-N4Y.
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.
