Wiring
All electrical connections and routing must comply with local and national codes. Do not
modify the factory installed wiring without written factory approval. The field wiring must
enter through the knockouts provided. Refer to the nameplate on the condensing or
evaporator coil to determine the proper electrical power supply. Wire type should be of
copper conductor only and properly sized to handle the electrical load. The unit and coil
must be properly grounded. Condensing unit wiring diagrams are attached inside the
electrical box cover. Evaporator coil wiring diagrams are located inside the installation
folder. Copies of the wiring diagrams are also available in the back of this manual.
WARNING
All wiring must comply with local and national codes. Wiring must be performed only by
a refrigeration technician or certified electrician. Failure to follow these guidelines may
result in injury!
CAUTION
Check all wiring connections, including factory terminals, before operation. Connections
can become loose during shipment and installation.
Piping
General Requirements:
All refrigeration piping and components are to be installed in accordance with applicable
local and national codes and in conformance with industry refrigeration guidelines to
ensure proper operation of the refrigeration system. Only refrigeration grade copper
tubing should be used. Long radius elbows should be used. Short radius elbows have
points of excessive stress concentration and are subject to breaking at these points, do
not use short radius elbows. Suction lines must be insulated with a minimum ¾” thick
armaflex to reduce heat pick-up.
