Electrical Wiring
All wiring should be done in accordance with the
National Electrical Code, ANSI/NFPA No. 70 (latest
edition); Canadian Electrical Code Part 1, CSA C22.1
(latest edition); or local codes where they prevail. Use
wiring with a temperature limitation of 75°C minimum. Run
the 208 or 230 volt, 60 hertz electric power supply through
a fused disconnect switch to the connection box of the unit
and connect as shown in the wiring diagram located on
the inside of the control access panel.
Power supply to the unit must be N.E.C. Class 1, and must
comply with all applicable codes. A fused disconnect switch
should be field provided for the unit. The switch must be
separate from all other circuits. If any of the wire supplied
with the unit must be replaced, replacement wire must be of
the type shown on the wiring diagram. Electrical wiring must
be sized to carry minimum circuit ampacity marked on the
unit. Use copper conductors only. Each unit must be wired
with a separate branch circuit and be properly fused.
Thermostat
The room thermostat should be located on an inside wall
where it will not be subject to drafts, sun exposure, or heat
from electrical fixtures or appliances. Follow the
manufacturer's instructions enclosed with thermostat for
general installation procedure. Color-coded insulated wires
(#18 AWG) should be used to connect thermostat to unit.
Four wires are required for cooling. The heat anticipator
setting is 0.7 amp.
Compressor
Units are shipped with compressor mountings factory-
adjusted and ready for operation. Caution: Do not
loosen compressor mounting bolts.
