Electrical Wiring
NOTE: Field wiring must comply with the National Electric
Code (CEC in Canada) and any local ordinance that
may apply.
Electrical Power
It is important that proper electrical power is available at the
unit. Voltage must not vary more than 10% from that stamped
on the rating plate. (See Table 6 on page 9
maximum voltage.) Interphase voltage variation on three-phase
units must not be more than 3%. Contact local power company
for correction of improper voltage or phase unbalance.
Important: Models equipped with scroll compressors must
be phased correctly for proper compressor rotation. If the
compressor is noisy or if suction and discharge pressures
do not appear normal, reverse any two power leads to the
unit. Extended run time in reverse rotation will damage the
compressor and lead to premature failure.
Power Wiring
Power wiring should be run in grounded rain-tight conduit. See
Table 6 for wire ampacity and proper wire size.
Wire Routing
POWER WIRING MUST BE RUN IN CONDUIT. Conduit must
be run through the connector panel below the service cover
and attached to the bottom of the control box.
If low (extra-low in Canada) voltage control wire is run in
conduit with power supply, Class I insulation is required. If run
separate, Class II is required. Low voltage wiring may be run
through the insulated bushing provided in the 7/8" hole in the
connector panel, then route to the control box.
After completing wiring, check all electrical connections, including factory wiring
within the unit. Make sure all connections are tight. eplace and secure all electrical
box covers and access doors before leaving the unit or turning on power to the unit.
Failure to do so can cause a fire or electrical shock resulting in property damage,
personal injury or death.
