• Electrical connections must be in compliance with
all applicable local codes and ordinances, and with
the current revision of the National Electric Code
(ANSI/NFPA 70).
• For Canadian installations, the electrical connections
and grounding shall comply with the current Canadian
Electrical Code (CSA C22.1 and/or local codes).
Pre-electrical checklist:
√ Verify that the voltage, frequency, and phase of the
supply source match the specifications on the unit rating
plate.
√ Verify that the service provided by the utility is sufficient
to handle the additional load imposed by this equipment.
refer to the unit wiring label for proper high and low
voltage wiring.
√ Verify factory wiring is in accordance with the unit wiring
diagram. See Figure 11, (page 16) . Inspect for loose
connections.
√ Phase balance on 3 phase units must always be checked.
See Unbalanced 3-Phase Supply Voltage section on
page 8 .
line voltage
• It is recommended that the line voltage to the unit be
supplied from a dedicated branch circuit containing the
correct fuse or circuit breaker for the unit.
• an electrical disconnect must be located within sight
of and readily accessible to the unit. This switch shall
be capable of electrically de-energizing the outdoor unit.
See unit data label for proper incoming field wiring. Any
other wiring methods must be acceptable to authority
having jurisdiction.
• The minimum size of electrical conductors and circuit
protection must be in compliance with information listed
on the outdoor unit data label.
• Use only copper wire for the line voltage power supply
to this unit. Use proper code agency listed conduit and
a conduit connector for connecting the supply wires to
the unit. See Table 2, (page 8) Use of rain tight conduit
is recommended.
• See the unit wiring label for proper high and low voltage
wiring. Make all electrical connections in accordance
with all applicable codes and ordinances.
• Overcurrent protection must be provided at the branch
circuit distribution panel and sized as shown on the unit
rating label and according to applicable local codes.
See the unit rating plate for maximum circuit ampacity
and maximum overcurrent protection limits.
• Check all factory wiring to the wiring diagrams. Verify
none of the connections loosened during shipping or
installation.
• A wiring diagram/schematic is located on the inside
cover of the electrical box of the outdoor unit. The
installer should become familiar with the wiring diagram/
schematic before making any electrical connections to
the outdoor unit. See Figure 11 .
• Provide power supply for the unit in accordance with
the unit wiring diagram, and the unit rating plate.
• Units are shipped from the factory wired for 240 volt
transformer operation. For 208V operation, remove the
electrical Wiring
