ELECTRICAL CONNECTIONS
WARNING:
ELECTRICAL SHOCK, FIRE OR
EXPLOSION HAZARD
Failure to follow safety warnings exactly could
result in serious injury or property damage.
Improper servicing could result in dangerous
operation, serious injury, death or property
damage.
• Before servicing, disconnect all electrical power
to the indoor blower.
• When servicing controls, label all wires prior
to disconnecting. Reconnect wires correctly.
• Verify proper operation after servicing.
• 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 10 (page 18) , Figure 11 (page 19) ,
& Figure 12 (page 20) . Inspect for loose connections.
Line Voltage
• A wiring diagram is located on the inside cover of the electrical
box of the unit. The installer should become familiar with the
wiring diagram before making any electrical connections to
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.
• Line voltage to the unit should be supplied from a dedicated
branch circuit containing the correct fuse or circuit breaker for
the unit. Incoming field wiring and minimum size of electrical
conductors and circuit protection must be in compliance with
information listed on the unit data label. Any other wiring
methods must be acceptable to authority having jurisdiction.
• Provide power supply for the unit in accordance with the unit
wiring diagram, and the unit rating plate. Connect the line-
voltage leads to the terminals on the contactor inside the
control compartment. Extend leads through power wiring hole.
See Figure 7 . Connect L1 & L2 directly to the contactor.
• The unit requires both power and control circuit electrical
connections. Refer to the wiring diagrams Figure 10 (page
18) , Figure 11 (page 19) , & Figure 12 (page 20) for
identification and location of unit field wiring interfaces. Make
all electrical connections in accordance with all applicable
codes and ordinances.
• 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. Use of
rain tight conduit is recommended.
