(ANSI/NFPA 70).
• ForCanadianinstallationstheelectricalconnections
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 (Figures 8 - 10, pages 19 - 21). Inspect for
loose connections.

• Itisrecommendedthatthelinevoltagetotheunitbe
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 unit wiring diagram, and the unit rating plate.
• Connecttheline-voltageleadstotheterminalsonthe
contactor inside the control compartment. Extend leads
through power wiring hole (Figure 6). Connect L1 & L2
directly to the contactor.
• Useonlycopperwireforthelinevoltagepowersupply
to this unit as listed in Table 1. 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.
• Seetheunitwiringlabelforproperhighandlowvoltage
wiring. Make all electrical connections in accordance
with all applicable codes and ordinances. See Figures
