WARNING
• Before performing any electrical work, ensure
all power is off. Electrical shock may occur.
• All outdoor unit's capacitor's to discharge
otherwise electrical shock hazard may occur.
• Ensure the unit is properly grounded.
ELECTRICAL WIRING
AND SUPPLY VOLTAGE:
All electrical wiring must be done according to
local codes. Additionally installations in the USA,
must conform to the current National Electric Code
(NEC) and Installations in Canada must conform to
current Canadian Electric Code (CEC). Nameplate
data indicates the operating voltage, phase,
ampacity, maximum over current protection, and
minimum voltage.

The contractor is to provide an individual branch
circuit for over current protection for the unit as
required by code. Some codes may require a
disconnect between the indoor and outdoor unit.
Run power supply wiring through a weatherproof
disconnect box and conduit to the unit connection.
Disconnects are required to be within sight and
easy reach of the unit (usually within 3 feet).
Circuit breakers and disconnect switches should
be properly sized based on the required codes and
the unit's nameplate requirements. (Fig.12)
Check the unit wiring diagram for the number of
conductors required. Ensure that the proper AWG
(gauge) and type of wired is used to comply with
code and the unit's nameplate. Route neatly and
protect from sharp edges and damage.
Inadequate wiring and/or improper electrical
supply will likely result in failure of the compressor
and other electrical components and voids the
warranty.
