7. MAKING ELECTRICAL
CONNECTIONS
WARNmNG:
Turn off all emectricam power at the
main circuit box before wiring
electrical power to the outdoor unit.
Failure to comply may cause severe
personal injury or death.
Wiring Diagram/Schematic -- 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.
Outdoor Unit Connections -- The outdoor
unit requires both power and control circuit
electrical connections. Refer to the unit wiring
diagram/'schematic for identification and location
of outdoor unit field wiring interfaces.
Control Circuit Wiring -- The outdoor unit is
designed to operate from a 24 VAC control
circuit. Control circuit wiring must comply with
the current provisions of the "National Electrical
Code" (ANSI CI.) and with applicable local
codes having jurisdiction.
Thermostat Connections -- Thermostat
connections should be made in accordance
with the instructions supplied with the thermostat
and with the instructions supplied with the
indoor equipment.
Electrica! Wiring -- Electrical wiring must
comply with the current provisions of the
"National Electrical Code" (ANSI CI.) and
with applicable local codes having jurisdiction.
Use of rain tight conduit is recommended.
Electrical conductors shall have a minimum
circuit ampacity in compliance with the
outdoor unit rating label. The facility shall
employ electrical circuit protection at a
current rating no greater than that indicated
on the outdoor unit rating label.
Disconnect Switch -- An electrically
compatible disconnect switch must be within
line of sight of the outdoor unit. This switch shall
be capable of electrically de-energizing the
outdoor unit.
Optional Equipment -- Optional equipment
requiring connection to the power or control
circuits shall be wired in strict accordance with
current provisions of the "National Electrical
Code" (ANSI C1.), with applicable local codes
having jurisdiction, and the Installation
Instructions provided with the equipment.
Optional Equipment (i.e., liquid line solenoid
valves, hard start kits, low suction pressure
cutout switch kit, high pressure cutout switch
kit, refrigerant compressor crankcase heater,
etc.) should be installed in strict accordance
with the manufacturer's Installation Instructions.
