SPECIAL PRECAUTIONS
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSON-
AL INJURY OR DEATH. ONLY A QUALIFIED, EXPERI-
ENCED ELECTRICIAN SHOULD ATTEMPT TO WIRE
THIS SYSTEM.
All wiring must conform to local electrical codes.
Each unit must be properly grounded with a ground (or
earth) wire or through the supply wiring.
DO NOT, under any circumstances, cut or remove the
third (ground) prong from the power cord plug.
Never use an extension cord with this air conditioner.
DO NOT use a damaged power cord, plug, or wall out-
let. Replace them immediately.
DO NOT change the internal wiring or any part of the
system.
DO NOT turn the air conditioner on and off by plugging
and unplugging. Use the Operation switch (SELEC-
TOR).
Follow National Electrical Code (NEC) and local codes,
ordinances and regulations. All wiring — including
installation of receptacles, must be in accordance with
these codes.
The NEC requires permanent connection for installa-
tions over 250 volts.
Protective devices (fuses or circuit breakers) accept-
able for this air conditioner are specified on the name-
plate of each unit.
Aluminum building wiring may pose special problems
— consult a qualified electrician.
When Transporting
Be careful when picking up and moving the air conditioner.
Get a partner to help, and bend your knees when lifting to
reduce strain on your back. Sharp edges or thin aluminum
fins on the air conditioner can cut your fingers.
When Servicing
Turn the power OFF at the main power box (mains)
before opening the unit to check or repair electrical
parts and wiring.
Keep your fingers and clothing away from any moving parts.
Clean up the site after you finish, remembering to
check that no metal scraps or bits of wiring have been
left inside the unit being serviced.
Tools Needed
Phillips screwdriver
Flat blade screwdriver
Others
Before starting the installation, the power to the direct
connect wiring should be set to OFF.
Ventilate any enclosed areas when installing or testing the
refrigeration system. Escaped refrigerant gas, on contact
with fire or heat, can produce dangerously toxic gas.
Confirm upon completing installation that no refrigerant
gas is leaking. If escaped gas comes in contact with a
stove, gas water heater, electric room heater or other
heat source, it can produce dangerously toxic gas.
