SPECIAL PRECAUTIONS
WARNING
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED 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.
• DO NOT use an adapter Plug or extension cord.
• DO NOT use a damaged power cord, plug, or wall outlet.
Replace them immediately.
• DO NOT change the internal wiring or any part of the

and unplugging. Use the Operation switch.
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 Installing
Place of Installation
• If possible, install the unit in a shady location. If the site
is exposed to the sun, you should provide a sun screen
as shown in Fig. a.
• Install it at a spot where optimum cooling circulation can
be obtained. No chairs or other obstructions are allowed
in front of the air conditioner.
• The back of the air conditioner must extend outside.
(Be sure the right and left intake vents are not obstructed
by walls or windows.)
• Keep enough space from any outside obstruction (wall,
bush, etc.).
• To provide water drainage, the unit must be tilted at a
downward angle 0.5 to 1 cm to the outside.

• While installing the air conditioner, be sure to loosen the
compressor locking nuts to avoid abnormal noise and
vibration. (NOTE: Locking nuts are not provided on some
models.)
• As a safety measure, it is recommended that two people
install the unit: one to hold and balance the unit — the
other to lower the window frame to secure the unit.
• Hold the unit securely, and be careful to not drop the
cabinet or any parts if the air conditioner is being
installed on an upper floor of a multistory building.
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 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 tools have been left inside
the unit being serviced.
Others
CAUTION
• 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.
