Explanations given to user
• Upon completion of the installation work, tell the user where the
circuit breaker is located. If the user does not know where the
circuit breaker is, he or she will not be able to turn it off in the
event that trouble has occurred in the air conditioner.
• If the fan grille is damaged, do not approach the outdoor unit
but set the circuit breaker to the OFF position, and contact
a qualif ed service person to have the repairs done. Do not
set the circuit breaker to the ON position until the repairs are
completed.
• After the installation work, follow the Owner's Manual to explain
to the customer how to use and maintain the unit.
Relocation
• Only a qualified installer or qualified service person is allowed
to relocate the air conditioner. It is dangerous for the air
conditioner to be relocated by an unqualif ed individual since a
fire, electric shocks, injury, water leakage, noise and/or vibration
may result.
• When carrying out the pump-down work shut down the
compressor before disconnecting the refrigerant pipe.
Disconnecting the refrigerant pipe with the service valve left
open and the compressor still operating will cause air or other
gas to be sucked in, raising the pressure inside the refrigeration
cycle to an abnormally high level, and possibly resulting in
rupture, injury or other trouble.

CAUTION
New refrigerant air conditioner installation
• This Air Conditioner uses R410A an environtally friendly
refrigerant.
• The characteristics of R410A refrigerant are; easy to absorb water,
oxidizing membrane or oil. Accompanied with the new refrigerant,
refrigerating oil has also been changed. Therefore, do not let
water, dust, former refrigerant, or refrigerating oil enter the
refrigerating cycle during installation work.
• To prevent charging an incorrect refrigerant and refrigerating oil,
the sizes of connecting sections of charging port of the main unit
and installation tools are changed from those for the conventional
refrigerant.
• Accordingly the exclusive tools are required for the new
refrigerant (R410A).
• For connecting pipes, use new and clean piping designed for
R410A, and please care so that water or dust does not enter.
To disconnect the appliance from main power supply.
• This appliance must be connected to the main power supply by
means of a switch with a contact separation of at least
0.1" (3 mm).
The installation fuse (all types can be used) must be used for
the power supply line of this conditioner.
