Upon completion of the installation work, check for refrigerant
•
leaks and check the insulation resistance and water drainage.
Then conduct a test run to check that the air conditioner is
operating properly.
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.
•
After the installation work, follow the Owner's Manual to explain
to the customer how to use and maintain the unit.
Relocation
Only a qualifi ed installer or qualifi ed service person is allowed to
•
relocate the air conditioner. It is dangerous for the air conditioner
to be relocated by an unqualifi ed individual since a fi re, 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 environmentally 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.
