Test run
• Before operating the air conditioner after having completed the work,
check that the electrical control box cover of the indoor unit and
service panel of the outdoor unit are closed, and set the circuit
breaker to the ON position. You may receive an electric shock if the
power is turned on without first conducting these checks.
• If there is any kind of trouble (such as an error display has appeared,
smell of burning, abnormal sounds, the air conditioner fails to cool or
heat or water is leaking) has occurred in the air conditioner, do not
touch the air conditioner yourself but set the circuit breaker to the OFF
position, and contact a qualified service person. Take steps to ensure
that the power will not be turned on (by marking "out of service" near
the circuit breaker, for instance) until qualified service person arrives.
Continuing to use the air conditioner in the trouble status may cause
mechanical problems to escalate or result in electric shocks or other
trouble.
• After the work has finished, use an insulation tester set (500 V
Megger) to check the resistance is 1 MΩ or more between the charge
section and the non-charge metal section (Earth section). If the
resistance value is low, a disaster such as a leak or electric shock is
caused at user's side.
• 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.
• If the fan grille is damaged, do not approach the outdoor unit but set
the circuit breaker to the OFF position, and contact a qualified service
person(*1) to have the repairs done. Do not set the circuit breaker to
the ON position until the repairs are completed.

Relocation
• Only a qualified installer(*1) or qualified service person(*1) is allowed
to relocate the air conditioner. It is dangerous for the air conditioner
to be relocated by an unqualified 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 adopts the new HFC refrigerant (R410A)
which does not destroy ozone layer.
• The characteristics of R410A refrigerant are; easy to absorb water,
oxidizing membrane or oil, and its pressure is approx. 1.6 times
higher than that of refrigerant R22. 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.
