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 check code 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 VMΩ) 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.
• 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 (*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.
11-EN
• 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.
(*1) Refer to the "Definition of qualified installer or qualified service person".
CAUTION
This Air Conditioner has adopted a refrigerant HFC (R32 or
R410A) which does not destroy the ozone layer.
• As the R32 or R410A refrigerant is easily affected by impurities such
as moisture, oxidized film, oil, etc., due to the high pressure, be
careful not to allow the moisture, dirt, existing refrigerant, refrigerating
machine oil, etc., to get mixed up in the refrigeration cycle during the
installation work.
• A special tool for the R32 or R410A refrigerant is required for
installation.
• Use a new and clean piping materials for the connecting pipe so that
moisture and dirt are not mixed together during the installation work.
• When using existing pipes, follow the installation manual enclosed
with the outdoor unit.
• Be careful of fan operation when the circuit breaker is turned on. If the
refrigerant leak detection sensor detects the refrigerant leak, a fan
automatically rotates even while an air conditioner stops. Be careful
not to be injured by the fan.
