• The charge hose must be connected in such a way that it is not
slack.
• If refrigerant gas has leaked during the installation work, ventilate
the room immediately. If the leaked refrigerant gas comes in
contact with fire, noxious gas may be generated.
Electrical wiring
• Only a qualified installer (*1) or qualified service person (*1) is
allowed to carry out the electrical work of the air conditioner. Under
no circumstances must this work be done by an unqualified
individual since failure to carry out the work properly may result in
electric shocks and/or electrical leaks.
• When connecting the electrical wires, repairing the electrical parts
or undertaking other electrical jobs, wear gloves to provide
protection for electricians and from heat, insulating shoes and
clothing to provide protection from electric shocks. Failure to wear
this protective gear may result in electric shocks.
• Use wiring that meets the specifications in the Installation Manual
and the stipulations in the local regulations and laws. Use of wiring
which does not meet the specifications may give rise to electric
shocks, electrical leakage, smoking and/or a fire.
• Be sure to connect earth wire. (Grounding work)
Incomplete earthing causes an electric shock.
• Do not connect earth wires to gas pipes, water pipes, and lightning
rods or earth wires for telephone wires.
• After completing the repair or relocation work, check that the earth
wires are connected properly.
• Install a circuit breaker that meets the specifications in the
Installation Manual and the stipulations in the local regulations and
laws.
• Install the circuit breaker where it can be easily accessed by the
agent.
• When installing the circuit breaker outdoors, install one which is
designed to be used outdoors.
• Under no circumstances must the power cable be extended.
Connection trouble in the places where the cable is extended may
give rise to smoking and/or a fire.
• Electrical wiring work shall be conducted according to law and
regulation in the community and the Installation Manual. Failure to
do so may result in electrocution or short circuit.
Test run
• Before operating the air conditioner after having completed the
work, check that the electrical parts 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.
• When you have noticed that some kind of trouble (such as when an
error display has appeared, there is a smell of burning, abnormal
sounds are heard, 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, etc.
