DANGER
WARNING
Turn off
breaker.
Before carrying out the installation, maintenance, repair or removal work, be sure to set the circuit breaker for
both the indoor and outdoor units to the OFF position. Otherwise, electric shocks may result.
Before opening the front panel of the indoor unit or service panel of the outdoor unit, set the circuit breaker to
the OFF position.
Failure to set the circuit breaker to the OFF position may result in electric shocks through contact with the interior
parts.
Only a qualified installer (*1) or qualified service person (*1) is allowed to remove the intake grille of the indoor
unit or service panel of the outdoor unit and do the work required.
Before starting to repair the outdoor unit fan or fan guard, be absolutely sure to set the circuit
breaker to the OFF position, and place a “Work in progress” sign on the circuit breaker.
When cleaning the filter or other parts of the indoor unit, set the circuit breaker to OFF without
fail, and place a “Work in progress” sign near the circuit breaker before proceeding with the work.
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 or
other failure.
Electric shock
hazard
When you access inside of the service panel to repair electric parts, wait for about five minutes after turning off
the breaker. Do not start repairing immediately.Otherwise you may get electric shock by touching terminals of
high-voltage capacitors. Natural discharge of the capacitor takes about five minutes.
Prohibition
Place a “Work in progress” sign near the circuit breaker while the installation, maintenance, repair or removal
work is being carried out.
There is a danger of electric shocks if the circuit breaker is set to ON by mistake.
Before operating the air conditioner after having completed the work, check that the front panel
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.
Stay on
protection
If, in the course of carrying out repairs, it becomes absolutely necessary to check out the electrical parts with
the electrical parts box cover of one or more of the indoor units and the service panel of the outdoor unit
removed in order to find out exactly where the trouble lies, wear insulated heat-resistant gloves, insulated boots
and insulated work overalls, and take care to avoid touching any live parts.
You may receive an electric shock if you fail to heed this warning. Only qualified service person (*1) is allowed
to do this kind of work.
Check earth
wires.
Before troubleshooting or repair work, check the earth wire is connected to the earth terminals of the main unit,
otherwise an electric shock is caused when a leak occurs.If the earth wire is not correctly connected, contact
an qualified service person for rework.
After completing the repair or relocation work, check that the ground wires are connected properly.
Be sure to connect earth wire. (Grounding work) Incomplete grounding causes an electric shock.
Do not connect ground wires to gas pipes, water pipes, and lightning rods or ground wires for telephone wires.
Prohibition of
modification.
Do not modify the products.Do not also disassemble or modify the parts.
It may cause a fire, electric shock or injury.
Use specified
parts.
When any of the electrical parts are to be replaced, ensure that the replacement parts satisfy the specifications
given in the Service Manual (or use the parts contained on the parts list in the Service Manual).
Use of any parts which do not satisfy the required specifications may give rise to electric shocks, smoking and/
or a fire.
