When you access inside of the electric cover 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.
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.
When checking the electric parts, removing the cover of the electric parts box of Indoor Unit and/
or front panel of Outdoor Unit inevitably to determine the failure, put a sign “Do not enter” around
the site before the work. Failure to do this may result in third person getting electric shock.
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.
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 (
䌫
1) is allowed to do this kind of work.
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 electric engineer 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.
Do not modify the products. Do not also disassemble or modify the parts.
It may cause a fire, electric shock or injury.
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.
Replace components only with parts specified by the manufacturer. Other parts may result
in the ignition of refrigerant in the atmosphere from a leak.
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, place
Keep out signs around the work site before proceeding. Third-party individuals may enter the
work site and receive electric shocks if this warning is not heeded.
Connect the cut-off lead wires with crimp contact, etc., put the closed end side upward and then
apply a water-cut method, otherwise a leak or production of fire is caused at the users’ side.
