conditioner by following its instructions.
Electric
shock
hazard
Prohibition
Only qualified service person (
∗
1) is allowed to repair the air conditioner. Repair of the air conditioner by
unqualified person may give rise to a fire, electric shocks, injury, water leaks and/or other problems.
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.
Wear protective gloves and safety work clothing during installation, servicing and removal.
Do not use any refrigerant different from the one specified for complement or replacement.
Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may result in a
failure or explosion of the product or an injury to your body.
When connecting the electrical wires, repairing the electrical parts or undertaking other electrical jobs, wear
gloves to provide protection for electricians, insulating shoes and clothing to provide protection from electric
shocks. Failure to wear this protective gear may result in electric shocks.
When the air conditioner is to be transported, installed, maintained, repaired or removed, wear protective
gloves and safety work clothing.
To connect the electrical wires, repair the electrical parts or undertake other electrical jobs, wear gloves to
provide protection for electricians, insulating shoes and clothing to provide protection from electric shocks.
Failure to wear this protective gear may result in electric shocks.
Electrical wiring work shall be conducted according to law and regulation in the community and installation
manual. Failure to do so may result in electrocution or short circuit.
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.
Only a qualified installer (
∗
1) or qualified service person (
∗
1) is allowed to undertake work at heights using
a stand of 50 cm or more.
When working at heights, use a ladder which complies with the I
S
O 14122 standard, and follow the
procedure in the ladder fs instructions. Also wear a helmet for use in industry as protective gear to
undertake the work.
When working at heights, put a sign in place so that no-one will approach the work location, before
proceeding with the work. Parts and other objects may fall from above, possibly injuring a person below.
When executing address setting, test run, or troubleshooting through the checking window on the electric
parts box, put on insulated gloves to provide protection from electric shock.
Otherwise you may receive an electric shock.
Do not touch the aluminum fin of the outdoor unit. You may injure yourself if you do so.
If the fin must be touched for some reason, first put on protective gloves and safety work clothing, and then
proceed.
Do not climb onto or place objects on top of the outdoor unit.
You may fall or the objects may fall off of the outdoor unit and result in injury.
When transporting the air conditioner, wear shoes with additional protective toe caps.
When transporting the air conditioner, do not take hold of the bands around the packing carton.
You may injure yourself if the bands should break.
Be sure that a heavy unit (10 kg or heavier) such as a compressor is carried by four persons.
This air conditioner has passed the pressure test as specified in IEC 60335-2-40 Annex EE.
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.
