Insulating
measures
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 earth wires are connected properly.
Be sure to connect earth wire. (Grounding work) Incomplete earth causes an electric shock.
Do not connect earth wires to gas pipes, water pipes, and lightning rods or earth 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 that do not satisfy the required specifications may give rise to electric shocks,
smoking and/or a fire.
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

apply a water-cut method, otherwise a leak or production of fire is caused at the users’ side.
No fire
When performing repairs using a gas burner, replace the refrigerant with nitrogen gas because
the oil that coats the pipes may otherwise burn.
When repairing the refrigerating cycle, take the following measures.
1) Be attentive to fire around the cycle.
When using a gas stove, etc. be sure to put out fire before work; otherwise the oil mixed with
refrigerant gas may catch fire.
2) Do not use a brazing in the closed room.
When using it without ventilation, carbon monoxide poisoning may be caused.
3) Do not bring inflammable material around to the refrigerant cycle; otherwise fire of the brazing
may catch the inflammable material.
