The unit must be properly earth connected.
Do not connect the earth wire to gas pipe, city water pipe, lightning rod or telephone earth wire.
Improper earth connection may cause electrical shock.
When installing at a watery place, provide an electric leak breaker.
Failure to mount the electric leak breaker may cause electrical shock.
Use breaker or fuse with proper capacity.
Make sure that each appliance has a main power switch.
Using a wire or copper wire instead of proper capacity can cause fire or trouble.
Other appliances connected to the same line could cause an overload.
For the power lines, use standard cables of sufficient current capacity.
Otherwise, current leakage, overheating or fire may occur.
When installing the power lines, do not apply tension to the cables.
The tighten or loosen the connections may cause generate heat and cause fire.
A thing embarrassed which gets wet under the unit is not put.
When the room is high humidity or when the drain pipe is clogged, water may drip from the indoor unit.
Arrange the configuration of wiring not to bring up the panel and terminal cover, and fasten the panel and terminal cover securely.
The poor mounting of the panel or terminal cover may cause the heat generation of the terminal connection, a fire or electrical shock.
Do not wash the unit with water.
If washed with water, electric shock may be caused.
Do not handle the switch with wet hands.
