				CONNECT EARTH LINE
		shock.
	•	Be sure to use the specified piping set for R410A. Otherwise, this may result in
		broken copper pipes or faults.
	•	A circuit breaker should be installed depending on the mounting site of the unit.
		Without a circuit breaker, the danger of electric shock exists.
	•	Do not install the unit near a location where there is flammable gas.
		The outdoor unit may catch fire if flammable gas leaks around it. Piping shall be		PROHIBITION
		suitable supported with a maximum spacing of 1m between the supports.
CAUTION •		Please ensure smooth flow of water when installing the drain hose. If any failure
		is found in the drain path, water drops from the indoor and outdoor units, causing
		wet household effects.

•Make sure that a single phase 230V power source is used.

The use of other power sources may cause electrical components to overheat

and lead to fire.

PROHIBITION

PRECAUTIONS DURING SHIFTING OR MAINTENANCE

• Should abnormal situation arise (like burning smell), please stop operating the unit and remove plug from the socket or turn off the circuit breaker. Contact your

	leads of the other electric appliance into the socket where this cable is plugged.
	In addition, wire the cable with some allowances to prevent the cable from stretching.
	Not doing so will cause an electrical shock, heat generation or fire.	PROHIBITION
•	Do not bundle the power cable, pull it, put something on it, heat it, process it, or
	put it between things. Breakage of the power cable may result.
	Use of a damaged cable may cause an electrical shock or a fire.	PROHIBITION
