·Install the unit securely in a place which can bear the weight of the unit.
When installed in an insufficient strong place, the unit could fall and cause injury.
·Use the specified wires to connect the indoor and outdoor units securely and attach the wires firmly to the terminal
block connecting sections so that the stress of the wires is not applied to the sections.
Incomplete connecting and fixing could cause fire.
·Do not use intermediate connection of the power cord or the extension cord and do not connect many devices to
one AC outlet.
It could cause a fire or an electric shock due to defective contact, defective insulation ,exceeding the permissible current, etc.
·Check that the refrigerant gas does not leak after installation has completed.
If refrigerant gas leaks indoors, and comes into contact with the fire of a fan heater, space heater, stove, etc., harmful substances
will be generated.
·Perform the installation securely referring to the installation manual.
Incomplete installation could cause a personal injury due to fire, electric shock, the unit falling or leakage of water.
·Perform electrical work according to the installation manual and be sure to use an exclusive circuit.
If the capacity of the power circuit is insufficient or there is insufficient electrical work ,it could result in a fire or an electric shock
·Attach the electrical cover to the indoor unit and the service panel to the outdoor unit securely.
If the electrical cover in the indoor unit and/or the service panel in the outdoor unit are not attached securely, it could result in

a fire or an electric shock due to dust water, etc.
·
It could cause an electric shock.
·The appliance shall be installed in accordance with national wiring regulations.
·When installing or relocating the unit, make sure that no substance other than the specified refrigerant(R410A) enters
the refrigerant circuit.
Any presence of foreign substance such as air can cause abnormal pressure rise or an explosion.
Be sure to cut off the main power in case of setting up the indoor electronic control P. C. Board or wiring works.
CAUTION
·Perform earthing.
Do not connect the earth wire to a gas pipe, water pipe, lightning rod or telephone earth wire. Defective earthing could cause an
electric shock.
·Do not install the unit in a place where an inflammable gas leaks.
If gas leaks and accumulates in the area surrounding the unit, it could cause an explosion.
·Fasten a flare nut with torque wrench as specified in this manual.
When fastened too tight, a flare nut may break after a long period and cause a leakage of refrigerant.
·Install an earth leakage breaker depending on the installation place(where it is humid).
If a earth leakage breaker is not installed, it could cause an electric shock.
·Check that the refrigerant gas does not leak after installation has completed.
If refrigerant gas leaks indoors, and comes into contact with the fire of a fan heater, space heater, stove, etc., harmful substances
will be generated.
·Perform the drainage/piping work securely according to the installation manual.
If there is a defect in the drainage/piping work, water could drop from the unit and household goods could be wet and damaged..
