Safety precautions
CAUTION
• Do not turn off the breaker unless you smell something burning, or when doing repairs, inspection or
cleaning of the unit (only for R32 refrigerant).
Refrigerant leakage cannot be detected otherwise (only for R32 refrigerant).
• Do not use flammable substances (such as hairsprays or insecticides etc.) near the unit.
It could cause electric shock, fire, or a misdetection of the refrigerant sensor (only for R32
refrigerant).
• Do not install in sealed, highly airtight spaces such as soundproof chambers and room which was
sealed up the door (only for R32 refrigerant).
• Do not install in places filled with smoke, gas, chemicals etc.
There is a possibility that the sensors inside the indoor unit could detect these, and display a
refrigerant leak abnormality (only for R32 refrigerant).
• This unit is equipped with a refrigerant leak detector for safety. To be effective, the unit must be
electrically powered at all times after installation, other than short service intervals (only for R32
refrigerant).
• This unit is equipped with electrically powered safety measures. To be effective, the unit must be
electrically powered at all times after installation, other than short service intervals (only for R32
refrigerant).
• To avoid oxygen depletion, ensure that the room is adequately ventilated if equipment such
as a burner is used together with the air conditioner.
• Before cleaning, be sure to stop unit operation, turn off the circuit breaker or remove the
power cord. Otherwise, an electric shock and injury may result.
After cleaning, quickly turn the power supply breaker back on.
• Only connect the air conditioner to the specified power supply circuit. Power supplies other than the
one specified may result in electric shocks, overheating and fires.
• Arrange the drain hose to ensure smooth drainage. Imperfect drainage may cause wetting of the
building, furniture etc.
• Do not place objects in direct proximity of the outdoor unit and do not let leaves and other debris
accumulate around the unit. Leaves are a hotbed for small animals which can enter the unit. Once in
the unit, such animals can cause malfunctions, smoke or fire when making contact with electrical
parts.
• Do not place objects around the indoor unit.
• Doing so may have an adverse influence on the performance, product quality, and life of the air
conditioner.
• Keep out of children’s reach to ensure that they do not play with the appliance.
• Do not operate the air conditioner with wet hands.
• Do not wash the indoor unit with excessive water, only use a slightly wet cloth.
• Do not place things such as vessels containing water or anything else on top of the unit. Water
may penetrate into the unit and degrade electrical insulations, resulting in an electric shock.
