refrigerant leakage. If any refrigerant leakage is found, stop operations
and ventilate the room well and consult your dealer immediately. If a
repair involves recharging the unit with refrigerant, ask the service
technician for details.
• The refrigerant used in the air conditioner is not harmful. Normally, it
does not leak. However, if refrigerant leaks and comes in contact with
fi re or heating part of such a fan heater, kerosene heater, or cooking
stove, it will create harmful gas and there is risk of fi re.
The user should never attempt to wash the inside of the indoor unit.
Should the inside of the unit require cleaning, contact your dealer.
• Unsuitable detergent may cause damage to plastic material inside
the unit, which may result in water leakage. Should detergent come in
contact with electrical parts or the motor, it will result in a malfunction,
smoke, or fi re.
• The appliance shall be stored in a room without continuously operating
ignition sources (for example: open fl ames, an operating gas appliance
or an operating electric heater).
• Be aware that refrigerants may not contain an odour.
• Do not use means to accelerate the defrosting process or to clean the
appliance, other than those recommended by the manufacturer.
• Do not pierce or burn.
The indoor unit must be installed in rooms which exceed the fl oor
space specifi ed. Please consult your dealer.
