The refrigerant in the air conditioner is safe and nor-
mally does not leak. If the refrigerant leaks inside the
room, the contact with a fire of a burner, a heater or a
cooker may result in a harmful gas.
Do not use the air conditioner until when a service person
confirms to finish repairing the portion where the refriger-
ant leaks.
Do not use any fuse with improper capacity.
The use of a piece of wire and whatnot may result in a fail-
ure and fire.
Be sure to establish an earth.
Do not earth the unit to a utility pipe, arrester, or tele-
phone earth.
Incomplete earth may cause electrical shock, or fire.
A high surge current from lightning or other sources may
cause damage to the air conditioner.
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in
electric shocks, or fire.
CAUTION
Do not use the air conditioner for other purposes.
Do not use the air conditioner for a special application such
as the storage of foods, animals and plants, precision
machines, and art objects as otherwise the deterioration of
quality may result.
Do not remove the air outlet of the outdoor unit.
The fan may get exposed and result in injury.
When the air conditioner is used in combination with
burners or heaters, perform sufficient ventilation.
Insufficient ventilation may result in an oxygen deficiency
accident.
Check and make sure that foundation blocks are not
damaged after a long use.
If they are left in a damaged condition, the unit may fall and
result in injury.
Neither place a flammable spray bottle near the air
conditioner nor perform spraying.
Doing so may result in a fire.
To clean the air conditioner, stop operation, and
unplug the power cord from the outlet.
Otherwise, an electric shock and injury may result.
Do not operate the air conditioner with a wet hand.
An electric shock may result.
Do not place items which might be damaged by
moisture under the indoor unit which may be dam-
aged by water.
Condensation may form if the humidity is above 80%, if the
drain outlet gets blocked or the filter is polluted.
Do not place a burner or heater at a place directly
exposed to the wind from the air conditioner.
Incomplete combustion of the burner or heater may result.
Do not allow a child to mount on the outdoor unit or
avoid placing any object on it.
Falling or tumbling may result in injury.
Do not expose animals and plants directly to the
wind.
Adverse influence to animals and plants may result.
Do not wash the air conditioner with water.
Electric shock or fire may result.
Do not install the air conditioner at any place where
flammable gas may leak out.
If the gas leaks out and stays around the air conditioner, a
fire may break out.
Execute complete drain piping for perfect drainage.
Incomplete piping may result in a water leakage.
The appliance is not intended for use by young chil-
dren or infirm persons without supervision.
Young children should be supervised to ensure that
they do not play with the appliance.
Consult with installation contractor for cleaning the
inside of the air conditioner.
Wrong cleaning may make the plastics parts broken or
cause failure of water leakage or electric shock.
Do not touch the air inlet or aluminium fin of the air
conditioner.
Otherwise, injury may be caused.
Do not place objects in direct proximity of the out-
door 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 malfunc-
tions, smoke or fire when making contact with electrical
parts.
OPERATION RANGE
If the temperature or the humidity is beyond the following con-
ditions, safety devices may work and the air conditioner may
not operate, or sometimes, water may drop from the indoor
unit.
Cooling
Heating
**–20~–15°CWB: Range for operation
–15~15.5°CWB: Range for continuous operation
DB: Dry bulb temperature WB: Wet bulb temperature
The setting temperature range of the remote controller is
16°C to 32°C.
Tips for saving energy
• Be careful not to cool (heat) the room too much.
Keeping the temperature setting at a moderate level
helps save energy.
• Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors increases the
cooling (heating) effect.
