Operation
• Before opening the intake grille of the indoor unit or service panel of the outdoor unit, set the circuit breaker to the
OFF position. Failure to set the circuit breaker to the OFF position may result in electric shocks through contact with
the interior parts. Only a qualified installer(*1) or qualified service person(*1) is allowed to remove the intake grille of
the indoor unit or service panel of the outdoor unit and do the work required.
• Inside the air conditioner are high-voltage areas and rotating parts. Due to the danger of electric shocks or of your
fingers or physical objects becoming trapped in the rotating parts, do not remove service panel of the outdoor unit.
When work involving the removal of these parts is required, contact a qualified installer or a qualified service person.
• Do not move or repair any unit by yourself. Since there is high voltage inside the unit, you may get electric shock
when removing the cover and main unit.
• Use of a stand more than 50 cm high to clean the filter of the indoor unit or to carry out other such jobs constitutes
working at heights. Due to the danger of falling off the stand and injuring yourself while working at heights, this kind
of work should not be done by unqualified individuals. When this kind of work must be carried out, do not do it yourself
but ask a qualified installer or a qualified service person to do it for you.
• Do not touch the aluminum fin of the outdoor unit. You may injure yourself if you do so. If the fin must be touched, do
not touch it yourself but contact a qualified installer or a qualified service person.
• Do not climb onto or place objects on top of the outdoor unit. You may fall or the objects may fall off of the outdoor
unit and result in injury.
• Do not place any combustion appliance in a place where it is directly exposed to the wind of air conditioner, otherwise
it may cause imperfect combustion.
• When the air conditioner is operated with a combustion appliance in the same place, ventilate the room sufficiently.
Poor ventilation causes oxygen shortage.
• When the air conditioner is used in a closed room, sufficiently ventilate the room. Poor ventilation causes oxygen
shortage.
• Do not expose your body to cool air directly for a long time and do not cool yourself excessively.
Doing so may result in deteriorated physical condition and ill health.
• Do not insert your finger or a stick into the air intake or discharge.
Doing so may result injury as the fan is rotating at high speed inside the unit.
• Consult the shop where you purchased the air conditioner if air conditioning (cooling and heating) is not performed
properly as a refrigerant leakage may be the cause. Confirm the repair details with a qualified service person(*1)
when the repair includes additional charging of the refrigerant.
• Stop running the air conditioner and turn off the breaker before cleaning.
Otherwise, injury may result as the fan is rotating at high speed inside the unit.
Repairs
• If there is any kind of trouble (such as when an error display has appeared, there is a smell of burning, abnormal
sounds are heard, the air conditioner fails to cool or heat or water is leaking) has occurred in the air conditioner, do
not touch the air conditioner yourself but set the circuit breaker to the OFF position, and contact a qualified service
person. Take steps to ensure that the power will not be turned on (by marking “out of service” near the circuit breaker,
for instance) until qualified service person arrives. Continuing to use the air conditioner in the trouble status may
cause mechanical problems to escalate or result in electric shocks or other trouble.
• If the fan grille is damaged, do not approach the outdoor unit but set the circuit breaker to the OFF position, and
contact a qualified service person to have the repairs done. Do not set the circuit breaker to the ON position until the
repairs are completed.
• If there is a danger of the indoor unit’s falling, do not approach the indoor unit but set the circuit breaker to the OFF
position, and contact a qualified installer or a qualified service person to refit the unit. Do not set the circuit breaker
to the ON position until the unit has been refitted.
• If there is a danger of the outdoor unit’s toppling over, do not approach the outdoor unit but set the circuit breaker to
the OFF position, and contact a qualified installer or a qualified service person to have the improvements or refitting
done. Do not set the circuit breaker to the ON position until the improvements or refitting is completed.
• Do not customize the unit. Doing so may result in fire, electric shock or other trouble.
Relocation
• When the air conditioner is to be relocated, do not relocate it yourself but contact a qualified installer or a qualified
service person. Failure to relocate the air conditioner properly may result in electric shocks and / or a fire.
CAUTION
To disconnect the appliance from the mains supply.
• This appliance must be connected to the mains by means of a switch with a contact separation of at least
3 mm
.
The installation fuse (all types can be used) must be used for the power supply line of this air conditioner.
Installation
• Certainly lay the drain hose for perfect draining. Improper drainage may cause flooding in the house and getting
furniture wet.
• Connect the air conditioner to an exclusive power supply of the rated voltage, otherwise the unit may break down or
cause a fire.
• Confirm that the outdoor unit are fixed on the base. Otherwise, falling down of the units or other accidents may occur.

• Do not use this air conditioner for special purpose such as preserving food, precision instruments, art objects,
breeding animals, car, vessel.
• Do not touch any switches with wet finger, otherwise you may get an electric shock.
• If the air conditioner will not be used for a considerably long time, turn off the main switch or the circuit breaker, for
safety.
• To make the air conditioner operate in its original performance, operate it within the range of the operating
temperature specified in the instructions. Otherwise it may cause a malfunction, or water leak from the unit.
• Prevent any liquid from falling into the remote controller. Do not spill juice, water or any kind of liquid.
• Do not wash the air conditioner. Doing so may result in electric shock.
• Check whether the installation base and other equipment have become deteriorated after being used for a long time.
Leaving them such condition may result in the unit’s falling down and causing injury.
• Do not leave flammable sprays or other flammable materials near the air conditioner, and do not spray flammable
aerosol directly to the air conditioner. They may catch fire.
• Stop running the air conditioner and turn off the breaker before cleaning.
Otherwise, injury may result as the fan is rotating at high speed inside the unit.
• Ask for cleaning of the air conditioner to be performed by the dealer.
Cleaning the air conditioner in an improper manner may cause damage to plastic parts, insulation failure of electric
parts or other parts, and result in a malfunction. In the worst case, it may result in water leakage, electric shock,
smoke emission or fire.
• Do not put a water container such as a vase on the unit.
Water intrusion into the unit may occur and it may cause deterioration of electric insulation and result in electric shock.
