Installation
• Only a Qualified installer (*1) or Qualified service person (*1) is
allowed to carry out the electrical work of the air conditioner. Under
no circumstances must this work be done by an unqualified individual
since failure to carry out the work properly may result in electric
shocks and / or electrical leaks.
• After the installation work has been completed, have the installer
explain about the circuit breaker positions. In the event that trouble
has occurred in the air conditioner, set the circuit breaker to the OFF
position, and contact a service person.
• If the unit is installed in a small room, take appropriate measures to
prevent the refrigerant from exceeding the limit concentration even if
it leaks. Consult the dealer from whom you purchased the air
conditioner when you implement the measures. Accumulation of
highly concentrated refrigerant may cause an oxygen deficiency
accident.
• Do not install the air conditioner in a location that may be subject to a
risk of expire to a combustible gas. If a combustible gas leaks and
becomes concentrated around the unit, a fire may occur.
• Use the company-specified products for the separately purchased
parts. Use of non-specified products may result in fire, electric shock,
water leakage or other trouble. Have the installation performed by a
professional.
• Confirm that earthing is performed correctly.
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 (*1) or a Qualified
service person (*1).
• 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.

• 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 (*1) or a Qualified service
person (*1).
• Do not climb onto or place objects on top of the outdoor unit. You may
fall or the objects may fall top 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.
• Do not turn off the circuit breaker except when there is a smell of
burning or an air conditioner is checked.
Turning off the circuit breaker cause refrigerant leak detection sensor
not to operate, if refrigerant leaks and come in contact with fire, a fire
occurs.
• If check codes "J29" or "J31" appear on the remote controller LCD
(Liquid Crystal Display), replace a refrigerant leak detection sensor.
Contact the dealer where you purchased the air conditioner to replace
the refrigerant leak detection sensor. Continuing to use the air
conditioner in the status above may cause a fire in case refrigerant
leak occurs.
• When there is the risk of R32 refrigerant leak, do not use a
combustion appliance near the air conditioner. Check code "J30"
appears on the remote controller LCD while air conditioner operates.
When a fan is automatically operating while air conditioner stops and
it does not shut off even if ON/OFF button is pushed, R32 refrigerant
may be leaking. Ventilate the room and do not turn off the circuit
breaker, and contact the dealer where you purchased the product.
