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 or qualified service person 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 the
intake grille of the indoor unit or 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 for some reason, first
put on protective gloves and safety work clothing, and then proceed.
• 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, be careful of ventilation to let fresh air enter the
room. Poor ventilation causes oxygen shortage.
• When the air conditioner is used in a closed room, be careful of
sufficient ventilation of 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.
• Never 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 when the repair includes additional
charging of the refrigerant.
• Be sure to 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
• When you have noticed that some 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, etc.
• If you have discovered that the fangard is damaged, do not
approach the outdoor unit but set the circuit breaker to the OFF
