SAFETY PRECAUTIONS
CAUTION
Never modify or disassembling the air conditioning system. If it
requires service, consult the dealer from whom you purchased
the air conditioning system.
If servicing is inadequate, water leakage, electric shock and/or fire may occur.
The refrigerant used in the air conditioning system is safe. The refrigerant
usually does not leak, but if it leaks inside the room and gets into contact with
flames, for instance from a fan heater, space heater, cooking stove, toxic
gases may be generated.
When you receive service for leakage of the refrigerant, make sure to confirm
with the service personnel that the leakage areas have been repaired
correctly.
If it is required to move and reinstall the air conditioning
system, consult a dealer or specialist.
If the air conditioning system is installed incorrectly, water leakage, electric
shock and/or fire may occur.
❚ PRECAUTIONS FOR TRANSFER OR REPAIR
DANGER
If the refrigerant leaks and the critical concentration is
exceeded, accidents may occur due to oxygen
deficiency. Moreover, if the refrigerant gets into contact
with flames, for instance from a fan heater, space
heater, cooking stove, toxic gases may be generated. If
the refrigerant is found to be leaking, extinguish any
flames in the room and ventilate the room.
If the air conditioning system is submerged under water due to a natural
disaster such as a flood or a typhoon,
consult the dealer from whom you
purchased the air conditioning system.
Operating the air conditioning system under such
conditions may lead to failure, electric shock and/or
fire.
Do not insert fingers and/or other
elongated devices in the air outlet and
inlet openings.
The fan inside rotates at high speeds, leading to
injury.
The blower, even if it is stopped, may
suddenly begin to operate; do not
insert fingers and/or other elongated
devices.
Performing such acts may cause injury.
DANGER
Do not operate the switches with wet
hands.
It may lead to electric shock.
If the air conditioning system is operated
in an environment where burning
appliances are used, make sure to
ventilate the room frequently.
If the ventilation is insufficient, accidents due to
oxygen deficiency may occur.
When you clean the air conditioning
system, make sure to stop the operation and turn the power supply switch
off.
The fan inside rotates at high speeds, leading to
injury.
Make sure that the installation foundation etc. is not damaged due to longterm use.
If it is left under damaged conditions, the unit
may fall down, causing injury.
Do not wash the air conditioning system
with water. In case of washing the unit
consult the dealer from whom you
purchased the air conditioning system.
It may cause electric shock.
Make sure to use only fuses of the right
capacity.
Using wire or copper wire may lead to failure and/
or fire.
CAUTION
Do not allow combustible spray near
the air conditioning system, nor spray
it directly to the air conditioning
system.
It may catch fire.
Do not sit on the air conditioning system
or place objects on it.
The air conditioning system may fall down or
overturn, leading to injury.
Do not use the air conditioning system
with the outlet/inlet grills removed.
It may lead to injury.
If the swing louver is operating, do not
touch the outlet opening.
It may lead to injury.
Do not operate or stop the air conditioning system with the power supply switch.
It may cause fire and/or water leakage. Moreover,
if the power failure compensation is enabled, the
fan may start rotating suddenly, leading to injury.
Do not pull the remote controller cable
out.
Part of the conductor may be disconnected,
leading to electric leakage.
Do not use appliances such as water
heaters near the indoor unit and remote
controller.
If appliances generating vapor are used near the
indoor unit and/or remote controller, water drops
may condensate at the cooling operation or
electric leakage/short circuit may occur.
❚ PRECAUTIONS FOR WASTE DISPOSAL
Your Air Conditioning product may be marked with this symbol. It means that waste electrical and electronic equipment (WEEE as in
directive 2002/96/EC) should not be mixed with general household waste. Air conditioners should be treated at an authorized treatment
facility for re-use, recycling and recovery and not be disposed of in the municipal waste stream. Please contact the installer or local
authority for more information.
Do not place objects below the air
conditioner that might be damaged by
dampness or moisture.
If the drain clogs or humidity rises to 80% or
higher, then vapor from the indoor unit might
form into droplets and cause damage.
Always switch off the “indoor unit power supply breaker”
before inspecting or repairing the indoor unit.
Doing inspection or repair work with the indoor unit power supply breaker ON
can result in injury from electrical shock or from the rotation of the indoor unit
fan.
●
When you operate the air conditioning system at the start of the season or after it has been stopped for a prolonged
period, turn the power switch on (ON) 12 hours before starting the air conditioning operation in order to protect the
air conditioning system (the current is conducted into the crank case and warms the compressor). Do not turn the power
supply switch off during the season. (The current is conducted to the crank case heater while the compressor is stopped,
keeping the compressor warm and preventing failure of the compressor due to accumulation of liquid refrigerant.)
● Do not turn the power supply switch off during the season. Do not turn the power supply switch of an
unused indoor unit off either, keep it “ON.” If the power supply to one of the indoor units in the same
system is turned off, water may leak from the indoor unit (drained water overflows).
●
Turn the power supply switch off during the off-season in order to save electricity. (If the power supply switch is kept turned on, current
continues to be conducted to the crank case heater and power is consumed even if the air conditioning system is not operated.)
