Do not attempt to extend the power cord by joining it to
another cord, or by using an extension cord. Do not put
any other loads on the power supply socket.
An earth leakagebreaker with ratedcapacity must be
installed to avoidpossible electric shocks.
SAFETY PRECAUTION
The following picturesare presented justfor the purposeof illustration.As for somemodels whose
cooling capacity isabove 4600W(17000BTU/h), theirpower cables donot have a plug! So please
take real objectsas a reference.
The items indicatedhere are veryimportant safety precautions,which must befollowed.
Do not putburning appliances atplaces exposed tothe
airflow, itmay cause incompletecombustion.

conditioner at COOL/DRY mode for a long time under high
humidity condition (above 80%). Otherwise, condensed
water may drip from the unit.
The appliance shallbe installed inaccordance with nationalwiring regulations.
The appliance mustnot be installedin the laundry.
The appliance mustbe installed 2.3mabove the floor.
The appliance mustbe positioned sothat the plugis accessible.
For some modelswhose cooling capacityare above 4600W(17000BTU/h),
an all-pole disconnectiondevice which hasat least 3mmseparation distance in
all pole anda residual currentdevice(RCD)with the ratingof above 10mAshall be incorporated
in the fixedwiring according tothe national rule.
Do not insert a finger, a rod or any other objects into the air
outlet/inlet grille. As the fan is running at a high speed, it will
cause injury.

point, please restartthe air conditioner
and stop again.

Indoor unit fanstops
during heating.
The air conditioner is deicing and it takes
10 minutes at most.( It freezes when
outdoor temperature is low and humidity is
high). It automatically resumes operation
about 10 minutes later.
Issue cracking
sounds.
The friction sounds are caused by expansion
and contraction of front grille resulting from
temperature changes.
You can hear the
sound of running
water.
It is the sound of flowing refrigerant inside
the air conditioner.
Sound of accumulated flowing water on the

refrigerant flowing inside the air conditioner.
Indoor unit gives
outdoor.
Air conditioner may have absorbed odors
from wall, carpet, furniture and again blows
out.
Outdoor unit leaks
water.
During cooling, connecting pipe or pipe
connector will cause the moisture content
condensation due to the low temperature.
During heating or defrosting, melting water
and water vapor will run out.
During heating, water on heat exchanger
will drop.
