to clean, other than those
recommended by manufacturer.
Any unfit method or using
incompatible material may cause
product damage, burst and
serious injury.
Do not pierce or burn as the
appliance is pressurized. Do not
expose the appliance to heat,
flame, sparks, or other sources
of ignition. Else it may explode
and cause injury or death.
Do not install the unit in
a potentially explosive or
flammable atmosphere.
Failure to do so could result in
fire.
Do not insert your fingers
or other objects into the
air conditioner indoor or
outdoor unit, rotating parts
may cause injury.

avoid excess cooling.
Do not sit or step on the
unit, you may fall down
accidentally.
Remote control
Do not allow infants and small
children to play with the remote
control to prevent them from
accidentally swallowing the
batteries.
Power supply
Do not use a
modified cord, joint
cord, extension cord
or unspecified cord to
prevent overheating
and fire.
To prevent overheating, fire or
electric shock:
•Do not share the same power
outlet with other equipment.
•Do not operate with wet hands.
•Do not over bend the power
supply cord.
•Do not operate or stop the unit
by inserting or pulling out the
power plug.
If the supply cord is damaged,
it must be replaced by the
manufacturer, service agent or
similarly qualified persons in
order to avoid a hazard.
It is strongly recommended to
be installed with Earth Leakage
Circuit Breaker (ELCB) or
Residual Current Device (RCD)
to prevent electric shock or fire.
To prevent overheating, fire or
electric shock:
•Insert the power plug properly.
•Dust on the power plug should
be periodically wiped with a dry
cloth.
Stop using the product if any
abnormality/failure occurs and
disconnect the power plug or
turn off the power switch and
breaker.
(Risk of smoke/fire/electric
shock)
Examples of abnormality/failure
•The ELCB trips frequently.
•Burning smell is observed.
•Abnormal noise or vibration of
the unit is observed.
•
Water leaks from the indoor unit.
•Power cord or plug becomes
abnormally hot.

Safety precautions
WARNING
Precaution for appliance filled
with R32
Pay careful attention to the following
points when operating the appliances
and dealing with different refrigerants.
The appliance shall be installed,
and/or operated in a room with
floor area larger than Amin (m²)
and keep away from ignition
sources, such as heat/sparks/
open flame or hazardous areas
such as gas appliances, gas
cooking, reticulated gas supply
systems or electric cooking
appliances, etc. (Refer to Table
A of Installation instructions table
for Amin (m²))
Be aware that refrigerant may
not contain an odour, highly
recommended to ensure suitable
flammable refrigerant gas
detectors are present, operating
and able to warn of a leak.
Since the working pressure is
higher than that of refrigerant
R22 models, some of the piping
and installation and service tools
are special.
Especially, when replacing a
refrigerant R22 model with a new
refrigerant R32 model, always
replace the conventional piping
and flare nuts with the R32 and
R410A piping and flare nuts on
the outdoor unit side.
The R32 flare nut and pipe on
the outdoor unit side can also be
used for a R410A model.
Models that use refrigerant R32
and R410A have a different
charging port thread diameter to
prevent erroneous charging with
refrigerant R22 and for safety.
Therefore, check beforehand.
[The charging port thread
diameter for R32 and R410A is
12.7 mm (1/2 inch).]
Be extra careful so that foreign
matter (oil, water, etc.) does not
enter the piping.
Also, when storing the piping,
securely seal the opening by
pinching, taping, etc. (Handling
of R32 is similar to R410A.)
This appliance shall be stored in
a well ventilated area.
This appliance shall be stored
in a room without continuously
operating open flames and
ignition sources.
This appliance shall be stored
so as to prevent mechanical
damage from occurring.
Do not use means to accelerate
the defrosting process or
to clean, other than those
recommended by manufacturer.
Any unfit method or using
incompatible material may cause
product damage, burst and
serious injury.
This equipment must be earthed
to prevent electrical shock or fire.
Prevent electric shock by
switching off the power supply
and unplug:
-Before cleaning or servicing,
-When extended non-use, or
-During abnormally strong
lightning activity.

container on the unit. Water may
enter the unit and degrade the
insulation. This may cause an
electric shock.
Do not open window or door
for long time during operation,
it may lead to inefficient power
usage and uncomfortable
temperature changes.
Prevent water leakage by
ensuring drainage pipe is:
-Connected properly,
-Kept clear of gutters and
containers, or
-Not immersed in water
After a long period of use or use
with any combustible equipment,
aerate the room regularly.
After a long period of use, make
sure the installation rack does
not deteriorate to prevent the unit
from falling down.
Remote control
Do not use rechargeable (Ni-Cd)
batteries. It may damage the
remote control.
To prevent malfunction or
damage of the remote control:
•Remove the batteries if the unit
is not going to be used for a
long period of time.
•New batteries of the same type
must be inserted following the
polarity stated.
Power supply
Do not disconnect the plug
by pulling the cord to prevent
electric shock.
Do not pierce or burn as the
appliance is pressurized. Do not
expose the appliance to heat,
flame, sparks, or other sources
of ignition. Else it may explode
and cause injury or death.

The following symptoms do not indicate malfunction.
Symptom Cause
POWER indicator blinks before the unit is
switched on.
• This is a preliminary step in preparation for the
operation when the ON timer has been set.
• When ON Timer is set, the unit may start earlier (up
to 35 minutes) before the actual set time in order to
achieve the desired temperature on time.
POWER indicator blinks during HEAT
mode with no warm air supply (and flap is
closed).
• The unit is in defrost mode (and AIR SWING is set
to AUTO).
TIMER indicator is always on.
• The timer setting repeats daily once set.
Operation is delayed a few minutes after
restarting.
• The delay is a protection to the unit’s compressor.
Indoor fan stops occasionally during
heating operation.
• To avoid unintended cooling effect.
Indoor fan stops occasionally during
automatic fan speed setting.
• This helps to remove the surrounding odour.
Airflow continues even after operation has
stopped.
• Extraction of remaining heat from the indoor unit
(maximum 30 seconds).
The room has a peculiar odour.
• This may be due to damp smell emitted by the wall,
carpet, furniture or clothing.
Cracking sound during operation.
• Changes of temperature caused the expansion/
contraction of the unit.
Water flowing sound during operation.
• Refrigerant flow inside the unit.
Mist emerges from indoor unit.
• Condensation effect due to cooling process.
Outdoor unit emits water/steam.
• Condensation or evaporation occurs on pipes.
Louder noise at outdoor unit during early
operation of i AUTO-X.
• The compressor and fan rotate at higher speed to
boost cooling performance during initial operation.
Discoloration of some plastic parts.
• Discoloration is subject to material types used in
plastic parts, accelerated when exposed to heat,
sun light, UV light or environmental factor.
Check the following before calling for servicing.
Symptom Check
Operation in HEAT/COOL mode is not
working efficiently.
• Set the temperature correctly.
• Close all doors and windows.
• Clean or replace the filters.
• Clear any obstruction at the air inlet and air outlet
vents.
Noisy during operation.
• Check if the unit has been installed at an incline.
• Close the front panel properly.
Remote control does not work.
(Display is dim or transmission signal is
weak.)
• Insert the batteries correctly.
• Replace weak batteries.
The unit does not work. • Check if the circuit breaker is tripped.
• Check if timers have been set.
The unit does not receive the signal from
the remote control.
• Make sure the receiver is not obstructed.
• Certain fluorescent lights may interfere with signal
transmitter. Please consult authorised dealer.

is normal to have the following temperature difference between the air inlet and outlet vents:
COOL: ≥8 °C / 14.4 °F HEAT: ≥14 °C / 25.2 °F
■The units are not going to be used for a long period of time
• Activate HEAT mode for 2~3 hours to remove moisture left in the internal parts thoroughly to
prevent mould growth.
• Turn off the power supply and unplug.
• Remove the remote control batteries.
NON SERVICEABLE CRITERIAS
