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.
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.

CAUTION
Indoor unit and outdoor unit
Do not wash the indoor unit
with water, benzine, thinner
or scouring powder to avoid
damage or corrosion at the unit.
Do not use for preservation
of precise equipment, food,
animals, plants, artwork or other
objects. This may cause quality
deterioration, etc.
Do not use any combustible
equipment in front of the airflow
outlet to avoid fire propagation.
Do not expose plants or pet
directly to airflow to avoid injury,
etc.
Do not touch the sharp
aluminium fin, sharp parts
may cause injury.
Do not switch ON the indoor
unit when waxing the floor. After
waxing, aerate the room properly
before operating the unit.
Do not install the unit in oily and
smoky areas to prevent damage
to the unit.
Do not dismantle the unit for
cleaning purpose to avoid injury.
Do not step onto an unstable
bench when cleaning the unit to
avoid injury.
Do not place a vase or water
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.
Safety precautions
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.

The following symptoms do not indicate malfunction.
Symptom Cause
Mist emerges from indoor unit. • Condensation effect due to cooling process.
Water flowing sound during operation. • Refrigerant flow inside the unit.
The room has a peculiar odour. • This may be due to damp smell emitted by the wall,
carpet, furniture or clothing.
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).
Operation is delayed a few minutes after
restarting. • The delay is a protection to the unit’s compressor.
Outdoor unit emits water/steam. • Condensation or evaporation occurs on pipes.
TIMER indicator is always on. • The timer setting repeats daily once set.
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).
Indoor fan stops occasionally during heating
operation. • To avoid unintended cooling effect.
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.
Cracking sound during operation. • Changes of temperature caused the expansion/
contraction of the unit.
Dusts accumulated on the wall. • Due to air circulation or static electricity generated
by the air conditioner. Some types of wall paper may
collect dusts easily (recommended to clean the area
around the air conditioner frequently).
During COOL/DRY mode, the indoor unit
stops and POWER indicator blinks. • The system has locked to operate in HEAT model only.
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.
Cooling/heating capacity reduced during the
lowest fan speed setting. • The low fan speed is low noise priority operation, so cooling/heating capacity may be reduced (depending
on the condition). Increase the Fan Speed to increase
the capacity.
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.
