Safety precautions
WARNING
Precaution for appliance fi lled
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
fl oor area larger than A
and keep away from ignition
sources, such as heat/sparks/
open fl ame 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 A
Be aware that refrigerant may
not contain an odour, highly
recommended to ensure suitable
fl ammable 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 fl are nuts with the R32 and
R410A piping and fl are nuts on
the outdoor unit side.
The R32 fl are nut and pipe on
the outdoor unit side can also be
used for a R410A model.
min
(m²))
min
(m²)
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 fl ames 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 unfi t 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,
fl ame, sparks, or other sources
of ignition. Else it may explode
and cause injury or death.

equipment in front of the airfl ow
outlet to avoid fi re propagation.
Do not expose plants or pet
directly to airfl ow to avoid injury,
etc.
Do not touch the sharp
aluminium fi n, sharp parts
may cause injury.
Do not switch ON the indoor
unit when waxing the fl oor. 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.
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.
English
Safety precautions
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 ineffi cient power
usage and uncomfortable
temperature changes.
