Safety Precautions
WARNING
This appliance is fi lled with
R32
(mild fl ammable refrigerant).
If the refrigerant is leaked and
exposed to an external ignition
source, there is a risk of fi re.
Indoor unit and outdoor unit
The appliance shall be installed, and/
or operated in a room with fl oor area
larger than A
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 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.
Keep any required ventilation
openings clear of obstruction.
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.

Precaution for using R32
refrigerant
The basic installation work procedures are
the same as conventional refrigerant (R410A,
R22) models.
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.
For R32 and R410A, the same fl are
nut on the outdoor unit side and pipe
can be used.
The mixing of different refrigerants
within a system is prohibited. 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 1/2 inch.]
Must always ensure 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.)
• Operation, maintenance, repairing
and refrigerant recovery should be
carried out by trained and certifi ed
personnel in the use of fl ammable
refrigerants and as recommended
by the manufacturer. Any personnel
conducting an operation, servicing
or maintenance on a system or
associated parts of the equipment
should be trained and certifi ed.
