Safety precautions
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.
Precaution for using R32 refrigerant
Pay careful attention to the following points
when operating the appliances and dealing
with different refrigerants.
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.
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 more careful than R22 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
