Split system air conditioner

WARNING
The appliance using R32 refrigerant
shall be stored so as to prevent
mechanical damage and in a well-
ventilated room without continuously
operating ignition sources (e.g. open
flames, an operating gas appliance, or
an operating electric heater). The room
size shall be as specified in the
General safety precaution.
WARNING
▪ Do NOT pierce or burn refrigerant
cycle parts.
▪ Do NOT use cleaning materials or
means to accelerate the defrosting
process other than those
recommended by the manufacturer.
▪ Be aware that the refrigerant inside
the system is odourless.
WARNING
R410A is a non-combustible
refrigerant, and R32 is a mildly
flammable refrigerant; they normally
don’t leak. If the refrigerant leaks in the
room and comes into contact with fire
from a burner, a heater, or a cooker,
this may result in a fire (in case of
R32), or the formation of a harmful gas.
Turn off any combustible heating
devices, ventilate the room, and
contact the dealer from where you
purchased the unit.
Do not use the unit until a service
person confirms that the part from
which the refrigerant leaked has been
repaired.
Troubleshooting (see
11])
WARNING
Stop operation and shut off the
power if anything unusual occurs
(burning smells etc.).
Leaving the unit running under such
circumstances may cause breakage,
electric shock or fire. Contact your
dealer.

About the system
WARNING
▪ Do NOT modify, disassemble, remove, reinstall or
repair the unit yourself as incorrect dismantling or
installation may cause an electric shock or fire. Contact
your dealer.
▪ In case of accidental refrigerant leaks, make sure there
are no naked flames. The refrigerant itself is entirely
safe and non-toxic. R410A is a non-combustible
refrigerant, and R32 is a mildly flammable refrigerant,
but they will generate a toxic gas when they
accidentally leak into a room where combustible air
from fan heaters, gas cookers, etc. is present. Always
have qualified service personnel confirm that the point
of leakage has been repaired or corrected before
resuming operation.
NOTICE
Do NOT use the system for other purposes. In order to
avoid any quality deterioration, do NOT use the unit for
cooling precision instruments, food, plants, animals, or
works of art.
NOTICE
For future modifications or expansions of your system:
A full overview of allowable combinations (for future
system extensions) is available in technical engineering
data and should be consulted. Contact your installer to
receive more information and professional advice.
