3 | User safety instructions
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, non-toxic and mildly flammable, but it will
generate toxic gas when it accidentally leaks 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.
CAUTION
ALWAYS use a user interface to adjust the position of the
flaps and louvers. When the flaps and louvers are swinging
and you move them forcibly by hand, the mechanism will
break.
CAUTION
NEVER expose little children, plants or animals directly to
the airflow.
WARNING
Do NOT place objects below the indoor and/or outdoor
unit that may get wet. Otherwise condensation on the unit
or refrigerant pipes, air filter dirt or drain blockage may
cause dripping, and objects under the unit may get dirty or
damaged.
WARNING
Do NOT place a flammable spray bottle near the air
conditioner and do NOT use sprays near the unit. Doing so
may result in a fire.
CAUTION
Do NOT operate the system when using a room
fumigation-type insecticide. Chemicals could collect in the
unit, and endanger the health of people who are
hypersensitive to chemicals.

WARNING
The refrigerant inside the unit is mildly flammable, but
normally does NOT leak. If the refrigerant leaks in the
room and comes in contact with fire from a burner, a
heater, or a cooker, this may result in fire, or the formation
of a harmful gas.
Turn off any combustible heating devices, ventilate the
room, and contact the dealer 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.
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
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
DANGER: RISK OF ELECTROCUTION
To clean the air conditioner or air filter, be sure to stop
operation and turn all power supplies off. Otherwise, an
electric shock and injury may result.
CAUTION
After a long use, check the unit stand and fitting for
damage. If damaged, the unit may fall and result in injury.

breaker off or pull out the supply cord. Otherwise, an
electric shock and injury may result.
WARNING
Stop operation and shut off the power if anything
unusual occurs (burning smells etc.).
