Instructions for safe operation
WARNING: MILDLY FLAMMABLE
MATERIAL
The refrigerant inside this unit is mildly
flammable.
WARNING
The appliance shall be stored so as to
prevent mechanical damage and in a
well-ventilated room without
continuously operating ignition sources
(example: open flames, an operating
gas appliance or an operating electric
heater).
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 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
Air purging heat emitters or
collectors.
Before you purge air from
heat emitters or collectors, check if
or
is displayed on the home screen
of the user interface.
▪ If not, you can purge air immediately.
▪ If yes, make sure that the room
where you want to purge air is
sufficiently ventilated.
Reason:
Refrigerant might leak into the water
circuit, and subsequently into the
room when you purge air from the
heat emitters or collectors.
