3 About the system
(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.
