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).
NOTICE
Maintenance MUST be done by an authorized installer or
service agent.
We recommend performing maintenance at least once a
year. However, applicable legislation might require shorter
maintenance intervals.
