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 authorised installer or service agent.
We recommend performing maintenance at least once a year. However, applicable
legislation might require shorter maintenance intervals.
