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.

ventilated room without continuously operating ignition sources (e.g. open flames,

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.
