9.3 About the refrigerant
This product contains refrigerant gases.
Refrigerant type: R744 (CO
2
)
WARNING
▪
Do NOT pierce or burn refrigerant cycle parts.
▪
Be aware that the refrigerant inside the system is odourless.
WARNING
The R744 refrigerant (CO
2
) inside the unit is odourless, non-flammable and normally
does NOT leak.
If the unit is installed indoors, ALWAYS install a CO
2
detector according to the
specifications of standard EN378.
If the refrigerant leaks in high concentrations in the room, it may have negative
effects on its occupants such as asphyxiation and carbon dioxide poisoning. 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.
9.4 Recommended maintenance and inspection
Since dust collects when using the unit for several years, performance of the unit
will deteriorate to some extent. As taking apart and cleaning interiors of units
requires technical expertise and in order to ensure the best possible maintenance
of your units, we recommend to enter into a maintenance and inspection contract
on top of normal maintenance activities. Our network of dealers has access to a
permanent stock of essential components in order to keep your unit in operation
as long as possible. Contact your dealer for more information.
When asking your dealer for an intervention, always state:
▪
The complete model name of the unit.
