MAINTENANCE
The unit does not have any internal replaceable or adjustable components available to
the user. Pay attention to the ambient temperature in the room where the unit is operating.
Excessively high temperatures cause faster ageing of the internal components and shorten the
fault-free time of unit operation.
In cases where the unit gets dirty do not clean with solvents. For cleaning use soft, dry cloth.
In the case of more significant contamination use warm water with small amount of detergent
to wet the cloth.
Using any other agents can cause permanent damage to the housing.
Product marked with this symbol should not be placed in municipal waste. Please
