a) Cleaning
Never use any aggressive cleaning agents, cleaning alcohol or other chemical solutions for outer cleaning,
since these may damage the casing or even impair function.
Disconnect the device from the power supply and leave it to cool down before cleaning.
• The device is maintenance-free and you should therefore never open it. If you open it, the guarantee will expire.
• The housing can be cleaned with a moist cloth on the outside.
• In particular clean the area of the fog exit (3) regularly.

If it becomes necessary to replace a fuse, make sure that only fuses of the prescribed type and nominal current are
used(see“TechnicalData”).
Never repair fuses or bridge the fuse holder.
• Unplug the mains adapter from the mains socket.
• Use a suitable screwdriver to carefully screw the fuse holder FUSE next to the mains switch with the defective fuse
from the back of the device.
• Remove the defective fuse and replace it with a new fuse of the indicated type.
• Now carefully screw in the fuse holder FUSE with the new fuse.
• After this, you can reconnect the device to the mains and take it into operation.
