11 Cleaning
Clean the optical lenses, that are accessible from the outside, regularly in order to optimize the
light output. The frequency of cleaning depends on the operating environment: wet, smoky or
particularly dirty surroundings can cause more accumulation of dirt on the optics of the
device.
n Clean with a soft cloth using our lamp and lens cleaner (item no. 280122).
n
Always dry the parts carefully.
The fan grids of the device must be cleaned of any contamination, such as dust, etc. on a reg‐
ular basis. Before cleaning, switch off the device and disconnect mains-operated devices from
the mains. Only use pH-neutral, solvent-free and non-abrasive cleaning agents. Clean the unit
with a slightly damp lint-free cloth.
