11. Maintenance and cleaning
It is absolutely essential that the xture is kept clean and that dust, dirt and smoke-uid residues must not build
up on or within the xture. Otherwise, the xture‘s light-output will be signicantly reduced. Regular cleaning will
not only ensure the maximum light-output, but will also allow the xture to function reliably throughout its life.
DANGER !
Disconnect from the mains before starting any
maintenance and cleaning work
The outer side of the front optical module should be cleaned monthly by means of a vacuum cleaner as dust
reducing the light-output very quickly. The cooling fans should be cleaned at least twice a year.
The interior of the xture should be cleaned at least annually using a vacuum cleaner or an air-jet.
Important! Check the air lter periodically and clean before they become
clogged!
Periodically clean air lter placed in the xture´s base. The air lter cover is fastened by means of magnets.
Use a vacuum cleaner, compressed air or you can wash them and put back dry.
After replacing the air lters, reset the elapsed time counter in the menu "Information" (Information--->Air Fil-
ters---> Elapsed Time).
Replacing the fuse.
Before replacing the fuse, unplug mains lead.
1) Remove the fuse holder on the rear panel of the base with a tting screwdriver from the housing
(anti-clockwise).
2) Remove the old fuse from the fuse holder.
3) Install the new fuse in the fuse holder (only the same type and rating).
4) Replace the fuseholder in the housing and x it.
