Cleaning and replacing the air filters
The item AIR FILTERS in the FIXTURE INFORMATION menu is intended to be used to monitor intervals
between air filter cleaning, although this counter can be used to monitor any aspect of the fixture.
When air filters require cleaning:
1. Disconnect the fixture from power and allow
the components to cool for 2 hours 45
minutes.
2. See Figure 17. On each side of the head, use
a flat-bladed screwdriver to lever the front
edge of each filter holder slightly away from
the head, then slide the screwdriver across to
each corner and gently lever each corner
free. Pull the filter holders forwards to unclip
and remove them.
3. See Figure 18. On each side of the base, pinch the air filter
holders in from the sides as illustrated, then pull the center of
the holders outwards to unclip and remove them.
4. Clean the air filter elements. If they are saturated with smoke
fluid, soak them in warm, soapy water and blot dry. If the filters
cannot be cleaned completely or are not in perfect condition,
replace them with new items.
5. Pinch the base filter holders in from the side and engage the
ends of the filter holders their slots to clip them back into
position.
6. See Figure 19. Engage the three tabs in the head filter
holders in their slots in the head, pinch the foremost corners
of the filter holder together slightly and press them into the
head to clip them back into position.
7. Check that all filter holders are correctly installed so that there
is an airtight seal around all their edges.
