Replacing The Head Air Filters - Martin MAC Viper Wash User Manual

If one or more of these factors is present, inspect fixtures within their first few hours of operation to see
whether cleaning is necessary. Check again at frequent intervals. This procedure will allow you to assess
cleaning requirements in your particular situation. If in doubt, consult your Martin dealer about a suitable
maintenance schedule.
Work in a clean, well lit area. Use gentle pressure only when cleaning. Do not use any product that contains
abrasives. Do not use solvents on plastic or painted surfaces. Use care when cleaning optical components:
the coated surfaces are fragile and easily scratched.
To clean the head:
1. Disconnect the fixture from power and allow it to cool for 30 minutes.
2. Remove the head covers (see "Access to the head" on page 16).
3. Vacuum or gently blow away dust and loose particles inside the head with compressed air.
4. Carefully clean the optical components, Remove smoke and other residues with cotton swabs or
unscented lens tissues moistened with isopropyl alcohol. A commercial glass cleaner may be used, but
residues must be removed with distilled water. Clean with a slow circular motion from center to edge.
Dry with a clean, soft, lint-free cloth or low-pressure compressed air. Remove stuck particles with an
unscented tissue or cotton swab moistened with glass cleaner or distilled water. Do not rub the surface:
lift the particles off with a soft repeated press.
5. Remove dust from fans and air vents with a soft brush, cotton swab, vacuum, or compressed air.
6. If you have finished work on the head, reinstall the head covers as described in "Access to the head" on
page 16 and release the tilt lock before reapplying power.

Replacing the head air filters

There are two disposable air filters in the MAC Viper Wash head. They must be replaced as a pair when
they become dirty.
The replacement procedure is the same for each air filter:
1. Disconnect the fixture from power and allow it to cool for 30 minutes.
2. Remove the head covers (see "Access to the head" on page 16).
3. See Figure 13. Loosen the two captive Torx 25 screws A at the front end of the filter housing until the
screws turn freely.
4. Disconnect the air filter fan connector B.
5. Slide the filter housing towards the front of the fixture to release the rear of the housing, then lift the
housing away from the head.
6. Press down on the two clips C until they release and you can open the filter housing.
