Cleaning - Martin Professional MAC 2000 Performance II User Manual

A l i g n i n g t h e l a m p
1 Switch on the MAC 2000 Performance II and allow it to
reset. Using either a controller or the control module, turn
on the lamp and project an open white beam on a flat
surface.
2 Center the hot spot vertically using the top Allen-head
adjustment screw in the center of the rear plate.
3 If there is significant hot spot, turn the bottom adjustment
screw counterclockwise until the light is evenly distributed.
If the light is brighter around the edge than it is in the
center, or if light output is low, turn the bottom adjustment
screw clockwise until the light is bright and evenly
distributed.
4 Repeat step 2.

Cleaning

Regular cleaning is very important for fixture life and performance. Buildup of dust, dirt, smoke particles, fog fluid
residues, etc. degrades the fixture's light output and cooling ability.
Cleaning schedules for lighting fixtures vary greatly depending on the operating environment. It is therefore
impossible to specify precise cleaning intervals for the MAC 2000 Performance II. Cooling fans suck in airborne dust
and smoke particles, and in extreme cases fixtures may require cleaning after surprisingly few hours of operation.
Environmental factors that may result in a need for frequent cleaning include:
• Use of smoke or fog machines.
• High airflow rates (near air conditioning vents, for example).
• Presence of cigarette smoke.
• Airborne dust (from stage effects, building structures and fittings or the natural environment at outdoor events, for
example).
If one or more of these factors is present, inspect fixtures within their first 25 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.
Use care when cleaning optical components and work in a clean, well lit area. The coated surfaces are fragile and
easily scratched. Do not use solvents that can damage plastic or painted surfaces.
To maintain adequate cooling, dust must be cleaned from the fans and air vents periodically. Inspect the air filters
regularly and clean before they become clogged. Replace the air filters with new ones when replacing the lamp.

1 Disconnect the fixture from power and allow the components to cool completely. Remove the head cover.
2 Vacuum or gently blow away dust and loose particles with compressed air.
3 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.
4 Remove smoke and other residues with cotton swabs or unscented 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 and lint-free cloth or compressed air.
C l e a n i n g t h e f a n a n d a i r v e n t s
Remove dust from the fans and air vents with a soft brush, cotton swab, vacuum, or compressed air.
