Replacing The Lamp Socket; Cleaning - Martin MAC 2000 Wash User Manual

Aligning the lamp
To align the lamp:
1 Switch on the MAC 2000 Wash 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 a 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.

Replacing the lamp socket

The lamp holder used in the MAC 2000 Wash eventually wears out due to the high voltages that pass
through the contacts. Service life will vary, but as a rule you should plan to replace the holder every 4000
hours approximately.
Wear begins to show up as discoloration at the contact surfaces. When this happens, resistance increases
and the lamp becomes harder to strike. If this process is allowed to continue, the lamp is likely to fail
prematurely.
Each time the lamp is replaced, inspect the lamp holder and have it replaced by a qualified technician as
soon as there are signs of discoloration or pitting at the contact surfaces. Damage caused by failure to
replace a worn and/or discolored lamp holder is not covered by the product warranty.

Cleaning

The MAC 2000 Wash requires routine cleaning. The schedule depends heavily on the operating
environment; please consult a Martin service technician for recommendations.
Important! Excessive dust, smoke fluid, and particle buildup degrades performance, leads to
overheating and causes damage to the fixture that is not covered by the warranty.
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.
Inspect the air filters regularly and clean before they become clogged. Replace the air filters with new ones
when replacing the lamp.
To maintain adequate cooling, dust must be cleaned from the fans and air vents periodically.
Optical components
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.
Fan and air vents
Remove dust from the fans and air vents with a soft brush, cotton swab, vacuum, or compressed air.
