Cleaning - Martin MAC TW1 User Manual

To remove the effects module:
1. Remove the four retaining screws from the front lens ring (see Figure 11) and remove the front lens.
2. Remove the two retaining screws on the outside edges of the module to release it.
3. Loosen the screws in the two module wireset connectors as shown in Figure 11 before lifting the module
away from the fixture.
When reinstalling the effects module, check that the guide pins are correctly seated, that the module is
securely screwed into position and that the screws in the two cable connectors are tight. The module is fitted
with LEDs that light to indicate that the CMY filters are in their correct positions.

Cleaning

Regular cleaning is essential 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 TW1. 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 clean the fixture
Warning! Disconnect from power and allow to cool before cleaning.
1. Disconnect the fixture from power and allow it to cool for at least 45 minutes.
2. Remove the covers and CMY module as described earlier.
3. Vacuum or gently blow away dust and loose particles with compressed air.
4. Carefully clean the optical components. 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. 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.
