5. Unlock the main module by pulling the levers
on each side towards the center. Lift the
module up 1 cm (0.5 in.) and release the
levers. Lift the module straight up to remove
from the head.
6. When reinstalling the module, verify that the
guide pins are correctly seated and that the
module is securely locked.
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 700 Wash. 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
1. Disconnect the fixture from power and allow the components to cool completely.
2. Remove the covers, front lens and main 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.
5. Remove dust from the head fans and air vents with a soft brush, cotton swab, vacuum, or compressed
air.
6. See Figure 12. On each side of the head, remove the 2 screws that hold the side covers and slide the
covers forward to remove. Unscrew the air filter clips and inspect the filter elements. If they are dirty,
soak them in warm soapy water and blot dry. If the filters are not in perfect condition, replace them.
Reinstall the filters and side covers.
7. Reassemble the head.
8. Remove the screws from the side cover/grill on the front of the base (front is indicated by an arrow on
the bottom). Remove the top cover from the front of the base. Lift the power supply / ballast module up
and out to expose the base fans for inspection and cleaning.
9. Reinstall the power supply / ballast module and base cover.
Lubrication
The MAC 700 Wash does not require lubrication under normal circumstances. Sliding parts are lubricated
with a long-lasting teflon-based grease that can be reapplied by a Martin service partner if necessary.
