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 III 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.
Cleaning and replacing the air filters
The item AIR FILTERS in the FIXTURE INFORMATION menu is intended to be used to monitor intervals
between air filter cleaning, although this counter can be used to monitor any aspect of the fixture.
When air filters require cleaning:
1. Disconnect the fixture from power and allow
the components to cool for 2 hours 45
minutes.
2. See Figure 16. On each side of the head, use
a flat-bladed screwdriver to lever the front
edge of each filter holder slightly away from
the head, then slide the screwdriver across to
each corner and gently lever each corner
free. Pull the filter holders forwards to unclip
and remove them.
