MAC Ultra Performance Safety and Installation Manual
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 Ultra Performance. 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 few 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.
Follow these precautions when cleaning the fixture:
• Work in a clean, dry, well-lit area.
• Use gentle pressure only. Do not use any product that contains abrasives. Do not use solvents. Use care
when cleaning optical components: surfaces are fragile and easily scratched.
• Use a vacuum cleaner – do not use a pressurized air jet. A vacuum cleaner will remove dirt from the
fixture and from the area where you are working. An air jet may blow dirt into the fixture, and this can
cause visible objects in projections and possibly even damage to the fixture.
• Do not apply a strong vacuum directly to a cooling fan, as the strong airflow may spin the fan blades fast
enough to cause damage. Instead, hold the vacuum cleaner nozzle a few centimeters away from the fan
and dislodge dust with a soft brush.
Cleaning procedure
To clean the fixture:
1. Disconnect the fixture from power and allow it to cool for at least 30 minutes.
2. Vacuum dust and loose particles from the outside of the fixture and the air vents at the back and sides of
the head and in the base, using a soft brush to help dislodge dust.
3. Clean the front lens on the front of the head by wiping gently with a soft, clean, lint-free cloth moistened
with a weak detergent solution. Do not rub the surface hard: lift particles off with a soft repeated press.
Dry with a soft, clean, lint-free cloth or low-pressure compressed air. Remove stuck particles with an
unscented tissue or cotton swab moistened with glass cleaner or distilled water.
4. Check that the fixture is dry before reapplying power.
Battery replacement
Warning!
Disconnect the fixture from AC power before replacing its battery. Do not attempt to recharge the
battery, or you may create a risk of fire or explosion. Replace the battery with one of the same type
only. New batteries are available from Martin (P/N 05801011).
The MAC Ultra Performance has
a non-rechargeable CR123A
3-volt lithium battery that
provides power to the control
panel and display when the
fixture is not connected to AC
mains power. If the battery runs
flat you must replace it with a
new one. Do not attempt to
recharge it.
