Replacing The Head Air Filters - Martin MAC Quantum Profile Safety And Installation Manual

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.
Work in a clean, well lit area. Use gentle pressure only when cleaning. Do not use any product that contains
abrasives. Do not use solvents. Use care when cleaning optical components: surfaces are fragile and easily
scratched.
To clean the fixture:
1. Disconnect the fixture from power and allow it to cool for at least 30 minutes.
2. Vacuum or gently blow away dust and loose particles from the outside of the fixture and air vents with
low-pressure compressed air.
3. Clean the front glass on the front of the head by wiping gently with a soft, clean, lint-free cloth moistened
with a weak detergent solution.
4. If you need to clean glass optical components, follow the instructions in "Servicing optical components"
on page 14. Do not rub surfaces 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.
5. Check that the fixture is dry and correctly assembled before reapplying power.

Replacing the head air filters

Free airflow through air filters is important for effective cooling and maximized performance and product life.
Air filters will therefore require periodical replacement. As with cleaning, air filter replacement intervals
depend on the environment the fixture is used in. Inspect air filters visually at regular intervals and replace
them if filters are visibly contaminated by dust, dirt, residue from atmospheric effects, etc.
Air filters for the MAC Quantum Profile are disposable items that must be replaced, not cleaned. New filters
are available from Martin™ suppliers by ordering P/N 50400765 'Head air filter, MAC Quantum Profile, set
of 12'. Two filters are required per fixture.
To service the head air filters:
1. Disconnect the fixture from power and allow components to cool for 30 minutes.
2. Position the head so that the air filter covers are accessible and apply the tilt lock (see Figure 1 on page
6).
3. See Figure 8. On both sides of the head, unclip the air filter covers and lift them off the head.
