1. Disconnect the fixture from power and allow the components to cool completely.
2. Remove the covers, front lens and gobo modules 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. On each side of the head, remove the 2 screws that hold the side covers. Slide the covers forward to
remove. Clean the air filters or replace them. If they are saturated with smoke fluid, etcetera, soak them
in warm soapy water and blot dry. Position the filters on the side covers and reinstall. See Figure 18.
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 575 Krypton does not require lubrication under normal circumstances. The slides for the zoom
and focus lens cars are lubricated with a long-lasting teflon-based grease that can be reapplied by a Martin
service partner if necessary.
Fuse replacement
DANGER! Disconnect from power before opening covers. Replace fuses with ones of the same type
and rating only. Never bypass or bridge a fuse.
The MAC 575 Krypton is protected by a 10 amp slow blow main fuse located in a fuseholder next to the
power input connector on the connections plate.
To replace the main fuse:
1. Disconnect the power cable from the fixture at the power input connector.
2. Use a flathead screwdriver to open the fuseholder and remove the fuse for testing or replacement.
3. Replace defective fuses with ones of the same type and rating only. Replacement fuses are available
from Martin.
4. Reinstall the fuseholder before reapplying power.
A further 6.3 amp slow-blow fuse (P/N 05020020) is located on the power PCB. This fuse must be changed
by a qualified electrical technician observing appropriate safety and ESD (electrostatic discharge)
precautions.
