Replacing a color filter
The MAC Viper AirFX has seven dichroic color filters. See the MAC Viper AirFX User Guide available for
download from www.martin.com for names and part numbers.
Use only genuine Martin™ color filters. Handle and store filters with care. Wear cotton gloves while handling
them and keep them perfectly clean.
To replace a color filter:
1. Disconnect the fixture from power and allow it to cool for 30 minutes.
2. Remove the head covers, position the head with the front glass angled downwards and the top side
facing upwards, and apply the tilt lock (see "Access to the head" on page 16).
3. Remove the projection module and open it for access (see "Access to projection effects" on page 19).
4. See Figure 24. Turn the color wheel A until the filter that you want to replace B is accessible from both
sides of the wheel. Put on clean cotton gloves and hold the filter near its outer edge between finger and
thumb. Pull the outer edge of the filter up from the color wheel slightly to release it, then slide the filter
carefully out of its clip and remove it. Store the filter resting on a clean, soft surface or in a filter rack.
5. To insert a color filter, first turn the filter so that
its coated side will face towards the lamp. To
find out which side of the filter is coated, hold
an object up against the glass. See Figure 25.
There will be a gap between the object and its
reflection on the uncoated side.
6. Slide the filter into its clip in the center of the
color wheel. Make sure that the outer edge of
the filter C locates under the lip on the edge of
the color wheel so that the filter is held
securely.
7. If no further service work is to be carried out,
reassemble and reinstall all removed
components with reference to the instructions
earlier in this section.
8. Release the tilt lock before applying power.
