MAC Viper AirFX Safety and Installation Guide
Lubrication
The MAC Viper AirFX 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.
Access to the head
Warning! Disconnect from power and allow to cool for 30 minutes before opening the head.
To open the head:
1. Disconnect the fixture from power, allow components to cool for 30 minutes.
2. For easiest access to the components inside the head, position the head with the top facing upwards (in
this position the text on the lamp cover is the right way up) at an angle with the front facing downwards,
then apply the tilt lock.
3. See Figure 12. Remove both head covers by loosening their Torx 25 captive retaining screws
A
until the
screws turn freely. Lift the front of each cover slightly away from the head, then slide the cover towards
the front of the head to release the rear of the cover.
4. You can allow head covers to hang on their safety wires, but for easiest access press each cover’s safety
wire retaining clip
B
in towards the head chassis, slide the clip until you can remove it, then remove the
head cover completely from the fixture.
To reinstall the head covers:
1. See Figure 12. Hold each cover up to the head and fasten its safety wire retaining clip
B
into the head
chassis by pressing the clip through its hole and then sliding it until it is held securely.
2. Slide the rear of the cover towards the back of the head until its retaining clips locate, then swing the
front of the cover in towards the head and fully tighten each cover’s two Torx 25 retaining screws. Check
that each cover is securely attached.
3. Release the tilt lock before applying power or packing the MAC Viper AirFX in its flightcase.
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 Viper AirFX. 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).
