7. Unlock the gobo module by pulling the levers on each side towards the center. Lift the module up 1 cm

(0.5 in.) and release the levers. Lift the module straight up to remove from the head.

8. When reinstalling the module, verify that the guide pins are correctly seated and that the module is

securely locked.

To remove the dimmer module

The dimmer module can be removed

for service and to access the lamp

cooling fans and heat shield:

1. Remove the gobo module as

described above.

2. Like the gobo module, the smaller

dimmer module is also released by

pulling on two levers. Lift the

module straight up to remove from

the head.

3. When reinstalling, verify that the

guide pins are correctly seated and

that the module is securely locked.

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 550 Profile. 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 all fixtures within their first 24 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. Experience and consultation with your Martin service

representative will help you determine an appropriate maintenance schedule.

Use care when cleaning optical components and work in a clean, well lit area. The coated surfaces are

fragile and easily scratched. Do not use solvents that can damage plastic or painted surfaces.

To clean the fixture

1. Disconnect the fixture from power and allow the components to cool completely.

2. Remove the covers, front lens and gobo and dimmer modules as described earlier.

3. Vacuum or gently blow away dust and loose particles with compressed air.
