Removing And Reinstalling The Top Cover - Martin Exterior Projection 500 User Manual

Removing and reinstalling the top cover

Important! Open the fixture in dry weather conditions only. Use Evaporation Mode as described
below and a new silica gel desiccant bag to avoid humidity inside the fixture.
Access to optical components is made easy by a cover on the top of the fixture.
Removing the top cover
To remove the top cover:
1. Disconnect the fixture from power and allow it to cool for at least 60 minutes.
2. See illustrations below. Use a 5 mm Allen key (hex wrench) to remove the four top cover
screws (arrowed). Lift the top cover off the fixture. For ease of access – and if it is safe to do
so – you can unclip the safety cable and remove the cover completely from the fixture.
Reinstalling the top cover
To reinstall the top cover:
1. See illustration on right. Check the silicone
seal in the top cover. If it is not in perfect
condition, replace it with a new item from
Martin.
2. If you unclipped the top cover safety cable,
reinstall the safety cable so that it will catch
the top cover and prevent it from falling while
screws are loosened.
3. Place the top cover loosely over the top of
the fixture so that air can enter and leave the
fixture.
