Removing and reinstalling the top cover
Important! Open the fixture in dry weather conditions only. Use the fixture’s Evaporation Mode
and a new silica gel desiccant bag when you close the fixture to reduce 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 illustration on right. Use a 5 mm Allen key
(hex wrench) to remove the eight 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.
