to the specified torque will compress seals too much.
• Air and water can be sucked along cables and into fixtures. A cracked or porous cable jacket can
allow water into the cable. Replace any cable that is not in perfect condition. Make sure that cables
from fixtures open into dry areas (e.g. junction boxes in dry locations).
• Do not clean fixtures with high-pressure water jets or immerse them.
Anti-humidity bag
The fixture is supplied with an anti-
humidity bag installed inside it to
absorb moisture. Each time the
fixture is opened, this bag must be
removed and a new bag from Martin
installed in its place.
To install a new bag, see photo on
right. Open the clip on the bag
holder in the effects compartment
cover, replace the anti-humidity bag
with a new item and close the clip
over the new bag.
Drying off function
A small amount of condensation behind the front glass is normal under certain temperature conditions,
but excess moisture can be cleared using the fixture's drying off function.
Important! Carry out the following operation with the fixture in dry conditions only.
To run the drying off sequence:
1. Open the effects compartment cover as described in 'Opening and closing the fixture' later in this
chapter.
2. Replace the anti-humidity bag in the cover with a new bag (see instructions above).
3. Enable the Dry off function via RDM or the DMX Control / Settings channel, leaving the effects
compartment cover open so that air can circulate.
4. Allow the procedure to run for approximately 15 minutes, then stop the Dry off function.
5. Re-install the effects compartment cover as described later in this chapter.
Seals and sealing surfaces
The fixture must be sealed effectively. Covers have silicone seals that will withstand rain and water
splashing but will not withstand immersion or high-pressure water jets. Reinstall covers and seals
carefully if you have removed them.
• Make sure that seals and sealing surfaces are perfectly clean, dry and in perfect condition before
installing a cover. If you need to clean seals, use water and a soft cloth only. Replace any seal that
shows signs of aging, damage, cracking, stretching or deformation. Replacement seals are
available from Martin.
• Reinstall seals in exactly their original position.
• Install seals so that they closely follow the profile of the metal parts they are installed on. When you
run your finger around the sealing surface after you have installed a cover, you should not be able
to feel any places where the seal sticks out or sinks into the gap between the sealing surfaces.
• Do not use liquid gasket or any other type of sealant on sealing surfaces or seals.
