Maintenance
Warning! Read 'Safety information' on page 6 before carrying out service or
maintenance. There are no user-serviceable parts inside. Do not open the
housing. Refer any service operation not described in this manual to Martin
Professional or its authorized service agents.
Installation, on-site service and maintenance can be provided worldwide by the Martin
Professional Global Service organization and its approved agents, giving owners
access to Martin's expertise and product knowledge in a partnership that will ensure
the highest level of performance throughout the product's lifetime. Please contact your
Martin® supplier for details.
Be aware that the output of LEDs, like all light sources, changes gradually over many thousands of
hours of use. If you require products to perform to very precise color specifications, you may
eventually need to make small readjustments at the lighting controller.
Cleaning
Regular cleaning is essential for fixture life and performance. Buildup of dust and dirt degrades the
fixture's light output and cooling ability.
Cleaning schedules will vary greatly depending on the operating environment. Inspect fixtures within
their first few months of operation to see whether cleaning is necessary. Check again at regular
intervals. This procedure will allow you to assess cleaning requirements in your particular situation.
Do not use products that contain solvents, abrasives or caustic agents for cleaning, as they can cause
surface damage to the fixture. The aluminum housing and front glass can be cleaned with mild
detergents such as those for washing cars.
To clean the housing and front glass:
1. Isolate the fixture from AC power and allow the fixture to cool for 20 minutes.
2. Visually check that the silicone seals and the power and data cables are in good condition. If any
seal or cable shows signs of damage, cracking or loss of water resistance, stop cleaning the
fixture and contact a Martin authorized service technician for replacement.
3. If seals are in good condition, rinse off loose dirt with a hose or low-pressure water spray.
4. Wash the aluminum housing and front glass using warm water with a little mild detergent and a
soft brush or sponge. Do not use abrasive cleaners.
5. Rinse with clean water and wipe dry.
Installation safety
Each time the fixture is cleaned, check that the fixture and any accessories mounted on it are held
securely and cannot fall. Check mounting fasteners and re-tighten if necessary.
Pressure relief valve
A valve with a gas-permeable membrane between the
cable entries on the back of the fixture (see illustration
on right) equalizes pressure by allowing air to pass
through it when the fixture heats up and cools down.
At the same time, the valve acts as a barrier to water
in liquid form. The expulsion of warm air (with a
slightly higher water vapor content) and intake of cool
air (with a slightly lower water vapor content) prevents
humidity buildup over time, provided that the valve
works correctly and that the fixture is correctly sealed.
Pressure relief valves have a limited service life. They become blocked over time as the micropores in
the membrane fill with particles. When a valve becomes blocked, excess pressure can damage seals
or cause air and even water to be sucked into the fixture along cables. A blocked valve cannot be
cleaned and must be replaced if it shows signs of contamination or is not in perfect condition. Valve
