Service and maintenance
Warning! Read “Safety Information” on page 3 before carrying out service or maintenance work on
the Exterior 400 Image Projector.
Danger! Lock out power to the entire distribution system before servicing or opening any cover.
Warning! The service and maintenance procedures described in this section must be carried out by
qualified professionals only. Any service procedures not described in this section may be carried
out only by the Martin Service organization or its authorized agents.
Important! The Exterior 400 Image Projector requires occasional service and maintenance to
maintain reliable operation and protect the investment it represents. It also requires a cleaning
schedule that is appropriate for the environment it is used in. Excessive dirt and particle buildup
degrades performance, causes overheating and will damage the fixture. Damage caused by
inadequate cleaning or maintenance is not covered by the product warranty.
As with electronic components in general, Exterior 400 Image Projector fixture PCBs are sensitive
to ESD (electrostatic discharge). Take precautions to avoid ESD damage during service.
It is Martin policy to use the best quality materials available to ensure optimum performance and the longest
possible component lifetimes. However, optical components in all lighting fixtures are subject to wear and
tear over the life of the fixture, resulting in gradual changes in color rendition, for example. The extent of
wear and tear depends heavily on operating conditions, maintenance and environment, so it is impossible
to specify precise lifetimes for optical components. However, you will eventually need to replace LEDs if
their characteristics are affected by wear and tear after an extended period of use and if you require fixtures
to perform within very precise optical and color parameters.
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. It is therefore impossible to
specify precise cleaning intervals for the Exterior 400 Image Projector. Inspect fixtures within their first few
weeks 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. If in doubt, consult your Martin
dealer about a suitable maintenance schedule.
Do not use products that contain solvents, abrasives or caustic agents for cleaning, as they can cause
surface damage to the fixture.
Warning! Do not use a high-pressure water jet for cleaning. Take care not to damage seals, cables
and cable glands during cleaning.
The Exterior 400 Image Projector’s aluminum housing and front glass can be cleaned with a mild detergent
such as a car wash shampoo solution. To clean the housing and front glass:
1. Isolate the fixture from AC power and allow the fixture to cool for 30 minutes.
2. Visually check that the silicone seals between joints in the housing are in good condition. If any seal
shows signs of damage or loss of water resistance, stop cleaning the fixture and contact a Martin
authorized service technician for seal replacement.
3. If seals are in good condition, rinse off loose dirt with a hosepipe or low-pressure water spray. Do not
spray water into the heat exchanger.
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.
