Service and maintenance
DANGER! Read “Safety Information” on page 3 before carrying out service or maintenance work on
the Exterior 400 Range. Lock out power to the entire distribution system before servicing or
opening any cover.
Important! The Exterior 400 Range requires regular service and maintenance to maintain reliable
operation and protect the investment it represents. 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.
Important! As with electronic components in general, Exterior 400 Range fixture PCBs are sensitive
to ESD (electrostatic discharge). Take precautions to avoid ESD damage during service.
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 must be carried out by the Martin
Service organization or its authorized agents.
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.
When installing front and rear covers, use a torque driver and cross-tighten screws (tighten screws opposite
each other gradually in steps, working around the cover). Tighten front and rear cover screws to 8 Nm (5.9
ft.-lbs.).
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 Range. 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 and
wiring during cleaning.
The Exterior 400 Range’s 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 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.
