Cleaning
Regular cleaning is very important for fixture life and performance. Buildup of dust, dirt, smoke particles, fog
fluid residues, etc. degrades the fixture’s light output and cooling ability.
Cleaning schedules for lighting fixtures vary greatly depending on the operating environment. It is therefore
impossible to specify precise cleaning intervals for the ERA 500 Hybrid IP. In extreme cases fixtures may
require cleaning after surprisingly few hours of operation. Inspect fixtures within their first few hours 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.
Follow these precautions when cleaning the fixture:
• Work in dry, well-lit conditions.
• Use gentle pressure only. Do not use any product that contains abrasives. Do not use solvents. Use care
when cleaning optical components: avoid scratching surfaces.
• Do not spray the fixture with a high-pressure water jet or you may damage seals.
• Use a vacuum cleaner – do not use a high-pressure air jet. A vacuum cleaner will remove dirt from the
fixture and from the area where you are working. An air jet may damage a seal, reducing the fixture’s
protection against the entry of water and dirt.
Cleaning procedure
To clean the fixture:
1. Disconnect the fixture from power and allow it to cool for at least 60 minutes.
2. Vacuum dust and loose particles from the outside of the fixture, especially the fan cover on the back of
the head and the cooling ribs, using a soft brush to help dislodge dust.
3. Clean the front glass on the front of the head by wiping gently with a soft, clean, lint-free cloth moistened
with a weak detergent solution. Do not rub the surface hard: lift particles off with a soft repeated press.
Dry with a soft, clean, lint-free cloth or low-pressure compressed air. Remove stuck particles with an
unscented tissue or cotton swab moistened with glass cleaner or distilled water.
4. If the fixture’s other outer surfaces are oily, wipe clean with a soft cloth and detergent solution. Do not
spray any part of the fixture with high-pressure water jets.
Lubrication
The ERA 500 Hybrid IP does not require lubrication under normal circumstances. Moving parts can be
checked and a long-lasting Teflon-based grease reapplied by a Martin service partner if necessary.
Lamp
Warning! Read “Lamp safety” on page 5 before replacing or adjusting the lamp.
If the bulb of a discharge lamp breaks, the lamp releases a small amount of harmful mercury vapor.
If the lamp has exploded or broken inside the ERA 500 Hybrid IP, that vapor will be trapped inside
the fixture. If the lamp in a fixture stops working, assume that the bulb has broken and follow the
safety precautions given under “Lamp safety” on page 5.
The ERA 500 Hybrid IP is designed for use with a 370 W Philips MSD Platinum 18 R LL discharge lamp. Do
not install any lamp in the fixture that is not specifically approved by Martin for use in the ERA 500 Hybrid IP.
Lamp life
The Philips MSD Platinum 18 R LL lamp has an average service life of 1500 hours of constant use.
However, in practice the service life of the lamp can be up to 6000 hours depending on how the lamp is
used. If the fixture is dimmed to blackout for extended periods, for example, lamp life will be extended
significantly.
Monitor lamp hours using the resettable lamp lifetime counter in the
INFORMATION
control menu. The
fixture will also give a warning in its control panel display when it reaches 80%, 90% and 100% of its service
life.
