Service And Maintenance; Cleaning - Martin Professional Stagebar 54 User Manual

Service and maintenance

Warning! Read "Safety Information" on page 3 before carrying out service or maintenance work on
the Stagebar 54. Lock out power to the entire distribution system before servicing, cleaning
or opening any cover. Refer any service operation not described here to a qualified service
technician.
Important! Excessive dust, smoke fluid, 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, the Stagebar 54's 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.
To maximize the life of the Stagebar 54 and protect the investment it represents, clean the fixture regularly
– especially the cooling fans and grilles – following the guidelines in this section.

Cleaning

Regular cleaning is essential 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 Stagebar 54. Cooling fans suck in airborne dust and
smoke particles, and in extreme cases fixtures may require cleaning after surprisingly few hours of
operation. Environmental factors that may result in a need for frequent cleaning include:
• Use of smoke or fog machines.
• High airflow rates (near air conditioning vents, for example).
• Presence of cigarette smoke.
• Airborne dust (from stage effects, building structures and fittings or the natural environment at outdoor
events, for example).
If one or more of these factors is present, inspect fixtures within their first 25 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.
Do not use abrasive, caustic or solvent-based products for cleaning, as they can damage plastic or painted
surfaces.
To clean the fixture:
1. Disconnect the fixture from power and allow it to cool for at least 10 minutes.
2. Vacuum or gently blow away dust and loose particles from the fan blades and grilles in the fixture's end
caps with compressed air.
3. Clean the diffuser front with a soft cloth dampened in a warm water/detergent solution.
4. If the lens sheets require cleaning, remove their retaining screws and wash them in a hot
water/detergent solution with a soft brush. Dry completely before reinstalling.
