Maintenance
Read the user manual before performing service or
maintenance on the product.
Failure to respect service and maintenance schedules
may cause damage that is not covered by product
warranties.
Cleaning the product
Regular cleaning is very important for xture life and
performance. Buildup of dust, dirt, smoke particles, fog
uid residures, etc. degrades the xture’s light output
and cooling ability. Cleaning schedules for lighting
xtures can vary greatly depending on the operating
environment. Cooling fans suck in airborne dust
and smoke particles, and in extreme cases xtures
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 airow rates (near air conditionning vents, for
example)
• Presence of cigarette smoke. Airborne dust (from
stage effects, building struktures and ttings or
the natural environment at outdoor events, for
example)
If one or more of these factors is present, inspect
xtures within their rst 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
®
by Harman dealer about a
suitable maintenance schedule.
Work in a clean, well lit area. Use gentle pressure
only when cleaning. Do not use any product that
contains abrasives. Use care when cleaning optical
components: the coated surfaces are fragile and easily
scratched.
