Service and maintenance
Warning! Read “Safety Information” on page 3 before carrying out
service or maintenance work on the Extube. Lock out power to the
entire distribution system before servicing or opening any
cover.
Important! Excessive dirt and dust buildup degrades performance,
causes overheating and will damage the fixture. The Extube requires
cleaning at intervals that depend on the environment in which it is
installed. Damage caused by inadequate cleaning is not covered by
the product warranty.
The Extube, its power input cap with installed cable, and its end cap are
not user-serviceable. All service apart from cleaning, software renewal
and the installation work described in this manual 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 and environment, so it is impossible to specify
precise lifetimes for optical components. LEDs will eventually require
replacement 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. The expected lifetime (to 50% of
initial output level) of the Extube’s LEDs is minimum 20 000 hours at full
intensity.
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 Extube. 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.
