Routine maintenance 35
R OUTINE MAINTENANCE
Warning! Disconnect the fixture from power and allow to cool before removing any cover.
Important! Excessive dust, smoke fluid, and particulate buildup degrades performance and causes
overheating and damage to the fixture that is not covered by the warranty.
The MAC 2000 Performance II requires routine cleaning. To maximize the life of the product and protect the
investment it represents, clean the fixture regularly – especially the cooling systems. It is essential to follow
the guidelines given later in this section.
Refer any service operation that is not described here to a qualified Martin technician.
It is Martin policy to use the best-quality materials and coatings 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 of dichroic
filters or the specular properties of reflectors, 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
optical components 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.
Lamp
The MAC 2000 Performance II is supplied with a Philips
MSR 1200 SA/DE GOLD 1200 W discharge lamp installed.
This source has a color temperature of 6000 K, a color
rendering index greater than 85, and an average life of 750
hours.
The lamp is capable of hot restrike. This feature, however,
is only supported by the MAC 2000 Performance II with
electronic ballast.
The ends of the lamp are profiled with special keys, as
shown in Figure 11, to ensure proper installation. Do not
use lamps with keys in a non-keyed SFc 10-4 socket.
Warning! Install only an approved lamp (see “Source” on
page 55). Installing any other lamp may create a
safety hazard or damage the fixture!
The lamp should be replaced when it has reached the limit
of its 750 hour average life. To reduce the risk of explosion,
never exceed 125% of the lamp’s average life, i.e. 940
hours. To read lamp hours from the control panel, please
refer to “Readouts” on page 14.
For optimum performance, avoid turning off the lamp before
it has warmed up fully.
