Service And Maintenance; Tilt Lock; Disassembly - Martin MAC 575 Krypton User Manual

Service and maintenance

Warning! Read "Safety Information" on page 3 before servicing the MAC 575 Krypton. Disconnect
the fixture from power and allow to cool for 45 minutes before handling or removing 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.
As with electronic components in general, the MAC 575 Krypton's PCBs are sensitive to ESD
(electrostatic discharge). Take precautions to avoid ESD damage before opening the fixture. Service
electronic components at a static-safe workstation only.
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.
To maximize the life of the MAC 575 Krypton and protect the investment it represents, clean the fixture
regularly – especially the cooling systems – following the guidelines in this section.

Tilt lock

Important! Release the tilt lock before operating the fixture.
The tilt position of the head can be locked for transportation and
service with the tilt lock. To lock or unlock the head, pull the lock
out and turn it one-quarter turn in either direction.

Disassembly
