Service and maintenance
Warning! Read “Safety Information” on page 4 before servicing the MAC Encore Performance.
Warning! Disconnect the fixture from AC mains power and allow to cool for at least 30 minutes
before handling. Do not stare into the light output. Be prepared for the fixture to light and move
suddenly when connected to power.
Warning! The MAC Encore Performance™ contains components that are accessible and live at high
voltage while the fixture is connected to power and that remain under tension for 30 minutes after
power is disconnected. Only technicians who are authorized by Martin and who have the Martin
service documentation for the MAC Encore Performance are permitted to open the fixture. Users
may carry out external cleaning as described in this section, following the warnings and
instructions provided, but any service operation not described in this manual or in the fixture’s User
Guide must be referred 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.
The user must clean the MAC Encore Performance periodically to maintain optimum performance and
cooling. The user may also upload firmware (fixture software) to the fixture via the DMX data input port or
USB port using firmware and instructions from Martin. All other service operations on the MAC Encore
Performance must be carried out by Martin, its approved service agents or trained and qualified personnel
using the official Martin service documentation for the MAC Encore Performance.
Installation, on-site service and maintenance can be provided worldwide by the Martin Professional Global
Service organization and its approved agents, giving owners access to Martin’s expertise and product
knowledge in a partnership that will ensure the highest level of performance throughout the product’s
lifetime. Please contact your Martin supplier for details.
It is Martin policy to apply the strictest possible calibration procedures and use the best quality materials
available to ensure optimum performance and the longest possible component lifetimes. However, optical
components are subject to wear and tear over the life of the product, resulting in gradual changes in color
over many thousands of hours of use. The extent of wear and tear depends heavily on operating conditions
and environment, so it is impossible to specify precisely whether and to what extent performance will be
affected. However, you may 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.
Tilt lock
The tilt position of the head can be locked for service. See Figure 1 on page 7. Push the lock in towards the
yoke in one direction to lock the head and back in from the other side to unlock the head.
Important! Release the tilt lock before applying power to the fixture and before packing the fixture in its
flightcase.
Access to the head
Warning! Disconnect from power and allow to cool for 30 minutes before opening the head.
To open the head:
1. Disconnect the fixture from power, allow components to cool for 30 minutes and apply the tilt lock.
2. See Figure 9. Remove the top head cover by loosening its two Torx 25 captive retaining screws A until
the screws turn freely. Lift the front of the cover slightly away from the head, then slide the cover towards
the front of the head to release the rear of the cover.
