Service; Lamp Replacement - Martin MAC 250 ENTOUR User Manual

ERVICE
The MAC 250 Krypton/Entour requires regular maintenance to maintain peak performance. Excessive dust,
grease, and smoke fluid buildup will degrade performance and cause overheating and damage that is not
covered by the warranty. The maintenance schedule will depend on the application and should be
discussed with your Martin distributor. Refer any service that is not described here to a professional
technician.
Danger! Intense heat. Avoid contact by persons and materials. The exterior of the fixture can get
very hot - up to 120° C (248° F). Disconnect the fixture from AC power and allow it to cool
for at least 45 minutes before handling.
Do not remove covers while the fixture is powered on, as this exposes dangerous live
electrical circuits, hot surfaces, and a lamp under high pressure.

Lamp replacement

Lamp life will vary. The rated life of a lamp is the average operating life before lamp failure in the
manufacturer's test cycle. To reduce the risk of lamp explosion, which may damage the fixture, we
recommend that lamps be changed when they reach the limit of their rated life. Never exceed a long-life
lamp's rated life (3000 hours for the Philips MSD 250/2) by more than 10 percent.
For maximum lamp life, avoid excessive strikes and always allow the lamp to burn for at least 5 minutes
before turning it off.
Replace the lamp when:
• it strikes with difficulty or not at all, or is in any other way defective
• hours of use exceed the manufacturer's "replace before" limit. See Table 6.
