Service; Lamp Replacement - Martin MAC 250 Krypton User Manual

S
ERVICE
The MAC 250 Krypton/Entour requires regular maintenance to keep performing at their peak. Excessive
dust, grease, and smoke fluid buildup degrades performance and causes 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 the it to
cool for at least 45 minutes before handling.
Do not removing 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 is an average figure that is based on the manufacturer's test cycle. For
maximum lamp life, avoid excessive strikes and always allow the lamp to burn for at least 5 minutes before
turning it off.
To reduce the risk of lamp explosion, which may damage the fixture, never exceed the lamp's rated life
(2000 hours) by more than 25 percent.
Replace the lamp when:
• it strikes with difficulty or not at all, or is in any other way defective
• usage exceeds the manufacturer's "replace before" hours. See Table 5.
