Service; Lamp Replacement - Martin MAC 250 Wash User Manual

Service

The MAC 250 Wash requires regular maintenance to maintain peak performance. Refer any service that is
not described here to a professional technician.
Cleaning is vital. Excessive dust, grease, and smoke fluid buildup will degrade performance and cause
overheating and damage that is not covered by the warranty. Cleaning schedules for lighting fixtures vary
greatly depending on the operating environment. Cooling fans suck in airborne dust and smoke particles,
and in extreme cases fixtures may require cleaning in less than 50 hours of operation. Environmental
factors that may result in a need for frequent cleaning include:
• Use of smoke or fog machines.
• High airflow rates (near air conditioning vents, for example).
• Presence of cigarette smoke.
• Airborne dust (from stage effects, building structures and fittings or the natural environment, for example).
If one or more of these factors is present, inspect fixtures within their first 25 hours of operation to see
whether cleaning is necessary. Check again at frequent intervals. This procedure will allow you to assess
cleaning requirements in your particular situation. If in doubt, consult your Martin dealer about a suitable
maintenance schedule.
Danger! Intense heat. Avoid contact by persons and materials. The exterior of the fixture can get
very hot – up to 160° C (320° 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 that will almost certainly damage the fixture,
replace the lamp when it reaches the limit of its 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 dousing it.
Replace the lamp when:
• it strikes with difficulty or not at all, is visibly deformed or is in any other way defective
• hours of use reach the manufacturer's "replace before" limit. See Table 3.
