ERVICE
The MAC 250 Krypton 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 1.
Refer to "Lamp installation" on page 6 for the lamp replacement procedure.

Cleaning

O P T I C A L C O M P O N E N T S
Use care when cleaning optical components. The surface on dichroic filters is achieved by means of special
multi-layer coatings and even small scratches may be visible. Residues from cleaning fluids can bake onto
components and ruin them.
1 Allow the components to cool completely.
2 Wash dirty lenses and filters with isopropyl alcohol. A generous amount of regular glass cleaner may also
be used, but no residues may remain.
3 Rinse with distilled water. Mixing the water with a small amount of wetting agent such as Kodak Photoflo will
help prevent streaking and spotting.
4 Dry with a clean, soft and lint-free cloth or blow dry with compressed air.
F A N
To maintain adequate cooling it is important that the fan be cleaned regularly. It can be cleaned with a soft
brush, vacuum, or compressed air.
