Service

Warning! Read “Safety information” on page 5 before servicing the MAC 250 Wash. Disconnect the

fixture from power and allow to cool for 45 minutes before handling or removing any cover.

Refer any service operation not described here to a qualified service technician.

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.

The MAC 250 Wash requires regular maintenance to maintain peak performance.

It is Martin policy to use the best-quality materials and coatings available to ensure optimum performance

and the longest possible component lifetimes. However, optical components in all lighting fixtures are

subject to wear and tear over the life of the fixture, resulting in gradual changes in color rendition of dichroic

filters or the specular properties of reflectors, for example.

The extent of wear and tear depends heavily on operating conditions, maintenance and environment, so it is

impossible to specify precise lifetimes for optical components. However, you will 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.

As with electronic components in general, the MAC 250 Wash’s PCBs are sensitive to ESD (electrostatic

discharge). Take precautions to avoid ESD damage before opening the fixture. Service electronic

components at a static-safe workstation only.

Cleaning guidelines

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. To maximize the life of the MAC 250

Wash and protect the investment it represents, clean the fixture regularly – especially the

cooling systems – following the guidelines in this section.

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.
