Chapter 4---Maintenance (Removal/Replacement)

The power interlock switches for both covers are attached to each cover hinge.

5.When the Latch Levers are inserted into the holding slots, lift the cover off. Be careful not to brush against any of the internal components of the projector when removing the cover. If any undue resistance is felt, stop to locate the source before proceeding.

6.Replace the covers in reverse order from above. When replacing either cover, make sure the slot in the cover fits over the bottom of the projector case or the cover will not close correctly.

4.3Air Filters

Air filters should be cleaned whenever necessary. In extremely dusty or dirty conditions, the filters should be cleaned more frequently. Remove the filters and vacuum them or blow them clean with compressed air. They may also be washed with soap and water.

There are 4 polyurethane air filters in the Model 200 that require periodic cleaning. They are located as follows:

•1 metal-framed filter in the rear of the projector in the bottom cover-accessible when the rear cover is off (Figure 4-1).

•1 filter on the bottom of the projector-slides out from the middle-left side of the projector (grasp the hole in the filter frame). The filter can be peeled off the Velcro on the frame, if necessary (Figure 4-11).

•1 filter under the front cover, on top of the Arc Lamp and Optical Assemblies-accessible with the front cover off (Figure 4-1). This filter is also a peel-off type.

•1 metal-framed filter in the front-left-bottom cover accessible with the front cover off (Figure 4-11).

4.4Arc Lamp Assembly

The Arc Lamp Assembly consists of the Arc Lamp, the Ignitor, and the Laser Power Supply housed inside a Lamphouse Dock. An Arc Lamp can be removed and replaced separately from the entire assembly. The Ignitor and Laser Power Supply are sent back together as part of the Lamphouse Dock.
