Fans and air passages
The fans and air passages must be cleaned approximately every 6 weeks; the
period for this periodic cleaning will depend, of course, upon the conditions
in which the projector is operating. Suitable instruments for performing this
type of maintenance are a brush and a common vacuum cleaner or an air
compressor.
Filters and air intakes
Air filters and intakes should be cleaned every month to maintain optimum
operation of the cooling system. The period for this periodic cleaning will
depend, of course, upon the conditions in which the projector is operating.
Remove the four screws which hold the filters in place on the rear of the pro-
jector body. Clean using an air compressor and, if necessary, a liquid deter-
gent solution.
Mechanicals
Periodically check all mechanical devices for wear and tear; gears, guides,
belts, etc., replacing them if necessary. Periodically check the lubrication of
all components, particularly the parts subject to high temperatures. If neces-
sary, lubricate with suitable lubricant, available from your coemar distributor.
Check that the bolts which affix the barndoors are firmly fastened.
Electrical components
Check all electrical components for correct earthing and proper attachment of all connectors, refastening if necessary.
11.3. Fuse replacement
Locate the fuse, which protects the lamp and electronics, in the base of the unit, as described in section
5.2 Altering the operating
voltage and frequency
. The fuse panel is shown in the picture which follows.
Using a multimeter, test the condition of the fuse, replacing it with one of equivalent type if necessary.
