With regular maintenance you can ensure that the PAL performs at its optimum without interruptions. Dirty lenses and filters
reduce the brightness and diffuse the projected image. Cooling fans covered by dust may cause overheating, thus causing the
thermostat to cut out the lamp intermittently. This section not only takes you through the general maintenance procedures, but
also describes some basic service operations which you can carry out yourself.
Read the following descriptions carefully before attempting to make any adjustments
whatsoever. If you do not feel completely competent to make the corrections you should

The PAL has been designed with ease of servicing and maintenance in mind and is constructed in a totally modular fashion. If
there is a problem in any particular section, or you want to put in your own custom gobos or color filters, or you need to clean
parts of the fixture, it is a simple operation to remove and replace any module.
Ensure that the fixture is disconnected from mains power before proceeding.

1. The bottom cover is secured by means of four 1/4-turn fasteners. Release the cover by turning the fasteners
counter clockwise, and then remove the cover downwards, thus revealing the inside of the fixture (see diagram on
next page). As you remove the cover you will notice that a safety wire secures it to the chassis. You may leave the
cover hanging on the safety wire while servicing the fixture.

2. Locate the module that you wish to remove from the fixture. You will see that there are some PCB connec-
tors connecting the module to a wiring loom. Remove these connectors taking care to note the location and
direction of each one.
3. On each side of every module there is a thumbscrew. Unscrew these and carefully pull the module straight
out of the fixture.
