When installed, always replace the film disc cut-out each time a lamp has to be
replaced.

To replace a lamp, proceed as follows (for the tools to use, refer to page 43
“Screws Overview”):

Disconnect the fast-on connectors of the lamp from the terminal block (E1).

Remove the lamp (C ) from the lampholder (D3), holding the reflector.

If a cut-out is used, remove it by loosening the screw which secures the cut-out clip to the
terminal block (E1) and rotate cut-out clip free.

If a cut-out is used, position a new disc (small button side up) in the terminal block. Rotate
the cut-out clip on top of the cut-out and hold while tightening the screw. Make sure that the
pressure applied by the clip on the film disc is sufficient to assure good contact. If
loosened, remove the clip and bend it slightly to increase its pressure.

Install a new lamp.

To optimise photometric output, make sure that the lamp is correctly positioned with the
"arrow" pointing upside (up).

 Never touch the quartz bulb of the lamp with your bare fingers. It will reduce the

lifetime of the lamp considerably. Should it happen, clean the bulb with isopropyl alcohol.

Reassemble in reverse order.

Make sure there is good contact between fast-on connectors and terminals.

The illustration below clarifies the procedure:
