Access and Maintenance
Displayer has a very unusual system for access to the inside of the projector. Although being left han-
ging in the position it’s installed in, the projector can be opened in half length-wise, thus enabling
extremely easy access to the components inside to carry out any necessary work (cleaning, relamping
or maintenance work on any mechanical or electronic parts, etc.).
To open the projector, unscrew the 2 knobs on the front (see illustration), making certain that the lower
part doesn’t drop downwards when the unscrewing is finished.
The opening is automatically locked in the fully open position.
Attention: before opening the fixture after it has been used for a while, wait for at
least 10 minute (the ideal time is 30 minutes), as the lamp and reflector reach
temperatures able to cause serious burns if touched.

After carrying out the necessary work, before pushing the lower part upwards (fig. 2) to close the
projector, release the locking lever by raising it (fig. 3). Tighten the 2 knobs one after another, making
absolutely certain that they are correctly hooked on to the lower part, to avoid it unexpectedly dropping
down again.
Relamping
Before replacing the lamp:
- make certain that replacement is actually necessary;
- disconnect the fixture from the mains supply;
- if the fixture was on, wait for the lamp and the internal mechanical parts to cool down
before opening (about 30 minutes are necessary).
Remove the burnt-out lamp. Make absolutely certain not to touch the lenses, reflector or the lamp itself
with your bare hands, as residue burns at this high temperature, blackening the parts and definitively
damaging the lamp. Fit the new lamp, mounting it carefully in its holder.
To ensure correct protection, it’s important that the lamp is perfectly fitted into the holder.
Every time the lamp is replaced, it’s advisable to always carry out a complete cleaning cycle.
