7.4 Cleaning the device
You should check the function of the fans in
the head and foot at regular intervals. Above all,
make sure that the air intakes and the interior
of the P18 are free of fluff and dust.
To do this, open the head cover (4x camlocks (4)
with half a turn) and the base plate on the foot.
You can clean the P18 with a brush and a
vacuum cleaner. In addition, you can remove the
gobo insert (1) and the shutter slide insert (2) by
loosening the knurled screws (3) and sliding the
focus carriage towards the lens. Then you can
clean the colour filters, glass gobos and CMY
panes with a soft cloth and a little window cleaner.
To clean the frost flaps, prisms and zoom/focus
unit, remove the three Phillips screws (Fig. 4) and
then the cover (see Fig. 5). Ensure that you do not
bend or damage any parts during cleaning. When
cleaning is complete, reconnect the flap, replace
the Phillips screws (4) and return the inserts to the
unit.
