3.3 Mounting the UV protective shield
A UV protective shield (6.2745.100) pre-installed on a metal ring is inclu-
ded in the scope of delivery for the 909 UV Digester.
Proceed as follows:
1 Using the hex key (6.2621.100), unscrew the stop's hex socket head
screw (2-6) on the back of the housing and remove the stop.
Keep the stop with the hex socket head screw in reach. It will have
to be screwed back in place on the housing afterwards.

2 Place the UV protective shield over the wet end's opening so that the
metal ring rests on the two front stops (2-3).
