5 Start-up and operation
5.1 OPV adjustment
The OPV is fixed to the standard sieve with an overlying white plastic board
whereof 50% can be opened, so it is still possible to fill PAUL
®
manually with a
bucket via the sieve.
It is important that the arm with the float can move freely , as it has to float and
thus stop water flow when the water level rises. Please check this and eventu-
ally assure this by checking that the screw, see Figure 13, is not tightened too
hard.

®
If the screw is too tight, the arm with the float cannot move freely, which results
in that it might stay in the "open" position although water level is rising even
above the float, resulting in an unwanted overflow of
PAUL
®
.
In case you receive the OPV separately and have to exchange the sieve by the
OPV, please note the following: Due to transportation reasons, the arm with the
float might be in a position as can be seen from Figure 14. Before mounting the
OPV, please rotate the float arm so it is vertical below the sieve. To do so,
loosen the screw (red arrow in Figure 14). After adjusting, please
tighten again
this screw!
do NOT tighten this
screw too hard
