Cleaning or replacing the
optional strainer
The optional strainer must be cleaned or
replaced regularly to avoid contamination or
blockages. The frequency of cleaning or repla-
cement depends on the degree of contamina-
tion caused by the sample water.
1 Close the shut-off ball valve on the sample
water inlet in front of the strainer.
2 Unscrew the strainer and rinse it with
water. Catch escaping water in a contai-
ner.
3 Remove the strainer screen and rinse it
under running water or replace it.
4 Fit the strainer screen again and reinstall
the strainer.
5 Open the shut-off ball valve on the sam-
ple water inlet and outlet again.

Cleaning

rit, scouring agents)! We recommend that you
use a moist cloth with a neutral household
cleaning agent.
