5.1 Cleaning
The separated sediment collected inside the
separator bowl must be removed manually. The
length of the cleaning interval depends on the
liquid flow rate and on the amount of solids.
During the initial period, open and inspect the
bowl once a day to determine the necessary
cleaning interval. The bowl must be cleaned
before the solids layer has become thicker than
10 mm. Otherwise there will be risk of that the
clean liquid outlet in the bowl will be covered by
solids.
‘‘5.4.2 Cleaning of bowl” on page 32 explains how
to proceed.
WARNING
Entrapment hazard
To avoid accidental start, switch off and lock
the power supply before starting
any
dismantling work. Make sure that rotating
parts have come to a
complete standstill
before starting any dismantling work.
NOTE
Never use cleaning agents with a pH below 6
or above 9 as they can damage the metal
surfaces.
