Entrapment hazard
Switch off the power supply, remove the electric cables
from the sockets and 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

9.1
Cleaning
9.1.1
Strainer
The strainer has to be cleaned regularly. During the initial period, open and inspect once every
week to determine the necessary cleaning interval.
NOTE
When fitting the filter housing it must first be filled with liquid to prevent the pump operating in dry condition.
Otherwise the life of pump will be shortened.
9.1.2
Separator
The separated solids 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 that the
clean liquid outlet in the bowl will be covered
by solids.
