8.8 Cleaning the system
Warning
Danger of electric shock!
Water or other liquids on electrical components can
lead to personal injury from electric shock. Damage
to the equipment can be caused by short circuits.
Keep all electrical components dry!
Never use water or any other liquid to clean electrical
components or electrical lines of the system!
If necessary, clean all system surfaces with a dry and clean cloth.
8.9 Checking the feed water supply
If the system is connected to an upstream break tank, check that:
•
the suction line is not leaking.
– If air is in the suction line, check that the non-return valve at
the outlet of the break tank is installed correctly and does
not leak.
•
there is sufficient water in the break tank.
•
the manual valve at the outlet of the break tank is open.
If the system is connected directly to the raw water source, check
that:
•
the coarse strainer upstream the foot valve at the suction point
is not blocked by dirt.
•
the suction line is not leaking.

This section refers to fig.: 6-9.
The strainer (11) is only present in systems without self-cleaning
prefilter module to ensure, that no particles larger than 300 µm
enter the UF membrane. It needs to be cleaned frequently,
depending on the feed water quality.
The strainer (27) is only present in systems with internal CIP
module. It ensures that no particles loosened during internal CIP
are flushed into the UF membrane.
Position of the component
