NOTE
Risk of breakage due to material overload!
Pressure surges when switching the cleaning medium on or off, in particular pressure
surges which exceed the operating pressure, and gas components in the cleaning
medium can cause hammering in the cleaning device.
There is a risk of material damage, e.g. leakage in the pipe system or on connected
devices.
Prevent pressure surges (“water hammers”) and gas components in the cleaning
medium, e.g. by:
–
Installing a water hammer arrester or pressure relief valve in the supply line,
–
Slowly starting/stopping the pump and
–
Slowly opening/closing the shut-off fitting (e.g. valve or ball cock).
