NOTE
Risk of breakage due to material overload!
Pressure surges when switching the cleaning medium on or off, in particular pressure
surges that exceed the operating pressure, and gas components in the cleaning medium
may result in hammering in the cleaning device.
There is a risk of material damage or destruction of plant parts, (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. caused by:
–
Installing a water hammer arrester or pressure relief valve in the supply line,
–
Slowly starting/stopping the pump and
–
opening/closing the shut-off fitting slowly (e.g. valve or ball cock).
The term “water hammer” denotes a pressure surge in a fluid line which is generated by
opening/closing a shut-off fitting (e.g. valve or ball cock) quickly at the end of a pipeline.
Pressure hammers/pressure surges can also be caused by quick changes in the flow rate (pressure
increase or pressure drop), or by sudden changes in the direction of flow of fluids. This effect is
particularly common in pump systems with long pipelines when starting up, stopping or changing the
speed of pumps.

Operation
Once it has been started up and inspected, the device can be put into operation, observing the following
instructions.
WARNING
Danger of collisions with moving parts!
When the production process starts, there is a risk of collision if the spray head of the
retractor system is not completely retracted and if movable and movable components
in the container are in motion. This can lead to damage to the spray head and the
components.
There is a risk of death or severe physical injury.
The production process may only be started when the spray head is completely
retracted and locked.
