6.3 Switch-on Procedure
In accordance with the type of device activation and how it is integrated (e.g. manual or automatic) on
the cleaning plant, the switch-on procedure has to be integrated and the following instructions have to
be observed when switching on.
WARNING
Risk from sudden, unforeseeable or unauthorized activation of the device (e.g. triggering
of a start command as a result of incorrect operation of a start-up control device)!
There is a risk of death or severe physical injuries.
When commissioning the device, it is imperative to perform the following working steps in
the specified order.
Switch-on procedure
1. Close all of the openings on the container (e.g. inspection openings).
2. Switch on the supply of cleaning agent (e.g. slowly open the shut-off valve or ball
cock).
3. Check that the supply of cleaning agent is NOT interrupted and the media pressure on
the device is established.
4. Take suitable measures to secure the supply of cleaning agent to prevent it from
switching off suddenly, unexpectedly or without authorization.
NOTE
Risk of breakage due to material overload!
Pressure surges when switching the cleaning agent on or off, in particular pressure
surges which exceed the operating pressure, and gas components in the cleaning agent
may cause 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
agent, e.g. caused by:
– installing a water hammer arrester or pressure relief valve in the supply line,
– starting up/stopping the pump slowly 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 provoked by quick changes in the flow speed (pressure
increase or pressure drop) or by sudden changes in direction of the flow of fluids. This effect is
particularly common in pump systems with long pipelines when starting up, stopping or changing the
speed of pumps.
