Switch-off 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-off procedure has to be integrated and the following instructions have to
be observed when switching off.
WARNING
Risk from sudden, unforeseeable or unauthorized reactivation 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.
Before performing any disassembly, maintenance, repair or cleaning work on the device,
it is imperative to carry out the following working steps in the specified order:
Switch-off procedure
1.
Stop the supply of cleaning agent (e.g. slowly close the shut-off valve or ball cock).
2.
Check that the supply of cleaning agent is stopped and there is no media pressure on
the device.
3.
Safeguard the supply of cleaning agent to protect it from sudden, unforeseeable or
unauthorized reactivation (e.g. lockable
switches
/
shut-off elements).
4.
Make sure that the cleaning device and supply line for cleaning agent have been
completely drained (e.g. by waiting before opening the container).
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, 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).
