Jet Cleaner TANKO-JM
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. 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).
NOTE
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.
