Fulfil prerequisites.
u
Ensure that the water supply (01) is guaranteed.
u
Open the stop valve (02) and set the required water pressure at the manometer (3) (see
u
cleaning parameters in the table
ating state →70)).
If an optional flowmeter (04) is present, set the water volume flow V
cleaning parameters in the table
→71).
Close the stop valve (02) after 10 minutes.
u
Wait for 10 minutes; do not change the load during this stabilisation phase.
u
If the cleaning result is unsatisfactory or there is water leakage, contact a Turbo Systems
