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
cleaning parameters in the table
(see Table 15: Turbine wet cleaning, recommended oper-
).
If an optional flowmeter (04) is present, set the water volume flow V
W
on the basis of
the
cleaning parameters in the table
(see Table 16: Wet cleaning of turbine, parameters
.
u
Close the stop valve (02) after 10 minutes.
u
Wait for 10 minutes; do not change the load during this stabilisation phase.
