Stop the filtration pump
•
Close the isolation valves, if fitted
•
Remove the probe from the probe holder
•
Put the shutter washer (fig. 12) in to close off the hole in the
probe holder
•
Open the isolation valves, if fitted
•
Turn on the filtration pump and check that the ON/OFF switch
(I/O) of the pump is switched to “I”
•
Carry out the calibration of the probe and repeat the previous

or as required.
•
The procedure is renewed in case of abnormal consumption of
chemicals.
1. Remove the protective cap of the probe and keep it for
