4. Maintenance and stocking

4.1 CLEANING THE TURBINE

The meter has 2 magnets fitted into the turbine.
This magnets could attract metallic powders (if
present) that could block the turbine into the meter
body. For that reason, it could be necessary to
periodically verify and eventually clean the mag-
nets. To do this, unscrew the internal shaft and its
bolt. Take care to reassemble the turbine in the
correct mode as illustrated hereafter.

4.2 STOCKING

If the meter has to be positioned in stock for a
while, clean it carefully. This will help to prevent
eventual damages.
