The suction lines are equipped with foot valve and filter nut.
The reed contacts are integrated in the suction line body.
The floats with magnet core are located axially on the valve body and are
sliding.
The foot valve should be dismounted and cleaned occasionally, at the latest
when the suction performance drops.
The function symbol (NO contact) must be present on the top surface of the two
floats.
If this is not the case, disconnect the float and reverse the polarity.

Prior to any maintenance work on the reactor, purge
the system with water until no more chemicals are
present.
Check the valves on the reactor for leaks each time
maintenance work is carried out on the chlorine dioxide
system. Replace valves if necessary.
The reactor valves are not identical to the valves of the
dosing pumps!
Do not interchange the valves!
