Product description - Function
When dosing chemicals from two containers, the “switch-over automatic” automatically switches the suction
to the full container as soon as one container has been emptied. The empty container can then be exchanged
for a full one at any time. This
ensures a continuous supply
of chemicals to the swimming pool circuit, and
there will be no interruption in dosing due to an empty container. In addition, the time window for changing
the empty container increases considerably.
