Float tank
The float tank (2) is integrated in the chassis. It
is located on the right-hand side, underneath the
scale inhibitor tank.
The float tank uniformly supplies the pump with
water. It also serves as a partition between the
water inlet (1) and pump and prevents cleaning
agent from getting into the water supply line in
the event of damage.
Float valve
Water flows through the open float valve (4) into
the float tank (2).
As the water level rises the float ball (3) lifts and
closes the float valve (4).
The float valve (4) is permanently set and must
not be adjusted.
