marl on the pump housing is reached.

CAUTION!
Danger of injury from hot water
In extended use against the closed pres-
sure side (>10 min.), the water in the
pump can be severely heated up and can
be emitted in an uncontrolled manner!
Isolate the unit from the mains and allow
the pump and water to cool down. Start
the unit again only after all the faults have
been rectified!
The risk of injury from hot water can arise if:
the installation is not correct
the pressure side is closed off
there is a lack of water in the suction line, or if
the pressure switch is defective.
Procedure
1. Isolate the unit from the mains and allow the
pump and water to cool down.
2. Check the unit, the installation and water le-
vel.
3. Start the unit again only after all the faults
have been rectified!
