3.2.3 Bleeding the Metering Pump
The metering pump must be bled when the pump
has drawn in air (e. g., because the metering con-
tainer is completely empty).
• The system stops; the “Motor/hard water“ mal-
function indication is shown in the display.
• Fill the empty metering container and mix the
chemicals according to Section 3.2.6.
• Unscrew the bleeding screw (34) by one turn.
• Press the MANUAL pushbutton (33) until the
medium flows without bubbles through the
bleeding line (35) back into the container.
• Screw in the bleeding screw again.
• On the control panel, acknowledge the mal-
function indication with the RETURN key but-
ton (36); the system starts.
3.2.4 Replacing the Fine Filter
Check the pressure difference at manometers (15)
and (16). Replace the filter insert when over 0.8 bar:
• Switch off the equipment at the main switch (20).
• Stop the untreated water supply.
• Place a bucket under the untreated water drain
cock (37) and open the cock.
• Wait until no more water emerges out of the
cock, then shut the cock again.
• Attach the filter wrench (41) to the filter bowl
(40) and screw off the filter bowl.
• Remove the filter insert (38) from the filter bowl
and replace with a new one.
