5.4 Connecting the Chemical Tank for Commissioning

Faults during the test run
Should you identify a fault during the test run, first
remedy this fault. Only approve the metering system
after a further test run with distilled water providing this
test run is fault-free.
Details on the set up of the individual components can
be found in the corresponding operating instructions for
the respective components.
Start-up the respective metering pump with a 100%
stroke. The stroke length settings are not pre-set.
1. Make sure that all fittings are in the operating position and the over‐
flow connector on the multifunctional valve/back pressure valve is
connected and the overflow connector is led back into a tank.
2. First, fill the two tanks provided on site with water for the test run.
3. Guide the suction lance correctly into the tank filled with water and
check the discharge side connector to the injection point.
4. Start the test run of the metering pump (left line) and check all fit‐
tings and connections have the correct operating setting.
5. Counting the pump strokes enables you to identify the quantity
removed.
6. Run the metering pump for a few minutes to allow all air bubbles to
escape from the metering system. Set the pump to the required
metering volume. You can adjust the pump output by changing the
stroke rate and stroke length.
ð If the discharge line is routed into a collecting tank, you can
measure the metered volume to determine a metering volume.
Switch off the metering pump again afterwards.
7. Drain the metering system and fully remove water and contaminants
from the metering system. The metering system can be drained by
blowing compressed air through the lines. Do not allow the air pres‐
sure to exceed the metering system's permissible operating pres‐
sure.
WARNING!

Check the safety data sheet regularly and replace, if
necessary, as the hazard potential of a substance can
be re-evaluated at any time based on new findings.
The system operator is responsible for ensuring that
these safety data sheets are available and that they are
