5. Start-up
If the pump is not operating satisfactorily, see section 9. Fault finding chart.
6. Calibration
It is important that the pump is calibrated after instal-
lation to ensure that the correct value (ml/h or l/h)
appears in the display.
The calibration can be carried out in three different
ways:
• Direct calibration (recommended).
The dosed quantity of 100 strokes is measured
directly. See section 6.1.
• Indirect calibration.
A calibration factor selected from a table is used
for the specific installation. This method can be
used if it is not possible to carry out a direct cali-
bration. Indirect calibration will never be as accu-
rate as direct calibration. See section 6.2.
• Check calibration. See section 6.3.
Step Action
1
Connect the hoses/pipes:
• Connect the suction and dosing hoses/pipes to the pump.
• Connect a hose to the vent valve, if required, and lead the hose to the
tank.
2
Switch on the electricity supply:
• The display is on.
• The green indicator light is flashing (the pump has stopped).
• Select language, if required, see section 4.9.
3
Start the pump:
• Start the pump by pressing the on/off button.
• The green indicator light is permanently on.
4
Priming/venting:
• Press the button on the pump control panel and let the pump run
without a counter pressure. Loosen the vent valve by giving it a 1/8 to
1/4 turn, if required.
When the buttons and are pressed simultaneously during prim-
ing, the pump can be set to run for a specific number of seconds at
maximum capacity.
5
Calibration:
• When the pump has been primed and is running at the right counter
pressure, calibrate the pump, see section 6.
