10 Troubleshooting
WARNING
Disconnect and lock out the power supply to the pump drive before any
work is carried out. In case the motor is fitted with a frequency controller
and has a single-phase power supply, wait two minutes to make sure that
the capacitors have discharged.
If the hose pump does not function (correctly), consult the following check list to see if you can
remedy the error yourself. If you cannot, contact your Bredel representative for advice.
