
The pump, of which you want to determine the fault, may be hot or under
pressure. Take the appropriate precautions first and protect yourself with
the proper safety devices (safety goggles, gloves, protective clothing)!
To determine the source of the malfunctioning of the pump, proceed as follows:
1 Switch off the power supply to the pump unit. Lock the working switch with a padlock
or remove the fuse. In case of a combustion engine: switch off the engine and close
the fuel supply to the engine.
2 Close the stop valves.
3 Determine the nature of the fault.
4 Try to determine the cause of the fault with chapter 6 "Problem solving" and take the
appropriate measures or contact your installer.
