Test run

Do a test run before operating the lifting unit in automatic mode. A test run examines the correct functioning and impermeability of the unit. If necessary, adjust the pump’s follow-up time to make sure of the optimum operation of the unit

  1. Lifting unit is installed correctly.
  2. Connections are checked for correctness.
  1. Activate the lifting unit: Put the plug into the socket.
  2. Set automatic mode on the switchgear.
  3. Open the shut-off valve in the discharge pipe. NOTICE! Keep the shut-off valve in the inlet closed.
  4. Disassemble the ventilation pipe: Pull out the ventilation pipe from the HT double socket.
  5. Slowly fill the collection tank with water through the ventilation opening with a hose. NOTICE! Risk of malfunction! Do not hold water jet directly above the float switch.
  6. Switch on and off the lifting unit through level control device.
  7. Do no less than two full pumping operations of all pumps for a test run.
  8. To examine the duty point, fill the discharge pipe fully with water. Do more test runs until the discharge pipe is fully filled.
  9. Assemble the ventilation pipe: Put the venting pipe into the HT double socket. NOTICE! Tightly seal the ventilation connection.
  10. Examine all connections for impermeability.
  11. If all connections are leak-proof, the lifting unit can run in automatic mode.
  1. Test run is completed.
  2. Lifting unit is commissioned: Keep shut-off valve open in the discharge pipe.
  3. Lifting unit is in standby mode: Close the shut-off valve in the discharge pipe.
