Commissioning Glanded pumps

For perfect functioning of the pump(s) / system(s), it is recommended to have the commissioning carried out by the works' own WILO SE Customer Service Department. Optimum setting and efficient operation of the system are ensured as a result. Commissioning is comprised of the following points:

  • Commissioning of system(s) according to checklist
  • Parameterisation and setting of switchgear
  • Testing and adaptation of initial compressing of pressure tanks (filling up to 80 litres incl.)
  • Functional check of fitted system(s)
  • Practice-oriented operation instruction
  • Wilo commissioning protocol

The price for commissioning only applies to system(s) which have been installed in accordance with the installation and operating instructions and state-of-the-art technology. No costs for any materials which may be required are included.
