    Important notes on operation Qualification of personnel The Condair ME Control must be commissioned and op erated only by personnel familiar with the sys- tem and adequately qualified for the respective tasks. It is the owner’s responsibility to verify proper qualification of the operating personnel.
  • Page 23: Initial Commissioning

    Initial commissioning The initial commissioning of the Condair ME Control may only be carried out by Condair authorized and appropriately trained technical personnel. Inspections Prior to initial commissioning the complete system must be inspected for correct execution of the instal- lations.
  • Page 24 If you are unsure of the quality of your water please consult your Condair distributor for advice.
  • Page 25 • After the disinfection process has completed, neutralise disinfectant, if required. 18. Power cycle the Condair ME Control to remove the forced disinfection demand (allowing normal control to be resumed) and check correct control operations (signals, fault outputs, Modbus/BACnet). 19. If commissioning has not been completed by an approved Condair representative, it is recommended that records are kept of commissioning date and software settings.

    After the demand has dropped to zero, the system drains a small amount of water to give space to the water running out of the matrix. Drain Check The Condair ME is draining the tank and uses the first section of the drain procedure to check whether the drain valve is working properly. Bleeding During operation the stage pumps are stopped periodically to bleed any air out of the pumps by the water flowing back from the distribution pipes.
