    Cleaning Warning! Pressure shock by evaporating liquid! ► Completely empty the system before steam sterilisation. Notice Disposal of cleaning agents ► Dispose of cleaning agents properly and in an environmentally friendly way. CIP stands for Cleaning in Place, the pump is completely rinsed with cleaning agents.

  • Page 37: Sip

    Cleaning SIP stands for sterilisation in place, in which the pump is sterilised with superheated steam. For steam sterilization or sanitization, minimum temperatures of 121 ° C (250 ° F) must be applied to all wetted surfaces. The maximum permissible temperatures can be obtained from the section technical data.
