IMPORTANT INFORMATION

  • Filter housings must be earthed.
  • When using electrical clogging indicators, the electrical power supply to the system must be switched off before removing the clogging indicator connector.
  • If an extension tube is to be fitted to the two-piece filter housing, the tube must be made of synthetic material or thin-wall aluminium.
  • Extensions must be protected by fitting a bulkhead plate or other means of protection so that no forces can be transmitted to the filter housing or the extension.
  • The filter can normally only be used for tank-mounting
  • The filter must be fitted absolutely vertically, or after consultation with the manufacturer, only within the tolerances specified
  • The filter must not be used as a suction filter
  • Components (e.g. coolers) must not be installed after the filter
