7.6 Removing the Clogging Indicator
Before any work is commenced, correct authorisation must be obtained from the appropriate responsible person.
Switch off the hydraulic system and release the pressure in the filter or system using the relevant bleed point.
(Collect any accumulated fluid in a suitable container and clean or dispose of the fluid in accordance with any local environmental
regulations).
Unscrew the clogging indicator using a 25mm spanner across the flats provided for fitting. Ensure the work area is as clean as
possible.
The hydraulic system must only be switched back on once the clogging indicator port has been fitted with either a pressure
resistant blanking plug or a suitable clogging indicator.
7.7 Installing the Clogging Indicator
• Lubricate the seal rings and thread on the indicator body, and the port in the filter head, with clean operating fluid.
• Apply thread sealant to the top two threads of the fluid connection. Avoid applying glue to the seals.
• Screw in the indicator using a spanner and tighten to the correct torque
• Switch on the hydraulic system and power supply to the clogging indicator.
• Check the clogging indicator for leakage.
• Vent the filter at an appropriate point.
• The clogging indicator only responds when fluid is flowing through the filter being monitored.
• The clogging indicator may respond during a cold start of the hydraulic system.
• If the clogging indicator responds during a cold start only, it is possible that the element does not
need to be changed yet.
Once the indicator is fitted, please refer to the appropriate operators guide/manual for the MP Filtri Stainless Steel Filter.
