Y-Strainer Maintenance
To check and clean the suction screen in the Y Strainer, first shut down the ThermoJet and turn
OFF the nitrogen supply. See the section titled
Shut Down Procedures
on how to turn the
ThermoJet Oil Purifier OFF.
Close the nearest oil block valve to the ThermoJet oil inlet connection.
To drain the collected contents that have been collected in the Y-strainer basket, you only need to
remove the small plug from the bottom of the strainer. Collect and properly dispose of all
collected contents.
To remove and clean the strainer screen, remove the large plug. The suction screen along with
the dirty oil and particulate can be removed from the bottom of the strainer. Collect and properly
dispose of all collected contents. Clean the suction screen by washing and flushing. The use of a
brush may be necessary to remove small particulate for the screen mesh. Check the plug seal
and replace if necessary.
Once cleaning is completed, install the suction screen into the bottom of the Y-strainer body,
using the plug to hold in place. Ensure that the plug is tight to avoid leaks or pump cavitation
when restarting the machine.
