Operation

  Filtration process

1.Open the inlet to fill the filter housing with the fluid gradually.

Make sure that the shell gasket and nut gasket are properly fitted.

2. Purge the air in the filter housing from the vent.

3. When the fluid comes out from the vent, close the inlet and tighten the vent plug.

4. Then open the inlet to pressurize the filter housing up to the working pressure.  

Make sure that the shell gasket and nut gasket do not have leakage.

5. If you find any leakage of the fluid, close the inlet and loosen the vent plug to depressurize the filter housing.

6. Tighten the cap nut.

7. Open the inlet again to pressurize the filter housing and check if the fluid is leaking.

8. When you find no leakage, open fully the inlet and the outlet for filtration.

If you pressurize the filter housing up to the working pressure all at once, the fluid may blow out form the point 

where the fluid is leaking.

Loosen the vent plug slowly not to let the fluid blow out. 

   How to remove a cartridge

1. Close the inlet and the outlet to stop running of the fluid in the filter housing. 

2. Loosen the vent plug to depressurize the filter housing gradually. 

3. Loosen the drain plug to let out the fluid in the filter housing. 

4. Loosen the cap nut and remove it 

5. Remove the cover from the shell.

6. Pull out the used cartridge from the center rod.

When you loosen the cap nut, you can remove the components from the head. So, hold the cover firmly not to let 

the components drop. 

Deal with the shell most carefully no to let its end have scratches.

Clean up the components.  Use a cleaning fluid compatible to the fluid for filtration.
