1. When installing the plug-in filter element, immerse the O-ring into clean parallel filtrate to reduce friction during insertion. Require to insert it all the way through, with both O-rings providing a sealing effect.
2. When installing the snap on filter element, it is necessary to rotate clockwise for positioning.
3. If the filter has a pressure plate, press the pressure plate onto the warped part and gently press the spring on the pressure plate. If the spring is too tight, there will be no room for the filter element to extend, which will cause distortion and affect the filtration accuracy.
4. When filtering liquids, first turn on the exhaust switch on the casing to empty the gas inside the filter cartridge and fill it with liquid, otherwise it will affect circulation.
5. Fluid filters will experience pressure drop due to resistance. To overcome resistance, it must have sufficient working pressure. To avoid the impact of high flow on the filter element, the valve should be slowly opened.
