The way of exchanging the filter bag


1, turn off the system: turn off the power to stop the pump, close the inlet and outlet valves.


2. Release pressure: To be safe, make sure the nozzle is rushed to a safe place. Open the exhaust valve and slowly lower the filter pressure.


3. Open the lid: make sure the pressure drop of the filter cartridge is zero and then open the lid.


4. Discard used filter bags


5, check the basket: check the arc and edge of the basket. The surface of the upper edge of the basket in contact with the filter cartridge must be flat. Warning: If there is no basket or the basket is installed incorrectly, the filter will fail


6. Install the new filter bag: the filter bag must be inserted into the net basket. The seal ring must be seated correctly in the seal groove.


7, test gasket: choose a fluid compatible gasket, use the Chinese filter environmental gasket to replace the worn gasket
