Make sure the edge of the filter is cleared. Check the arcs and edges of the tennis basket. The upper edge of the net must be flat on the surface of the filter. If there are no nets or nets, there will be a filter failure. To install a new filter bag, the filter bag must be inserted into the net, and the bag sealing ring must be placed in the seal slot correctly.
In the new filter bag, the unused filter bags must be reloaded into plastic bags to prevent dust contamination. Turn off the power supply to stop the pump and close the inlet and outlet valve (for the user who now USES the filter bag). Release the pressure, be safe, and make sure that the nozzle is heading for safety. Opening the exhaust valve slowly lowers the filter pressure (for those who now use the filter bag). Open the lid to ensure the filter pressure drops to zero and open the lid. Take out the used filter bags. (for the user who now USES a filter bag)
Check the gasket and select the compatible gasket. Close the lid, especially when closing the lid of the filter, make sure the washer is not twisted or removed, and tighten the ring nut with clockwise. Close the exhaust valve and turn on the pump. Open the inlet valve and slowly open the valve to see if it is leaking. When a leak occurs, close the inlet valve immediately and open the exit valve from the restart.
