After the detection operation, open the change over valve switch, discharge the filtering separator water catch bowl, retrieve the measuring glass 31 of taking the scale, discharged aviation oil together, it is lighter than water to retrieve oil in the sump oil bucket 41, prevents polluted environment and produces other unexpected incidents.

The volume controlled water is slowly pumped into the filter separator sump and if the emergency stop system is working properly, the fuel system will automatically stop when the water level in the sump touches the sensor, and this test is performed while the fuel system is running.

After the test is completed, when there is still pressure in the fuel system, the operator opens a drain valve to direct liquid from the filter separator oil sump to the model graduated water measuring cup 31, any fuel that is drained will float on the water surface, and the operator can then confirm that all the water that is injected into the sump has been removed.

The testing steps are as follows: firstly, putting clear water with a measured volume into a barrel or a graduated container, and marking a water level on the container;

secondly, connecting the rotary connector to a water outlet of the filtering separator;

then, starting the fuel refueling system, the tank refueling truck can be recycled, and the pipeline refueling truck must be matched with the oil tank for use;

then, when the normal flow and pressure are reached, opening a drain valve, and pumping water into a filter separator water collecting tank; in this process, the amount of water required to activate the float or sensor in the filtering separator depends on the design of the sump, the volume must be determined by testing each piece of equipment, and the operator must not inject more than this amount of water in order to prevent contamination of the fuel system;

subsequently, if the emergency shutdown system is operating properly, the fuel system will automatically stop. If it does not prevent fuel flow, the system must be repaired before the aircraft can be refueled.

Then, in order to clear the water in the sump after the test, a small switching valve is opened with a return hose in the tank to let some fuel flow into the container to ensure that all the injected water has returned, the switching valve is closed and when the water settles to the bottom of the container, the water level should be at the original mark created in the first step;

and finally, closing the drain valve, dismounting the rotary joint and finally completing the test work of the tester.
