Operating Instructions
PREFILLING
1. Close the air shut-off valve. Adjust the air regulator to zero pressure by turning the valve handle on top of the regulator in a counterclockwise
direction until no turning resistance is felt.
2. Open the cabinet of the tester and place the hose assembly to be tested on the aluminum rack of the tester.
3. Connect the umbilical hose assembly to the hose assembly to be tested using the appropriate adapter combination. Umbilical hose has a -8
JIC swivel fitting on its terminal end.
4. Ensure that the high pressure dump valve is completely closed.
5. Open the water shut-off valve and fill the assembly a/lowing the tap water to force the air from the hose assembly through the non-capped
end.
6. When the sample is completely filled, shut off the water and cap or plug the open end of the hose assembly.
PRESSURIZING
1. Close the cabinet and latch both clasps securely. DO NOT ATTEMPT TO PRESSURE TEST THE HOSE ASSEMBLY WITH THE CABINET DOOR OPEN
OR WITH THE LATCHES NOT SECURE.
2. Reopen the water shut-off valve to supply ample water to the pumping unit during pressurization.
3. Open the air shut-off valve.
4. While monitoring the test pressure gauge, adjust the air regulator valve clockwise allowing the pumping action to begin. Steadily increase
air pressure until the test pressure is approaching, then back off the air pressure until the pumping slows greatly. When the test pressure is
reached, back off the air pressure just enough to stop the pumping action.
5. The test assembly should remain pressurized at the proof test pressure for one minute. During this time the assembly should be observed
through the transparent Lexan lid. Pinhole leaks or seeping fittings may not be immediately apparent, so careful observation is important.
6. Once the test pressure has been obtained, tighten the locknut on the regulator. Subsequent assemblies can be pressurized to the test pres-
sure by merely opening the air shut-off valve on the pump. The air regulator will only require readjusting when a new test pressure is required.
TEST PRESSURE RELEASE
1. Close the air shut-off valve on the water pump.
2. Close the water shut-off valve located on the water pump.
3. Open the high pressure dump valve to release the water pressure in the test sample.
REMOVING THE ASSEMBLY
1. WAIT UNTIL ALL PRESSURE IS REMOVED FROM THE SAMPLE! This will be indicated by zero pressure indicated on the pressure gauge and no
water draining from the pressure discharge port in the tester.
2. Open the cabinet and remove the umbilical hose and test tooling from the tested assembly.
3. Drain the remaining water from the tested assembly. It is recommended that all hose assemblies be blown dry with compressed air.
