NOTE:
If the tester does not work correctly during self‐test, refer to the tester operators manual for more detailed procedures.
a. Verify the gas cylinder valve is closed and the control valve located on the tester is in the TEST position. All tester display should be off at this time.
b. Connect the long hose (part of SST) to the tester.
c. Connect the manifold assembly (part of SST) to the long hose as shown.
d. Open the gas cylinder valve and verify the gas cylinder regulator left gauge reads 10 to 12 psi (preset at factory).
If not, refer to the tester operators manual to contact tester manufacturer.
e. Press the ON/OFF switch to turn on the SST and make sure the left display reads 0.0.
f. Turn the control valve on the tester to the FILL position.
g. Verify the left display reading is within 13.9 to 14.0 in of water.
If not, adjust the pressure using the regulator knob located on the right side of the tester.
h. Turn the control valve to TEST position and press the START switch.
i. After the 2-min countdown (left display) is completed, the right display shows the total pressure loss for that period. A 0.5 in of water loss is acceptable on the self‐test.
If the loss is more than 0.5 in of water, do one or more self‐test. If the failed test repeats, check for leak using the ultrasonic leak detector (part of SST).
