Evaporative Emission System Tester Self Test

  1. Verify gas cylinder valve is closed and control valve (located on tester) is in TEST position. All tester displays should be off at this time.
  2. Connect long hose (part of SST ) to tester.
  3. Connect manifold assembly (part of SST ) to long hose as shown.
  4. Open gas cylinder valve and verify gas cylinder regulator left gauge reads 10 to 12 psi (preset at factory). If not, see tester operators manual to contact tester manufacturer.
  5. Press ON/OFF switch to turn on SST and make sure left display reads 0.0. Turn control valve on tester to FILL position.
  6. Verify left display reading is within 13.9 to 14.0 inches of water. If not, adjust pressure using regulator knob located on right side of tester.
  7. Turn control valve to TEST position and press START switch.
  8. After 2-minute countdown (left display) is completed, right display shows total pressure loss for that period. A 0.5 inch of water loss is acceptable on self-test. If loss is more than 0.5 inch of water, perform one or more self-test. If failed test repeats, check for leak using the ultrasonic leak detector (part of SST ).
