Connecting the Leak Checker

  1. Position the leak checker where it can be easily attached to the auxiliary valve of the pump cart. You will probably need to attach two vacuum hoses together to achieve this.
  2. While the leak checker is still capped at the inlet, turn it on. This will allow the leak checker to spin up its internal turbo.
  3. Note: If you wish to get a new calibration, leave the leakchecker running for about 20 minutes, before starting a calibration. You will probably not need to re-calibrate as the calibration will fix factors of 2 or 3, while we are interested in factors of 10-100.
  4. When the turbo has spun up, hold STOP for 3 seconds, to allow the leak checker to vent.
  5. Check to make sure that the auxiliary valve on the red pump cart is CLOSED! Failure to do this can ruin the pump cart.
  6. Attach the leak checker to the auxiliary valve on the pump cart. You may need two hoses.
  7. Press start on the leak checker. Wait until the pressure on the leak checker has bottomed out.
  8. On the pump cart, close the roughing valve.
  9. On the pump cart, open the auxiliary valve. enumerate
