Getting Started with the EVAPro After you remove your EVAPro from the box, check to make sure you have all accessories shown below. Click here for next screen

Connect nitrogen or shop air supply hose to the quick-connector shown below. The EVAPro comes with a built-in regulator that allows you to use nitrogen for all EVAP testing or shop air for all of your general purpose leak detection needs. Click here for next screen
Choose the proper EVAP port adaptor for the Vehicle from the accessory kit. The Schrader removal tool is used for taking the core out of the EVAP service port. Click here for next screen
Because of the volatile fumes that may be present in an evaporative emissions system, we recommend using an inert gas, such as nitrogen, for testing EVAP systems. Do not perform tests near a source of spark or ignition
TEST SAFELY Q: Why use Nitrogen to test EVAP system? A: SAE published Paper reports the hazards of using air instead of Nitrogen to test the EVAP system. Q: What is BAR requiring on the California BAR-Certified equipment? A: BAR says only Nitrogen can be used in BAR-Certified equipment, citing equipment requirements and safety concerns. Q: Why do some other smoke machine companies say you dont need to use Nitrogen with their machines? A: Most likely because their machines are not built with the licensed, patented technology to use nitrogen. Sounds like an attempt to put the best spin on a product that CANT use Nitrogen. Note: All current Vacutec smoke machines contain patented technology designed to be used with Nitrogen for safer EVAP testing.
1. Remove the OBD-II service port adaptor cap. 2. With the Schrader removal tool turn clockwise and remove the core from the service port *. You must remove the core before testing. [After testing,dont forget to reinstall the OBD-II service port Schrader core and cap]. * If the vehicle being tested does not have an EVAP service port, then access the EVAP system at the purge valve line that leads to the charcoal canister.

Lets do a step by step EVAP test. Remember that you must use nitrogen! 1. Connect the red lead to positive on battery. 2. Connect the black lead to chassis ground. A low battery will cause the Testers green Power light to blink. See Trouble Codes in your Operator Manual. Click here for next screen With power leads connected, the green light should be ON.
For the purpose of this presentation, we will use the.040 standard. 1.Position the Testers selector switch to the.040 calibration. 2.Turn the Tester ON. 3.Set the Pass / Fail mark by using your thumb to align the red pointer flag with the ball. Now the red flag is set to equal a.040 leak and it is calibrated for that vehicle. Remember to calibrate for.040 or.020 before each test. Click here for next screen Power ON Check Oil
Use scantool and close Vent Solenoid Click here for next screen If scantool doesnt close vent solenoid, refer to Tech Tip Booklet Vent Solenoid NO - OFF To activate vent solenoid Push YES to turn ON Push NO to turn OFF TPS 2.5V FTL 58%
At first the ball will go to the top of the flow meter. The ball will slowly drop until it no longer goes down. 3. Once the ball stops moving downward, check the alignment with the red flag. If the ball is below the red flag, the leak(s) are less than.040; PASS If the ball is above the red flag, the leak(s) are greater than.040; FAIL Go to Phase Two. Five minutes after turning the Tester ON, it will turn off automatically. 1. Set selector switch to TEST. 2. Close EVAP vent solenoid. 3. Turn the Tester ON. Phase One Click here for next screen Power ON Check Oil
Five minutes after turning the Tester ON, it will turn off automatically. Click here for next screen Power ON Check Oil Phase Two 1.Set selector switch to SMOKE. 2.Turn the Tester ON. 3.Look for Smoke and/or dye exiting the leak(s).
Look for the smoke or the ultraviolet-activated fluorescent dye Click here to Exit PowerPoint
