Getting Started with the EELD601
After you remove your EELD601 from
the box, check to make sure you have
all accessories shown below.

Depending on the test you are performing, connect either an inert gas,
such as Nitrogen, or shop air supply line to the EELD601 waterseparator / filter connection located on the back of the tester
Be sure the supply pressure to the tester is between 50 psi and 150 psi
When testing EVAP systems: Connect the tester to an inert gas, such as nitrogen.
When testing systems other than EVAP: Connect the tester to shop air.

The EVAP port adaptor is used
to connect to the vehicles EVAP
service port.

The Schrader removal tool is
used for taking the core out of
the EVAP service port.
No. WVA-09
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.
http://www.sae.org/technical/papers/2007-01-1235
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 don’t 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 CAN’T 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,don’t 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.

Purge Valve
If the car you are working
on doesn’t have an EVAP
service port Click here and
follow this procedure.
Note: See Tech Tip Booklet for more details.
Insert smoke supply hose into EVAP
system line going to the charcoal canister.
Note: This does NOT test the purge valve for leaks!
To Charcoal Canister / Fuel Tank
Let’s 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.
With power leads connected, the green light should be ON.
A low battery will cause the Tester’s green Power light to blink.

See Trouble Codes in your Operator Manual.
Press and release the ON/OFF
button to active the EELD601
The tester’s Smoke light
will come on, indicating
smoke production
The timer will automatically turn OFF in
5-minutes. To turn the tester OFF before the
5-minutes are up, simply press the ON / OFF
button again.

Notice that at the beginning of the test procedure,
the flow meter’s-ball will go to the top of the flow
meter scale
This indicates two things;
A) The EVAP system is being filled and
B) There are no restrictions in the EVAP system
at this time.
Note:
If the ball initially never goes to the top of the
flow meter, this indicates a restriction in the EVAP
system.
 Did you remember to remove the Schrader valve
from the EVAP service port?
 Do you have your nitrogen supply turned on?

Now close the vehicle’s EVAP System Vent Solenoid.
Usually in less than 60 seconds of activating or closing
the vent solenoid (depending on the capacity and fuel
level) the flow meter’s indicator-ball will fall within the
meter’s visible scale.
Continue to fill the system until the ball stops
descending (this could take an additional two minutes).
Once the meter's indicator-ball has stopped
descending, align the flow meter’s red flag to the
indicator-ball. If the ball descends to the bottom of the
meter, this indicates the system has NO leak.

However, if the red flag indicates a leak greater than
the allowable standard, continue to introduce smoke
into the system and look for the smoke exiting the
leak.
