Basic Testing Procedure
1. Connect Tester to shop air. See Optional Gas Source below.
2. Connect Tester’s Red power cable to vehicle’s 12 Volt DC battery
positive terminal.
>
Battery must be in good condition and fully charged!
3. Connect Tester’s Black cable to vehicle’s chassis ground. Do NOT
connect the black cable to battery ground because a spark in the vicinity
of the battery can cause an explosion!
(Figure 2)
4. Observe that the Green Power indicator lamp on the Tester is ‘ON’
confirming that you are properly connected.
>
A blinking green power lamp indicates insufficient battery power to the
Tester.
5. Connect smoke supply hose to system being tested.
6. Flow Control Valve must be in Full Open position.
(Figure 3)
7. Press START button and fill system with smoke.
>
Whenever possible it is best to ‘purge’ the ‘non-smoke’ air out of the system
being tested in order to quickly fill the system with smoke
.
>
Smoke production is on 5-minute timer
.
8. Use white light supplied and look for exiting smoke or use ultraviolet light
supplied to look for fluorescent dye deposit at exact location of a leak.
>
The longer smoke is allowed to exit a leak, the more fluorescent dye will be
deposited at leak locations
.
