Smoke:
1. To pressurize a system with smoke. Use one of the two air sources, Internal Pump or Air/Inert Gas.
2. Press the SMOKE button and the unit will produce smoke. To stop the production of smoke, press the SMOKE button again.
Finding Leaks:
1. Once the system is pressurized with smoke, use the flashlight from the kit to search for leaks. If a leak is present the smoke will illuminate when the light passes
through the smoke.
Leak Decay Testing:
1. Pressurize the system and set the regulator to the desired pressure.
2. Cap the pressure in the system by turning the flow meter control knob clockwise until the flow meter is closed.
3. Observe the pressure reading on the pressure gauge. If the gauge does not lose pressure then there are no leaks present. If the gauge does lose pressure then a leak
exists. The flow meter will indicate the size of the leak.
4. Use the SMOKE to find the leak.
5. Repair and re-test until no more leaks are found.
DIAGNOSIS:
Note: Refer to the vehicle manufactures recommendation for the maximum pressure of each system that will be tested.
Intake Leaks:
1. Disconnect the intake air duct from the air filter box.
2. Insert the intake bladder or the cone adapter that is supplied with the kit into the intake duct.
3. Attach the intake bladder or the cone adapter to the smoke hose cone.
4. Pressurize the system by pressing the PUMP button or use external Air/Inert Gas..
5. Press the SMOKE button.
6. Use the flashlight to locate any leaks.
NOTE: Some vacuum hoses may need to be capped to find small or to isolate leaks.
NOTE: Some intakes may not be 100 percent sealed by design.
7. Repair and re-test until no more leaks are found.
Vacuum Lines and Vacuum Component Leaks:
1. Disconnect the vacuum line for the component or vacuum circuit that is to be tested.
2. Insert the smoke hose cone to the vacuum line.
3. Pressurize the component or circuit by pressing the PUMP button or use external Air/Inert Gas.
4. Press the SMOKE button.
5. Use the flashlight to locate any leaks.
Note: The air filter box may need to be sealed so that the circuit being tested does not back flow into the air filter box.
Note: Some vacuum hoses may need to be capped to find small or to isolate leaks.
Note: Some vacuum components may be not be 100 percent sealed by design.
6. Repair and re-test until no more leaks are found.
Exhaust Leaks:
1. Insert the cone adapter that is supplied with the kit into the tail pipe of the exhaust.
NOTE: If the vehicle has dual exhaust, use the cap plugs to seal the other tail pipe.
2. Pressurize the exhaust system by pressing the PUMP button or use external Air/Inert Gas.
3. Press the SMOKE button.
NOTE: Some smoke may be consumed by a hot catalytic converter.
4. Use the flashlight to locate any leaks.
NOTE: Exhaust leaks are easier to find when the exhaust system is at ambient temperature.
5. Repair and re-test until no more leaks are found.
Under the Dashboard Leaks:
1. Disconnect the vacuum line for the component or vacuum circuit that is to be tested.
2. Insert the smoke hose cone into the vacuum line.
3. Pressurize the circuit by pressing the PUMP button or use external Air/Inert Gas.
4. Press the SMOKE button.
5. Check the pressure gauge and the flow meter while cycling through the climate controls.
6. Changes in the pressure gauge or the flow meter readings will indicate which system is leaking.
7. Set the climate control to the system that is leaking.
8. Use the flashlight to locate any leaks.
9. Repair and re-test until no more leaks are found.
NOTE: The central locking can be checked in the same manner. Activate the control solenoids while smoke is being pumped into the system.
MAINTENANCE:
Cleaning the Flow Meter:
1. Disconnect the unit from the power supply.
2. Disconnect the unit from external Air/Inert Gas source.
3. Remove the screw from the bottom of the flow meter bracket.
4. Swing the flow meter out of the cabinet and unhook the bracket from the cabinet.
5. Disconnect the flow meter from the unit by disconnecting the two hoses that are attached to the back of the flow meter.
6. Remove the bracket from the back of the flow meter.
