Cautions and Usage Tips
To prevent personal injury and / or damage to vehicle or equipment:
• Many automotive manufacturers require the use of nitrogen to be used while testing the EVAP system.
This is because a high heat source or spark could ignite fuel vapours mixed with air. The Cool Smoke
does not use potentially hazardous high temperature glow plugs or resistance coils to create smoke.
However nitrogen should be used to reduce the ignition risk if other potential ignition sources are nearby.
The Cool Smoke can perform it’s functions using clean and dry conventional shop air.
• Use this equipment in the manner specified by the manufacturer.
• Understand operating procedures / Follow all safety precautions.
• Correctly connect power supply to battery and chassis ground. Top-off smoke-producing solution
throughout the year.
• Use only Cool Smoke Smoke Solution No. 400-1054. Altering the solution, hoses, cables or any other
replacement parts will void the warranty; may cause tester malfunction; may cause damage to
the vehicle, to property or may cause personal injury.
• To view the dye deposit, use the optional UV Phazer NEO ™ light. (PN: 413025)
• Wear yellow glasses that are provided with the UV light to view dye.
• Do not use with running vehicle engine.
• Do not perform test near source of spark or ignition.
• Never leave the tester’s hoses or power cables connected to the vehicle for extended periods of time if
tests aren’t being performed.
• The 12V DC battery source you use to power the tester must be in good condition and fully charged.
• Wear eye protection that meets OSHA standards.
• Tester input pressure must be 80-150 psi (5.5-10.3 bar)
Store and operate the tester in upright position.
TIPS:
• Whenever possible allow the system to vent as far away from where the smoke is being
introduced. This will purge the air and fill the system with smoke. Once the system is filled with smoke
close the vent and allow the system to be pressurized.
• When testing an engine’s intake or exhaust system for leaks, it is recommended that the engine be cold.
Small leaks may be sealed due to thermal expansion.
