1. Does the UV scanner light work better than an electronic leak detector?
No one detection system is better for all situations. However, with a UV lamp, you can scan a system more quickly and moving air is never a problem. Solutions also leave a telltale mark at every leak site. Multiple leaks are found more quickly.

2. How is the solution different from visible colored dyes?
Unlike colored dyes, YELLOW JACKET fluorescent solutions mix completely with oil and do not settle out. Lubrication, cooling capacity and unit life are not affected. And there is no threat to valves or plugging of filters. The solutions will also work in systems containing Dytel.

3. In a system with a mix of mineral and alkylbenzene oil, which scanner solution should be used?
Base your choice of solution on whatever oil is present in the larger quantity. If you don't know which oil is in greater quantity, assume alkylbenzene.

4. How do I test the system?
Put solution into a running system to be mixed with oil and carried throughout system. Nitrogen charging for test purposes will not work since nitrogen will not carry the oil. To confirm solution in the system, shine the lamp into the system's sight glass. Another way is to connect a hose and a sight glass between the high and low sides, and monitor flow with the lamp. The most common reason for inadequate fluorescence is insufficient solution in the system.

5. What's the most effective way to perform an acid test?
Scanner solution affects the color of the oil slightly. Use a 2-step acid test kit, which factors out the solution in the oil, giving a reliable result.
