(NEVER TURN <br />COUNTER CLOCK-WISJEI) <br />Re -test the leak detector and mate step through time. <br />If a 3 CPH leak is not detected, perform another adjustment and re -test. <br />You may have to perform this adjustment several times before the leak detector slows down <br />and detects the leak. <br />To explain what is occurring during the adjustment you should know that the piston assembly <br />consists of a piston, hollow shaft,spring, and: metering poppet. While turning the retaining nut <br />Of this assembly, you are turning the whole assembly, The metering <br />the metering pin of the leak detector while in the reset position and the leak sseea what <br />Pit sorcontacts. <br />The metering pin will never move. By changing the position of the metering poppet to the pin, <br />the flow rate will change when adjusting. This also changes the step through time of the leak, <br />detecto. <br />By adjusting to find a 3 GPH leak. we are reducing flow into the line to make the leak detector <br />more sensitive to finding a leak. <br />You may notice that when performing the adjustment, the step through time may start to speed <br />up. The slowest laosition may be 180 degrees from the fastest P <br />up, continue the adjustment and you will see the leak detector start to stow down n� is speeding <br />Always test for a 3 GPIH leak after each adjustment. Always adjust in a clock -wise <br />direction. <br />If this is the first time you have attempted to adjust a VMI leak detector, we ask thaw you call <br />Vrni (800 367-0185) for technical assistance. <br />$700 East Lo,i cWesa Drive, Pry Ott Valley, Arizona 86314 <br />800-357-0135 925-775-5191 F2x: 928-77:5,:5309 <br />Email: vmiCv3p0r1es5.CD1n Website: at=:va nrless.eom <br />
