8.0 Maintenance
Avoid spilling liquids onto the unit, or it may malfunction. If a liquid is spilled onto the unit, turn
off the power immediately, remove heavy liquids with a dry towel, and let the unit sit until the liquid
dries. Dust and debris can enter the probe tip of the leak detector and, over time, can clog the small-
bore tubing inside the unit. To prevent this, clean the probe tip periodically. To clean the probe tip,
unscrew the cap to expose the brush (Figures 2 and 3). Gently clean the probe using a small brush or
your fingers to remove dust and debris, then replace the cap. Do not use liquids to clean the probe.
Liquids can damage the leak detector if drawn in through the probe.
Information on where to have the unit sent for maintenance or service* is listed at the end of this
document.
