• Place the tip of the leak-detector probe as close
as possible to the site of the suspected leak. Try
to position the probe within 1/4 inch (6 mm) of
the possible leak source.
• Slowly move the probe past each possible
leakage point.
• When the instrument detects a leak source, the
audible tone will alarm. Additionally, the visual
indicators will light from lower to higher; Green
LED then Orange LED then Red LED (highest
concentration) as increasing of level indicate that
the location is close to the source.
When the Instrument signals a leakage, pull the probe
away from the leak for a moment, then bring it back
to pinpoint the location. If the refrigerant leak is large,
setting the sensitivity switch to LOW will make it easier
to find the exact site of the leak.
• Return the sensitivity switch to HIGH before
searching for additional leaks.
• When you’ve finished leak-testing, turn OFF the
instrument and store it in a clean place, protect
the leak detector from possible damage.
