damage may occur if other headphone sets are used.
Finding Leaks
1. 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 (0.5 cm) of the possible
leak source.
2. Slowly (approximately 1 - 2 inches (2.5 - 5 cm) per second) move the probe past
each possible leak point.
NOTE: It is important to move the tip of the probe past the leak to get a
correct reading. D-TEK Select only responds to changes in
concentration of the refrigerant from the leak. Moving the probe
permits the instrument to respond properly to these changes.
3. When the instrument detects a leak source, its yellow LEDs will illuminate and
it will beep rapidly.
4. When D-TEK Select signals a leak, pull the probe away from the leak for a
moment, then bring it back to the location to pinpoint the leak.
5. If the concentration of the refrigerant gas is high, press the sensitivity switch to
change to the LOW sensitivity setting. The LOW sensitivity setting helps find the
exact site when a leak is large.
6. Once the leak source is isolated, return the sensitivity setting to HIGH to
continue using D-TEK Select.
7. When leak checking is complete, press the Power switch to turn D-TEK Select
OFF.
