NOTE
 Make sure the air conditioning system is switched off. How-
ever, there must be a minimum of 3.5 bar in the system to be
able to find leaks. If the minimum pressure is not reached, you
will need to use other ways to detect leaks.
 Make sure that any other gases or chemicals are not released
into the area being searched which the device will respond to.
Some common vehicle cleaners contain chemicals or exude
gases. Remove dirt and any chemicals that could cause a
false reading.
 Only carry out leak detection when the motor is switched off.
1. Check all visible surfaces of the air conditioning system for any loss of
lubricant, damage and corrosion.
2. Switch on the leak detector with the start button (fig. 2 4, page 2)
(chapter "Switching on the leak detector" on page 7).
✔ The device warms up briefly.
3. Select a suitable sensitivity level for the size of the leak anticipated.

NOTE
 If the leak detector has already triggered an alarm due to a
major leak, ensure adequate ventilation so that minor leaks
can also be detected.
 If a leak has been identified at the lowest sensitivity level, run
another scanning process with the next level of sensitivity to
determine the size of the leak more precisely.
4. Insert the sensor head as close as possible, and at low speed (3
cm/sec), to the components that are to be examined for leaks.
5. Remove the sealing caps of the service connections and check the
service connections for tightness.
6. Make sure you perform the test without any interruptions.
✔ When a leak is detected, a beep is emitted.
