3. Always go through the complete CO2 refrigerant circulation
path so that no areas of potential leaks are missed. If one
leakage is found, continue to test the remaining part of the
system.
4. Re-check service valves with caps removed. Air cleans the
service valve to clear the immediate area and then check with
detector with medium sensitivity setting.
5. Move the detector at the speed no more than 75 mm / sec (3
in/sec) and as dose as possible to 6 mm (1ie) from the surface,
completely encircling each test position (switch, sensor,
refrigerant tubing connection, etc.).
6. Slower movement and closer approach of the probe normally
improve the possibility of finding a leak. However, detectors
made to meet this standard are based on air sampling from
the 6 mm (1/41. Re-test is advisable when a leak appears to be
found at the most sensitive settings, particularly if the probe
was in a static position on a joint or marking physical contact
with a joint as it was moving. Repeat the test by moving probe
around that location, taking care to maintain the small gap (6
mm / 1/41 to confirm the leak is of repairable size. Use of the
medium sensitivity of the detector, after finding an apparent
leak with the High sensitivity setting may also be helpful.
7. The leak detector is sensitive and can take up to 30 seconds to
clear after detecting a small amount of contaminant. It will
typically clear in 2 to 15 seconds.
When the source of the leak is detected, the detector may cause a
reaction. If the first green LED continues to flash it indicates that the
sensor is not restored to the best condition. Please wait a few
seconds to be restored.
