WARNING
Exposure to high concentrations of CO2 or refrigerants is dangerous and can
be life-threatening.
The instrument is not for use in toxic or hazardous environments. It is not a personal
protection or life-saving device. Always exercise extreme caution in potentially toxic or
hazardous environments.
WARNING
This product is not intrinsically safe and should not be used in the presence of

3 The upper leak detection limit is not specified by INFICON as there is no upper limit
to the size of the leak the detector is able to detect.
4As no 50 g/yr. leak standard was available during testing, a 32 g/yr leak standard was
substituted.
SAE Applications SAE standards J2791 (R-134a) and J2913 (R-1234yf) specify sensitivity to the
following leak sizes for the corresponding settings below. Super sensitivity is more
sensitive than what is required by SAE for leak checking in a clean environment (free
of background refrigerant). If leak checking in a contaminated environment (high
background refrigerant), switch to Super sensitivity.

leak test procedure
Always leak test with the engine off.
1.
Charge the system with sufficient refrigerant to have a gauge pressure of at
least 340 kPa (50 psi) with the system off. At ambient temperatures below 15 °C
(59 °F) leaks may not be measurable because the pressure may not be
reached.
2.
Visually trace the entire refrigerant system, and look for signs of air conditioning
lubricant leakage, damage and corrosion on all lines, hoses and components.
Check each questionable area with the detector probe, as well as all fittings,
hose-to-line couplings, refrigerant controls, service valves with caps in place,
brazed or welded areas, and areas around attachment points and hold-downs
on lines and components. If looking for an apparently larger leak, check first at
the medium (7 g/year) or low (14 g/year) sensitivity setting.
3.
Always follow the refrigerant system around in a continuous path so that no
areas of potential leaks are missed. If a leak is found, always continue to test
the remainder of the system.
4.
Recheck the service valves with the caps removed. Blow shop air over the
service valve to clear the immediate area. Check with a detector on the medium
sensitivity setting (7 g/year).
5.
Move the detector at a rate of no more than 75 mm/s (3 in./s) and as close as
possible to 9.5 mm (3/8 in.) from the surface, completely encircling each test
position (switch, sensor, refrigerant tubing connection, etc.).

6.
Slower movement and closer approach of the probe normally improves the
likelihood of finding a leak. However, detectors made to meet this standard are
based on air sampling from the 9.5 mm (3/8 in) distance. A retest 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 making physical contact with a joint,
as it was moving. Repeat with a moving probe test at that location, taking care
to maintain the small gap (9.5 mm or 3/8 in.) to confirm that the leak is of
repairable size. Checking with the medium sensitivity setting (7 g/year) after
finding an apparent leak with the high sensitivity setting (4 g/year) also may be
helpful.
