Flammable gases! The gases R152a, R290, R502, R600a and HFO-1234yf
may form explosive gas mixtures.
Care for sufficient ventilation and keep away from ignition source.

10 Maintenance
Sniffing
Keep probe in contact with the gas outlet until the measured
value is stable.
3 Maintenance
The calibrated test leak requires no maintenance.
When the calibration gas is used up (pressure < 0.5 bar) the
testleakhasto berefilledandcalibrated.Pleasecontactyour
nearest INFICON Service Center.
Notice: Ifthepressureis<0.5barapropercalibrationoftheleak
detector is not assured. Therefore an accurate
measurement of the test sample is not guaranteed.
3.1 Cleaning the outside
Forcleaningtheoutsideofthetestleak,aslightlyhumidcloth
should normally do.
Do not use under any circumstances any aggressive or scou-
ring cleaning agents.
