User's Manual

INTRODUCTION
The ATD3699 features a long life heated sensor technology that is
designed to detect the more current and difficult HFC refrigerants
such as R-134a, R-410a, R-407c, R-507, and R-404c in addition to
all HCFC (R22) and CFC (R12) refrigerants including SNAP
approved hydrocarbon blends.
The ATD3699’s unique digital leak size indicator takes the
guesswork out of whether or not to repair a small leak. The digital
display is independent from the audio alarm and sensitivity level,
allowing the precise pinpointing of the leak source.
The ATD3699 does not require rechargeable batteries.

Cross Sensitivity to Automotive Chemicals
Some automotive solvents and chemicals have similar hydrocarbon properties as R134a and
may elicit a positive response (<30 seconds) from the ATD3699
. Before leak checking, clean
up any chemicals in the list below that elicit a positive response.
