This manual contains operating instructions for four models. Basic opera-
tion of all units is the same. Individual model features and specific operat-
ing characteristics are noted within the text as applicable.
Refer to the packaging or unit labels for identification of your model. Your
new unit has been specifically designed to meet both current and future
leak detection needs by providing you with the ability to detect a multitude
of refrigerants. See the Applications section on page 7 for more detailed
information on detectable compounds.
Just turn the unit on and begin searching for leaks. A computer-like
beeping signal will increase in frequency as the leak source is approached.
In situations where the area is heavily contaminated with gas the unit can
be adjusted to the contaminated atmosphere to prevent misleading
readings.
For best results please read this manual carefully before attempting to
operate the unit.
