INTRODUCTION
Congratulations on your purchase of the Superior AccuTrak
®
Model VPE or
VPE-GN ultrasonic leak detector! The AccuTrak
®
VPE is just one model in
the AccuTrak
®
line of high quality ultrasonic instruments that are available
exclusively from Superior Signal Company LLC. The Superior AccuTrak
®
line
offers an incredible range of capabilities, using patented technology that
provides real-world performance far superior to any other instruments in their
class, yet at amazingly affordable prices.
That’s why we say:
You have to
Hear it to Believe it! With AccuTrak
®
you simply get the job done faster,
easier, and at a lower cost.
The Superior AccuTrak
®
Model VPE-GN is a special version of the VPE, with
all the same technology and specifications
–
plus the unique ability to place
the actual sensor head directly into hard-to-
reach places. This 9” flexible
GooseNeck allows you to find even the smallest leaks in blind spots behind
obstructions or inaccessible places inside machinery. The VPE-GN cannot
use the Touch Probe accessory to hear internal ultrasound, so references to
this capability / option in this manual do not apply to the VPE-GN instrument.
Also please note that the GooseNeck is NOT removable, and any attempt to
remove or modify the GooseNeck will cause damage and void the Warranty.
The AccuTrak
®
VPE is the only ultrasonic instrument specifically designed for
air-conditioning and refrigeration leak detection. Refrigeration is a unique field
that requires very high performance leak detectors. It requires both vacuum
and pressure leak detection at very low flow rates. Ultrasonic inspection is the
only test system that can simultaneously detect both. The AccuTrak
®
is a
unique solution to the many problems typically encountered with traditional
methods of leak detection. The instrument offers advantages which will result
in significant time and cost savings. The AccuTrak
®
VPE is the ideal tool for
detecting both vacuum and pressure leaks of any refrigerant. Because the
instrument detects sound, it is gas independent. This means the AccuTrak
®
can even detect dry nitrogen gas leaks.
Enjoy your new instrument! It will eliminate the many hours of frustration that
you have experienced while trying to locate a leak in a gas saturated area, on
a windy roof top unit, or on a system under negative pressure (vacuum). It will
also eliminate the need to use tracer gasses which can be ozone depleting
when vented. The AccuTrak
®
VPE is very easy to use because it uses a
totally different technology than the "sniffers" and torches that you probably
are used to. To eliminate any future frustration, please take a few minutes to
read this manual and understand the operation of the AccuTrak
®
