tions. Deep vacuums help remove
non-condensable gases that can
cause problems in a system.
There are many ways to hook up to
the system, Fieldpiece recommends
using a SCRT and the shortest vacuum
rated hoses possible. Fewer connec-
tions reduce the potential for leaks.

ing to the Schrader Core Removal Tool or an unused
service port.
2. Hold for 1 second to power ON the SVG3.
3. The top display shows the pressure/vacuum in
microns of mercury.
4. The bottom display shows how much the measure-
ment is increasing or decreasing (± microns of
mercury per minute).

Description
Proper evacuation of any system
button for 1 second. that has been exposed to atmosphere
is critical to ensure proper operation
and the SVG3 is the Right Tool to help
HVACR Professionals verify that they
reach proper vacuum levels. The easy-
view hook and backlight make the
SVG3 display easy to see in low vis-
ibility situations and the ruggedized
case is built to withstand the rigors
of field use.
To minimize leaks by reduc-
ing connections, the SVG3 has a
schrader depressor so you can
connect it directly to the service port
or your valve core removal tool.
With the built in Hi and Lo Alarm
C-Tick (N22675)
functions and the Rate Indication on
the bottom display to help the user,
CE
the HVACR Pro can do more because
he can be confident that he is doing
WEEE
the job right the first time.

How to Activate the Alarms
1. Press ALARM to activate low alarm.
2. Press ALARM again to deactivate low alarm and
activate high alarm.
3. Press ALARM again to deactivate high alarm and
return to normal mode.
How to Set the Alarms
The default low (500 microns) and
high (1000 microns) alarm values can
easily be set to your desired levels.
1. Hold ALARM for 1 second to enter alarm set mode.
The first digit of LO alarm will blink.
2. Use arrow buttons to change value. Press ENTER to
lock in a digit and move to the next digit. Repeat
for all LO alarm digits.
3. When LO alarm is complete, the first digit of HI alarm
will blink. Use arrow buttons to change value. Press
ENTER to lock in a digit and move to the next digit.
Repeat for all HI alarm digits.
4. When all digits of HI alarm are locked in you will
automatically exit alarm set mode and your
customized alarm values will be saved.
Note: Anytime while in alarm set mode, you can press
ALARM to toggle between alarm HI set and alarm
LO set. Hold ALARM to exit alarm set mode and
save at any time.

Vacuum Tips
Follow all manufacturer's evacu-
ation procedures over those in this
manual in regards to specifications on
how to evacuate systems. To achieve
a deep vacuum efficiently Fieldpiece
recommends the following practices.
1. Remove Schrader cores and core depressors from
the service ports using a valve core removal tool
(purchased separately).
2. Use the shortest vacuum rated hoses with the
largest diameter available.
3. Inspect rubber seals at both ends of your hoses for
damage that may result in leakage.
4. Avoid using hoses with low loss fittings when
evacuating a system.
