Quick Start

1. Power on your SVG3 by holding the

button for 1 second.

2. Connect to system directly to an

unused service port, a Schrader core

removal tool (SCRT), or via hoses.

3. View vacuum in microns of mercury

on the top line and rate of change

(±microns per minute) on the bot-

tom line.

Description

Proper evacuation of any system

exposed to atmosphere is critical to

ensure efficient operation and the

SVG3 is the right tool to help HVACR

professionals verify they reach proper

vacuum levels. See your vacuum

measurement clearly and easily with

the newly designed easy-view hook

and backlight. SVG3 is built for eld

use with its ruggedized rubber case.

Reducing connections mini-

mizes leaks, so the SVG3 has

a female 1/4" flare fitting with

schrader depressor so you can

connect it directly to a service port or

your valve core removal tool.

Be alerted when you've reached

your desired vacuum levels with built

in Hi and Lo Alarm functions. Check for

leaks with rate indication in microns

per minute. The HVACR professional

can do more with condence that he

is doing the job right the rst time.

How to Use

Normal Mode

Measure deep vacuums to

monitor your system evacua-

tions. Deep vacuums help remove

non-condensable gases that can

cause problems in a system.

There are many ways to connect to

the system, Fieldpiece recommends

using a SCRT and the shortest vacuum

rated hoses possible. Fewer connec-

tions reduce the potential for leaks.

1. Connect to system. Techs typically prefer connect-

ing to the Schrader Core Removal Tool (SCRT) or an

unused service port.

2. Hold for 1 second to power ON the SVG3.

3. The top display shows the vacuum in microns of

mercury.

4. The bottom display shows how fast the measure-

ment is increasing or decreasing (± microns of

mercury per minute).

Low and High Alarms

Be alerted when you've reached your

desired vacuum levels. Work on other

tasks at the jobsite and let SVG3 alert

you when the system is ready.

Activate the low alarm (default 500

microns) to alert when the vacuum has

dropped to your desired micron level.

Activate the high alarm (default 1000

microns) to see how long it takes the

system to stabilize after the vacuum

pump has been isolated. If the system

does not stabilize over time, you may

have a leak in the system or your con-

nections.

The stopwatch will start when an

alarm is activated. It will restart when

the low alarm has been reached to show

how long you've pulled a vacuum after

reaching your desired micron level. The

stopwatch will stop when the high alarm

has been reached to show how long it

took to rise to your high alarm value.

When an alarm is activated the UP or

DOWN ARROW toggles the stopwatch

and rate of change (± microns per min-

ute) display.

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 real time mode.

How to Set the Alarms

The default low (500 microns) and

high (1000 microns) alarm values can

easily be set to whatever you want.

1. Hold ALARM for 1 second to enter Alarm Set Mode.

The rst digit of LO alarm will blink.

2. Use ARROWS to change the blinking number. 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 rst digit of HI alarm

will blink. Use ARROWS to change the blinking

number. 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.

Note: "Err" will show if you try to set the HI alarm

lower than the LO alarm, or the LO alarm higher

than the HI alarm.

Vacuum Tips

Follow all manufacturer's evacu-

ation procedures over those in this

manual in regards to specications on

how to evacuate systems. To achieve

a deep vacuum eciently 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 ttings when

evacuating a system.

5. Avoid over-tightening the female are tting of

the SVG3. Over-tightening may cause the rubber

gasket to wear more quickly and create leaks. It is

not necessary to over tighten SVG3 to the extreme

to create a good seal.
