Introduction
The Tracerline® PRO-Vac™ Vacuum/Micron Gauge is a digital
gauge designed to accurately measure vacuum levels during
evacuation of air conditioning and refrigeration systems from
atmosphere down to 1 micron (0.01 mbar, 1 Pa). It uses a
proprietary Pirani sensor, the most accurate sensor in its class.

Operating Instructions
1. Remove the battery access cover and install the 9-volt battery.
An indicator on the display will turn on when the battery needs
to be replaced.
2. Connect a dedicated or new charging hose to the PRO-Vac’s
fi tting.
a. A previously used hose may contain oil that could affect the
sensor performance.
b. Normal refrigeration hoses do outgas (leak) which may make
it diffi cult to measure below 250 microns. We suggest using
a metal braided hose for better accuracy.
c. We recommend using a hose no longer than 3 feet. A longer
hose may make the gauge unable to read lower vacuum
levels due to excessive outgassing.
3. Connect the other end of the hose directly to either the high
or low side of the system for most accurate readings. For
convenience, you can also connect the hose to one of the ports
on the vacuum pump itself. To connect the gauge in-line with a
manifold set or the vacuum pump, you will need a separate 1/4
inch male by 1/4 inch male by 1/4 inch female T fi tting.
Warning: Pressures greater than 150 psi can
damage the sensor. Be sure the system’s refrigerant has
been recovered before connecting the PRO-Vac.
4. Turn the PRO-Vac on by pressing the On/Off button. Readings
greater than 1500 will be displayed as 3 digits followed by the
X1000
indicator. For example, a reading of 100,000 is displayed
X1000
as 100
.
5. The PRO-Vac will turn off automatically after 1 hour when
the vacuum reading is above 30,00 microns The last reading
before auto shutdown and MEMORY are displayed for 5
seconds when the unit is turned back on. Auto shutdown
4
is disabled when the vacuum level is below 30,000 microns.
However, you can turn the PRO-Vac off or on at any pressure.
Vacuum Units Selection
The PRO-Vac can display vacuum in units of microns, mbar, or
Pascal. To change units, press and hold the power button for
3 seconds during power-up and the indicator for the active unit
fl ashes. Briefl y press the power button to select the desired units.
Press and hold the power button for 1 second to save the setting.
Quick Calibration
The PRO-Vac has a quick calibration feature to allow for
equalization to different atmospheric pressures. Press CAL to
activate. CAL fl ashes on the display and the reading stabilizes
at 760 x 1000. The gauge will maintain this reference point until
a new one is set. NOTE: Quick calibration is disabled at vacuum
levels below 100,000 microns.
Changing the Filter
The PRO-Vac is equipped with a special fi lter to protect the
vacuum sensor from oil and other contaminants. To change the
fi lter, remove the setscrew in the unit’s fi tting. See Figure 1. Use
an 11/16” wrench to stabilize the top portion of the fi tting. Then
twist off the lower portion of the fi tting using a 1/2” wrench. Use
needlenose pliers or a similar item to gently pull out the used
fi lter. Do not attempt to clean or reuse fi lters. Insert a new fi lter
with the thicker portion of the O-ring facing away from the
gauge’s body. Reattach the refrigerant fl are. Tighten the fi tting
with the wrenches and replace the setscrew to ensure vacuum
integrity.
