Tracer TP-9365 PRO-Vac AM08048 - Manual (Page 4)

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
as 100 X1000 .
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
