fT-FITTING
Apply vacuum slowly and continuously while watch-
ing the gauge.
Vacuum should stabilize momentarilv at 5-15
mmHg (0.2-0.6 in. Hg).
a It vacuum stabilizes (valve opensl below5mmHg(O.2 in.Hg) or above I 5 mmHg (O.6 in.Hg), install
a new valve and retest.
Move vacuum pump hose from vacuum to pressure
titting, and move vacuum gauge hose trom vacuum
to oressure side as shown.
Pressure should stabilize at 1O-35 mmHg (0.4- 1 .4
in. Hg).
a lf p.essure momentarily stabilizes {valve opensl
at 1O-35 mmHg (O.4- 1.4 in.Hg), the valve is
oK.
a lf pressure stabilizes below 10 mmHg {O.4 in.Hg)
or above 35 mmHg (1 .4 in.Hgl, install a new valve
and retest.
