Apply vacuum slowly and continuously while watch-
ing the gauge. The vacuum should stabilize momen-
tarily at 0.8 - 2.1 kPa (6 - 16 mmHg, 0.2 - 0.6 in.Hg).
lf the vacuum stabilizes (valve opens) below
0.8 kPa {6 mmHg, 0.2 in.Hg) or above 2.1 kPa
(16 mmHg, 0.6 in.Hg), install a new valve and retest.
Move the vacuum pump hose from the vacuum fit-
ting to the pressure fitting, and move the vacuum
gauge hose from the vacuum side to the pressure
side as shown.
Slowlv pressurize the vapor line while watching the
gauge. The pressure should be stabilize momentari
ly above 1.0 kPa (8 mmHg. 0.3 in.Hg).
. lf the pressure momentarily stabilizes (valve
opens) above '1.0 kPa (8 mmHg, 0.3 in.Hg), the
valve is OK.
. lf the pressure stabilizes below 1.0 kPa (8 mmHg,
0.3 in.Hg), install a new valve and retest.
Apply vacuum slowly and continuously while
watching the gauge. The vacuum should stabilize
momentarily at 0.7 - 2.0 kPa (5 - 15 mmHg, 0.2 - 0.6
in.Hg ).
lf the vacuum stabilizes (valve opens) below
0.7 kPa (5 mmHg,0.2 in.Hg) or above 2.0 kPa
(15 mmHg, 0.6 in.Hg), install a new valve and retest.

ting to the pressure fitting, and move the
gauge hose from the vacuum side to the

PRESSURESIDE
Slowly pressurize the vapor line while watching the
gauge. The pressure should stabilize at 1.3 - 4.7 kPa
(0 - 35 mmHg, 0.4 - 1.4 in.Hg).
. It the pressure momentarily stabilizes (valve
opens) at 1.3 - 4.7 kPa (10 - 35 mmHg, 0.4 - 1.4
in. Hg), the valve is OK.
. lf the pressure stabilizes below 1.3 kPa (10 mmHg,
0.4 in.Hg) or above 4.7 kPa (35 mmHg. 1.4 in.Hg),
install a new valve and retest.
