Charge main accumulator.
CAUTION
Ensure regulator valve is fully backed off to relieve tension on diaphragm. Failure to
comply may result in damage to equipment.
NOTE
Rapid pressurization will cause an inaccurate pressure reading due to heating of nitrogen
gas. Always pressurize slowly.
a.
Adjust regulator valve (Figure 36, Item 3) on nitrogen tank (Figure 36, Item 1) to 1,750-1,850 psi
(12,066-12,756 kPa).
b.
Open shutoff valve (Figure 36, Item 4).
c.
Read pressure measuring device (Figure 36, Item 5).
d.
When pressure reaches 1,750-1,850 psi (12,066-12,756 kPa), close shutoff valve (Figure 36, Item 4),
nitrogen tank valve (Figure 36, Item 2), and accumulator charge valve (Figure 36, Item 6).
e.
Wait 15 minutes and open charge valve (Figure 36, Item 6).
f.
Read pressure measuring device (Figure 36, Item 5) to determine if accumulator can retain charge.
