Accumulator - Charging (H.40.B.30 - F.60.A.30)

435, 445, 445CT

NOTE: Check the pressure in the accumulator according to the instructions in this section. Keep the nitrogen
charging kit connected to the accumulator.
1. Turn valve (A) counterclockwise until it is closed.
Open valve (B). Close valves (C) and (D).
2. Turn the stem out of the valve (F) until the stem
stops moving. Disconnect valve (F) from the valve
stem on the accumulator.
3. Connect the nitrogen charging kit to a dry nitrogen
tank.
4. Slowly turn valve (A) clockwise. Read gauge (E)
until the pressure is 275 - 325 psi (1897 - 2241 kPa,
19 - 23 bar). Stop turning valve (A).
5. If the pressure increases above 325 psi (2241 kPa
23 bar), quickly open and close valve (D) and read
gauge (E). If the pressure is still too high, slightly
turn valve (A) counterclockwise and quickly open
and close the valve (D). The pressure shown on
gauge (E) is the charge pressure.
6. Connect valve (F) to the valve stem on the
accumulator. Turn the stem into the valve (F) until
the stem stops moving and open valve (D) to charge
the accumulator.
7. After the accumulator stops charging, turn the stem
out of valve (F) until the stem stops moving.
