PLACE SYSTEM BACK IN SERVICE – CV-98 VALVE
Recharge procedures for cylinder assemblies utilizing the
CV-98 valve with an HF electric actuator requires normal
cylinder recharging.
RECHARGE CYLINDER
The following steps must be followed when removing dis-
charged cylinders from the system:
1. Disconnect the flex bend from the cylinder(s) outlet.
2. Remove all actuators from the cylinder valves.
3. If necessary, remove 1/4 in. actuation hose, elbow, and
adaptor from pneumatic actuation port.
4. If necessary, install plug, Part No. 42411, into pneu-
matic actuation port and wrench tighten.
5. With cylinder secured in bracket, relieve any remaining
pressure in the cylinder by completing the following:
a. Make certain discharge cap IS NOT on valve outlet.
See Figure 1.

b. Attach bleed down device, Part No. 426028, to valve
fill inlet. See Figure 2.

c. Bleed residue pressure from cylinder. Make certain
cylinder is completely empty before removing bleed
down device.
d. With cylinder completely empty, remove bleed down
device and install safety shipping cap.
e. Complete Steps a. through d. on all discharged
cylinders, both pilot and slave.
6. Determine if discharged cylinder requires hydro-testing
prior to being recharged. Note last hydro date on cylin-
der collar. If cylinder does not have a star stamp, it
requires hydro 5 years from last hydro date. If cylinder
has a star stamp, it requires a hydro-test 10 years from
last date.
NOTICE
Empty cylinders must be sent to an
authorized Ansul recharge facility for
filling. Contact Ansul Technical Services
Department for any information needed
concerning authorized fillers.

CAUTION
!
Attach bleed down device, Part No. 426028, to fill
inlet of discharged cylinders only. Never attach this
device to fully charged cylinders as this will cause
high pressure to discharge out of the fill inlet. Also,
install device hand tight only. Do not wrench tighten.
NOTE: Bleed-down device, Part No. 416656, CAN-
NOT be used on CV-98 valve.
