The AQUASONIC System agent tank is a 50 US gal (189 L)
capacity water tank featuring a 0.17 in. (4.3 mm) thick
ASME pressure vessel that is certified to 150 psi (14.8 bar).
This vessel is both ASME and 97/23/EC (PED) CE marked.
The tank features a 2 in. (5.1 cm) fill opening; the tank also
has an outlet that is positioned for optimal flow, containing a
Ystrainer which will reduce the number of foreign particles
in the water stream reaching the atomizers. The tank is
constructed from 304L stainless material to help ensure
rust-free performance.
Note: Mounting feet will accept up to a 1/2 in. (12 mm)
diameter bolt.

Description
The cylinder is factory filled with nitrogen to a nominal pres-
sure of 2900 psi (200 bar). Multiple cylinders can be mani-
folded together to obtain the required quantity of nitrogen. The
cylinder valve can be actuated electrically, pneumatically,
and/or manually with approved valve actuation components.
All valves are equipped with an anti-recoil feature.
The cylinders are shipped with a maintenance record card
and protective shipping cap attached to the threaded neck
of each cylinder. This cap entirely encloses and protects the
valve while in shipment.
CV-98 INERGEN Valve
The CV-98 valve has a ten (10) year warranty. The valve
requires no internal maintenance.The valve is sealed
closed and must not be disassembled. If there is ever a
malfunction of the CV-98 valve, the complete valve must be
sent back to ANSUL for warranty replacement. If the exter-
nal seal is broken, the warranty is voided.
Note: Use Flexible Discharge Bend, PartNo. 427082, when attaching
valveto supply pipe or manifold.

Cylinder Bracketing
Description
The cylinder bracketing is designed to rigidly support the
installed nitrogen agent cylinders. The bracketing compo-
nents are constructed of heavy structural steel. Bracket
assemblies are available in modules for two to six cylinders
and can also be connected together for any combination
over six. Bracketing can be assembled to support single row,
double row or back-to-back rows of cylinders. Bracketing
components are painted with a red enamel coating. Uprights
and back frame assemblies can be bolted or welded
together, whichever makes the installation more
convenient.

AUTOPULSE Control System
002195

The ANSUL AUTOMAN II-C Releasing Device consists of a
metal enclosure which contains a spring-loaded puncture
pin release mechanism, actuation cartridge, electrical
circuitry, and an input/output terminal strip for making elec-
trical connections. The ANSUL AUTOMAN II-C Releasing
Device provides automatic pneumatic actuation of the
AQUASONIC System. When wired to an AUTOPULSE
Control System, it will provide supervised electric detection
and release. The ANSUL AUTOMAN II-C Releasing Device
also provides manual actuation using the strike button on
the release enclosure or with the optional remote manual
cable pull station. When an AUTOPULSE Control System is
used, manual actuation is accomplished using an electric
manual pull station.
The ANSUL AUTOMAN II-C Releasing Device requires an
LT-10-R nitrogen cartridge for system actuation. Cartridge
must be ordered separately.

The remote actuator is a device that allows for system actu-
ation from a location either near or far from the
AQUASONIC System Supply. Two types of actuators are
offered. One requires an LT-10-R nitrogen cartridge, and the
other requires an LT-30-R nitrogen cartridge. When actu-
ated, the cartridges will supply pressure to the CV-98 valve
pilot actuation port on the pilot cylinder, allowing nitrogen to
flow. Cartridge must be ordered separately.

Booster Actuator
Description
The Booster Actuator, Part No. 428949, is used when elec-
tric actuation is required on the 1 in. selector valve, 2 in.
selector valve, or the CV-98 cylinder valve. The actuator
mounts directly to the component and then an HF electric
actuator mounts to the top of the booster actuator.
The Booster Actuator requires resetting after actuation. A
Reset Tool, Part No. 429847, is available for this use.

Description
Electrical actuation is accomplished by an HF electric
Actuator, Part No. 73327, interfaced through an
AUTOPULSE Control System. This actuator can be used in
hazardous, indoor environments where the ambient temper-
ature range is between 0 °F to 130 °F (–18 °C to 54 °C).
The HF electric actuator meets the requirements of N.E.C.
Class I, Div. 1, Groups B, C, D and Class II, Div. 1, Groups
E, F, G. A maximum of two HF electric actuators can be
used on a single AUTOPULSE release circuit. When utiliz-
ing only one HF electric actuator, an in-line resistor, Part
No. 73606, is required in the supervised release circuit.
In auxiliary or override applications, a manual-local override
valve actuator or a manual cable pull actuator can be
installed on top of the HF electric actuator by removing the
safety cap.
An arming tool, Part No. 75433, is required to reset the
actuator after operation. The actuator contains a standard
1/2 in. threaded female straight connector for electrical
conduit hookup.

Description
The manual lever release actuator provides a manual
means of actuating cylinder valves and selector valves. This
can be accomplished by direct manual actuation of its pull
lever or cable actuation when used in conjunction with a
remote manual pull station. When used with a remote man-
ual pull station, the pull station must contain the compo-
nents necessary to meet the actuator lever traveling
requirements of 7 in. (178 mm).
The actuator is shipped with ring pin and chain attached. If
the ring pin is not required, it must be removed. Failure to
remove the ring pin/chain assembly will prevent system
actuation if a remote cable pull actuation system is
employed and the ring pin is accidentally installed in the
actuator.
Four actuators are available. Each is designed for a specific
component.
Note: For use with systems without selector valves.

Flexible Discharge Bend
Description
The valve Flexible Discharge Bend (Part No. 427082) is a
5/8 in. (1.59 cm) ID extra-heavy flexible hose which
connects the valve discharge outlet to the fixed piping or
header manifold. The discharge bend has a special female
thread for connecting to the valve outlet and a male 1/2 in.
NPT thread for connecting to the fixed piping or manifold.
The discharge bend will withstand a pressure of 9000 psi
(621 bar). Its flexible connection allows for easy alignment
of multiple cylinder banks to fixed piping. Each bend has a
built-in check valve that prevents loss of agent should the
system discharge while any cylinder is removed.
The equivalent length of this hose is equal to 18 ft (5.5 m)
of 1/2 in. Sch. 40 pipe.
