AQUASONIC PRE-ENGINEERED WATER-
ATOMIZING FIRE SUPPRESSION SYSTEM
Design, Installation, Recharge, and Maintenance Manual
(Label No. F-2010225)

This manual is intended for use with the ANSUL AQUASONIC Pre-
Engineered Water-Atomizing Fire Suppression System.
Those who install, operate, recharge, or maintain this fire suppres-
sion system should read this entire manual. Specific sections will
be of particular interest depending upon one’s responsibilities.
Design, installation, recharge, and maintenance of the system
must conform to the limitations detailed in this manual and must be
performed by an individual who attended an ANSUL training
program and is trained to install, recharge, design, and maintain
the ANSUL system.
Fire suppression systems are mechanical devices that require
periodic care. Inspection and maintenance are vital steps in the
performance of your fire suppression system. As such, they must
be performed by an authorized ANSUL distributor in accordance
with this manual as well as NFPA 750 "Standard on Water Mist
Fire Protection Systems" or equivalent national or international
standards. An inspection will provide reasonable assurance that
the fire suppression system is fully charged and operable, and will
vary in frequency from hourly to monthly, based on the needs of
the situation. To provide maximum assurance that the fire suppres-
sion system will operate effectively and safely, maintenance must
be conducted at six-month intervals, or earlier if the situation
dictates.

SKID ASSEMBLY
The AQUASONIC Skid Assembly is a self-contained assembly
consisting of a 50 US gal (189.3 L) water tank, three 561 ft3
(16 m3) regulated nitrogen cylinders, and the necessary valving for
tank blow-down. Components are fabricated on a rugged skid
assembly.
The assembly is compact and can be easily positioned in any
desired location. Must specify ANSUL AUTOMAN II-C Release
(Part No. 17728) or AUTOMAN II-C Explosion/Weather-Proof
Release (Part No. 35623).
Part No. 303.211.002
FIGURE 3

REGULATOR
The AQUASONIC Skid Assembly contains one high-flow regulator.
The regulator is factory set to provide a delivery pressure of 125
psi (8.3 bar), allowing the proper nitrogen pressure to discharge
the water from the tank to the atomizer. It also allows the neces-
sary nitrogen pressure to flow directly to the atomizer to activate
its advanced atomization technology.

50 US GALLON (189.3 L) WATER TANK ASSEMBLY
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 pres-
sure 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 posi-
tioned for optimal flow, containing a Y strainer which will reduce the
number of foreign particles in the water stream reaching the atom-
izers. 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.
Part No. 435764
FIGURE 5
CV-98 VALVE / CYLINDER SHIPPING ASSEMBLY
The cylinder is factory filled with nitrogen to a nominal pressure of
2900 psi (200 bar). Multiple cylinders can be manifolded 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 VALVE
The CV-98 valve has a ten 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 external seal is broken, the warranty is
voided.
Note: Use Flexible Discharge Bend, Part No. 427082, when attaching
valve to supply pipe or manifold.

CYLINDER BRACKETING
The cylinder bracketing is designed to rigidly support the installed
nitrogen agent cylinders. The bracketing components 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.
