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.

HF ELECTRIC ACTUATOR
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 environ-
ments where the ambient temperature 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.

LEVER RELEASE ACTUATOR
The manual lever release actuator provides a manual means of
actuating cylinder valves and selector valves. This can be accom-
plished by direct manual actuation of its pull lever or cable actua-
tion when used in conjunction with a remote manual pull station.
When used with a remote manual pull station, the pull station must
contain the components necessary to meet the actuator lever trav-
eling 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
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 pres-
sure of 9000 psi (621 bar). Its flexible connection allows for easy
alignment of multiple cylinder banks to fixed piping. Each bend has

The water tank pressurization hose (Part No. 72584) is a 1/2 in.
diameter flexible hose which connects the water tank to the regu-
lated water tank pressurization piping. This allows for easy
removal of the water tank fill connection for tank inspection and
filling.
The swivel adaptor (Part No. 25582) provides a swivel connection
which allows installation of the hose without twisting the hose.

HEADER VENT PLUG
The header vent plug is used to release low pressure build- up that
may occur in a closed system. The header vent plug must be
installed on every high pressure manifold where cylinders are
connected. The header vent plug must be installed on the cylinder
sides of the check valves on both main and reserve systems to
relieve any pressure that may leak past the check valve and acci-
dentally actuate the reserve system while the main system is
discharging.

The pressure trip is connected to the actuation or discharge line of
an AQUASONIC System. By either pneumatic or manual actua-
tion, the pressure trip can release spring or weight powered
devices to close doors and windows, open fuel dump valves, close
fire dampers or close fuel supply valves. The pressure trip is
constructed of brass with two 1/4 in. NPT fittings for connection to
discharge or actuation lines. The link on the pressure switch is
released either pneumatically, by agent discharge pressure; or
manually, by use of the pull ring. The link then releases the device
which performs the auxiliary functions.
Note: Operating pressure must be a minimum of 75 psi (5.2 bar)
with a maximum load of 70 lb (31.8 kg).

ATOMIZER
The AQUASONIC Atomizer utilizes patent pending advanced
technology, combining separate feeds of compressed nitrogen gas
and water to generate and uniformly distribute water droplets
throughout a protected volume.
Each atomizer is delivered pre-trimmed with the appropriate water
flow control orifice, strainer, mounting plate, and dust cap in place.
The water supply inlet is 1/2 in. NPT, and the nitrogen supply inlet
is 1 in. NPT.
The AQUASONIC Atomizer utilizes an in-line restricting orifice
plate to generate the appropriate water flow. The system design
calculation procedure found in the design section must be used to
determine the required atomizer.
Note: When ordering an AQUASONIC System, the atomizer is
based on selected orifice size.

PNEUMATIC SELECTOR VALVE
Selector valves are used when two or more hazard enclosures will
be protected with a single supply or a single main and reserve
system. Selector valves are operated pneumatically or electrically.
When electrical operation is required, a solenoid valve mounted in
the actuation line manifold on the system sends actuation line
pressure from the ANSUL AUTOMAN II-C release to the appropri-
ate selector valve. Up to eight hazard enclosures may be
protected by a single supply. Selector valve assemblies may be
used in conjunction with optional pneumatic remote actuators
where required.
An AQUASONIC selector valve assembly consists of a 3/4 in.
selector valve for water, a 1 1/2 in. selector valve for nitrogen,
brass inlet and outlet piping with union couplings, a regulator to
control actuation pressure, actuation line connections and check
valves, a poppet-style purge valve for the actuation line, an over
pressure relief valve for the actuation line, and a mounting plate.
Actuation line pressure is regulated at 50 psi (3.4 bar). Once acti-
vated, the selector valves will remain open until the actuation line
pressure is purged from the actuation line.
The solenoid is 24 volt DC 11.6 watts 0.48 amps.
