Section 1 General Information
1 GENERAL INFORMATION
is manual describes the procedure for recharging/refilling Janus Fire Systems® Sv Series, Mv Series, and
Lv Series cylinder assemblies with Novec 1230 Fire Protection Fluid.
1.1 Listings and Approvals
To maintain FM Approval for Janus Fire Systems® Fire Suppression Systems, cylinder recharge must be
performed at a Janus Fire Systems® recognized facility.
1.2 Extinguishing Agent
Novec 1230 fluid (FK-5-1-12) is formed from the elements carbon, fluorine and oxygen (CF3CF2C(O)
CF(CF3)2 - dodecafluoro-2-methylpentan-3-one). e primary extinguishing mechanism of Novec 1230
fluid is heat absorption, with a secondary chemical contribution from the thermal decomposition of Novec
1230 fluid in the flame. Novec 1230 fluid leaves no residue and is safe for use in occupied spaces.
Novec 1230 fluid is a highly fluorinated ketone containing no chlorine or bromine. As a result, the Ozone
Depletion Potential (ODP) for Novec 1230 fluid is zero, meaning it has no effect on stratospheric ozone.
Novec 1230 fluid has an atmospheric lifetime of 0.014 years. It has a Global Warning Potential of 1.
Janus Fire Systems® Engineered Fire Suppression Systems store Novec 1230 fluid as a liquid in steel
cylinders. e liquid Novec 1230 fluid is superpressurized with nitrogen to 360 psig (24.8 bar) at 70°F
(21.1°C). When discharged, Novec 1230 fluid is atomized at the discharge nozzles and becomes thoroughly
mixed with the air throughout the protected area reaching a predetermined design concentration.
NOTE: Bulk Novec 1230 fluid must be purchased from Janus Fire Systems and must bear the UL and FM
marks on the container.
1.3 Safety Considerations
All safety guidelines contained in this manual must be read and understood before filling any Janus Fire
Systems® cylinder. All applicable guidelines shall be followed before, during, and after the fill procedure
including any additional local standards or regulations determined by the authority having jurisdiction
(AHJ). Where the guidelines in this manual and local guidelines or regulations conflict, the most stringent
requirement should be followed.
ose individuals responsible for the filling of a Janus Fire Systems® cylinder assembly with Novec 1230
Fire Protection Fluid must be trained.

Document # DOC181
Issued: May 31, 2011
Revised: June 23, 2020
Section 1 General Information
At a minimum, Janus Fire Systems recommends the following safety equipment be worn at all times during
the fill procedure:
• Work boots with protective toe guards
• Safety glasses or goggles
• Gloves to prevent injury of the hands or fingers.
• Properly fitting clothing.
• Properly fitting ear plugs or other hearing protection.
Cylinder filling must be performed in a well ventilated area.
When Novec 1230 uid is exposed to temperatures greater than 1300°F (700°C), the potentially hazardous
byproduct hydrogen uoride (HF) will be formed during agent decomposition. Heat sources such as space
heaters, torches, welding equipment, or lit cigarettes are capable of reaching temperatures that initiate agent
decomposition. All such potential heat sources must be cleared from the work area before beginning ll process.
Smoking in the vicinity of the lling equipment or agent storage containers shall be prohibited.
e Material Safety Data Sheet (MSDS) on Novec 1230 Fire Protection Fluid can be found in Appendix
A of this manual and shall be read and understood before working with the agent.
Accidental discharge of an unsecured cylinder may result in property damage, injury, or death from
violent cylinder movement. Cylinder assemblies must be restrained at all times during the ll procedure. Anti-
recoil safety plugs and devices must be in place at all times the cylinder assembly is not connected to agent ll
lines or discharge piping. Do not transport the cylinder unless the anti-recoil safety device is in place. Handle the
cylinder assembly with care even when the safety device in is place.
e technical manual supplied with the fill station or pump must be read and understood prior to filling
cylinder assemblies. All procedures contained in the aforementioned manual must be followed and all
warnings or safety guidelines noted. Refer also to 3M™ Novec™ 1230 Fire Protection Fluid Storage and
Handling document 60-5002-0131-8.
The lling station or pump designated for use with Novec 1230 uid shall not be used with any other agents. Each
agent stored at a ll facility must have its own separate lling station or pump. Use of multiple agents with a single
lling station may result in contamination of agent and dilute its e󰀨ectiveness as a means of suppression.

Section 2 Cylinder Assembly
2 CYLINDER ASSEMBLY
e cylinder assembly consists of the cylinder, dip tube, and cylinder valve.
2.1 Cylinder
e Novec 1230 fluid is stored as a liquid inside a welded steel cylinder. e cylinders are superpressurized
with dry nitrogen to a pressure of 360 psig (24.8 bar) at 70°F (21°C). Every cylinder has a minimum fill
density of 35 lb/ft3(561 kg/m3) and a maximum fill density of 70 lb/ft3(1121 kg/m3). e capacity of a
cylinder varies according to the design requirements and the Series designation (See Table 2.1.1 for a list of
available capacities).
Standard domestic cylinders
are manufactured according
to the requirements of
the U.S. Department of
Transportation (USDOT)
andTransport Canada1(TC)
for compressed gas and are
fitted with an identification
label indicating the fill
quantity of Novec 1230
fluid. Each cylinder has
internal neck threads to
allow for connection to the
cylinder valve.
2.1.1 Rupture Disc
A frangible rupture disc is fitted to the Lv Series cylinder body. It functions as an emergency relief device in
the event of excessive internal pressure within the cylinder. Its rupture point is between 850 psi (58.6 bar)
and 1000 psi (68.9 bar).
is feature is not found on the Sv Series or Mv Series cylinder. Instead, a rupture disc is located on the side
of Sv Series and Mv Series cylinder valve as detailed in sections 2.3.1 and 2.3.2.
2.1.2 Liquid Level Indicator
e liquid level indicator consists of a sealed non-magnetic tube containing an external measurement tape
fitted with a magnet. A second magnet with an opposing polarity is installed on the outside of the tube
and is exposed to the liquid Novec 1230 fluid. As the tape is extracted from the tube, it will engage with
the second magnet creating a noticeable change in tension. e measure on the tape when this change in
tension occurs indicates the current liquid level inside the cylinder and can then be compared to a chart
located in Appendix B of this manual to determine the current fill weight of the cylinder.
e liquid level indicator assembly is threaded into an outlet on the head (top) of the Mv Series and Lv
Series cylinders.
is feature is not found on the Sv Series cylinder.

e pump connection port is a 1/4 in (8 mm) male quick-connect fitting attached directly to the manual
agent fill valve and serves as the connection point for the agent fill station. e male quick-connect fitting
of the pump connection port contains an internal check valve that prevents agent from flowing through the
fitting unless it is connected to the fill station.
3.2.2 Cylinder Connection Port
e cylinder connection port is located opposite of the pump connection port and is a 1/4 in (8 mm) female
quick-connect fitting that serves as the connection point for the 1/4 in (8 mm) male quick-connect fitting
on the fill adapter (refer to section 3.1). e female quick-connect fitting of the cylinder connection port
contains an internal check valve that prevents agent from flowing through the fitting unless it is connected
to the fill adapter.
3.2.3 Gauge Connection Port
e gauge connection port is a 1/4 in (8 mm) male quick-connect fitting that serves as the connection point
for the fill pressure gauge. It is located on the same side of the cylinder fill assembly as the handle for the
manual agent fill valve. When connected to the cylinder valve, the cylinder fill assembly must be oriented
so that the gauge connection port is perpendicular to the ground and pointing upwards. e male quick-
connect fitting of the gauge connection port contains an internal check valve that prevents agent from
flowing through the fitting unless the fill pressure gauge has been installed to it.

3.2.4 Nitrogen Pressurization Port
e nitrogen pressurization port is located opposite of the gauge connection port and is a 1/4 in (8 mm) male
quick-connect fitting that serves as the connection point for the nitrogen supply used to superpressurize
the cylinder assembly. When connected to the cylinder valve, the cylinder fill assembly must be oriented
so that the nitrogen pressurization port is perpendicular to the ground and pointing downwards. e male
quick-connect fitting of the gauge connection port contains an internal check valve that prevents agent
from flowing through the fitting unless it is connected to the nitrogen supply.
3.3 Nitrogen Regulator/Hose Assembly
P/N 99516 (See Figure 3.3)
e nitrogen regulator/hose assembly is comprised
of a self-relieving pressure regulator, a safety
relief valve, and two manually actuated ball valves
connected to hose lines ending in female quick-
connect fittings. e regulator-hose assembly serves
as a connection point between the nitrogen supply
and both the nitrogen pressurization port of the
cylinder fill assembly and the inlet port of the valve
closing adapter. e regulator has a CGA fitting for
attaching to the nitrogen supply.
3.3.1 Valve Closing Line
e valve closing line refers to the flex hose and manually actuated ball valve in line with the pressure
regulator. e valve closing line ends with a 1/4 in (8 mm) female quick-connect fitting that attaches to
the 1/4 in (8 mm) male quick-connect fitting located on the inlet of the valve closing adapter (see Section
3.4). It is used to close the cylinder valve by applying pressure to the top of the cylinder valve piston. e
valve closing line quick-connect fitting contains an internal check valve that prevents nitrogen from flowing
through the fitting unless it is connected to the valve closing adapter.
3.3.2 Cylinder Pressurization Line
e cylinder pressurization line refers to the flex hose and manually actuated ball valve branching off from
the valve closing line and is perpendicular to the outlet of the pressure regulator. e cylinder pressurization
line ends with a 1/4 in (8 mm) female quick-connect fitting that attaches to the nitrogen pressurization
port of the cylinder fill assembly. It is used to supply the nitrogen required to superpressurize the cylinder
assembly following agent fill. e cylinder pressurization line quick-connect fitting contains an internal
check valve that prevents the nitrogen from flowing through the fitting unless it is connect to the nitrogen
pressurization port.

3.4 Valve Closing Adapter
P/N 17292 (See Figure 3.4)
e valve closing adapter is threaded onto the valve actuation connection of
the cylinder valve and receives pressure from the nitrogen supply at the end of
the filling procedure to close the cylinder valve. A 1/4 inch (8 mm) male quick-
connect fitting (P/N 99499) is installed in the 1/4 inch (8 mm) FNPT inlet
port of the valve closing adapter and is utilized to facilitate connection to the
valve closing line of the nitrogen regulator-hose assembly.
