Warning/Caution Notations
WARNING:
Personal injury or loss of life
may occur if you do not follow
the procedures as specified.
CAUTION:
Equipment damage, or loss of
data may occur if you do not
follow the procedures as
specified.
Required Tools
•Strap wrench
•Spanner wrench
•WD-40 (or similar)
•Silicone RTV sealant
•SINX 16, 17, or 18 for respective size
•Torque wrench with 3/8" drive
Figure 1.
Prerequisites
Verify that there is a sufficient quantity of HFC227ea
in inventory to complete the entire recharge of each
cylinder.
Figure 2.
WARNING:
Although the pressure gauge may register a
“Zero” reading, caution must be used at all
times since residual pressure may still be
present.
CAUTION:
Before beginning this procedure, make sure
the Anti-Recoil Device is installed on the
cylinder.
Disassembling the Valve
1. Energize the solenoid or depress a Local
Manual Control (CPY-LMC) to ensure there is
no pressure in the cylinder. It is normal to notice
a slight pressure release. At this point, THERE
IS NO PRESSURE IN THE CYLINDER.

2. Remove the brass valve from the cylinder by
unscrewing from the cylinder neck. Remove the
valve and the siphon tube assembly and set
aside.
CAUTION:
Do NOT use a pipe wrench as this will
scratch the valve. Use a strap wrench or
attach a piece of pipe to the outlet for
leverage.
Figure 4.
3. Remove the siphon tube assembly from the
valve.
Figure 5.
4. Place the valve assembly into a bench-mounted
vice with rubber inserts or heavy canvas over
the teeth of the vise. (Do not scratch the valve
surface.)
5. Remove the top plug adapter using a spanner
wrench.
Figure 6.
NOTE: 1. The top plug adapter unscrews with
a right-hand thread.
2. There is a spring under the top plug
adapter that will push up the top
plug once the threads are
disengaged.
Figure 7.
•Remove the O-ring from the top plug
adapter.
Figure 8.
6. Remove the piston from the inside of the valve
body.
Figure 9.
•Clean the interior surface of the valve body
utilizing a product like WD-40, removing all
of the residual O-ring lube.

Reassembling the Valve
1. Reassemble the piston.

and seat.
b. Apply a small amount of Parker-o-Lube
grease to O-rings (CPY-G).

d. Install a new O-ring on the top plug
adapter.
Figure 18.
a. Apply a small amount of Silicone RTV to
both locations shown below. Install a new
valve seat, and tighten the retaining clamp
using SINX 16, 17, 18 (for respective size).
Use a torque wrench with a 3/8" drive (Set
to proper torque setting).

c. Reinstall the valve body to the cylinder (if
needed). Tighten until a metal-to-metal fit is
achieved.
d. Assemble the piston to the valve body.
Make sure to install the piston with the
rubber seat leading into the bottom of the
valve body.

SINORIX Cylinder Filling
Pump Setup
1. Connect the pump to the agent source
(example of valve for the Bulk 1200 lb cylinders
from DuPont™below. The blue knob opens the
cylinder to flow vapor only; the red knob opens
the cylinder to flow liquid agent.)
NOTE: Some bulk cylinders and valve knobs
may have been painted, but the
position of the knobs shown in this
picture is the correct orientation.
Figure 23.
2. Connect the liquid line (suction hose) from the
pump to the bulk storage cylinder.
a. Open the Liquid Supply Valve (red knob).
b. Before connecting the manifold to the
cylinder to be filled, purge all air out of the
pump and hoses by opening the Agent
Valve on the fill manifold and the Nitrogen
Valve (without the nitrogen source
connected.) until liquid begins to flow.
Then, close the Nitrogen Valve, and close
the Agent valve.
c. Connect the nitrogen source hose to the
manifold.
Cylinder Setup and Filling
1. Install the filling adapter to the discharge port of
the cylinder.
Figure 24.
a. Before placing the cylinder, reset the scale
to 0.
b. Record the Empty Cylinder Weight.
c. Connect the Fill Manifold to the Fill Adapter.
Figure 25.
d. Press the Tare button on the digital scale.
This will set the display to 0without
resetting the Gross Weight.
•If not using a digital scale, record the
weight of the cylinder with the Fill
Manifold connected.
e. Verify the amount of agent to be placed in
the cylinder.
•If not using a digital scale, add the
previous weight from (2, d) to the
amount of agent required to determine
the final fill weight.
f. Open the Agent Valve and agent should
begin to flow into the cylinder.
g. Turn on pump (Pump equipment varies,
please refer to your specific pump’s
instructions)
h. Monitor the scale until the cylinder fill
weight reaches the required weight of
agent.
i. Close the Agent Valve and immediately
turn off pump.
j. Verify agent fill weight is correct.
k. Close Liquid Supply Valve on bulk agent
supply cylinder.
l. Open valve on nitrogen source and set the
regulator secondary pressure to approx
450 psi.
m. Open the Nitrogen Valve on the Filling
Manifold until the pressure gauge on the
cylinder reaches 360 psi, then close the
Nitrogen Valve.

n. Disconnect the Nitrogen Supply Hose from
the Filling Manifold. The Cylinder Valve
should reseat itself. To verify the valve has
closed, slowly open the Nitrogen Valve on
the Filling Manifold; residual pressure will
begin to decrease.
If you begin to see liquid flowing out of the
Filling Manifold, close the Nitrogen Valve.
This indicates the valve did not reseat
properly. If this occurs:
i. Connect an adapter to the discharge
port on the solenoid.
ii. With the Filling Manifold still
connected to the Fill Adapter on the
cylinder, energize the solenoid with
the correct voltage to open the
solenoid.
iii. Apply 450 psi of Nitrogen for 10
seconds.
iv. Turn off the power to the solenoid.
v. Repeat step “m”.
vi. Close the valve on the nitrogen
source.
o. After it has been verified that the valve is
properly seated, remove the Filling Manifold
and Refill Adapter, then immediately install
the Anti Recoil Plug.
p. Monitor the pressure for 24 hours. Nitrogen
will be absorbed into the liquid HFC227ea,
reducing cylinder pressure. This absorption
can be accelerated by agitating the
cylinder, and may require multiple additions
of Nitrogen to assure that the HFC227ea
has reached its full saturation point.
q. If pressure is less than 360 psi, reinstall the
Refill Adapter and Filling Manifold.
r. Repeat steps “m”, “n” and “o” to adjust the
pressure to 360 psi.
NOTE: Do not return the cylinder into
service until the pressure has
remained at 360 psi, (at 70°F), for
a minimum of 6 hours.
s. Perform a leak check.
The installation is now complete.
