AFTER SYSTEM RELEASE
After a discharge, return the system to operating mode as soon as possible. Ensure that the
Argonite cylinder pressure gauge(s) on the refilled cylinder valve(s) reads 2900 PSI
(200 bar) at 70°F (21.1°C).

Cylinder Replacement
Safety is a prime concern! Never assume that a cylinder is empty; treat all
cylinders as if they are fully charged. The Kidde Fire Systems cylinder valve is
capable of producing high discharge thrusts out of the valve outlet if not handled
properly. Remember that pressurized cylinders are extremely hazardous. Always
fit the cylinder valve with a protective cap before removing the cylinder(s) from
the rack and/or moving the cylinder(s). Failure to do so can result in serious
bodily injury and possibly death, as well as property damage.
When an Argonite cylinder has been operated or the remaining pressure is less than
2750 PSI (190 bar), it should be refilled immediately to the normal operating pressure at
70°F (21.1°C).
Before removing the cylinder from its bracket assembly, the following steps should
be followed:
1. Disable the solenoid release circuit on the control panel.
2. Remove the coil from the high pressure solenoid valve unit, remove nut/screw and
pull out the coil.
3. Disconnect the pilot hose (19 mm hex) from the cylinder valve connection.
4. Carefully loosen the 36 mm swivel nut on the gauge unit to relieve pressure out the
vent hole.
5. When the pressure indicated on the pressure gauge has fallen to zero (0), disconnect
the gauge unit from the cylinder valve.
6. Disconnect the pilot hoses and discharge hoses from the cylinder valve outlets.
7. Fit the protective cap on the cylinder.
8. Remove the cylinder bracket.
9. Roll the cylinder out from the wall bracket, free of the manifold.
10. Place the cylinder on the cylinder carrier and tighten the holding strap.
11. Move the cylinder to a truck and secure.
12. Repeat steps 1 to 13 until all cylinders have been placed on the truck.
13. When all cylinders are out of the room and secured on the truck, drive to nearest
refilling station or contact Kidde Fire Systems.
An Argonite cylinder can weigh more than 300 lb. Always take precautions to
prevent personnel injuries. All dismantled parts are to be treated with great
care in order to avoid damage. Cylinders should never be dragged, rolled or
allowed to strike any object.

Re-Installation
Follow Steps 1 to 13 above in reverse order.
Discharge hoses must be connected into the system piping before being attached
to the cylinder valve outlet to prevent injury in the event of discharge.
