4-7.2 Manifold Safety Device
Wherever there are closed sections of pipe, install a manifold safety device. This device pre-
vents any unlikely overpressure within the pipe.
Note: The manifold safety device may be vented to atmosphere or connected to the down-
stream pipe work (after any selector valves if applicable) to prevent accidental expo-
sure to the Agent in quantities that may exceed exposure limits within the cylinder
storage room.
1. Locate the venting for the manifold safety device in an area where the Agent can be safely
discharged without exposing personnel.
2. Ensure that the maximum allowable working pressure of the closed section of pipe is equal
to or greater than the maximum operating pressure of the manifold safety device, which is
90-96.5 bar for part number 38-400006-002.
3. The Safety Outlet (Figure 4-10) must be installed upstream of any selector or stop valve
(if applicable). Connection to the piping is made with a 3/4-inch NPT fitting. Attach the
wrench to the body of the safety outlet. Do not tighten or loosen the retaining nut contain-
ing the safety disc.

4-7.3 Install Discharge Hoses to Manifold Check Valves
After installing the manifold, install the discharge hoses to the manifold check valves.
4-7.4 Securing Single-Row Cylinders
Follow this procedure to secure the cylinders in a single row:
Note: The installation of the manifold and the pipe work within the cylinder storage area/room
must be completed before cylinders are moved into the cylinder storage area/room.
1. Use M12 expansion bolts with washer or similar to secure the channel iron/Unistrut supplied
to a wall or solid structure. On steel structures, The channel iron/Unistrut could be fixed by
welding.
2. Tighten bolts in accordance with the manufacturer’s recommendation for the selected fixing
and the strength of the wall.
3. Install all sections of channel iron/Unistrut horizontally and at the same height from the
floor.
4. For single row, secure the cylinder using the single row bracket, P/N 01-8131-1000 for
140 L cylinders and P/N 01-8131-0000 for 80 L cylinders.
