IN-LINE BURST DISC ASSEMBLY (MANIFOLDED
SYSTEMS ONLY)
The in-line burst disc assembly is required to eliminate the
siphoning of the agent up the pipe during extreme temperature
variations. In addition to eliminating the siphoning effect, the
common in-line burst disc assembly eliminates the possibility
of one or more individual discs located in the tank adaptor from
failing to burst. The assembly consists of a stainless steel body
which houses the burst disc. When utilizing this assembly in a
manifolded system, it is necessary to modify (remove) the burst
disc located in all of the R-102 tank adaptors in the system. The
in-line burst disc assembly is to be mounted as close to the tank
outlet as possible. After system discharge, the assembly must
be disassembled and a new burst disc installed.

1/4 IN. CHECK VALVE
The 1/4 in. check valve (Part No. 25627) blocks the flow of
actuation gas from the actuator that was actuated to the actu-
ator(s) that was not actuated. This prevents actuation gas from
escaping from an open actuator which may have had the car-
tridge removed.

NOZZLE AIMING DEVICE
The Nozzle Aiming Device (Part No. 439877) is available to
properly aim each nozzle to the correct aiming point. The device
clamps to the nozzle and emits a small laser light that reflects on
the surface that it is aiming at. The nozzle can then be rotated to
point at a predetermined aiming point and then tightened to hold
that angle. The aiming device adaptor attaches to the nozzle.
The shipping assembly consists of the aiming device and the
adaptor.

STAINLESS STEEL BRAIDED ACTUATION HOSE
The Stainless Steel Actuation Hose is used to connect the actu-
ation line compression tees between each pneumatic actuator.
The hose has the same thread, 7/16-20, as the fittings. The
actuation hose allows flexibility between the AUTOMAN and
each regulated actuator.
