Assembly of the Fire Extinguishing System
(continued)
The following assembly instructions for the fire
extinguishing system are to be used with the layout
and description shown on page 32.
- Install the mounting bracket (6) near the in-feed auger
at a minimum height of 20 in. (500 mm) with the stud
anchors (5) for wall mount.
- Install the plastic container (7) to the mounting
bracket (6) with the clamping bands (8), the threaded
rods (4), washers (2) and the hex nuts (3).
- Attach the 90° street elbow (10) to the duct (9)
- Assemble the strainer (11), connector (12),
thermostatic valve (13), reducer (14), union (15),
gasket (16) and the 90° street elbow (17) and
connect the assembly to the weld on nipple (18).
Note:
The Weld on nipple (18) is pre-installed at the
metering container. The Weld on nipple (18) needs
