Monitor Installation
An Akron Brass, model 3578, 2000 GPM rated monitor shall be provided at the end of the waterway. The
monitor is an all electric single waterway monitor constructed of lightweight Pyrolite with a 4", 150 pound

enclosed motors and gears with manual overrides for both horizontal and vertical rotation. The manual
override shall have captive cranks, one for horizontal and one for vertical rotation, and may be used
simultaneously.
Three (3) toggle switches shall be located at the turntable aerial control stand and at the platform control
cosole. The switches will control the raise/lower, stream/shape, and left/right functions of the monitor. The
controls at the aerial control stand will override the controls at the tip of the aerial.
An Akron Brass model 5178 electrically controlled combination solid stream and fog nozzle shall be
provided at the end of the monitor. The nozzle shall be constructed of Pyrolite, with a 2" orifice solid bore,
and a fog flow of 1500 GPM at 80 PSI. The nozzle shall have a 12 volt electric motor, a 3.5" NH inlet, and
built-in stream shaper.
Butterfly Valve
One (1) 4" handwheel operated butterfly valve shall be installed between the end of the waterway and the
monitor. The butterfly valve shall direct water flow from the waterway to the 2-1/2" pre-connect discharge at
the rear of the platform basket. A 2-1/2" quarter turn ball valve shall be installed ahead of the 2-1/2" pre-
connect discharge. The 2-1/2" pre-connect with 90 degree swiveling discharge shall have a NH male thread.

One (1) 1-1/2" quarter turn drain valve shall be installed at the low point of the waterway plumbing system.
SINGLE DISPLAY AERIAL WATERWAY FLOW METER
One (1) Single Display Flowminder shall be provided. The digital pressure gauge includes large super bright
