I. PRODUCT SAFETY

Important:

Before installing and operating this equipment, read & study this manual
thoroughly. Proper installation is essential to safe operation. In addition, the
following points should be adhered to in order to ensure the safety of equipment
and personnel:

1. All personnel who may be expected to use this equipment must be
thoroughly trained in its safe and proper use.

2. Before flowing water from this device, check that all personnel (fire
service and civilian) are out of the stream path. Also, check to make sure
stream direction will not cause avoidable property damage.

3. Become thoroughly familiar with the hydraulic characteristics of this
equipment, and the pumping system used to supply it. To produce effective
fire streams, operating personnel must be properly trained.

4. Open water valve supplying this equipment slowly
slowly, thus preventing possible water hammer occurrence.

5. After each use, and on a scheduled basis, inspect equipment per
instructions in Maintenance & Inspection on page 4.

, so that the piping fills

Warning: The piping must be able to withstand a horizontal reaction force of at least

850 lbs at the height of the vertical swivel joint center and from any angle of rotation that the
monitor is capable of turning. Serious injury to personnel and equipment can result from improper
installation.

II. INSTALLATION INSTRUCTIONS

1. NPT Base

Apply an appropriate thread sealant to the NPT nipple. Thread the monitor base onto
the nipple and tighten with pipe wrench.

2. Flat Faced Flange

a) Attach an ANSI pattern companion flange to the water supply pipe.
b) Seal the flange joint with a full face gasket or suitable flange sealant. Most

wafer type butterfly valves have seats that serve as flange gaskets, and
separate gaskets or sealant is not required.

c) Attach the monitor inlet flange to the companion flange on the water supply

pipe with grade 5 carbon steel or stainless steel bolts with nuts. See Table 1

for quantity and size of bolts. If an Elkhart Brass Model 84 butterfly valve is
installed between the monitor and the companion flange, the bolt length should
be 4-½”.

d) Apply Loctite® #242 to the bolt threads, then thread on the nuts, and torque

the flange bolts to 60-70 ft-lbs for ⅝” and 110-120 ft-lbs for ¾” uniformly in
increments of approximately 20 ft-lbs.

Note: Elkhart Brass recommends using part number 81315001 Companion Flange
Kit for a 3” 150# flat face flange and part number 81317001 Companion Flange Kit for
a 4” 150# flat face flange.

Base # Bolts Size of Bolts Minimum Length of Bolts

2-½” 150# ANSI Flange 4 ⅝”-11 UNC 2-½”
3” 150# ANSI Flange 4 ⅝”-11 UNC 2-½”
4” 150# ANSI Flange 8 ⅝”-11 UNC 2-½”
6” 150# ANSI Flange 8 ¾”-10 UNC 3”
2-½” 300# ANSI Flange 8 ¾”-10 UNC 3”
3” 300# ANSI Flange 8 ¾”-10 UNC 3”
4” 300# ANSI Flange 8 ¾”-10 UNC 3”

Table 1

Warning: When installing monitor on a raised face companion flange or butterfly

valve, it is critical that bolts be tightened uniformly to prevent cocking of the monitor relative to the
flange or valve. If the monitor becomes cocked, (see Figure 1) the monitor cast flange base will
fracture and fail when the bolts on the "high" side are tightened.
