PRODUCT SAFETY INFORMATION
All personnel who may be expected to operate this equipment must be thoroughly trained in its safe
Important: Before installing and operating this equipment, read this manual
thoroughly. Proper installation is essential to safe operation.
Warning: Do not attempt to disconnect or work on any electrical equipment in this
system unless power is removed or the area is known to be non-hazardous.
and proper use.
Before flowing water from this device, check that all personnel (fire service and civilian) are clear of
the stream path. Also confirm stream direction will not cause avoidable property damage.
Become thoroughly familiar with the hydraulic characteristics of this equipment, as well as the
pumping system used to supply it.
Whenever possible, this equipment should be operated from remote location to avoid exposing
personnel to dangerous fire conditions.
Always open and close valves slowly to avoid water hammer.
After each use, and on a scheduled basis, inspect equipment per instructions in the maintenance
section.
Keep fingers and hands clear of moving parts.
Disconnect power before servicing and electric valve or electric valve controller.
Any modifications to the electrical will destroy the IP-66 rating and void warranty coverage of the
enclosure and all components within.
All equipment must be installed in accordance with ATEX requirements (EN/IEC 60079-14) as
appropriate and in areas where equipment classification is suitable.

INSTALLATION INSTRUCTIONS
Monitor Installation
Warning: When installing the monitor on a raised face companion flange or wafer
type valve, it is critical that the bolts be tightened uniformly to prevent misalignment
of the monitor relative to the flange or valve. If the monitor becomes misaligned, the
base flange will fracture and fail when the bolts on the “high” side are tightened.
1. Attach companion flange to water supply pipe so that the bolt pattern will allow the monitor to be
installed with the “straight ahead/neutral” position (see Dimensional Drawing section) properly
aligned. Alignment is correct when the “straight ahead/neutral” direction is centered between
adjacent flange bolt holes.
2. Install the monitor assembly on the water supply flange so that it matches up to a 4”-150# flat
faced ANSI flange on the inlet of the monitor, with a flange gasket between the flanges. Install
motor cable junction box by aligning the two-holed bracket with the flange mounting holes on the
rear of the monitor. Secure the inlet flange with eight (8) 5/8”-11 UNC Grade 5 hex head bolts.
Torque bolts to 60-70 ft-lbs.
3. Standpipe must be structurally strong enough to withstand reaction forces of the nozzle when
discharging a straight stream at 90° of the standpipe tower. The formula for calculating nozzle
reaction is: [REACTION FORCE = 0.0505 x GPM x √ PSI]
4. The inlet pressure at the base of the monitor must be high enough to allow for pressure loss
through the monitor. To accomplish this, use the pressure loss for GPM flowing and add to nozzle
pressure. See Monitor Hydraulic Data section for pressure loss chart.

Monitor Cable Routing
Figure 2: Monitor Cable Routing
1. Route cables as shown in Figure 2 below, so they will follow the vertical and horizontal movement
of the monitor. Make sure that the wire loops for horizontal and vertical movement is great
enough to eliminate any stretching of cables throughout the full movement of the monitor.
2. Wire tie cables together as shown in Figure 2 below. This will eliminate the cables from tangling.
3. Wire tie the nozzle cable to pressure gauge, allowing a long enough loop so vertical movement of
monitor will go to the full down position without stretching the cable.

Monitor Safety Boot and Clamp Installation
Figure 3a: Monitor Motor Boots
Figure 3b: Nozzle Motor Boots
All Motor Cable Connections are provided with clamped safety boots. These boots must not be
removed when monitor motor control panel is energized and area is hazardous.
1. Install corrugated black plastic boot on cable connector as shown so split lines up with cable.
2. Install clamp around top of boot and connector swivel.
3. Tighten clamp down around swivel and boot.

One Monitor Control
MAINTENANCE
Warning: Do not attempt to disconnect or work on any electrical equipment in this
system unless power is removed or the area is known to be non-hazardous.
This operator control panel has one set of switches and pilot lights to operate one monitor.
Monitor Functions – UP, DOWN, LEFT, & RIGHT are operated with spring return joysticks. This is
accomplished by using the proper selector/pushbutton joystick to move the monitor the direction
desired. When joystick is released, it will return to original (off) position, and monitor movement
will stop.
Monitor Manual Control
Vertical Manual Override – Push hand wheel inward to engage override. While holding the
hand wheel in, rotating it clockwise will raise the nozzle, and rotating it counter-clockwise will
lower the nozzle.
Horizontal Manual Override – Push hand wheel inward to engage override. While holding hand
wheel in, rotating it clockwise will move the monitor right, and rotating it counter-clockwise will
move the monitor left.
When monitor operation is completed, move vertical movement to full down position to allow water to
drain from nozzle. When water is drained from nozzle, move monitor to park position.
Monthly Inspection & Maintenance
Cycle all monitor functions (LEFT, RIGHT, UP, DOWN) to insure the complete system is fully
functional.
Six-Month Inspection & Maintenance
Grease monitor ball races through grease fittings located at each swivel joint. Recommended
grease for Industrial Spit-Fire® monitors is MOBILITH SHC – 100, High Performance Synthetic
Grease. Temperature range: -40°F (-26°C) to 400°F (250°C) or equal. Greasing procedures are
as follows:
o Apply approx. 5-7 pumps of grease in the lower grease fitting, and 2-3 pumps in the
upper grease fitting
Check motor control cables for water and connectors for damage.
Check motor cables for binding through full movement of monitor.
Check all painted surfaces for chips or scratches, and repaint as required.
Visually check all electrical equipment.
