1) Ensure the left-right and up-down motors are aligned as shown in Figure 8.
®
2) Mount the Sidewinder
monitor to a securely mounted 2.0” NPT threaded pipe (additional
support may be necessary). The monitor can be mounted in any orientation, although some
orientations will reverse the directions of movement relative to the control box.
3) Ensure that all of the electrical connections have been disconnected.
4) Apply a suitable thread sealant, thread the monitor onto the pipe connection, and tighten it
securely with a strap wrench. Make sure the motor on the monitor base is facing away from the
intended center of rotation. The rotation limits are determined by the magnet locations in the
monitor body, and cannot be adjusted. (Exception: A 334° monitor can be made into a 180°
monitor by adding two magnets through an access hole).
5) Reconnect the electrical connections according to Figure 19 and Figure 20. Check all of the
electrical connections to make sure they are tight. Allow enough slack in the monitor harness to
permit travel to the limits allowed by the controller without straining the wires.

2. 81713000 Control Module
The 81713000 control module is a rugged, watertight unit, allowing it to be installed anywhere within
reach of the wiring harnesses. The cables should be routed away from any heat sources, and be
protected from sharp corners. They should be tied down securely to prevent fretting or fraying due to
vehicular vibrations. Securely mount the module to the vehicle. Connect the monitor connector to the
monitor wiring harness. Connect the control connector to the wiring harness coming from the control
box (or optional joystick). Connect the power connector to the fused power source. The control
module can be supplied by either a 12 VDC or 24 VDC power source determined by monitor voltage
requirements. See Section III.A. Monitor Controller Specifications.

3. 81122001 Control Box & 81172001 Joystick Control Box (Optional)
The control boxes can be mounted using the mounting holes provided inside of the boxes. Any
modification of the boxes themselves will void the Elkhart Brass warranty on the device. The
connector attaching the wiring harness to the control box should be inserted straight into the
mating connector on the box. Be sure to align the key with the keyway. There should be no need
to force the connectors together. The locking ring on the connector will give a positive indication
when it has locked to the connector body.
The control boxes should be mounted in a location where the wiring harness connecting to the box
will have 2 - 3 inches of straight cable before beginning a bend (see Figure 13). This will remove
stress from the connector, and prevent damage.

4. 81181001 Water Valve Kit (Optional)
The 81181001 Valve Kit is for use with 12V DC systems ONLY. To use the valve kit with a 24V
system an 81298001 Water Valve Kit (24V) should be used.
Warning:
Using the 81181001 Water Valve Kit on a 24VDC system will damage the position sensors and burn
out the motor. Elkhart Brass P/N 81298001 Water Valve Kit (24V) is the 24V replacement for the
81181001 Water Valve Kit.
Install the valve inline with the monitor. Mount the 81196000 or 81294001 control
module to the apparatus. The cables should be routed away from any heat sources, and be protected
from sharp corners. They should be tied down securely to prevent fretting or fraying due to vehicular
vibrations. Several optional cable lengths are available for the valve controller to allow it to be
mounted in a convenient location. Connect the motor power and sensor lead to the valve harness. See
Section III.B. Optional Valve Controller Specifications. Wire an inline fuse to the positive (red) lead
of the control module (the same fuse that was used for the 81713000 can be used here). Connect the
control connector to the free connector on the control harness.
The monitor and nozzle are controlled with three toggle switches at each control point. These
switches are marked “STRT-FOG”, “LEFT-RIGHT”, and “UP-DOWN”. The switches are of the
three position, momentary contact, center-off type. Simply push and hold the switch(es) to move
the monitor to the desired stream direction, or to adjust the nozzle to the desired spray pattern.
Release the switch when the proper stream position or spray pattern is achieved. To flush the
nozzle press the “FOG” switch. The nozzle will move to the wide fog position and continue on to
the flush position. Use caution when the nozzle is in the wide fog position to not accidentally
place the nozzle in the flush position. The 5000 Series and SM-10FE nozzles have a unique ball
screw drive that allows motor to “free wheel” at the end of pattern travel in either the straight
stream or wide fog positions. No slip clutch or current limiting feature is used with these nozzle
drives. To flow water with the optional 81181001 or 81298001 Water Valve kits, place the
“WATER” switch to water. This will completely open the valve. To close the valve place the
“WATER” switch to off.
2. 81172001 Joystick Control Box
With the 81172001 Joystick Control Box, the monitor, nozzle and valve are controlled with the
joystick and accompanying switches. Simply push and hold the joystick to move the monitor to
the desired stream direction. Release the switch when the proper stream position is achieved. The
nozzle spray pattern is controlled using the rocker switch on the top of the joystick. To flush the
nozzle press the “FOG” switch. The nozzle will move to the wide fog position and continue on to
the flush position. Use caution when the nozzle is in the wide fog position to not accidentally
place the nozzle in the flush position. To continuously flow water with the optional 81181001 or
81298001 Water Valve kits, place the water valve switch to “ON”. This will completely open the
valve and keep it open regardless of the lever position on the joystick. To close the valve place the
water valve switch to “JOYSTICK” and let go of the joystick lever. To flow water for short
durations leave the water valve switch in the “JOYSTICK” position and operate the valve with the
lever on the front of the joystick. The valve will open as long as the lever is held in. When it is
released, the valve will close.
B. Manual Override
In the event of power failure to one or more motors, the motor(s) may be actuated manually. To
operate a function manually, simply apply a 3/4" ratcheting type wrench (either socket type or
ratcheting box end type) to the hex fitting on the motor shaft extension. The left-right and up-down
functions can be overridden much easier if the motor wire connector is unplugged from the control
harness.
Caution:
Do not use impact drivers to operate the manual override nuts. Serious damage to the motor gearheads
will result.

VI. MAINTENANCE
A. Preventive Maintenance
The complete monitor and control system should be inspected during each apparatus check. Careful
inspection for damage to the monitor or nozzle is especially important after use of the
Monitor in emergency operations.
1. Operate each function (left-right, up-down, strt-fog) from each control point.
2. Flow water to check the nozzle pattern. If the pattern is disrupted, use the nozzle flush feature
to clear the debris. If the obstruction still remains, remove the nozzle and check for debris
lodged between the nozzle stem and body.
3. During nozzle flow test, inspect monitor swivel joints for leaks.
4. Inspect all exposed wiring for signs of damage.
Note: Although grease fittings are provided for the up-down and left-right gear cases, routine
greasing should not be necessary. If the monitor is exposed to high level of radiant heat for a
prolonged period, it may be possible for the factory grease to thin and run out of the gear cases. In
such an event, fresh grease should be applied. It is recommended that Mobilith AW2 grease be used
to lubricate the monitor gearing.
The following graphs offer the pressure losses for the monitor (and other devices) in terms of
Total Static Pressure Drop. This Total Static Pressure Drop can be found by measuring the
difference between the static inlet pressure and the static outlet pressure. The static
pressure at either of these points can be found using a simple pressure gauge. An
illustration of this method can be seen below.
In mathematical terms, the Total Static Pressure Drop is the change in Velocity Pressure
plus Friction Loss. The change in Velocity Pressure results from the change in velocity of
water caused by the change in the cross section of a waterway. Friction Loss results from
the drag and sidewall interference of the water through a device. A simple equation can be
seen below.

In the firefighting industry, the terms Total Static Pressure Drop and Friction Loss tend to be
used interchangeably. However, these are significantly different measurements. This
misconception could ultimately lead to lower than anticipated performance from equipment.
When designing a system and determining performance, Total Static Pressure Drop is
the value that should always be used. The Friction Loss curve is also supplied in order to
make a comparison with competitor products that may only supply Friction Loss curves. If
there are any further questions regarding this matter, please contact Elkhart Brass.
