Product Warnings, Cautions and Notices
Charge the unit slowly. Rapid charging may cause a pressure surge that has the potential to cause an injury,
or damage the monitor.
Do not stow or deploy the monitor while flowing. Pressing the Stow or Deploy buttons causes the nozzle to
move automatically and the water stream may cause damage to equipment or injury to personnel.
Aim the unit in a safe direction before pumping water through it, e.g., away from power lines.
Do not use the electric controls when the manual override cranks are being used or are in position for use.
Make the connection of the vehicle and auxiliary battery the final step.
Do not exceed the maximum pressure or flow ratings of the monitor. Exceeding these ratings may lead to an
injury or may cause damage to the monitor.
Do not install shutos on the outlet of the monitor. Shutos increase the potential for pressure surges
due to water hammer, which have the potential to cause an injury or damage the monitor.

Disconnect power and disable flow before maintenance.
Keep all personnel out of the Danger Zone, in front of the outlet of the monitor when the water source is
attached. Dangerous flow velocities can cause serious injury.
Not designed for explosive environments.
Use only for firefighting by trained operators.
Ensure the thread on the nozzle swivel matches the thread on the monitor outlet. Do not over-tighten the
nozzle onto the unit.
Insucient structural support at the inlet flange can lead to failure, which has potential to cause an injury.
Do not use monitor or nozzle as a forcible entry tool.
Ensure that the monitor is returned to the Stow position after use.
During freezing conditions, the monitor must be drained to prevent damage.
The monitor, nozzle, control box, tether controller and field adjustable stops are made for optimal
performance. Do not alter in any manner.
The monitor was designed for use with Akron nozzles. Use of any other nozzles could aect the speed
or operation of the unit and should be tested before being put into service.
Replace the identification tags if they should become worn or damaged.
The monitor uses current limiting for both the monitor and nozzle. Use only appropriate
Akron Brass Company nozzles.
Designed for use in freshwater applications. If used with salt water, flush with freshwater.
For use with water or standard firefighting foams only. After use with foam, flush with freshwater.
Not recommended to mount onto a raised flange. This may cause damage to the monitor’s flange
when tightening bolts.
Use a nozzle of the same material as the monitor to eliminate the eects of galvanic corrosion.

Mechanical Monitor Attachment
The monitor is to be mounted on a waterway which is capable of withstanding the pressure applied to the monitor as well as the
reaction force and resulting bending moment of the nozzle (1700 lbs at 250 PSI and 2000 GPM).
Insucient structural support at the inlet flange can lead to failure, which has potential to cause an injury.
Use 5/8" bolts and nuts of grade five minimum. Use suitable washers with a minimum of six thread engagements. Use a ring gasket
conforming to ASME 16.21. The control box is considered the front of the monitor. Use Figure 1 to position the monitor to function
within the desired operating window.

Bolt Tightening Procedure
Start the tightening procedure by lubricating the nuts and bolts. Hand tighten the nuts until they are snug against the flange.

The final torque of the bolts should be 85–90 ft-lbs. Following the correct sequential order, tighten the bolts to 30% of the final
torque. Repeat the tightening sequence to 60% of the final torque. Repeat a third time to 100% of the final torque. Finally, repeat the
sequence at the final torque.
Not recommended to mount onto a raised face flange. This may cause damage to the monitor’s flange when
tightening bolts.

Rotational Stops
177-1/2°
45° LEFT
FR
The StreamMaster II™ has 355º of total rotation. Stops can be inserted to limit travel to the left or to the right according to figure 3.
Factory default stops are set at 90º to the right and left. The permanent stop must not be removed. The stops and plugs have a ½”
hex head. If a hole does not have a stop, it should have a plug.
Operating the monitor without the permanent travel limit stops in place could cause damage to the
monitor and could potentially injure the operator.
