OPERATING INSTRUCTIONS FOR ELECTRIC LADDER PIPE
A. UPPER AND LOWER CONTROL OPERATION
The upper and lower control boxes are used to control the monitor and nozzle. To change the nozzle pat-
tern toward the "straight stream" or "fog" position press the proper toggle switch toward "STRAIGHT" or
"FOG" respectively. To change the vertical monitor position upward or downward press the proper toggle
switch toward "RAISE" or "LOWER" respectively.
THE LOWER CONTROL BOX FUNCTIONS WILL OVERRIDE THE UPPER CONTROL BOX FUNCTIONS IN
COMPLIANCE WITH THE REQUIREMENTS OF THE NFPA STANDARD. NOTE: THE LOWER CONTROL
AND UPPER CONTROL WIRES MUST BE ATTACHED TO THE CORRECT TERMINALS FOR THE LOWER
CONTROL TO OVERRIDE THE UPPER CONTROL. NONE OF THE FUNCTIONS CAN BE CONTROLLED
FROM THE UPPER CONTROL BOX WHEN ANY OF THE SWITCHES ON THE LOWER CONTROL BOX ARE
ACTIVATED.
B. ELEVATION STOPS
The elevation stop sets the upper limit of the elevation. The monitor is shipped with the elevation stop at
90° above horizontal and can travel 45˚ below horizontal. The vertical position of 45°, 60° and 75° above
horizontal can be achieved by switching the stop to the desired locations located on the elevation gear
(Figure 1).
C. MANUAL OVERRIDE CONTROL
THE MANUAL OVERRIDE CONTROL IS TO BE USED WHEN THE POWER TO THE MONITOR IS OFF. One
override crank is attached, for the vertical control. It is
the overrides. To use the manual override pull the key pin which holds the override crank in place and insert
the hex head end of the override crank in the hexagon shaped hole beside the crank storage bracket. Then
rotate or spin the override crank either clockwise or counterclockwise to aim the monitor in the desired direc-
tion.
WHEN THE OVERRIDE CRANKS ARE NO LONGER IN USE PUT THEM BACK IN THE STORAGE POSI-
TION. DO NOT USE THE ELECTRIC CONTROLS WHEN THE OVERRIDE CRANKS ARE BEING USED OR
ARE IN POSITION FOR USE.
