PERATION
A. Stream Adjustment
ELECTRIC;
The controls for the monitor can be used to change the nozzle’s stream pattern from straight
stream to wide fog. The 12 (24) VDC electric actuator uses a ball screw mechanism that free
spins at each end of its stroke preventing the actuator motor from experiencing a stall condition
at the ends of its stroke. The nozzle may be operated in any position from straight stream to
wide fog. Motor power required is 11-14 (22-27) VDC. Motor current draw is approximately 0.5
(0.25) Amps.
MANUAL;
The electric actuator has a ¾ inch hex nut that can be used to change the stream pattern in
the event that power is lost. Disconnecting the power lead to the nozzle will make it easier to
turn the manual override nut. NEVER use anything but a hand wrench to operate the manual
override. Using powered tools will damage the nozzle actuator and void the warranty.
