Elkhart Brass ELKHART 6000-700E MONITOR NOZZLE - Manual (Page 4)

OPERATION:
ELECTRIC;
The controls for the monitor can be used to change the nozzle’s stream pattern from straight stream to wide fog.
The 12V DC 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. Refer to the chart for nozzle flow vs. pressure found on page 5
for nozzle performance.
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.
FLUSH;
Press down on the finger pad of the locking lever and while holding it down grasp the nozzle’s electric actuator
assembly and rotate the front portion of the nozzle until the locking lever is past the 200 gpm as far as it will go.
Flow water to flush out debris. Press down on the finger pad of the Locking Lever and while holding it down
grasp the nozzles electric actuator assembly and rotate the front portion of the nozzle until the locking lever can
be released to engage the slot corresponding to the desired flow setting.
INSPECTION;
Inspect the nozzle after each use and at least monthly when not in use. Check the nozzle for any signs of
damage or contamination from the environment. Check the nozzle operation by moving the nozzle tip through
its entire range of motion several times. Grease if required (see Maintenance).
MAINTENANCE:
AFTER EACH USE; With the nozzle in the straight stream position, wipe clean the inside surface of the nozzle
tip at the discharge end, the surface of the center barrel directly behind the tip, and the outside surface of the
telescoping portion of the electric actuator. After cleaning apply a thin coating of lubricant (Dow Corning #7
Lubricant/Sealant) to the clean surfaces. Move the nozzle tip through its entire range of motion several times to
distribute the grease. With the tip in the wide fog position, wipe off any excess grease with a clean rag. Storing
the nozzle in the wide fog position will help protect the greased surfaces from exposure to the elements and
contaminants that may be attracted by the grease.
AS REQUIRED; Remove the two screws that retain the electric actuator and remove it. Remove the nozzle tip
and the nozzle tip o-ring. Use a mild soap & water solution to clean the outside surface of the center barrel, the
nozzle tip, and the o-ring. Inspect the o-ring and replace if worn or damaged. Apply a thin coat of lubricant
(Dow Corning #7 Lubricant/Sealant) to the o-ring, the outside surface of the center barrel, and the inside
surface of the nozzle tip. Reinstall the o-ring, nozzle tip, and electric actuator (see exploded drawing for Loctite
requirements). Move the nozzle tip through its entire range of motion several times to distribute the grease.
With the tip in the wide fog position, wipe off any excess grease with a clean rag. Storing the nozzle in the wide
fog position will help protect the greased surfaces from exposure to the elements and contaminants that may be
attracted by the grease.
