8393IV(2.0) “STINGRAY” MONITOR INSTRUCTIONS (CONTINUED)
5)
Open and close the water control isolation valve by means of the handle shaft. When the shaft is in
the “up” position, the valve is open and when in the “down” position, the valve is closed. There are
positive handle stops at the full open and full closed positions.
6)
The water control valve is not intended to be used for “throttling” the water flow. It should be fully
open or fully closed. ALWAYS open and close the valve slowly under flow conditions so as to
avoid creating a water hammer.
7)
The monitor should be drained after use in freezing temperatures. 1) Shut off the water supply
valve. 2) Open the monitor’s water control valve. 3) Turn the handwheel until the monitor’s
discharge is at its lowest vertical position. 4) Drain the monitor(s) and piping by means of an
automatic ball drip or other drain valve. 5) After the system has been drained, close the monitor’s
water control valve and place the monitor discharge back in the desired position.
Maintenance:
1)
Move the monitor and valve through its entire range of motion monthly. At this time, inspect the
monitor for proper lubrication, especially in corrosive environments or in climates where ice could
form in the valve. Keeping the gearing and rotation joints well lubricated is important.
2)
Every 3 months use a general petroleum based grease to lubricate the monitor through the two
grease fittings until all contaminated grease has been expelled. Wipe off the expelled grease. One
fitting is on the horizontal swivel and the other is on the end of the worm gear. Rotate the vertical &
horizontal joints 45 degrees at a time through their entire range of motion while applying the grease.
3)
If the monitor is subjected to vibration, check all fasteners and set screws for signs of loosening. If
necessary, secure them with a “Loctite #242” or similar type of adhesive product.
4)
For repair parts, please consult the assembly drawing and contact your Elkhart Brass dealer, or
contact Elkhart Brass Mfg.
5)
Maintain the monitor paint as dictated by use and by the environment. The factory-applied paint is a
red (RAL 3003) urethane enamel.
