TIGHTEN SCREWS
Tighten Screws:
1.
Tighten screws every fall.
2.
Tighten cover clip screws on top cover
casting.
3.
Verify cotter pins are in each end of
brass pivot shaft.
DRIPPING & OVERFLOW
A waterer that drips when it should be shut-
off most likely has sand or other sediment in
the control valve. Other causes could be an
obstruction which interferes with the
movement of the pivot beam or the control
valve is out of the adjustment. Follow the steps
A through C below to isolate and resolve the
dripping problem.
A. CHECKING FOR OBSTRUCTION
1.
To look for an obstruction start with the
cover and drinking bowl removed, check the
cross beam screws to make sure they are tight.
2.
The counterweight must be securely
mounted on the pivot beam.
3.
Next examine the brass pivot shaft. If a
cotter key is missing and the brass pivot shaft
has come out of position, reposition shaft and
replace the cotter key.
4.
Check the position of the beam lock lever
making sure it does not interfere with the
movement of the pivot beam or drinking bowl.
5.
Finally, check for obstructions below the
drinking bowl that prevents the free
movement of the pivot beam or the drinking
bowl. The brass shut-off valve on the water
supply line is usually the obstruction. Inspect
the water supply line for interference with any
moving parts.
B. ADJUSTING THE CONTROL VALVE
1.
Remove top aluminum casting.
2.
Lock the pivot beam with the beam lock
lever to close the valve.
3.
Remove drinking bowl.
4.
Open the brass shut-off valve by turning
counter clockwise.
5.
Using coin or screwdriver, turn control
adjustment screw ( 3/8” stainless steel screw in
brass bushing) clockwise until a very small
stream flows from the water spout tube and
breaks-up into drops about 3” below tube outlet.
Then turn control valve adjustment screw 1/4
counter-clockwise which will cause water to stop
flowing. Then turn the screw an additional 1/4
turn counter clockwise.
6.
Replace drinking bowl, release beam lock
lever, and observe water entering bowl.
Note:
If, after initial adjustment, water does
not completely shut-off and drips, lock the beam
lock lever and turn the control valve adjustment
screw another 1/4 turn counter-clockwise.
Continue this process at 1/4 turn intervals until
water shuts-off completely after refilling.
C. INSPECTING/REPLACING INLINE
WATER FILTER & CONTROL VALVE
If dripping and overflow continues and
there is no obstruction and the control
valve has been adjusted, you will need to
remove the inline water filter and control
valve to inspect for sediment or worn
components. Use the instructions below in
conjunction with the diagrams and
instructions on page 11.
1.
To remove the filter and control valve for
inspection you will need to shut-off electric
power and shut-off the water supply at the
brass shut-off valve.
2.
Next, unfasten the fitting connecting the
brass shut-off valve to the copper water supply.
3.
Then remove the nylon inline filter located
just inside the copper water supply tube. A
tool such as a pocket knife or needle nose
pliers may be required. Now if you see
sediment you will need to clean or replace the
filter. Also inspect the filter carefully for tears
and, if torn, replace the filter.
4.
Next remove the control valve to inspect
for sediment and worn valve parts. With the
power and water still off, remove the lead
weight then remove the cotter pin from the
tapered end of the brass pivot shaft and slide
the shaft out. The pivot beam and cage may
then be removed as a unit. Remove the brass
hex nut that secures the control valve to the
bracket.
5.
Next unfasten the water supply hose and
the copper water spout tube from each end of
the control valve.
6.
Unscrew the valve cap from the bottom
of the control valve to remove the valve stem
and stainless steel spring. Now rinse the
individual valve components thoroughly with
water. Sediment impeding the control valve
may not be visible.
