Mounting Instructions:
Note: The waterer is shipped with the float assembly installed on the right side
of the waterer bowl. The float assembly can be installed on either side of the
waterer to best suit your application. Carefully remove the square plastic plug
and the mounting nut and fibre washer from the float assembly. Reinstall the
float assembly on the left side and the square plastic plug on the right side of the
waterer before proceeding.
1. Mount the waterer to a flat rigid surface like a stall, fence, or post with the
mounting surface (back) of the waterer bowl as vertical/plum as possible. For
additional protection against damage from animals, mount the waterer near
an inside corner if possible.
Note: The waterer must be properly mounted to a vertical surface. The waterer
will not work properly laying on the ground.
2. Remove the float pin and float/arm
assembly from the waterer to gain access
to the mounting holes (see Figure 1).
3. Use the water bowl to measure and mark
the mounting holes at the desired mount-
ing location.
4. Drill a hole in each of the two (2) marked
locations.
a. If mounting the waterer with 3/8" lag
screws, use a 1/4" dia. drill.
b. If mounting the waterer with
3/8-16 through bolts, use a 13/32" dia.
drill.
5. Install the waterer as shown (see Figure 2 or 3).
Note: Always use the mounting plate provided.
6. Tighten the lag screws or through bolts securely and reinstall the float/arm
assembly and pin.

7. Wrap all supply line pipe thread connections (including the threads on the
valve) with Teflon
thread sealing tape and connect the water supply to the
®
float assembly. DO NOT overtighten any fitting or supply line connection.
8. Check to make sure the waterer fills and shuts off properly.
9. The water level is preset at the factory; however, minor adjustments can be
made to increase or decrease the water level in the waterer if desired.
To adjust the water level, remove float arm assembly by pulling out the
connecting pin, loosen the float mounting screw and nut with a screwdriver,
then rotate the float arm up or down to achieve desired water level. Make
sure you retighten the mounting screw and nut securely.
CAUTION: Rotating the arm too far up or failing to secure the float mount-
ing screw and nut may prevent the waterer from stopping the water supply
flow and run continuously.
OPERATING TIPS:
If the water flow does not stop...
1. Make sure water supply pressure is below 50 psi.
2. Make sure float arm moves up and down freely without binding.
3. Make sure float is not hitting the metal float cover when closed.
4. Remove float pin and float arm assembly:
a. Check for water inside the float. Replace SW23 float if necessary.
b. Remove any debris from valve tip or valve seal and test.
c. Replace SW8 seal and test. (An additional seal is provided on the side
of the float arm)
d. Check SW20 valve tip for chips, surface imperfections, or cracks.
Replace valve if necessary.
