Instructions How To Assemble The Float And Arm To
The Franklin BL Valve And How To Adjust The Valve
The Franklin Valve is already attached to the waterer. The float and arm assembly is with the hardware
kit. They are packaged separately to prevent undue wear to the valve caused by the arm bouncing up
and down during shipping.
The float and arm are attached to the valve by a thumb screw. The float can be positioned either closer
or further away from the valve (see photo below left for the two float positions). Further away increases
the shut off force of the valve. However depending upon which waterer is being used, the closer position
may be required to maintain proper clearance for the float to the side of the waterer. A clearance of at
least 1/2" should be maintained to ensure smooth operation of the valve.
When attaching the float arm to the valve, be sure to attach the arm to the correct side of the valve. The
grooves on the valve and float arm must match. Please note that the valve has coarse grooves on one
side and fine grooves on the other. The fine grooved side is used with the float arm (see below right for
details).
To adjust the water level in the waterer, loosen the thumb screws and position the float and arm so that
the valve is turned off when the water is at the desired level (see photo below). It may take a couple of
adjustments to get the correct level (1-1½" below the top of the trough). To speed the adjustment
process, remove the drain plug and drain a little water out so that the valve turns on. Put the drain plug
back and let water fill until the valve shuts off. If the level is not correct, repeat the process until the
correct level is obtained and then replace the float cover. Your waterer is now ready for use.
