DIMENSION L - RISING LEVER OPENS VALVE
The 377 when installed according to these guidelines will provide a maximum water level in the tank that is 2-1/4 inches below the top of the
377. The 377 Float Cage must be installed with the axis through the 1-1/2 NPT pipe connections oriented vertically. The 326L or 322L Lever
Valve is located above the 377 in rising lever opens valve applications, and below the 377 in rising lever closes valve applications. The lever
valve must be installed with the fluid flowing in the correct direction. For proper operation in all applications, lever valves must be piped
according to the corresponding flow arrows, or inlet markings present on each valve (See Information Present on 326L Lever Valves section
or Information Present on 322L Lever Valves section for location of important information on valve). The lever valve must be installed in the
vertical position with the stem pointing upward. When the maximum desired water level in the tank is reached the 377 closes the lever valve
stopping the flow of water into the tank. When the lever valve is closed its lever is horizontal, the turnbuckle is vertical, the end of the 377
lever connected to the turnbuckle is at its lowest point in rising lever opens valve applications and at its highest point in rising lever closes
valve applications. Clearance must be allowed for each turnbuckle connection and lever rotation. There are four possible turnbuckle con-
necting holes on the lever.

INSTALLATION GUIDELINES
BEFORE YOU BEGIN
The guidelines presented here are for a typical tank filling application utilizing a 377 Float Cage and a Warren Controls Lever Valve. As
shown in the Typical Installation Drawings the 377 closes the Lever Valve when the water in the tank reaches the desired level. Since there
are numerous possible working configurations it is necessary for you to determine where the 377 and Lever Valve will be located before
you install them. The INSTAL
LATION GUIDELINES are presented for this purpose. Please read all guidelines thoroughly before
you begin.
