CF1 Series
INSTALLATION / OPERATION / MAINTENANCE
Initial Adjustment CF1 Series Float Controls
A stilling well must be installed around the float and rod assembly. A short section of 8" pipe (PVC) mounted
vertically in the tank around the float and rod will work.
1. See parts sheet (other side of this sheet) for proper assembly of the float rod, float, and stop collars and for
threading into the Link Assembly of the CF1-C1.
2. Balance the Float Rod Assembly. This compensates for the buoyancy of the float rod in the water.
Temporarily remove float by removing float rod and float from the link assembly. Remove float from float rod,
reinstall rod assembly (leave stop collars on float rod) back into link assembly.
Adjust counterweight on rod to balance the weight of the float rod assembly less the float. Loosen setscrew on
counterweight and move weight in or out round rod remains horizontal without shifting. Tighten setscrew.
Check by pushing up or down on float rod assembly and seeing that entire assembly returns to balanced posi-
tion. Replace float between the stop collars. The counterweight size changes as float rod is lengthened.
Consult factory for more information.
3. Set Float High Level Shut-Off. Move float rod to "up" position. Adjust the upper stop collar on the float rod
assembly approximately three inches above the desire high water level. Move float rod to "down" position.
Adjust the lower stop collar on the float rod assembly approximately three inches below the desired low water
level. Tighten collar set screws.
4. If the closing level is too high, allowing tank to overflow, then the top stop collar on the float rod should be
lowered. If the opening level is too low, then the bottom stop collar should be raised.
If the counterweight has been properly adjusted the float will move freely on the float rod, without causing the
pilot arm to raise or lower, until the float actually contacts one of the stop collars.
5. For reference: with a new control and supply pressure less than 40 psi the maximum level differential avail-
able will be: 18 to 20 inches with PVC float and rod assembly and 48 to 50 inches with Stainless Steel or Brass
float and rod assembly.
6. If the valve or float control is controlling the level in a tank anywhere in a building, a floor drain with drainage
equal to maximum supply flow is required in case the valve and or float control is not properly maintained.
Installation Data
The float control is mounted above the high
water level in the tank. The valve is installed
in the line leading to the tank and is con-
nected to the float control pilot by tubing.
(Min. 3/8" tubing)
When line pressure is used to operate the
valve, tubing connections are made from the
float control pilot to the valve cover, and also
to the inlet side of the valve. An X43 “Y”
Strainer or X46 Flow Clean Strainer must be
installed in the inlet side of the valve. The
control may be installed at any elevation
above the valve, providing that the flowing
line pressure in psi is equal to, or greater
than, the vertical distance in feet between
the valve and the float control.
An independent source of air or water may
be used to operate the valve. The pressure
from this independent source must constant-
ly be equal to or greater than pressure at the
valve inlet. The independent source is con-
nected to the float control pilot in place of the
supply line connected to the inlet side of the
valve. If the Model 100-01 under the control
of the CF1-C1 is 8" or larger, auxiliary
Hytrols are required. Consult factory for
details.
NOTE:
A stilling well (Min. 8" I.D.) must be pro-
vided around the float.
