FMI CTS Series - Manual (Page 3)

ADJUSTING FLOW RATE
Mechanical Adjustment: By adjusting the angle of
the high pressure pump head (pump head on right side
of drive) using the adjustment knob, piston
displacement can be increased and decreased, which
in turn will vary flow rate. Diagram 5 shows the
minimum (0%), maximum (100%), and factory set
(50%) pump head positions.
Electronic Adjustment: The C100A Variable Speed
Controller varies pump speed and has both manual and
electronic control modes.
For manual speed adjustment, set the C100A mode on
MANUAL and use the rotary dial to increase or
decrease pump speed.
FLUIDIC CONNECTIONS
The CTS has two 1/4” FNPT fluid connections.
The INLET (Supply) connection is a 1/4” FNPT fitting
located on the lower right side of the enclosure and
connects the CTS with the chemical supply reservoir
(carboy, tank, etc.) Inlet tubing is customer supplied and
should be semi-rigid and sized adequately to accommodate
the required flow rate to prevent cavitation. Minimum
recommended inlet tubing diameter is 1/2” I.D.
The OUTLET (Dispense) connection is a 1/4” FNPT fitting
located on the upper right side of the enclosure and
connects the fluid output of the pump to
the water source to
be treated, typically a water main. The CTS is designed to
pump against 125 psi backpressure, and therefore all
plumbing on the discharge side of the pump should rated for
250 psi. It is recommended that 1/4” O.D. polyethylene
tubing is used for the output tubing.

Installation Notes:
1) Be careful not to over-tighten fittings to the CTS
box as the bulkheads are made of PVC and may
crack.
2) For optimal performance, mount the CTS as close
to the source as possible and above it.
3) The CHLORITROL
®
was designed to overcome
backflow concerns typically associated with
diaphragm and peristaltic pumps. Because the
inlet and outlet fluid path of FMI’s CeramPump®
valveless piston pump are never interconnected, a
backflow check valve is usually not required.
However, local code requires a check valve on the
inlet side of the pump, refer to the “Tips &
Troubleshooting” section of this instruction
manual.
