FMI CL1 User Manual

OVERVIEW:
Congratulations. Your Chloritrol® CL System from

Fluid Metering Inc. is the newest patented innovation
in 50 years for accurate, low maintenance injection of
sodium hypochlorite for water and wastewater
treatment. FMI’s CL, along with it’s CTS Chemical
Treatment System for caustic soda, are the easiest
chemical feed systems for water and waste treatment
in the world.

The patented Chloritrol® CL & CTS systems eliminate
check valves and/or peristaltic tubing typically present
in traditional hypochlorite metering systems, which are
the primary sources of downtime and frequent
maintenance . The CL & CTS Systems will never lose
prime, even against pressure, or air lock. The
Chloritrol

®

CL system consists of the CL Pump

Module and C100A Variable Speed Controller.

The CL Pump Module is a unique valveless duplex

FMI CeramPump® and an FMI RO “sipper” pump
direct coupled to a single variable speed drive motor.
The high-pressure CeramPump® injects the
hypochlorite directly into the main water stream, while
the RO “sipper” pump removes any gas generated
because of chlorine out-gassing, eliminating “gas lock”
and/or loss of prime.

The C100A Variable Speed Controller from Fluid

Metering, Inc. is specifically designed to interface

with the Chloritrol® CL Pump Module. This

controller provides a variable 0-90 VDC power
source, which is controlled either manually using a
panel mounted rotary dial, or electronically via a
4-20 mA control input.*

* Other commercially available controllers may work, however we

recommend contacting FMI for details.

CL SPECIFICATIONS

CL INSTALLATION & SETUP

The Chloritrol® CL prefers to “lift fluid” and therefore
should be located a minimum of 12 inches above supply
vessel. It should also be mounted in an accessible
location where the cover can be opened freely. Diagram 5
illustrates the recommended mounting location, as well as
a typical system configuration.

MOUNTING

Securely fasten the CL to a wall location with its right side
convenient to the hypochlorite supply vessel. There are 4
mounting holes (5/16” dia) on each side of the CL
enclosure. Utilize at least 2 holes on each side for most
secure mounting. Diagram 1 (left) shows the mounting
hole locations.

ELECTRICAL

On the upper left side of the Chloritrol® CL
enclosure is a 7/8” conduit opening for the electrical
supply (0-90 VDC source from the C100A or FMI
approved customer supplied voltage controller).

Note: See page 5 “Wiring Procedure” for
additional information regarding wire sizing.

1. With the power off, and the manual speed dial

turned fully counterclockwise to the “0” position,
connect the C100A to the 120 VAC power
source.

2. Connect the C100A Variable Speed DC Controller

to the Chloritrol® using 3 conductor cable.

3. If electronic speed control is being used, connect

the 4-20 mA source (typically a sensor or
analyzer), to the 4-20 mA input of the C100A.

Terminal Wiring

IMPORTANT NOTE: There are two (2) vent holes located at the top front of the enclosure (under the upper lip of the
enclosure cover). Do not close, seal, or obstruct these vent openings. They are designed to prevent hazardous gases from
building up in the enclosure over time. See Diagram 1.

START UP / PUMP CALIBRATION
Mechanical Adjustment:
Note: Your CL unit comes factory set at 50% flow.

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 6
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 ON/OFF
switch to the “ON” position and set the rotary dial to 6.
Turn On and measure discharge flow. Adjust flow as
necessary.

For speed control from an external 4-20mA source, set
the ON/OFF switch to the “AUTO” position.

FLUIDIC CONNECTIONS

1. Connect the supply tubing from the hypochlorite
supply vessel to the 1/4” NPT female CL Supply
Inlet fitting of the Chloritrol CL. Supply tubing

should be 1/4” to 3/8” ID semi-rigid translucent
tubing, LDPE (low density polyethylene) or

equivalent. Refer to Fluidic Overview Diagram 5.

Important Note: Do not use any fittings having

Buna-N seal elements. Only Viton® should
be used.

2. Connect the Return tubing from the 1/4” NPT
female CL Return back to the supply vessel.

Return tubing should be 1/4” to 3/8” ID semi­rigid tubing, LDPE (low density polyethylene)
or equivalent. Refer to Fluidic Overview
Diagram 5.

3. Connect 1/4” OD tubing (semi-rigid
suggested), from the CL Dispense (1/4” NPT

female) to the point of chlorination, typically

the groundwater well or water main.
