Installation and Start Up
General Information
Mount the FCA‐22 in a location where there is easy access to the analyzer and sensors. Install the
system in an area where vibrations, electromagnetic and radio frequency interference are minimized or
absent.
Do not mount in direct sunlight or areas of extreme heat. The FCA‐22 is suitable for outdoor use if
mounted with a protective cover or sunshield.
Sample Requirements
The constant head flow controller can adapt to changing sample flows between 10 and 80 gal/hr
(40‐300 L/hr).
Minimum flow: 10 gal/hr (38 L/hr)
Sample Pressure: 1 to 30 psig (0.1 ‐ 2 bar)
Temperature: 32° to 122°F (0° to 50°C)
Mounting and Connecting the Inlet and Drain fittings
The FCA‐22 is intended for wall mounting only. The sensors insert into the flow cells as shown in the
figures. A ¼" barbed fitting is provided for the sample inlet. If desired, a ¼"compression fitting can be
used. The sample inlet is ¼" FNPT. The sample drains through the ¾" FNPT hole at the bottom of the
CHFD. Attach a ¾" fitting to a length of soft tubing and allow the waste to drain to open atmosphere. Do
not restrict the drain line. The sample can be introduced after the sensors have been calibrated and
installed in the flow cells.
Powering the C‐22
Attach power as described in the C‐22 manual. Tighten the cable glands provide a good seal to the
cable.
Installing the Sensors
The FCA‐22 is supplied with the sensor cables pre‐wired to the analyzer. The FCA‐22 instrument and
sensors were calibrated at the factory and should be ready for use when assembled. However, changes
may have occurred during shipping and storage requiring recalibration. (See Calibration section below)
The pH sensor mounts in the Flow Cell using the supplied ¾" compression gland fitting. Remove the
protective cap and save it for future use, the cap contains a potassium chloride solution use care when
removing the cap from the sensor. Loosen the compression fitting to allow the sensor to spin freely in
the fitting. Insert the sensor into the flow cell and hand tighten the gland fitting. Retract the pH sensor
approximately ½" from the bottom of the flow cell and hand tighten the compression nut to fix its
position. The Chlorine sensor is held in the flow cell with a union nut. Remove the protective cap and
save it for future use. Slide the sensor into the flow cell and hand tighten the knurled nut.
