1.3. Restrictions for use
The sample must not contain any particles, which may block the
flow cell. Sufficient sample flow is coercive for the correct function
of the instrument.
If the sample contains only little disinfectant concentrations, or
there is the danger of biological growth, we recommend to use the
optional Cleaning module from Swan.
WARNING
Health hazard
Some reagents are etching and can cause severe burns or eye
damage.

Measurement
The AMI Codes-II analyzer is a complete monitoring system for the
automatic, continuous measurement and dosing control of chlorine
and other disinfectants based on the DPD colorimetric method
AWWA 4500 Cl-G and on EN ISO 7393-2.
It can be used for measuring disinfectants in:
Potable water
Swimming pools
Cooling water
Effluent
Seawater
It is also applicable for water containing additives like corrosion inhibitors, cyanuric acids and antiscalants.
For the determination of free chlorine, chlorine dioxide, bromine
and iodine the reagents:
Oxycon on-line DPD
Oxycon on-line Buffer
are needed.
The measurement of monochloramine or ozone requires an addi-
tional reagent:
Oxycon on-line KI; which is added to Oxycon on-line Buffer

Product Description
Fluidics The sample flows through the sample inlet [F] and the filter vessel
[G] into the constant head [A]. Adjust the flow regulating valve [D]
so that always a small part of the sample flows through the overflow
tube [B] into the drain [H]. A part of the sample flows through the
photometer inlet [C] into the mixing chamber [E], where the reagents [J] and [K] are added by the peristaltic pump [O] and mixed
with the sample. The mixed sample flows through the photometer
[N] and disinfectant is measured. If KI and Buffer are mixed in the
reagent canister [K] monochloramine is measured.
After the measurement the sample flows through the outlet of the
photometer where it will be aerated through air inlet [P] to generate
bubbles. Then the sample flows through the bubble detector [M]
into the photometer drain [I].

Time
interval of a
measurement
The measuring interval can be set between 1 and 12 minutes. The
time sequence of a measurement with a measuring interval of
5 min is shown in the diagram below.
The blue bar represents the sample which flows continuously
through the photometer. A short time before the measurement
starts, a zero point measurement is performed. Then the peristaltic
pump starts and a small portion of the reagents [J] and [K] is
pumped into the mixing chamber. Shortly after, if the mixture is in
the photometer, the sample is measured.

Code, all state and local codes, and all plant codes and standards
for electrical equipment.
On site requirements
Installation Mount the instrument in vertical position.
Electrical Wiring Do not switch on the Instrument until all electrical connections
If ordered:

100– 240 VAC ( 10%), 50/60 Hz ( 5%) or 24 VDC (±10%),
isolated power outlet with ground connection and 30 VA.
Sample line with min. 10 l/h and 0.15 – 2 bar.
Waste line with pressure free drain.
Display should be at eye-level.
Mount the filter, filter vessel, and constant head cover. Connect the
sample and waste line. See Connecting Sample and Waste, p. 17
have been completed.
Connect all external devices like limit switches, current loops and
pumps.
Connect power cord.
See Electrical Connections, p. 24
See Install the Option pH, p. 20
Insert the suction lances.
Lock pump tubes.
Turn on the sample flow and wait until the flow cell is completely
filled.
Switch on power.
Start <Fill system>. See 4.4., 2 36.
Program all parameters for external devices (interface, recorders,
etc.). Program all parameters for instrument operation (limits,
alarms, measuring interval).
If ordered: Calibrate pH sensor. See Process pH, p. 51.

quirements
3.3. Connecting Sample and Waste
Make 3 manual measurements. Use a high quality photometer,
e.g. Chematest from Swan. Calculate average value and compare
this value to the value indicated by the AMI. If necessary, correct
the value. The zero point is done automatically before each measurement.
The first part of this chapter describes the preparing and placing of
the system for use.
The instrument must only be installed by trained personnel.
Mount the instrument in vertical position.
For ease of operation mount it so that the display is at eye
level.
For the installation a kit containing the following installation
material is available:
– 6 Screws 6x60 mm
–6 Dowels
– 6 Washers 6.4/12 mm
The instrument is only intended for indoor installation.
For dimensions see Dimensions, p. 14.
