1. DESCRIPTION

The A-LEGIO SENSE panel has been designed to control the proliferation of legionella and other hydro diffused pathogens through an ON / OFF or proportional dosage of sodium hypochlorite or chlorine dioxide at the same time as a dosage of an anticorrosive conditioner.

In general, it is composed of:

1 AE-START + CL instrument for the measurement of free chlorine;
1 pump HC151 + (PImA model) to dose an inhibitor (anticorrosive) product controlled by a pulse emitting counter;
1 pump HC151 + (PimA model) with automatic air purge to dose a disinfectant product (sodium hypochlorite, etc.) controlled by the AE-START + CL instrument;
1 membrane amperometric probe for the determination of free chlorine;
1 modular HT probe holder, proximity sensor and flow regulator;
1 HT prefilter.

For the pump managed by the chlorine measuring instrument, the dosage mode set in the factory is the proportional one: the dosage is proportional to two mA values (4mA and 20mA).

2. PROGRAMMING THE PANEL

After installing and connecting all the required probes and devices for the purchased panel, follow the programming instructions set out in the pump and instrument manuals.

A list summarising the operations to follow for each panel is provided below.

2.1 HC151+ PUMP MENUS AND PROGRAMMING

Please refer to the HC151+ pump manual.

2.2 AE-START+ INSTRUMENT MENUS AND PROGRAMMING

Please refer to the AE-START+ instrument manual.

3. PROBE INSTALLATION AND MAINTENANCE

3.1 CL(J) 4-20 mA PROBE

1. Take the CL(J) probe out of the package and unscrew the membrane cap on the lower part of the probe:

2. Lower the rubber ring on the membrane cap before filling it with the electrolyte gel provided in the package:

3. Immerse the probe in the cap, being careful to prevent any excess electrolyte from spilling over (if so, rinse).

4. Unscrew the top part of the probe and connect the bipolar cable to the probe and the instrument’s CL terminal box:

5. Screw the top part back in place and insert the probe in the proper probe holder.

6. Secure the probe in place on the probe holder:

3.2 CL(J) PROBE with mV signal

To fit the CL(J-mV) probe to the modular probe holder, follow the instructions provided for the CL(J) 4-20mA probe; to prepare the probe for use, proceed as follows:

– Remove the protective cap and unscrew the membrane cap from the cell body. – Open the electrolyte bottle, screw the nozzle in place and allow any excess air to come out. – Fill the membrane cap with electrolyte to the level as shown (see figure); avoid the formation of air bubbles as much as you can.

– Eliminate any air bubbles by gently tapping the cap over a flat surface. Position the cell vertically on the filled membrane cap and screw the cap by hand until flush; proceed slowly to avoid damaging the membrane and be careful not to cover the breather hole with your fingers, because excess electrolyte should be free to flow out.

– Remove the electrolyte coming out with a damp cloth or rinse with water.
