PRINCIPLE OF OPERATIONS
The principle of operation of the peristaltic pumps is based on the pressure and subsequent release
of the internal tube by the roller mounted on the roller-holder, which is driven by the motor. The
dual action of pressure and release of the tube generates a suction force along the tube itself which
primes the liquid and guide it to the injection line.
The command is sent to the motor by the electronic unit according to the program, to the detected
measurement and to the absence of alarms / errors. These pumps are also equipped with a built-in
instrument, that detects and manages pH and redox measurements.
INSTALLATION
Install the pump in a dry area, at a maximum ambient temperature of 45°C, and place it such as to
allo w easy adjustment and maintenance operations. Wall mount the pump using the supplied
bracket. Secure the bracket to a vertical wall (±15°) and attach the pump.

It is recommended to place the tank of the product to be dosed below the pump, without
exceeding the maximum suction height (approx. 1.5 m). If the system is installed below the level of
the liquid, periodically check the status of the injection valve. If dosing a liquid that gives off fumes,
make sure the tank is sealed.
HYDRAULIC CONNECTIONS
Suction line (also see drawing)
1. Unscrew the fixing nut of the suction fitting located at the bottom left of the
pump body, marked with the entering arrow.
2. Cut the PVC Crystal tube and insert the tube fixing nut onto the tube.
3. Mount the tube on the conic hose of the suction fitting, pushing it to reach
the stop collar.
4. Secure the tube by screwing the tube fixing nut on the suction fitting of the
pump body.
5. Place the tube inside the tank and/or the suction lance.
6. Unscrew the tube fixing nut of the foot filter fitting.
7. Cut the PVC Crystal tube and insert the tube fixing nut onto the tube.
8. Mount the tube on the conic hose of the foot filter, pushing it to reach the stop collar.
9. Secure the tube by screwing the tube fixing nut on the foot filter fitting.
10. Screw the foot filter on the suction lance and/or place it in its working site.
Place the foot filter at a minimum distance of 5 cm from the tank bottom. If a dense
product is dosed, it is advisable to remove the internal filter, in order to facilitate the
aspiration.

4. Secure the tube by screwing the tube fixing nut on the injection fitting of the pump body.
5. Apply at the injection point of the pipeline a 1/2” GAS fitting, internally threaded (not supplied).
6. Garnish the thread with PTFE tape and screw the injection valve on the fitting.
7. Unscrew the tube fixing nut of the injection valve fitting.
8. Cut the PVC Crystal tube and insert the tube fixing nut onto the tube.
9. Mount the tube on the conic hose of the injection valve, pushing it to reach the stop collar.
10. Secure the tube by screwing the tube fixing nut on the valve fitting.
The injection valve also work sas non-return valve. Never disassemble it internally.

ELECTRICAL CONNECTIONS
Power supply: 230 V~, 50/60 Hz.
The mains circuit must be protected in accordance
with the relevant laws and regulations. Typically, the
protection is given by a 30 mA differential switch and
a breaker or 1 A fuse.
If a level control sensor is used, plug it to its connector
(see figure). Warning! If several pumps are connected
in parallel, always observe the polarity of the level
connection, not to endanger the proper functioning
of the system or damage the inputs!
Connect the measurement electrode to the BNC
connector.
CONTROL PANEL
Display during normal operations displays the measured pH or redox (mV); the following
messages may also appear:
- OFF the pump has been disabled by pressing the ON/OFF button
- LEU the level sensor consent is missing
- PAU the pump is “Paused” at start-up (also see “Configuration” section)
- ALL a dosage “Alarm” is active (also see “Configuration” section)
- UR measurement out of range, below the minimum value (Under-Range)
- OR measurement out of range, above the maximum value (Over-Range)
ON/OFF key enables/disables the system; press and hold for at least 3 seconds to enter the
CONFIGURATION mode

MEANING OF PARAMETERS
P1: This parameter allows to select the measurement type, pH or redox (mV). When setting P1=0
(pH reading with two decimal), please note that the two decimal places are visble only for
pH values below 10, because the display can show up to three digits. However, generally the
precision of pH measurements with one decimal is sufficient in most applications.

P2: This parameter allows to configure the working mode of level contact: 0 = NO (normally open,
standard configuration) 1 = NC (normally closed, fail-safe mode).
P3: This parameter allows to store the status of the ON/OFF button at the system shutdown: 0 = at
start-up the pump is always enabled 1 = at start-up the pump restores its status at shutdown.
P4: This parameter allows to set the pump working mode:
0 = OFF the pump is always off, independently from measured value: this option allowsto
monitor the measurement without intervening, for example during the plant start-up
1 = ON thethe pump is always on, independently from measured value: this option is used
to manually force the dosage, for example during the plant start-up or maintenance
2 = ON/OFF acid thethis option is typically used for acidification; the pump activates when
the measurement exceeds the “working threshold + ½ hysteresis” level, and deactivates when
the measurement falls below the “working threshold – ½ hysteresis” value
3 = Proportional acid the pump is definitely active when the measurement is greater than
the “working threshold + ½ hysteresis” level, and definitely off when measurement is lower
than the “working threshold – ½ hysteresis” value, while for measurements between these
limits, the operating time of the pump is proportional to the distance of measurement from
the limits. The time base is fixed (90 seconds) and operation follows the trend shown in the
table below:
Measurement = pH ; Working threshold = 7.20 pH ; Hysteresis = 0.40 pH
Measure <= 7.00 7.10 7.20 7.30 >= 7.40
% dosage 0 % 25 % 50 % 75 % 100 %
Pump ON never 23 seconds 45 seconds 67 seconds always
Pump OFF always 67 seconds 45 seconds 23 seconds never
4 = ON/OFF chlorinethis option is typically used for chloration or alkalinization; the pump
activates when the measurement is lower than the “working threshold – ½ hysteresis”
value, and deactivates when the measurement exceeds the “working threshold + ½
hysteresis” level
5 = Proportional chlorinethe pump is definitely active when the measurement is lower
than the “working threshold – ½ hysteresis” value, and definitely off when measurement is
greater than the “working threshold + ½ hysteresis” level, while for measurements between
these limits, the operating time of the pump is proportional to the distance of measurement
from the limits. The time base is fixed (90 seconds) and operation follows the trend shown
in the table below:
Measurement = Redox ; Working threshold = 680 mV ; Hysteresis = 20 mV
Measure <= 670 675 680 685 >= 690
% dosage 100 % 75 % 50 % 25 % 0 %
