Drilling template for the wall bracket After about 800 hours of operation, tighten the bolts of the pump body by using a tightening torque of 3 Nm.
In making the hydraulic connections it is necessary to comply with the following instructions:

• The BOTTOM FILTER should be installed at a distance of about 5-10 cm from the bottom, in order to avoid clogging;
• The installation with the pump below the liquid level is recommended for pumps with very low flow rates. In particular when dosing products that have a tendency to develop gases (ex: sodium hypochlorite, hydrazine, hydrogen peroxide…)
• If it is necessary to use tubes longer than those supplied with the installation kit, they must always have the same dimensions as those supplied with the pump. If the DELIVERY PIPE is exposed to direct sunlight, it is recommended the use of a black UV-resistant pipe;
• It is advisable for the INJECTION POINT to be placed higher than the pump or the tank.;
• The INJECTION VALVE supplied with the pump, should always be installed at the end of the dosing-flow delivery line.

STARTING UP THE PUMP

Once you have checked all the above operations, you are ready to start the pump.
Priming

• Start the pump
• Open the priming coupling by turning the knob anticlockwise and wait for the liquid to flow out of the hose connected to it.
• Once you are sure that the pump is completely filled with liquid you can close the coupling and the pump begins to dose.

TROUBLESHOOTING

The pump is running regularly but the
dosage was interrupted| The valves are clogged| Clean the valves or replace them if it’s not possible to remove the deposits
Eccessive intake height| Position the pump or the tank so as to reduce the intake height
The liquid is too viscous| Reduce the intake height or use a pump with a higher flow rate
Insufficient flow rate| Leaky valves| Check the tightness of the nuts
The liquid is too viscous| Reduce the intake height or use a pump with a higher flow rate
Partial clogging of the valves| Clean the valves or replace them if it’s not possible to remove the deposits
Irregular pump flow rate| Transparent PVC tube for delivery| Use the opaque PE tube for delivery
The diaphragm is breaking| Excessive back pressure| Check the system pressure. Check if the injection valve is clogged. Check if there is a clogging between the discharge valves and the injection point.
Operation without liquid| Check the presence of the foot filter (valve)
The diaphragm is not fixed properly| If the diaphragm has been replaced, check its proper tightening
The pump does not turn on| Insufficient power supply| Check if the values on the plate of the pump correspond to those of the electrical network.

Paragraph 1 – Manual dosage

pressing simultaneously.

Display during operation Paragraph 2 – Proportional Dosage to a 0/4-20 mA signal

| The pump proportionally doses at a signal of (0)4-20 mA. By default, the pump interrupts the dosage at 4 mA and doses at the maximum set frequency when it receives 20 mA. These two values can be modified during programming. The maximum frequency can be modified during operation by pressing simultaneously to modify the flow rate.
To view the current reading for the mA input, scroll the menu items to In mA.
For an input signal of less than 0.2 mA the alarm LED turns on to indicate the absence of signal.

Display during operation

| The pump proportionally doses at a signal of 20-4(0) mA. By default, the pump interrupts the dosage at 20 mA and doses at the maximum set frequency when it receives 4 mA. For an input signal of less than the minimum value – 0.2mA (fixed threshold) (Ex. 4-0.2= 3.8mA) the alarm LED turns on to indicate that the minimum value has been exceeded, but the pump continues to dose at the maximum frequency. These two values can be modified during programming. The maximum frequency can be modified during operation by pressing simultaneously to modify the flow rate.
To view the current reading for the mA input, scroll the menu items to In mA.
For an input signal of less than 0.2 mA the alarm LED turns on to indicate the absence of signal and the pump interrupts the dosage.

Display during operation Paragraph 4 – Proportional to External Impulses (multiplication)

| The pump doses proportionally to an external signal (ex: water meter pulse- sender). For every signal received, the pump runs the programmed “n” number of strokes. The pump automatically sets the dosage frequency, adapting it to the time that passes between two successive signals. It is possible to set the time (timeout) in seconds, beyond which the pump resets the interval counter in order to avoid dosages over excessively long periods of time. The pump has a memory function which detects the reception of a signal during the dosage. If set to Off, it only detects the signal; if set to On, it detects and memorizes the impulses, then executes them when has finished receiving the signals.
The “n” value can be changed during operation by pressing simultaneously.

Display during operation Paragraph 5 – Proportional to External Impulses (division)

| The pump doses proportionally to an external signal (ex: water meter pulse- sender). For every “n” signals received, the pump runs a stroke. The “n” value can be set during programming. By programming the “n” value, you set the % of maximum dosage; during operation this value can be modified by pressing simultaneously.

Display during operation Paragraph 6 – Proportional to External Impulses (batch dosage)

| The pump doses proportionally to an external signal (ex: water meter pulse-sender). In this case, you can set the quantity to be dosed in mL and the period of time necessary to complete the dosage.
The dosage can be started manually by pressing or through a remote command.
You can press to interrupt the dosage. The dosage already made can be reset to zero by pressing or restarted by pressing again.
The quantity to be dosed can be modified during operation by pressing simultaneously to modify the flow rate.

Display during operation Paragraph 7 – Proportional to External Impulses (ppm dosage)

| The pump doses proportionally to an external signal (ex: water meter pulse-sender) by automatically calculating the ratio between the input signals and the pump strokes according to the programmed ppm value. The data to be inserted are the ppm value, the pulses/liter ratio (or liter/pulse) of the counter and the concentration of the product to be dosed.
The dosage frequency can be modified during operation by pressing simultaneously.

Display during operation Paragraph 8 – Timed Dosage (Frequency signal input “TRIGGER” activated)

| After receiving the set Trigger signal, the pump doses a quantity that can be programmed in mL. It is possible to set a delay time before dosage (Delay) and an interval between subsequent dosages (Interval) as shown on the diagram:For example, by setting the interval Interv.= 0 you will get a system in which the programmed quantity is dosed after each TRIGGER signal (with the eventual delay set):You can start the dosage by pressing the + key, which practically simulates the Trigger signal.
The Trigger signal can be set to N. Open (it is activated when the input is switched from open to closed mode) or to N. Closed (it is activated when the input is switched from closed to open mode).
The Trigger signal is locked during the dosage (its reception is neither stored nor managed).
The Pause input (Remote Control) cannot be programmed and its activation locks the dosage, while the subsequent deactivation makes the system wait for the Trigger signal for a new dosage.
The dosage frequency can be modified during operation by pressing simultaneously.

Display during operation Paragraph 8 – Timed Dosage (Frequency signal input “TRIGGER” not activated)

| The pump doses a programmed quantity in mL. It is possible to set a delay time (Delay) for the pump start up and an interval between subsequent dosages (Interval) as shown on the diagram:The Delay and Interv. times are in dd.hh.mm format (days.hours.minutes)
The Pause input can be programmed in three different modes:
1. Freeze Time: with the pause activated, the system stops the current time count and restarts the count when the pause is deactivated
2. Pause Dosing: with the pause activated, the system continues to count the time and stops the dosage.
3. Restart Timer: with the pause activated, the system stops the dosage and when the pause is deactivated the count restarts
from the beginning.
The dosage frequency can be modified during the pump operation by pressing simultaneously.

Display during operation Paragraph 9 – Weekly timed dosage You can program 10 dosages for the entire week. Press from “Weekly Dos.” to enter the programming mode in order to program the dosages.

1. Number of program: press to modify and then press to confirm.
2. Dosage schedule: press to modify and then press to confirm.
3. Quantity to be dosed: press  to set the value in “mL” and then press to confirm.
4. Dosing time, i.e. the period of time (in seconds) in which the quantity previously programmed will be dosed: press  to set the value in seconds and then press to confirm.
5. Setting the dosage relay: press to modify the values and then press to confirm; in “Off” mode the relay does not stay off (open); in “after” mode, the relay is closing when the dosage is activated and stays closed, when the dosage is finished, for a period of time (in seconds) that you can set by pressing the key and then confirm by pressing the key. In “before” mode, the relay is closing before the dosage activation time, for a period of time (in seconds) that you can set by pressing the key and then confirm by pressing the key.
6. Activation days, i.e. the days in which you want the set program to be active (start time, quantity, dosage time and relay operation mode). Press to modify the option, then press to activate/deactivate the dosage, then press to change the day of the week. Press to confirm and automatically pass to the next program.
   If you need to configure the new program, repeat the above procedure, otherwise press to return to the main menu.
   On the main menu the next step is to set the clock; press to modify the option, then press to set the values and then press to confirm. In sequence, you can set the day, the hour and the minute. Of course, the day and the time set are those to which the programming will refer.
