A switch (shown in the figure) that regulates the dosing mode of the pump
is present in the part relative to the electrical connections on the circuit.
The two different modes are:
Constant (switch in position C)
The pump constantly dispenses the percentage selected with a
potentiometer.
Proportional (switch in position P)
The pump doses proportionally to the input signal (Pulse emission meter).

After around 800 hours of work, tighten the bolts on the pump body, applying a tightening torque of 3 Nm.
When making the plumbing connections, make sure that you follow the instructions below:
-
The BOTTOM FILTER must be installed so that it is always positioned 5-10 cm from the bottom, in order to
prevent any formation of deposits.
- Installation of the pump suction head is
recommended for pumps with very low flow rates. In particular, when dosing
products which develop gas (e.g. sodium hypochlorite, hydrazine, hydrogen peroxide, etc.).
- If you need to use longer hoses than those provided in the installation kit, it is important that you use hoses of the same
dimensions as those supplied with the pump. If the DELIVERY HOSE may be exposed to the sunʼs rays, we recommend
using a black hose able to withstand ultraviolet rays
-
It is advisable to position the INJECTION POINT higher than the pump or tank.
-
The INJECTION VALVE, supplied with the pump, must always be installed at the end of the delivery line on of the dosing
flow.
