After around 800 hours of work, tighten the bolts in the pump body, applying a tightening torque of 4 Nm.
When making the plumbing connections, make sure that you follow the instructions below:
The FOOT FILTER must be installed so that it is always positioned 5-10 cm from the foot, in order to prevent
-
any deposits from blocking it and damaging the hydraulic part of the pump;
The pumps come as standard with inlet and outlet pipe that are sized to suit the plumbing characteristics of the
-
pump. If you need to use longer pipes, it is important that you use pipes of the same dimensions as those
supplied with the pump.
For external applications in which the DELIVERY PIPE may be exposed to the sun's rays, we recommend
-
using a black pipe 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 dosage flow
-
delivery line.
START-UP
Once all the aforementioned operations have been completed, the pump is ready to be started.
Priming
Start the pump
-
- Open the priming connector by turning the knob in an anticlockwise direction and wait for liquid to come out of the pipe
connected to it.
Once you are sure that the pump is completely full of liquid, you can close the connector and the pump will begin to dose.

The pump must be connected to a power supply that complies
with that indicated on the label on the side of the pump. Failure to
respect these limits may cause damage to the pump itself.
Input A = power
supply
The pumps have been designed to absorb small over voltage.
Therefore, in order to prevent the pump from being damaged, it is
always preferable to ensure that the pump does not have a
power source shared with electrical appliances that generate high
Input B = Level
voltages.
Connection with the three-phase 380V line should only be
made between phase and neutral. Connections must not be
made between phase and earth.
