Energy Saving

Perform the assembly without mechanical stresses acting on the pump.
Avoid the installation in misaligned pipe work.
Install the pump with horizontal motor shaft axis (fig. A).
The direction of the water flow is indicated by the arrow on the pump
body, as shown in fig. B.
The motor body can be rotated in the positions shown in figure C.
Pay utmost care to prevent people from getting in contact with the
hot surfaces of the pump.
Rotate the motor body after having loosened the screws (fig. D).

3.2 electric connection
Pay attention not to damage the seal of the pump body.
The electric connection has to be performed by a qualified electrician in compliance
with the national regulations. follow the safety regulations.
The connection to the mains must be carried out in compliance with
the standards incorporating in the fixing wiring a disconnection device
from the supply mains having a contact separation in all poles that
provide full disconnection under overvoltage category III conditions.
All electric information concerning the circulation pump is born on the
signaling plate.
The connection cord must be laid in such a way as it cannot come in
contact with the hosing or the motor body. In case of use of the pump
with fluids at a temperature higher than 70 °C, use a connection cord resistant to
high temperatures.
Connect the power supply conductors to the terminals according to the diagram
given in fig. F.
Insert the terminal board (fig. G) in the proper seat (fig. H), connecting the red wire
with letter N and the blue wire with letter L. Screw the two screws (fig. I) and tighten
the sealing nuts (fig. L) to the fairlead.
The pump belongs to class II and therefore grounding is not necessary.
The pump does not require any external protection of the motor.
Compare the frequency and the voltage of the mains with the rating data.
