Installation and assembly
The group can be installed vertically or horizontally on a solid flat surface by screws and
antivibration washers, using the existing holes in the engine, in order to avoid noise
and vibration.
Be placed as close to the liquid level to obtain the minimum suction path,
and reducing losses. It should be safe from any possible flooding and well ventilated.
(Dry ventilation)
Install a manometer on the Impulsion to set the pressure of the pump.
Assembly of pipes
The suction and discharge pipes should have a diameter the same or superior to the inlet of the
pump. They must be hermetic, air intake causes suction loss in the pump.
Reduce to a minimum any elbow joints, strangling, all of which increase the load losses. Always
install a filtering mesh adequate for the fluid to be pumped on the suction pipe. Although it is
not absolutely necessary, it is convenient to install a foot valve.
Install a manometer on the impulsion and a meter in aspiration.
Neither the suction nor the discharge pipes should rest their weight on the pump.
Electrical connection
The electric cable should correspond to EEC standards or to type HO7RN-F as per VDE
0250.
The electrical installation should be protected by means of a differential switch.
Single-phase motors are incorporated with thermal protection.
For three-phase motors the end-user should foresee protection as per the legislation in
force.
The connection symbols (see drawing) make the electric connection easy.
Controls prior to initial start-up
Check that the tension and frequency of the mains correspond to those indicated
on the characteristics plaque. Make sure that the motor shaft turns freely.
Check that the sense of rotation of the motor coincides with that indicated on the fan
cover.
On three-phase motors, if the sense of rotation is incorrect, invert two phases on the
protection panel.
