2 INSTALLATION AND TECHNICAL FEATURES
2.1 General regulations
Pump installation must be carried out as follows:

On a horizontal support (ex.: storage tank) or on the wall-mount bracket (optional) as
long as the pumps remains in a vertical po/- 15°.

Away from sources of heat in dry locations, at a maximum temperature of 45° C, and a
minimum of 0° C.

In a ventilated environment and easily accessible to an operator for periodic
maintenance.

Above the level of the liquid to be dosed, at a maximum height of 1.5 metres,
nevertheless bearing in mind that if the requirements of the system envision the need to
position the pump below the level of the liquid (positive suction head), in order to avoid
problems with the siphon, always use the injection valve or a counter pressure valve.

Do not install the pump above the tank when using liquids that emit fumes, unless it is
sealed shut.

2.3 Electrical connections
2.3.1 Power supply
CAUTION !!!!!
Verify that the earth system is perfectly functional and complies with the applicable regulations.
Ensure the unit is connected to a circuit protected by a highly sensitive (0.03A) RCCB circuit
breaker. If unsure please consult a competent electrician.Verify that the rated values of the pump
are compatible with those of the mains. Never install the pump directly in parallel with inductive
loads (e.g. motors/solenoid valves) if necessary, use an isolating relay.
There are 2 protection devices inside the pump: a varistor and a fuse.
