Pump installation
Install the pump away from heat sources, in a dry place and at a maximum ambient temperature of 40°C. The minimum
operating temperature of the pump depends on the liquid to be dosed, as the liquid must remaining a fluid state . If the pump
has been stored at an ambient temperature of less than 0°C, make sure that any water present in the pump head is in a
liquid state before starting up the pump.
Locate the pump as shown in fig.2 taking into account that it can be located over or under the liquid level within a
maximum difference of 1,5 meters. The injection point must always be located higher than the liquid to be dose.
If the plant being treated operates at atmospheric pressure (free discharge additive) and the additive tank must be
placed higher than the injection point (Fig. 2a),check periodically that the injection valve is operating correctly, as excessive
wear could cause additive injection by liquid loss (even when the plant is not operating). If the problem persists, insert a
correctly calibrated counter pressure valve C between the dosing pump and the injection point (Fig. 6).
For liquids that give off aggressive exhalations, do not install the pump over the tank unless the tank is hermetically
sealed.

Electrical scheme

Respect the regulations in force in different countries concerning the electrical installation. If the power cable has no
plug, the equipment must be connected to the power supply using an omnipolar switch with a minimum distance of 3 mm.
Before accessing the power connection devices, all power circuits must be interrupted.
