Electrical connection
Comply with standards in force in the different countries regarding electrical installation. If the power cord does not have
a plug, the equipment must be connected to the mains by means of an omnipolar disconnecting switch with at least 3 mm
distance between the contacts. All the supply circuits must be interrupted before accessing the connection devices (Fig.
3).
Hydraulic connection
The delivery fitting will always remain in the upper part of the pump from which the tube that goes to the system to be
treated will start. Therefore, the suction fitting will always be in the lower part of the pump, where the tube with the filter that
goes to the container of the liquid to be dispensed will be mounted.
1. Remove the seal on the ring nut (2)
2. Insert the tube (1) through the ring nut
(2) and the bushing (3)
3. Push the end of the tube (1) onto the
tapered spout of the nozzle (4)
making sure that the tube reaches
the end of the tapered part of the
nozzle
4. Move the nozzle (4) close to the fitting
(5)
5. Tighten the ring nut (2) on the fitting
(5)
Similarly, remove the pre-cut cap on the delivery (suction) side from the pump body, by previously removing the ring nut (2),
the bushing (3) and the nozzle (4). Then proceed by following the aforementioned steps 2 and 3. Lastly, move the nozzle on
the delivery (suction) side of the pump body and tighten the ring nut (2).
To prime the pump, connect the delivery pipe and follow the sequence shown in Fig. 5:
 connect the purge fitting on the pump body to a pipe which returns to the suction tank then unscrew the purge knob,
operating the pump in PRIMING mode (priming, see Chapter
 keep the purge valve B open until all the air contained in the tube and in the pump body has come out;
 close the purge valve.
In the event of difficulties in priming the pump, use a syringe to extract the additive from the purge fitting, decreasing the
number of pulses delivered by the device and respecting the safety requirements relating to the product to be dispensed.
