The pump is suitable for vertical or horizontal installations.
Connect a rigid or flexible pipe to the 1¼" delivery of the pump.
The maximum submersibility of the pump depends on the length of the power cable: 12m (39.4 ft) in the case of a cable 15m (49.2 ft) long; 7m
(23 ft) in the case of a cable 10m (32.8 ft) long. Check the details on the technical data plate, as shown in figure 4.
In order to always guarantee a good water flow, it is advisable not to exceed the following heights between the service taps and the pump (see
figure 7).
To facilitate installation in the tank, it is possible to remove the power cable and/or pass it through another passage hole. To
remove it, follow the instructions on the product's quick guide. The electrical cable has a quick connection.
Have this operation carried out by qualified personnel. Check the earth connection before commissioning the product.
The pump has:
An air vent valve (see figure 8). This valve allows the pump to prime in a very short time. If the water level is lower than the valve level,
•
some water may escape from the vent valve.
A small spring and diaphragm expansion tank (in the case of DTRON2 pumps). This limits the number of pump restarts and
•
compensates for small system losses. The tank protects the pump in case of water hammer. The tank does not require any refilling or
maintenance.
An overpressure valve, which prevents water hammer. In case of ice in the delivery pipe with a submerged pump, this valve protects
•
the pump from breakage.
Installation in a well.
Install the pump so that the pump suction is at least 1 m (3.28ft) above the bottom of the well to prevent the intake of sand and impurities. Use
rigid metal pipes to hang the pump and secure the pipes with brackets at the top of the well.
Installation in a tank
The minimum dimensions for the pump passage in the collecting tank are 180x185 mm (7.09x7.28 in).
Hold the pump slightly up from the bottom so as to avoid possible noises/vibrations transmitted to the tank.
The pump will make noise if it is placed on the bottom of the tank.
To avoid obstruction of the suction passages, it is recommended to check periodically that no dirt has accumulated in the
collection trap (leaves, sand, etc.).
Installation with FLOAT KIT (accessory)
In the case of DTRON2 pumps, an NFC level float can be added.
This accessory, once placed in the appropriate seat in the pump, communicates with the electronic board without the aid of electrical
connections.
The minimum overall dimensions of the pump with float inside a well or tank are as follows:
The minimum recommended distance between the end of the pump float and the wall is 3cm (1.18 in) (see figure 10).
The minimum recommended distance between the float of the suction pipe and the wall (in the case of version X) is 10cm (3.94 in) (see figure
10).

FIRST INSTALLATION
The pump and the control panel, if present, must be connected to the same power mains, avoiding their being galvanically
separated, as for example due to the presence of open isolation transformers or switches, even single-phase ones.
In particular condominium or industrial contexts, where single-phase users can be connected to different phases of the three-
phase distribution provided by the public operator, the control panel and the pump might not be able to communicate.
