If the surface is not flat, unscrew the foot that is not touching and adjust its height until it contacts the surface so as to ensure the stability of the

system. The system must in fact be placed in a safe and stable position, ensuring that its axis is vertical: it must not be in an inclined position.

4.1.1 Hydraulic connections

Make the connection at input to the system through the mouth on Face F marked "IN" in Fig.7 (suction connection). Then remove the respective

cap with the aid of the accessory tool or with a screwdriver.

Make the connection at output from the system through the mouth on Face F marked "OUT" in Fig.7 (delivery connection). Then remove the

respective cap with the aid of the accessory tool or with a screwdriver.

All the hydraulic connections of the system to the plant to which it can be connected are of the threaded female type 1" GAS, made of brass.

If you intend to connect the product to the plant with fittings that have a diameter larger than the normal 1" pipe (for example the ring

nut in the case of fittings in 3 pieces), make sure that the 1" Gas male thread of the coupling protrudes at least 25mm from the above

diameter (see Fig.8).

With reference to its position with respect to the water to be pumped, the installation of the system may be defined "above head" or "below head".

In particular the installation is defined "above head" when the pump is placed at a level higher than the water to be pumped (e.g. pump on the

surface and water in a well); vice versa it is "below head" when the pump is placed at a level lower than the water to be pumped (e.g. overhead

cistern and pump below).

If the vertical installation of the system is of the "over head" type, it is recommended to fit a non-return valve in the suction section of

the system; this is to allow the operation of loading the system (par. 4.1.2).

If the installation is of the "over head" type, install the suction pipe from the water source to the pump in such a way as to avoid the

formation of goosenecks or siphons. Do not place the suction pipe above the pump level (to avoid the formation of air bubbles in the

suction pipe). The suction pipe must draw at its entrance at a depth of at least 30cm below the water level and must be watertight

along its whole length, as far as the entrance to the electropump.

The suction and delivery pipes must be fitted so that they do not exert any mechanical pressure on the pump.

4.1.2 Loading Operation - Installation above head and below head -

Installation "above head": (par. 4.1.1): access the technical compartment and, with the aid of the accessory tool (Fig.3_point 5) or with a

screwdriver, remove the filling cap (Fig.3_ point 6). Fill the system with clean water through the loading door, taking care to let the air out. If the

non-return valve on the suction pipe (recommended in par. 4.1.1) has been placed close to the system entry door, the quantity of water with which

to fill the system should be 2.2 litres. It is recommended to fit the non-return valve at the end of the suction pipe (foot valve) so as to be able to fill

it quickly too during the loading operation. In this case the quantity of water necessary for the loading operation will depend on the length of the

suction pipe (2.2 litres + ...).

Installation "below head": (par. 4.1.1): if there are no check valves between the water deposit and the system (or if they are open), it loads

automatically as soon as it is allowed to let out the trapped air. So slackening the filling cap (Fig.3_ point 6) ) enough to vent the trapped air allows
