The brass threads are housed in technopolymer seats. When making the connection watertight by adding material (e.g. Teflon,
hemp,...) ensure that the gasket is not too thick: under the action of an adequate tightening torque (e.g. long handled pipe
wrench), the excess material could exert abnormal force on the technopolymer seat, damaging it irremediably.
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. 2.1.2).
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.

2.1.2. Loading Operation - Installation above head and below head

Installation "above head" (par. 2.1.1): access the technical compartment and, using a screwdriver, remove the filling cap (Fig.3). 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 paragraph
2.1.1) has been placed close to the system entry door, the quantity of water with which to fill the system should be 0,9 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 (0,9 litres + ...).
Installation "below head" (par. 2.1.1): 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) enough to vent the trapped air allows the system to load
completely. You must survey the operation and close the loading door as soon as the water comes out (however it is recommended to fit a check
valve in the section of the suction pipe and to use it to control the loading operation with the cap open). Alternatively, in the case where the suction
pipe is intercepted by a closed valve, the loading operation may be carried out in a similar way to the one described for installation over head.

2.2 - Horizontal Configuration

Screw the 4 rubber feet supplied loose in the package into the brass
seats in face E. Put the system in place, taking into account the
dimensions in Fig.8.
• The distance of at least 10mm between Face B of the system and
an obstruction is obligatory to let out the power supply cable to the
mains socket.
The distance of at least 200mm between Face A of the system
and an obstruction is recommended so as to be able to remove
the door and gain access to the technical compartment.
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.

2.2.1 Hydraulic connections

Make the connection at input to the system through the mouth on Face C marked "IN" in Fig. 8 (suction connection). Then remove the cap using
a screwdriver. Make the connection at output from the system through the mouth on Face C marked "OUT 1" in Fig. 8 and/or through the mouth
on Face F marked "OUT 2" in Fig. 8 (delivery connection).
In this configuration either of the 2 mouths can be used as an alternative to the other (depending on the convenience of the installation), or
simultaneously (dual delivery system). Then remove the cap(s) from the door(s) you intend to use 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.
