4. Installation
4.1. Permanent pump
Pumps should not rest on the bottom of the well, nor be placed very near the walls. To avoid this, suspend the pump
from a cable through the handle on the upper part. (Figures 1 and 2).
Never suspend the pump by the electric cable or the discharge line. The pump should be partially submerged for
proper cooling.
Make sure the well flow is more than what is required, to prevent the pump from running dry or from starting and
stopping more often than normal.
If the well water level fluctuates significantly, we recommend installing electroprobe level equipment.
So as not to ruin the motor supply cable and electroprobe level cables, attach them to the discharge line with
clamps after lowering them into the well.
4.2. Discharge line assembly
Pumps are supplied ready to be connected a 1" line. However, if the geometric height is considerable and long,
winding paths exist, we recommend using lines with a larger diameter, to avoid load losses through friction as much
as possible and to obtain the best hydraulic performance possible.
The ACUAPLUS kit provided already has a built-in retention value to keep the installation pressurised every time
the pump stops.
Installing other retention valves is not necessary. If a plastic hose is chosen instead of a metallic line, ensure that
it supports the pressure provided by the pump. Prevent the hose from becoming twisted because, in addition to
preventing the desired flow, proper pump functioning will be hindered.
The lines must never rest their weight on the pump. Ensure that there are no water leaks in the installation.
4.3. ACUAPLUS Kit assembly
Kit assembly should be performed in the discharge line, before the first water intake, and be placed in a dry,
ventilated space. A 3-piece, rapid-switch unit is provided to make attaching the line easier. (Figure 3)
The Kit comes with a manometer and an expansion tank to prevent rapid drops in installation pressure. These 2
accessories must be assembled with the fittings and joints provided. (Figure 3)
For proper installation, bear in mind that the water must always flow in an ascending vertical or horizontal direction,
never in a descending vertical one.
Mount the Kit directly in series with the discharge line, as shown in Figures 1 and 2. Make sure the gaskets are
watertight (for example, with Teflon tape).
The weight of the discharge line must not rest on the Kit. To ensure this does not happen, install a flexible grid
between the Kit and the line. (Figure 4)
WARNING: For correct Kit functioning, the retention valve must be able to act freely. The measurements
indicated in Figure 5 must therefore be complied with strictly.

Electrical connection

CONNECTING THE PUMP TO THE MAINS
The electrical installation should have a multiple separation system with contact openings ≥ 3 mm. System protection will
be based on a differential switch (IΔn = 30 mA).
An authorised technician must connect the pump to the Kit electrically using the cable provided, following the diagram
shown in Fig. 6.
