The following notes and recommendations refer to
Figure 26 on page 286, Figure 27
ure 28 on page 288, and
A. Distance between the clamps that secure the
drop cable to the delivery pipe.
B. Distance from the bottom of the well to the elec-
tric pump.
Recommendations:
• Non-return valve at 10 m distance from the deliv-
ery flange, plus an additional non-return valve
every 30-50 m of piping.
• Secure the drop cable to the pipe every 2 to 3
metres of piping.
• Make sure the electric pump is installed at a safe
distance from the bottom of the well.
• Make sure there is a minimum distance of 3 mm
between the diameter of the pump and the inter-
nal diameter of the well.
• During operation, make sure that the water circu-
lation speed around the motor is at least 8 cm/
sec.
• Make sure that the minimum dynamic level of the
water in the well is at least 1 m above the pump's
delivery flange.

4.4 Electrical installation

Precautions
WARNING:
• Make sure that all connections are
performed by qualified installation
technicians and in compliance with
the regulations in force.
• Before starting work on the unit,
make sure that the unit and the con-
trol panel are isolated from the power
supply and cannot be energized.
NOTICE:
According to the installation, for the Resiboost with
A1 class (EMC), the installer will have to assess
whether additional measures are necessary to miti-
gate possible radio interference.
