4 Installation

Precautions
WARNING:
• Observe accident prevention regula-
tions in force.
• Use suitable equipment and protec-
tion.
• Always refer to the local and/or na-
tional regulations, legislation, and co-
des in force regarding the selection of
the installation site, plumbing, and
power connections.
4.1 Pump handling
WARNING:
Observe local regulations setting the lim-
its for manual lifting or handling.
Always lift the pump by the pump head or pump
housing. If the pump weight exceeds the manual
handling limits, use lifting equipment, positioning lift-
ing straps according to Figure 11
4.2 Facility requirements
4.2.1 Pump location
DANGER:
Do not use this unit in environments that
may contain flammable/explosive or
chemically aggressive gases or powders.
Guidelines
Observe the following guidelines regarding the loca-
tion of the product:
• Make sure that the installation area is protected
from any fluid leaks, or flooding.
• If possible, place the pump slightly higher than
the floor level.
• Provide shut-off valves in front of and behind the
pump.
• The relative humidity of the ambient air must be
less than 95%.
4.2.2 Minimum inlet pressure at the
suction port
The values in the table are the inlet pressure above
the atmospheric pressure.

NOTICE:
• Do not apply a pressure lower than the values
specified as this could cause cavitation and dam-
age the pump.
• The inlet pressure plus the pump pressure
against a closed valve must be lower than maxi-
mum admissible system pressure.
4.2.3 Piping requirements
Precautions
CAUTION:
• Use pipes suited to the maximum
working pressure of the pump. Fail-
ure to do so can cause the system to
rupture, with the risk of injury.
• Make sure that all connections are
performed by qualified installation
technicians and in compliance with
the regulations in force.
• Do not use the on-off valve on the
discharge side in the closed position
for more than a few seconds. If the
pump must operate with the dis-
charge side closed for more than a
few seconds, a bypass circuit must
be installed to prevent overheating of
the water inside the pump.
Piping checklist
• Pipes and valves must be correctly sized.
• Pipe work must not transmit any load or torque to
pump flanges.
4.3 Electrical requirements
• The local regulations in force overrule specified
requirements listed below.
Electrical connection checklist
Check that the following requirements are met:
• The electrical leads are protected from high tem-
perature, vibrations, and collisions.
• The current type and voltage of mains connec-
tion must correspond to the specifications on the
data plate on the pump.
• The power supply line is provided with:
• A high-sensitivity differential switch (30 mA)
[residual current device RCD] suitable for
earth fault currents with DC or pulsating DC
