uids not compatible with the pump construction ma-
terial.
An improper use of the product leads to the loss of
the warranty.
3.2 Application limits
For the maximum working pressure and the liquid
temperature intervals, see
3.3 The data plate
The data plate is a label on the pump. The data
plate lists key product specifications. For more infor-
mation, see Figure 1 on page 183.
WRAS label - Installation Requirements and
Notes (for UK market only)
A WRAS label on the pump means it is a Water
Regulations Advisory Scheme approved product.
This product is suited to be used with potable water
for human consumption. For more information, refer
to IRNs R001 and R415 in the WRAS Water Fittings
and Materials Directory (www.wras.co.uk).
IMQ or other marks (for electric pump only)
Unless otherwise specified, for products with a mark
of electrical-related safety approval, the approval re-
fers exclusively to the electrical pump.
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 Facility requirements

4.1.1 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 no obstructions hinder the normal
flow of the cooling air that is delivered by the mo-
tor fan.
• 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.
• The ambient temperature must be between
-30°C (-22°F) and +50°C (+122°F) unless other-
wise specified in the data plate.
• The relative humidity of the ambient air must be
less than 50% at +40°C (+104°F).
Table 3 on page 186
Installation above liquid source (suction lift)
The theoretical maximum suction height of any
pump is 10.33 m. In practice, the following affect the
suction capacity of the pump:
• Temperature of the liquid
• Elevation above the sea level (in an open sys-
tem)
• System pressure (in a closed system)
• Resistance of the pipes
• Own intrinsic flow resistance of the pump
• Height differences
For more information about the performance, see .
NOTICE:
Do not exceed the pumps suction capacity as this
could cause cavitation and damage the pump.

4.1.2 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.
Piping checklist
• Pipes and valves must be correctly sized.
• Pipe work must not transmit any load or torque to
pump flanges.
For illustration that shows the piping requirements,
see Figure 5 on page 188.

4.2 Electrical requirements

• The local regulations in force overrule these
specified requirements. In the case of fire fighting
systems (hydrants and/or sprinklers), check the
local regulations in force.
Electrical connection checklist
Check that the following requirements are met:
• The electrical leads are protected from high tem-
perature, vibrations, and collisions.
• The power supply line is provided with:
– A short-circuit protection device
– A high-sensitivity differential switch (30 mA)
[residual current device RCD] to provide more
protection against electric shock.
– A mains isolator switch with a contact gap of
at least 3 mm
The electrical control panel checklist
NOTICE:
The control panel must match the ratings of the elec-
tric pump. Improper combinations could fail to guar-
antee the protection of the motor.
Check that the following requirements are met:
• The control panel must protect the motor against
overload and short-circuit.
• Install the correct overload protection (thermal re-
lay or motor protector).
