2.3 Storage guidelines

Storage location
NOTICE:
• Protect the product against humidity, dirt, heat
sources, and mechanical damage.
• The product must be stored at an ambient tem-
perature from -40°C to +60°C (-40°F to 140°F).

3 Product Description

3.1 Pump design

The pump is a multistage, non-self priming pump.
The pump can be used to pump:
• Cold water
• Warm water
Intended use
The pump is suitable for:
• Civil and industrial water distribution systems
• Irrigation (for example, agriculture and sporting
facilities)
Improper use
DANGER:
Do not use this pump to handle flam-
mable and/or explosive liquids.
WARNING:
Improper use of the pump may create
dangerous conditions and cause per-
sonal injury and damage to property.
NOTICE:
Do not use this pump to handle liquids containing
abrasive, solid, or fibrous substances, toxic or cor-
rosive liquids, potable liquids other than water, or
liquids not compatible with the pump construction
material.
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 in-
formation, see Figure 1 .
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 wa-
ter for human consumption. For more information,
refer to IRNs R001 and R420 in the WRAS Water
Fittings and Materials Directory (www.wras.co.uk).

mark of electrical-related safety approval, the ap-
proval refers exclusively to the electrical pump.
4 Installation
Precautions
WARNING:
• Observe accident prevention regu-
lations in force.
• Use suitable equipment and protec-
tion.
• Always refer to the local and/or na-
tional regulations, legislation, and
codes in force regarding the selec-
tion of the installation site, plumb-
ing, 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 pow-
ders.
Guidelines
Observe the following guidelines regarding the lo-
cation of the product:
• Make sure that no obstructions hinder the nor-
mal flow of the cooling air that is delivered by
the motor 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).
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
Figure 4 .
NOTICE:
Do not exceed the pumps suction capacity as this
could cause cavitation and damage the pump.
