3. Installing the product
3.1 Safety information and preparation
The pump operates completely submerged in the
liquid and does not require any additional protection.
In addition to the pump, the following items are
required:
•
A cable suspension system for securing the
cables and regulating the height of the level
sensors.
•
Control equipment, for example MP 204.
•
KPL and KWM: A column pipe with a seat ring
and integrated anti-rotation brackets on which the
pump is standing. The seat ring can be supplied
with the pump as an installation accessory.
Please contact Grundfos for details.
•
KPG: A gate with a flange connection that
corresponds to the outlet flange of the KPG.
A blue or grey circle with a white graphical
symbol indicates that an action must be
taken.
A red or grey circle with a diagonal bar,
possibly with a black graphical symbol,
indicates that an action must not be taken
or must be stopped.
If these instructions are not observed, it
may result in malfunction or damage to the
equipment.
Tips and advice that make the work easier.
If the pump is not going to be installed
immediately, the free end of the power
cables or the sensor cables must be
protected from moisture which could
otherwise enter the motor windings. This
must be done as soon as the pump is
received.
Protection can be carried out by fitting a
cable cap or by wrapping the free end of
the cables in plastic and taping over the
plastic with strong waterproof tape.
If the pump system is configured for side
discharge, locate the pump and column
pipe cover so that the cable inlet is
opposite of the water outlet.
- Pump installation in pits must be carried
out by specially trained persons.
- Work in or near pits must be carried out
according to local regulations.
- For safety reasons, all work in pits must
be supervised by a person outside the
pit.
