1.3 Notes
The symbols and notes below may appear in
Grundfos installation and operating instructions,
safety instructions and service instructions.
2. Installing the product
2.1 Pump location
Install the pump in a dry well-ventilated location.
Protect the pump from rain, frost and direct sunlight.
We recommend that you place the pump as close as
possible to the liquid to be pumped.
2.2 Mechanical installation
2.2.1 Foundation
Fasten the pump to a solid horizontal foundation by
means of screws through the holes in the base plate.
NS pumps can be installed in horizontal or vertical
position. If the pump is installed in vertical position,
the motor must be above the pump.
PF pumps must only be installed in horizontal
position.
2.2.2 Pipework
Make sure that the pump is not stressed by the
pipework.
Fit rigid pipes with pipe hangers.
Use sealing tape on the inlet and outlet ports of the
pump.
2.3 Electrical connection
Observe these instructions for explosion-
proof products.
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.
Observe local regulations concerning
limits for manual lifting or handling.
CAUTION
Crushing of feet
Minor or moderate personal injury
- Use safety shoes when handling the
pump.
DANGER
Electric shock
Death or serious personal injury
- Before starting any work on the product,
make sure that the power supply has
been switched off and that it cannot be
accidentally switched on.
DANGER
Electric shock
Death or serious personal injury
- The protective earth of the socket outlet
must be connected to the protective
earth of the pump. The plug must
therefore have the same PE connection
system as that of the socket outlet. If
not, use a suitable adapter.
We recommend that you fit the permanent
installation with a residual-current circuit
breaker, RCCB, with a tripping current less
than 30 mA.
DANGER
Electric shock
Death or serious personal injury
- If the pump is used for cleaning or other
maintenance of swimming pools,
garden ponds or similar places, make
sure that the pump is supplied through a
residual-current circuit breaker, RCCB,
with a tripping current of 30 mA.
DANGER
Electric shock
Death or serious personal injury
- Power supply cables without a plug
must be connected to a supply
disconnecting device incorporated in
the fixed wiring according to the local
wiring rules.
DANGER
Electric shock
Death or serious personal injury
- The pump must be earthed.
