Pipe Connection; Electrical Connection - Grundfos SP Series Installation And Operating Instructions Manual

5.5.1 Maximum liquid temperature
Out of consideration for the rubber parts in pump and motor, the
liquid temperature must not exceed 40 °C (105 °F). See also the
table below.
The pump can operate at liquid temperatures between 40 °C and
60 °C (105 °F and 140 °F) provided that all rubber parts are
replaced every third year.

5.6 Pipe connection

If noise may be transmitted to the building through the pipeswork,
we recommend that you use plastic pipes.
Plastic pipes are recommended
Note We recommend plastic pipes for 4" pumps only.
When using plastic pipes, secure the pump by an unloaded
straining wire.
WARNING
Hot liquid
Death or serious personal injury
- Use pipes designed for the maximum pump
pressure plus 10 % to avoid pipe burst.
- Make sure that the plastic pipes are suitable for
the actual liquid temperature.
When connecting plastic pipes, use a compression coupling
between the pump and the first pipe section.

6. Electrical connection

DANGER
Electric shock
Death or serious personal injury
- Switch off the power supply before you start any
work on the product.
- Make sure that the power supply cannot be
accidentally switched
