3.1 Installing the pump
The MAGNA3 is designed for indoor installation.
The pump must be installed in such a way that it is not stressed
by the pipework.
The pump may be suspended direct in the pipes, provided that
the pipework can support the pump.
Twin-head pumps are prepared for installation on a mounting
bracket or base plate.
To ensure adequate cooling of motor and electronics, the
following must be observed:
•
Position the pump in such a way that sufficient cooling is
ensured.
•
The temperature of the ambient air must not exceed +40 °C.
Warning
Observe local regulations setting limits for
manual lifting or handling.
Step
Action
Arrows on the pump housing
indicate the liquid flow direction

or vertical, depending on the
control box position.
Close the isolating valves and
make sure that the system is not
2
pressurised during the
installation of the pump.
Mount the pump with gaskets in
3
the pipework.
Fit bolts and nuts. Use the right
4
size of bolts according to system
pressure.
