4. Mechanical installation

4.1 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 +104 °F
(+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
through the pump. The liquid
1
flow direction can be horizontal
or vertical, depending on the
control box position.
Close the isolating valves and
make sure that the system is not
2
pressurized 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.
