4.1 Installing the pump
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).
