3.1 Lifting the pump
Always lift directly on the pump head or the cooling fins when
handling the pump. See fig. 8.
For large pumps, it may be ncessary to use lifting equipment.
Position the lifting straps as illustrated in fig. 8.

3.2 Installing the pump
The MAGNA1 is designed for indoor installation.
The MAGNA1 pump range includes both flanged and threaded
versions. These installation and operating instructions apply to
both versions, but give a general description of flanged versions.
If the versions differ, the threaded version will be described
separately.
The pump must be installed in such a way that it is not stressed
by the pipework. The maximum permissible forces and moments
from pipe connections acting on the pump flanges or threaded
connections can be found on page 34.
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 (pump housing with M12 thread).
To ensure adequate cooling of motor and electronics, observe the
following requirements:
• Position the pump in such a way that sufficient cooling is
ensured.
• The ambient temperature must not exceed +40 °C.
Warning
Observe local regulations setting limits for
manual lifting or handling.
