6. Mechanical installation

Before installing the pump, check that the pump type
and parts are as ordered.
Warning
When pumping hot or cold liquids, make
sure that persons cannot accidentally
come into contact with hot or cold
surfaces.

6.1 Installation of pump

Install the pump on a plane surface using the
mounting holes in the motor base plate and a
minimum of four bolts. Tighten each of the four bolts
to a torque of 10 Nm.
Install the pump so that air locks are avoided in the
pump housing and pipework.
Figure 1 and the table below show the permissible
pump positions.
