2.2.3 Positioning the product

inlet strainer must be covered by the pumped liquid
to ensure efficient cooling.

2.2.4 Connecting the outlet pipe
The outlet pipe can be connected to the pump outlet
port on the top or the side by means of an adapter.
Use the 90 ° adaptor for the side outlet port.
Fig. 7 Connecting the outlet pipe
The adapter enables connection of a pipe or hose
matching 3/4", 1" and 1 1/4" external pipe thread (G).
Cut off the adapter so that it matches the outlet pipe
diameter. If a system gasket is used between the
outlet pipe and the adapter, the cut-off adapter must
have an even and smooth surface.
The approval according to DIN EN 12056-4
stipulates that the outlet pipe from the fixed
installation must be connected directly to the pump
outlet port. If the adapter supplied with the pump is to
be used, cut off the 3/4" and 1" sockets.
