7. Mechanical installation

7.1 Location

The pump is suitable for indoor and outdoor
installation. It is resistant to sunlight.
For outdoor installation, the pump
must be fitted with a protective
Note
cover (accessory). See section
7.5 Protective cover and
13. Accessories.
Should the unlikely event of an
internal leakage occur, pumped
liquid will be drained out from the
base and/or end cover instead of
Note
damaging the pump. Install the
pump in such a way that no unde-
sirable collateral damage can
arise.

7.2 Foundation

Mount the pump on the base plate with hori-
zontal suction port and vertical discharge port.
The pump must be installed horizontally.
The maximum permissible inclination angle is
± 18 °. See fig. 2.

pump
Being self-cooling, the pump requires no
space or ventilation at the sides.
Ensure that the maximum ambient
temperatures do not exceed the
Note
values stated in section
6. Operating conditions.

7.4 Pipework

Never use unnecessary force
Note
when connecting the pipes.
The pump is supplied with 1" NPT screwed
connections. Fit the connections in the suction
