The pump should not be connected to the electrical
system until it has been properly installed in the pipe
system.
We recommend that installation is carried out by skilled personnel
with technical qualifications required by the specific legislation in
force.
The term skilled personnel means persons whose training,
experience, and instruction, as well as their knowledge of the
respective standards and requirements for accident prevention and
working conditions, have been approved by the person in charge of
plant safety, authorizing them to perform all the necessary activities
during which they are able to recognize and avoid all dangers.
5.1 Mounting the product
• Secure the pump to a solid foundation by bolts through the
holes in the flange or the base plate.

5.4 Outdoor installation
When installed outdoors, the motor must be provided with a suitable
cover to avoid condensation on the electronic components.
When fitting a cover to the motor, observe the guidelines
in section Motor cooling.
The cover must be sufficiently large to ensure that the motor is not
exposed to direct sunlight, rain, or snow. Grundfos does not supply
covers. Therefore, we recommend that you have a cover built for
the specific application. In areas with high air humidity, we
recommend enabling the built-in standstill heating function.

Examples of covers (not supplied by Grundfos)
5.5 Drain holes
When the motor is installed in moist surroundings or areas with high
air humidity, the bottom drain hole should be open.
The enclosure class of the motor will then become lower. The open
drain hole helps to prevent condensation in the motor as it will make
the motor self-vent and allow water and humid air to escape.
The motor has a plugged drain hole on the drive side. The flange
can be turned 90 ° to both sides or 180 °.
