5. Installation
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 pump must be secured to a solid foundation by bolts through
the holes in the flange or the base plate.
5.2 Cable entries
The motor has four M20 screwed cable entries fitted with blind
plugs from factory.
The following cable glands are included:
• 2 x M20 cable gland, cable diameter ∅5 mm
• 1 x M20 cable gland, cable diameter ∅7-14 mm.

fixed objects
5.4 Outdoor installation
When installed outdoors, the motor must be provided with a
suitable cover to avoid condensation on the electronic
components. See fig. 2.
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. We therefore recommend that you have a cover
built for the specific application. In areas with high air humidity,
we recommend that you enable the built-in standstill heating
function.

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 be lower. The open
drain hole helps prevent condensation in the motor as it will make
the motor self-venting 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 °.

Warning
Installation and operation must comply with local
regulations and accepted codes of good practice.
Warning
All electrical work should be performed by a
qualified electrician in accordance with the latest
edition of the National Electrical Code, local
codes and regulations.
Warning
Verify that the electrical supply has been
switched OFF before making any connections.
The pump should not be connected to the
electrical system until it has been properly
installed in the piping system.
Note
Note
In order to ensure sufficient cooling of the motor,
the distance (D) between the end of the fan cover
and a wall or other fixed objects must always be
at least 2 inches (50 mm), irrespective of motor
size. See fig. 1.
