TM055236
Minimum distance, D, from the motor to a wall or
other fixed objects
8.9 Outdoor installation
If you install the motor outdoors, provide the motor
with a cover and open the drain holes to avoid
condensation on the electronic components. See
figure Examples of covers, not supplied by Grundfos.
When fitting a cover to the motor, observe
the guidelines in section Ensuring 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. We therefore
recommend that you have a cover built for the
specific application. In areas with high humidity, we
recommend that you connect the motor permanently
to the mains supply and activate the built-in standstill
heating function. See section Standstill heating.

Examples of covers, not supplied by Grundfos
In order to maintain the UL mark,
additional requirements apply to the
equipment. See section Installation in the
USA and Canada.
