4. Installation requirements
4.1 Installing the product outdoors or in
areas with high humidity
WARNING
Fire hazard
Death or serious personal injury
‐ In high humidity environments where
condensation can occur, connect the
product permanently to the mains
supply and activate the standstill
heating function.
To maintain the cURus mark, additional
requirements apply to the equipment. See
the appendix concerning installation in the
USA and Canada.
Do not expose the product to UV radiation.
To avoid condensation, the drive must be
continuously energized due to the
application of heat, with interruptions such
that cooling to the point of condensation
does not occur.
If you install the product outdoors or in areas with a
high humidity, take the following action to avoid
condensation on the electronic components.
• Provide the product with a suitable cover.
The cover must be large enough to ensure that
the product is not exposed to direct sunlight, UV
radiation, rain or snow. Grundfos does not supply
covers.
When fitting a cover to the product,
observe the instructions for adequate
cooling.

• Open the drain holes in the product.
When you open the drain hole, the
enclosure class of the motor will be
lower than standard.
• Connect the product permanently to the mains
supply. In areas with a high humidity, activate the
built-in standstill heating function.
If you install the motor in moist
surroundings or areas with a high humidity,
ensure that the bottom drain hole is open.
As a result, the motor becomes self-
venting, allowing water and humid air to
escape. When you open the drain hole,
the enclosure class of the motor will be
lower than standard.
