Grundfos CRE Series User Manual

5.1.1.2 Drain holes
The motor has a plugged drain hole on the drive side.
The drain hole is placed in the flange on the drive
side. You can turn the flange 90° to both sides or
180°.
With the drain hole open, 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.
