Checking the direction of rotation
notE
• The description below applies to three-phase
motors only.
The motor fan cover has an installation indicator. See
fig. 1. Based on the motor cooling air, it indicates the
direction of rotation of the motor.
Before the motor is started for the first time or if
the position of the indicator has been changed, the
indicator function should be checked, for instance by
moving the indicator field with a finger.
To determine whether the direction of rotation is
correct or wrong, compare the indication with the table
below.

You can place the indicator in various positions on the
motor, but do not place it between the cooling fins close
to the screws that hold the fan cover.
The correct direction of rotation is also shown by
arrows on the motor fan cover.
Maintenance
WaRnInG
• Before starting work on the pump, switch off the
power supply. Make sure that the power supply
cannot be accidentally switched on.
• Make sure that the escaping water does not cause
injury to persons or damage to the equipment.
The internal pump parts are maintenance-free. You
must keep the motor clean in order to ensure adequate
cooling of the motor. If the pump is installed in dusty
environments, clean and check the pump regularly.
Take the enclosure class of the motor into account when
cleaning.
The motor has maintenance-free, greased-for-life
bearings.
