Motor connections
1, 2 and 3: wash speed (18-pole winding).
4, 5 and 6: extract speed (2-pole winding)
7 and 9: motor overload protector.
Motor overload protector
The motor is equipped with two self-resetting,
thermal overload protectors, situated one in each
of the windings of the stator. The protectors are
connected in series and will trip at a temperature
of 120
°
C (248
°
F) (3-phase) or 130
°
C (266
°
F)
(single phase). In the event the protectors fail
but the motor remains otherwise undamaged, an
overload protector may be mounted in the control
unit of the machine. Before making such installa-
tion check to ascertain that the windings are not
damaged. A burned out motor can be re-wound.
NOTE
Before connecting a separate overload
protector consult the local code.
Single-phase W125 and W185 machines are
also equipped with a manually resettable
overload protector mounted on the extract relay
in the control unit. This overload protector
protects the motor during the start-up of the
extraction.
Removing the motor
• Remove the drain valve (1) from the long shaft
by pulling it straight up.
• Remove the tensioning unit (2) on the rear of
the motor.
• Disconnect the connector (3) placed
diagonally under the rear edge of the motor.
• Remove the two screws (4). Pull the shaft
forward slightly until the guide pins pull out of
the shaft brackets. Remove the motor unit.
