are aligned.
Use genuine spare parts only!
Follow these instructions to change the contact pulley and springs:
Disconnect the cooler from the power supply.
„
Unscrew the nut of the pump head (wrench size 5.5).
„
Remove the pump head from the motor shaft. Now the driver can be removed
„
from the pump head and is ready for maintenance.
The removal of the springs (4 pcs.) away from the driver is possible without any

tools. Therefore press together the spring and pull it out of the groove in the
driver, respectively out of the boring of the roll shaft. Now the roll shaft can be
dismounted and the contact pulleys can be replaced.
Assemble the pump in reversed order.
