remove the motor cover.
•
Remove the rubber packing (pg. 78, Fig. 5, item 15) between the motor cover and
the centrifuge chamber.
•
Pull out the temperature sensor (pg. 78, Fig. 5, item 36) from the centrifuge
chamber.
•
Pull the cable of the new temperature sensor through the borehole in the centrifuge
chamber and press the temperature sensor (B1) into the borehole.
•
To mount the temperature sensor (B1), carry out these steps in opposite order.
