10.13  Temperature sensor (B3) at the condenser (only in centrifuges with 

cooling) 

• 

Remove the front panel and the support sheet for electronics (A1) as described in 
chapters 10.1, 10.2, pg. 80. 

• 

Remove the upper part of the centrifuge housing as described in chapter "Removing 
the upper part of the centrifuge housing". 

• 

Pull the plug S706 on the electronics (A1), see pg. 93, chapter 11.3. 

• 

Remove the temperature sensor (pg. 78, Fig. 5, item 37) at the condenser. 

• 

To mount the temperature sensor (B3), carry out these steps in opposite order. 
The temperature sensor must be mounted on the condenser at exactly the same 
position as earlier. 

• 

After the installation a compensation of the temperature sensor (B3) must be 
performed, see pg. 55, chapter 6.14.4. 

 
 

10.14  Fan (M3) at the condenser (only in centrifuges with cooling) 

• 

Remove the front panel and the support sheet for electronics (A1) as described in 
chapters 10.1, 10.2, pg. 80. 

• 

Remove the upper part of the centrifuge housing as described in chapter "Removing 
the upper part of the centrifuge housing". 

• 

Pull the plug S904 on the electronics (A1), see pg. 93, chapter 11.3. 

• 

Unscrew the two fastening screws of the fan. 

• 

Remove the fan (pg. 78, Fig. 5, item 38). 

• 

To mount the fan (M3), carry out these steps in opposite order. 

 
 

10.15  Fan (M5) at the motor (only in centrifuges with cooling) 

• 

Remove the front panel and the support sheet for electronics (A1) as described in 
chapters 10.1, 10.2, pg. 80. 

• 

Remove the motor as described in chapter "Removing Motor (M1) / Rubber-metal 
bearings / Speed sensor (B2.1, at the bottom of the motor) / Imbalance sensor 
(B2.2)". 

• 

Pull the plug S1001 on the electronics (A1), see pg. 93, chapter 11.3. 

• 

Unscrew the two fastening screws of the fan. 

  The two fastening screws are only accessible through the centrifuge 

chamber. 

• 

Remove the fan (pg. 78, Fig. 5, item 39) through the centrifuge chamber. 

• 

To mount the fan (M5), carry out these steps in opposite order.
