14.1  Drive belt replacement (disassembly and assembly)  

 
This section has the instructions for the drive belt replacement:  
 

14.1.1 Disassembly 

 

1.  If the DFRA equipment is operating, it must be stopped.  To do this, set selector 

I2 to zero (stop) and wait five minutes until the two fans stop completely.  Then 
set the switch I1 to position “0” to turn off the power supply. See figure 1. 

    
 
 

 

 

Figure 1: Front/top view of base unit module  

 
 
 
 

2.  Next, remove the front cover (5) of the base unit.  To do this, remove the screws 

(3) that connect the front cover to the base unit.  Use the handles (4) to remove 
the front cover.
