Servicing the pump involves removing the pump assembly, accessing the 
orifice, and replacing the pump. 

Use the following procedure to remove the pump assembly. 

1.

 

Disconnect the 8 pin connector from the pump board (

Figure 7–17

). 

2.

 

Using the correct wrenches, remove the hex elbow attached to the valve 
assembly (

Figure 7–17

). 

3.

 

Remove the Tygon tubing from the barb fitting on the sample inlet 
assembly (

Figure 7–17

).
