Vacuum pump with diaphragm (left) removed
Changing the vacuum pump diaphragm
CAUTION
Do not run samples while performing this procedure.
NOTE
It is not necessary to remove the vacuum pump from the CSU-200
Service Unit for the diaphragm replacement. The pump has been
isolated from the CSU-200 to enhance clarity of photography.
The vacuum pump is located at the rear of the CSU-200.
1. Turn off the power switch for the CSU-200.
2. Remove the screws securing the top instrument housing to the frame,
and lift the housing from the Service Unit. Set the housing aside.
