7.2 System backpressure test failure
Description
The System backpressure test tests that the backpressure in the system does not exceed
a specified value. Increased backpressure may result from an obstruction in the flow
path such as kinked tubing.
Corrective action
If the System backpressure test fails, make sure that tubing is not kinked or obstructed.
Replace any kinked tubing.
Locate the source of increased backpressure by moving the outlet tubing to the outlet
port of successive modules, starting with the outlet valve(s) and working systematically
towards the beginning of the flow path. The backpressure will drop when the blocked
module is excluded from the flow path.
If the cause of the failure cannot be located, contact your GE service organization.
