Action
Make sure that inlet line A1 and B1 are primed with water or buffer and the
bottles should be standing on the buffer tray. The flow shall be off, no method
or manual run running.
Loosen the pieces of tubing marked 2A and 2B in their upper position, where
they connect to the pressure monitor.
Check if there are siphoning. If the pump flow restrictors are working there
should not be any siphoning.
If there are siphoning, the pump flow restrictors must be replaced at the
next service occasion by a GE representative.
The piece of tubing marked 2A is connected to pump flow restrictor A, the
piece of tubing marked 2B is connected to pump flow restrictor B.
Check the sample pump flow restrictor in the same way, loosen the piece
of tubing marked 2S in its upper position, where it connects to the pressure
monitor.
