O (water)). Drying
the system using sterile nitrogen or air flow may cause static dis-
charge that can damage valve control mechanisms, especially on
systems with polypropylene tubing.
If the system is dried, the valve bodies should be grounded before
nitrogen or air flow is applied. Contact your GE Healthcare repre-
sentative regarding purchase and installation of grounding kits.
NOTICE
Fit protective caps on all electrical and optical connectors when
not in use.
NOTICE
When ÄKTAprocess is filled with a storage solution, the temperature
must be high enough to prevent freezing, and low enough to
prevent evaporation.

The table below describes the procedure for short term storage. This procedure is appli-
cable for storage durations of up to one month.
