3.3 Application range
The iSave should only be used within the
following limits:
1)
Continuous torque above max. differential pressure will harm the iSave
2)
Pressure can reach this pressure level at start-up and permeate flush.
3)
Intermittent pressure is acceptable for less than 10 minutes within a period of 6 hours.
4)
Typical average flow at 60 barg
5)
Dependent on NaCI concentration
6)
