CRU: Concentrate Reusable Unit
Permeate: The treated, totally desalinated water which is produced by the RO-plant and
supplied to the reservoir tank.
Concentrate: Is the water that is led to outlet or to BWT PERMAQ Compact CRU. This wa-

Level switch: Is a switch, which gives a signal when the RO-plant must either be started or
stopped, and it stops the transport pump in case of dry-running of the tank.
