2.3.6 Reverse Osmosis Module (RO Module)
The main part of the RO Module comprises the high-pressure pumps,
the membrane filters and the motor-driven pressure maintaining
valve. Both the high-pressure pumps (14/1 and 14/2) are switched in
parallel and pump the raw water through the membrane filter blocks
connected on the output side. The filter blocks I (14/4) and II (14/6) each
have three membrane filters (14/5) switched one after the other, which
are arranged one underneath the other in a stand. Filter block III (14/3)
is built in over the filter blocks I and II and has two membrane filters.
After switching off the system (pumps), the solenoid valves of the
main module remain open for a certain time (approx. 5 min) in order
to enable internal pressure compensation. This is indicated by the
equipment no longer running and the "Start” button not being lit.
WARNING During this delay period, the system may not be
switched off at the main switch.
