NOTE
During fresh water flush cycles, a brine flow meter reading of less than 1 gallon (3.8
liters) per minute is an indication that the charcoal filters may be clogged. Clogged
charcoal filters can cause shortened service life of the reverse osmosis membrane
elements.
5. At each flow control panel (figure 9, items 9 and 18), verify that the BRINE flow meters (figure 9, items 12
and 21) indicate a flow rate of approximately 1 gallon (3.8 liters) per minute each during the fresh water flush
cycle.
ROWPU SYSTEM LAYUP
1. Perform the ROWPU system shutdown procedure as detailed earlier in this work package.
2. Perform the media filter backflush procedure as detailed earlier in this work package.
3. Perform the ROWPW fresh water flush procedure as detailed earlier in this work package.

a. FRESH FLUSH (figure 13, item 8) indicators blinking occasionally.
NOTE
During ROWPU system layup cycles, the SALINITY METER acts as a system clock and
counts down from seven to zero indicating the number of days remaining until the next
fresh water flush cycle.
b. Verify that the SALINITY METER (figure 13, item 6) displays number of days until next fresh water flush
