10. Align the media filter maintenance mode valves (figure 21, item 6) to the "RINSE" position as shown in
figure 24.
11. Slowly OPEN RO-V-2 (figure 20, item 2), media filter supply.
12. RINSE the media filter for a minimum of 5 minutes.
13. CLOSE RO-V-2 (figure 21, item 2), media filter supply.
14. To align the media filter for normal operation, CLOSE the following valves:
a.
RO-V-2 (figure 20, item 2), media filter supply
b.
RO-V-4 (figure 20, item 4), media filter bypass
c.
RO-V-10 (figure 20, item 6), media filter backflush valve
d.
RO-V-5 (figure 21, item 5), cleaning supply
15. OPEN RO-V-3 (figure 20, item 3), media filter discharge.
16. Align the media filter maintenance mode valves (figure 21, item 6) to the "NORMAL" position as shown in figure 24.
ROWPU 1 STARTUP
! CAUTION
If bypassing the media filter, RO-PG-1-1, 20-micron filter outlet/5-micron filter inlet pressure
should not exceed 45 PSI (3.1 bar), or damage could occur.
1.
OPEN the following valves:
a.
RO-V-1-1 (figure 21, item 3), ROWPU 1 inlet sea water supply
b.
RO-V-1 (figure 20, item 1), main sea water supply
2.
Slowly OPEN RO-V-2 (figure 20, item 2), media filter supply
3.
At ROWPU 1 flow control panel (figure 21, item 9), perform the following:
a.
Verify that the HIGH PRESSURE PUMP INLET pressure gauge (figure 21, item 10) indicates a minimum of
10 PSI (0.7 bar).
! CAUTION
Failure to completely OPEN the SYSTEM HIGH PRESSURE REGULATOR valve prior to
starting the high pressure pump will result in damage to the reverse osmosis membranes.
b.
Fully OPEN the SYSTEM HIGH PRESSURE REGULATOR valve, RO-V-1-3 (figure 21, item 11).
c.
Observe the BRINE flow meter (figure 21, item 12) until it displays a minimum reading of 1 gal/min (3.8 l/min)
with few or no bubbles present.
d.
Verify that the SYSTEM OPERATION PRESSURE gauge (figure 21, item 13) does not rise above 50 PSI (3.4 bar).
