ROWPU 1 STARTUP
! CAUTION
If bypassing the media filter, RO-PG-1-1, 20-micron filter outlet/5-micron filter inlet pres-
sure should not exceed 45 PSI (3.1 bar), or damage could occur.
1. OPEN the following valves:
a. RO-V-1-1 (figure 9, item 3), ROWPU 1 inlet sea water supply.
b. RO-V-1 (figure 8, item 1), main sea water supply.
2. Slowly OPEN RO-V-2 (figure 8, item 2), media filter supply.
3. At ROWPU 1 flow control panel (figure 9, item 9), perform the following:
a. Verify that the HIGH PRESSURE PUMP INLET pressure gauge (figure 9, 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 mem-
branes.
b. Fully OPEN the SYSTEM HIGH PRESSURE REGULATOR valve, RO-V-1-3 (figure 9, item 11).
c.
Observe the BRINE flow meter (figure 9, 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 9, item 13) does not rise above
50 PSI (3.4 bar).
4. At the ROWPU 1 system controller (figure 9, item 14), perform the following:
a. Press the STOP pushbutton (figure 13, item 1), and verify that the SYSTEM OFF indicator (figure 13,
item 2) is illuminated.
b. Press the START pushbutton (figure 13, item 3), and verify the following:
(1)
BOOSTER PUMP indicator (figure 13, item 4) illuminates.
(2)
SYSTEM ON indicator (figure 13, item 5) is illuminated.
5. Verify the following conditions at the ROWPU 1 flow control panel (figure 9, item 9):
a. The BRINE flow meter (figure 9, item 12) displays a minimum flow reading of 4 gallons (15.1 liters) per
minute with no bubbles present.
b. The BRINE DISCHARGE PRESSURE gauge (figure 9, item 15) indicates less than 15 PSI (1 bar).
c.
The PRODUCT WATER OUTPUT PRESSURE gauge (figure 9, item 16) indicates approximately
0 PSI (0.0 bar).
