ROWPU 2 STARTUP
! CAUTION
If bypassing the media filter, RO-PG-2-1, 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-2-1 (figure 9, item 4), ROWPU 2 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. Complete the following actions at ROWPU 2 flow control panel (figure 9, item 18):
a. Verify that the HIGH PRESSURE PUMP INLET pressure gauge (figure 9, item 19) 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-2-3 (figure 9, item 20).
c.
Observe the BRINE flow meter (figure 9, item 21) 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 22) does not rise above
50 PSI (3.4 bar).
4. At the ROWPU 2 system controller (figure 9, item 23), 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. At the ROWPU 2 flow control panel (figure 9, item 18), verify the following:
a. The BRINE flow meter (figure 9, item 21) displays a flow reading of 4 gallons (15.1 liters) per minute with
no bubbles present.
b. The BRINE DISCHARGE PRESSURE gauge (figure 9, item 24) indicates less than 15 PSI (1 bar).
c.
The PRODUCT WATER OUTPUT PRESSURE gauge (figure 9, item 25) indicates approximately
0 PSI (0.0 bar).
