(2)
The SYSTEM OPERATION PRESSURE gauge (figure 21, item 13) indicates less than 900 PSI (62.1 bar).
(3)
The PRODUCT WATER OUTPUT PRESSURE gauge (figure 21, item 16) indicates less than 20 PSI(1.4 bar).
(4)
The BRINE DISCHARGE PRESSURE gauge (figure 21, item 15) indicates approximately 10 PSI (0.7 bar).
(5)
The BRINE flow meter (figure 21, item 12) indicates approximately 3.2 gallons (12.1 liters) per minute.
(6)
The PRODUCT WATER flow meter (figure 21, item 17) indicates approximately 66 gallons (248.8 liters) per
hour.
b.
At the ROWPU 1 system controller (figure 21, item 14), verify that the SALINITY METER (figure 25, item 6)
indicates that product water salinity is less than 500 parts per million (ppm), as indicated by five or fewer LEDs
lit.
ROWPU 2 STARTUP
! CAUTION
If bypassing the media filter, RO-PG-2-1, 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-2-1 (figure 21, item 4), ROWPU 2 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.
Complete the following actions at ROWPU 2 flow control panel (figure 21, item 18):
a.
Verify that the HIGH PRESSURE PUMP INLET pressure gauge (figure 21, 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 membranes.
b.
Fully OPEN the SYSTEM HIGH PRESSURE REGULATOR valve, RO-V-2-3 (figure 21, item 20).
c.
Observe the BRINE flow meter (figure 21, 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 21, item 22) does not rise above 50 PSI
(3.4 bar).
4.
At the ROWPU 2 system controller (figure 21, item 23), perform the following:
a.
Press the STOP pushbutton (figure 25, item 1) and verify that the SYSTEM OFF indicator (figure 13, item 2) is
illuminated.
