d. The SYSTEM OPERATION PRESSURE gauge (figure 9, item 13) indicates less than 50 PSI (3.4 bar).
e. The PRODUCT WATER flow meter (figure 9, item 17) indicates less than 1 gallon (3.8 liters) per hour.
6. Allow the system to operate in this configuration for approximately two minutes. Ensure that all gauges
stabilize, and most of the air is purged from the system as indicated by a fluid stream with few or no bubbles
flowing through the BRINE flow meter (figure 9, item 12).
! CAUTION
Increase system pressure slowly. Failure to comply with this caution will cause damage
to the reverse osmosis membranes.
7. At ROWPU 1 flow control panel (figure 9, item 9), slowly increase system pressure by rotating the SYSTEM
HIGH PRESSURE REGULATOR valve, RO-V-1-3 (figure 9, item 11) in the INCREASE direction until the
SYSTEM OPERATION PRESSURE gauge (figure 9, item 13) indicates 400 PSI (27.6 bar).
8. Allow the system to operate in this configuration for approximately two minutes. Ensure that all gauges
stabilize and that most of the air is purged from the system as indicated by fluid streams with few or no
bubbles flowing through the BRINE flow meter (figure 9, item 12) and the PRODUCT WATER flow meter
(figure 9, item 17).
