Figure 2-61. R. O. Pressure And Product Water Flow Gages
Slowly adjust REGULATE PRODUCT FLOW valve (3) to the right. Watch for an increase in
PRODUCT WATER FLOW gage (2), a decreased flow in BRINE FLOW gage (4), and increased pressure in the
R.O. PRESSURE PSI gage (5).
PRODUCT WATER FLOW should not exceed 12 gpm for seawater conditions,
16 gpm for fresh or brackish water. R.O. PRESSURE PSI gage should not
exceed 960 psi (seawater), 500 (fresh or brackish water). If gage readings
exceed these limits, refer to Section II, Chapter 3, Troubleshooting.

Close REGULATE PRODUCT FLOW valve very slowly. Watch gages until you obtain proper
balance shown in Table 2-4.
