u.
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).
CAUTION
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.
