Adjusting the RO System Flow Rates
1. Be sure the pre - treatment systems have been flushed and put in service. If anti - scalant is being used,
be sure to confirm the dose and mix of the solution with the sales rep before starting the system.
2. If possible remove the prefilter and fill it with water. This will remove the majority of the air in the system.
3. Make sure the water supply is turned on and that you have a minimum of 30 PSI pressure to the system.
The optimal pressure would be 60 PSI.
NOTE: SYSTEM RUNNING PRESSURE CANNOT FALL BELOW 30 PSI.
4. Open the concentrate valve completely by turning it counterclockwise. Close the concentrate recycle
valve (if applicable) completely by turning it clockwise.
5. Turn RO system to the AUTO position.
6. Let the system run for 5 - 10 minutes to flush the remaining air out of the filters and membranes.
NOTE: The system may need to be shut off and turned back on several times to flush the air out
and for the system to continue to run. This may be increased if the sediment filter is not
filled with water first.
4. Check the running inlet pressure. The pressure should be between 40 - 60 PSI ( 30 PSI minimum ) dur-
ing operation to ensure the system will not shut down due to a low pressure fault.
5. Adjust the system to the designed flow rates without exceeding 150 PSI on the pump/membrane pres-
sure gauge. This adjustment is system and site specific. The concentrate valve, the concentrate recy-
cle valve and the throttle valve on the pump will need to be balanced so the RO meets the designed flow
rates for each stream without exceeding 150 PSI on the System Pressure gauge.
RO Start - up
WARNING: NEVER EXCEED THE MAXIMUM PRESSURE RATING OF YOUR SYSTEM.
Adjust the pump throttle valve and concentrate valve until the correct flow is achieved. For example,
DEFENDER - 4000 should be adjusted until it produces about 4000 GPD or 2.78 GPM of permeate
(product water) at 77˚F. The designed flow may be achieved below 150 PSI but it is IMPORTANT not to
exceed 150 PSI on the System Pressure when adjusting.
