4. Configure the system for a Once Through Rinse.
5. Fully open the Back Pressure Regulating Valve [17] counter clockwise.
6. Press the “Start” switch. The fresh water rinses the system and discharges out to waste [18].
7. Apply 200 psi of pressure to the system by turning the Back Pressure Regulator [17] clockwise. This allows the
system to produce a minimal amount of product water, which ensures that the product water line remains wet.
8. Just prior to depleting the rinse water from the bucket, fully open the Back Pressure Regulator Valve [17] counter
clockwise and stop the system (press stop button twice to abort Fresh Water Flush Cycle).
9. Fully open the Back Pressure Regulating Valve [17] counter clockwise.
10. Fill the 5-gallon bucket with product water. Add 4 ounces (1/6th bottle) of SRC SC Storage Chemical to the
water in the plastic bucket. DO NOT ADD ANY OTHER CHEMICAL.
11. Mix and thoroughly dissolve the solution in the container.
12. If the system will be exposed to freezing temperatures, add 1 gallon (4 liters) food grade glycerin (propylene
glycol) to the 5 gallons of Storage Solution. This prevents the water in the system from freezing. DO NOT ADD
ANY OTHER CHEMICAL.
13. Configure the system for a Closed Loop Configuration .
14. Operate the system by pressing the "Start" Switch. The Storage Chemical Solution flows from the container
through the system and back into the container in a Closed Loop configuration. Do not pressurize the system;
leave the Back Pressure Regulator [17] fully open.
15. After approximately 10 minutes of circulation, stop the system (Press stop button twice to abort Fresh Water
Flush Cycle).
16. Configure the system for a Once Through Rinse .
17. Start the system, which discharges the Storage Chemical Mixture through the Brine Discharge Thru Hull Fitting
[18].
18. Stop the system just before depleting the Storage Chemical Solution from the tank. Press the Stop switch twice
to abort the Automatic Fresh Water Flush cycle.
19. Reconfigure the system for normal operation by reconnecting the Sea Strainer [3] outlet line for normal operation.
Or if the system is equipped with a Inlet Clean/Rinse 3-way ball valve [30] then position this valve to the normal
operating position towards the Sea Strainer.
20. WINTERIZING AND FREEZING TEMPERATURE STORAGE NOTE: If the system is exposed to freezing
temperatures, remove product water from the Post Filtration Section.
a) Open the Charcoal Filter Bowl and drain the product water from it.
b) Disconnect the bottom tube fitting from the Ultra Violet Sterilizer and drain the product water from it.
c) Open the pH Neutralizer Filter Bowl and drain the product water from it.
d) Disconnect or Close the valve from the fresh water tank to the Automatic Fresh Water Flush and drain the
Fresh Water Flush Charcoal Filter bowl.
The system may now be left unattended for up to 3 to 6 months. With ideal conditions including a relatively new
R.O. Membrane Element, a clean system prior to storage, cool temperatures, and no leakage of storage chemical
within the system, it provides protection for up to 6 months. Adverse conditions may provide less protection.
Evaluate these factors before determining the proper interval between repeated rinsing and storage periods.
R.O. Membrane Element Cleaning Procedures
Do not arbitrarily clean the R.O. Membrane in a NEW system. If a New system experiences low production or high
salinity then it should be operated for up to 48 hours continuously to clear and saturate the R.O. Membrane Element
and product water channel. If a new system still experiences low production and or high salinity after 48 hours of
continual operation, then contact the factory.
The membrane element requires cleaning from time to time. Biological growth and salt accumulation eventually
make replacement necessary. The frequency of required cleaning depends on the amount of production loss and
salt rejection loss resulting from normal use. In order to properly assess performance changes, it is important to
maintain daily log readings for comparison.
During performance comparisons, Feed Water Temp, Feed Water Salinity, and System Operating Pressure must
be taken into consideration and compensated for. After compensations, a 10% decline in productivity (GPH Flow)
and/or a 10% increase in salt passage indicate that the R.O. Membrane Element may requires cleaning.
