5. Verify that the brine 3-way valve is in the normal operations position with its handle is pointing to the
open pathway.
6. Verify that the Pressure Regulating valve is completely open by turning the valve until it stops
counterclockwise .

: Y
OU NEVER WANT TO START THE HIGH PRESSURE PUMP WITHOUT THE PRESSURE
REGULATING VALVE BEING IN THE FULLY OPEN POSITION
,
TURNED TO THE STOP IN THE
FULL COUNTERCLOCKWISE
.
7. Turn on the Boost Pump and monitor the system until the boost pump has re-primed the system and water
is flowing
out of the brine discharge.
8. Turn on the high pressure pump for approximately 30-40 seconds to allow the chemical reagent to
dissolve and be pulled into the RO pressure vessels.
9. Turn off the high pressure pump
10. Turn off the boost pump
11. Turn the Inlet Water Selector 3-way valve to the middle off position and allow the membrane to sit in the
cleaning solution for a time ranging from 2 hours to overnight .
After the cleaning solution has been allowed to remain in contact with the membrane for the desired length
of time, the standard “
Freshwater Flush Procedure
” is used to rinse out the cleaning chemical. The
procedure is outlined below.

12. Remove the spent cleaning cartridge from the 5 micron pre-filter housing and replace it with a new 5
micron filter element or if necessary, proceed to inserting an organics cleaning cartridge
13. Verify that the Product Water Selector 3-way valve is in the “ Water sample
” position.
14. Turn the Inlet Water Selector 3-way valve from the middle “ Off
” position to the freshwater flush position
(you will be pulling water from your ships freshwater tanks, so be sure there is adequate fresh water in the
tank for the freshwater flush or you run the risk of running the system dry).
15. Verify that the Pressure Regulating valve is completely open by turning the valve until it stops
counterclockwise . (you never want to start the high pressure pump without the pressure regulating valve
being in the fully open position, turned to the stop counterclockwise)
16. Turn on the boost pump and let it run for at least 1 minute (verify freshwater flow by seeing water exiting
the brine discharge).
17. After confirming water flow exiting the brine, turn on the high pressure pump for 5 minutes.
