MAINTENANCE

LONG TERM STORAGE / PRESERVATION PROCEDURE
During periods when the RO unit is to be shut down for an extended period of time, it is necessary to re-
flush the unit every three weeks OR to circulate a preservative solution through the membrane to
prevent the growth of biological organisms. Use the following procedure to preserve the RO elements:
NOTE:
You should allow your unit’s product water to run to drain for the first 10 minutes after cleaning
or upon startup after preservation. Use the MODE button (see figures 3.2 and 3.4) to light the
DUMP lamp and divert product to drain.

STEPS FOR PRESERVATION CHEMICAL #3
Step 1:
Freshwater Flush the watermaker so it is filled
with fresh water
,
NOT
seawater. To flush the
Pure
Water
, refer to instructions in
Section 5.1: TO FLUSH THE PURE WATER UNIT
.
Step 2:
Dissolve the appropriate amount of Cleaning Chemical #3 (see Table 5.2) in one gallon of freshwater.
Verify the chemical is completely dissolved (use warm water if necessary).
PRESERVATIVE CHEMICAL #3 IS A FOOD GRADE PRESERVATIVE. SEE WARNING LABEL ON
SIDE OF PACKAGE AND ADHERE TO ALL SAFETY PRECAUTIONS ON LABEL.
Step 3:
Verify that the (black) High Pressure Bypass Valve is in the
CLEANING
open position.
Step 4:
Place the (gray) cleaning valve in the
CLEANING
position.
Step 5:
Remove one of the prefilter housing lids and pour in the preservative solution prepared in Step #3.
Step 6:
Start the Low Pressure Boost Pump by pressing the
LP PUMP
pushbutton located on the Master
Control Center (or on the Remote Control Center). Refer to Figures 3.2 and 3.4.
Step 7:
Start the High Pressure Pump by pressing the
HP PUMP
pushbutton located on the Master Control
Center panel (or on the Remote Control Center). Refer to Figures 3.2 and 3.4. Verify the Vacuum
Pressure Gauge reads more than zero (0 psi). Temporarily opening the flush valve will assist in building
up pressure in the preserving loop.
Step 8:
Allow the RO to run for than 10 minutes to allow the chemical solution to circulate through the RO.
Step 9:
Shutdown the HP PUMP and LP PUMP, respectively.
Step 10:
The system is properly conditioned and may be left idle for an extended period of time. This
preservation procedure should be repeated at least every 3 months in tropical climates during the
shutdown. In colder climates the interval between preservation cycles may be extended to 6 months. Be
sure to flush out old preservative before adding new.
