as described below. Deactivate the Automatic Fresh Water Flush cycle by pressing the “Stop” switch twice (2
times).
MANUAL FRESH WATER RINSE PROCEDURE: Follow the directions below if the system is not equipped with
an Automatic Fresh Water Flush accessory. This procedure displaces the system feed water with fresh water and
allows a short-term shutdown for up to four weeks. Five gallons (19 liters) of fresh product or potable water is
required for the fresh water rinse.
1. Close the Cock Valve [2].
2. Fill a 5-gallon container with clean, fresh water.
3. Configure the system for a Once Through Rinse.
4. Fully open the Back Pressure Regulating Valve [17] counter clockwise.
5. Press the “Start” switch. The fresh water rinses the system and discharges out to waste [18].
6. 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.
7. Just prior to depleting the rinse water from the bucket, fully open the Back Pressure Regulator Valve [17] counter
clockwise and stop the system.
IN NON FREEZING TEMPERATURES, THE SYSTEM MAY NOW BE LEFT UNATTENDED FOR SEVERAL
WEEKS. HOWEVER, IF THE SYSTEM WILL BE EXPOSED TO FREEZING TEMPERATURES, CONTINUE
WITH THE FOLLOWING PROCEDURES:
8. Again, fill a 5-gallon container with clean, fresh water. Add twenty percent (1 gallon / 4 liters) food grade glycerin
(propylene glycol) to the Storage Chemical Solution. This prevents the water in the system from freezing.
9. Configure the system for a Once Through Rinse.
10. Fully open the Back Pressure Regulating Valve [17] counter clockwise.
11. Press the “Start” switch. The fresh water rinses the system and discharges out to waste [18].
12. Just prior to depleting the rinse water from the bucket, fully open the Back Pressure Regulator Valve [17] counter
clockwise and stop the system. Deactivate the Automatic Fresh Water Flush Cycle by pressing the “Stop” switch
twice (2 times).
13. Reconfigure the system for normal operation by reconnecting the Sea Strainer [3] outlet line, or reposition the
Inlet Rinse/Clean 3-way ball valve [30] to normal operation position. The system is now exposed to fresh rinse
water and may be left unattended for up to four weeks.
14. 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 Manual Fresh Water Rinse Procedure should be repeated every four weeks if the system is not in use and if
the system does not have the Optional Automatic Fresh Water Flush.
Long Term Shutdown
Long Term or Prolonged Shutdown is a period in which the system goes un-used for longer than three months,
depending on conditions. For this interval, the system should first be rinsed with fresh water then stored with system
and Membrane Element Storage Chemical (SRC SC). This chemical inhibits bacterial growth while maintaining
the high flux and salt rejection of the R.O. Membrane Element. The Long Term Shutdown procedure requires 10
gallons (38 liters) of potable water. Follow the directions listed below.
WINTERIZING AND FREEZING TEMPERATURE STORAGE NOTE: If the system is exposed to freezing
temperatures, add twenty percent (1 gallon / 4 liters) food grade glycerin (propylene glycol) to the Storage Chemical
Solution. This prevents the water in the system from freezing.
1. Close the Cock Valve [2].
2. Replace the Pre-filtration Cartridges [6] with new Sea Recovery Pre-filtration Elements.
3. Fill a clean 5-gallon container with non-chlorinated product water.
