Long-Term Shutdown - Sea Recovery Ultra Whisper Series Owner's Manual

IN FREEZING TEMPERATURES, THE SYSTEM MAY NOW BE LEFT UNATTENDED DURING THE FREEZING
TEMPERATURE SEASON. AFTER THE SEASON, THE SYSTEM SHOULD BE RINSED WITH STORAGE
CHEMICAL IF IT WILL NOT BE OPERATED.

Long-Term Shutdown

A long-term or prolonged shutdown is a period in which the system is not used for longer than 3 to 4 months,
depending on conditions. For this interval, the system should first be rinsed with freshwater, 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 RO Membrane Element. The long-term shutdown procedure requires 10 gallons
(38 liters) of potable water. Follow the directions listed below.
Important: If the system will be exposed to freezing temperatures during non-use, have ready (1 gallon /
3.8 liters) food-grade glycerin (propylene glycol), and follow instructions to add it to the storage chemical
solution. This prevents the water in the system from freezing.
Caution: Do not use storage chemicals in the R.O. Boost. Doing so in a long term storage will damage the
internal of the R.O. Boost. Please follow the storage closed loop configuration for storing your system.
1. Configure the system for a "Once-Through Depressurized Rinse" using the Product Relief Tube Kit.
2. Close the Inlet Sea Cock Valve.
3. Clean the Sea Strainer Mesh Screen.
4. Clean the Plankton Filter Element.
5. Replace the pre-filtration cartridges with new 5-micron Sea Recovery pre-filtration elements.
6. Fill the Rinse/Clean Solution Container with non-chlorinated product water.
7. Start the system. The rinse water rinses the entire system and discharge to waste.
8. Just prior to depleting the rinse water from the Rinse/Clean Solution Container, stop the system by pressing
the "START/STOP" button twice to stop the system and also to abort the freshwater flush cycle.
9. Once again, fill the Rinse/Clean Solution Container with non-chlorinated product water.
10. If the system will not be exposed to freezing temperatures, then skip to Step 13.
11. Add 1-gallon (3.8 liters) of food grade glycerin (propylene glycol) to the water in the Rinse/Clean Solution
Container. This prevents the system from damage in freezing temperatures.
12. Operate the system by pressing the "START/STOP" button. The propylene glycol solution will flow through
the system and recirculate. After 5-10 minutes, stop the system by pressing "START/STOP" button.
13. Configure the system for a storage closed loop. (Refer to diagram below)
14. Add ONLY 4 ounces (1/6th of the container) of SRC SC storage chemical to the water or propylene glycol
solution in the Rinse/Clean Solution Container.
15. Mix and thoroughly dissolve the solution in the Rinse/Clean Solution Container.
16. Operate the system by pressing the "START/STOP" button. The storage chemical solution flows from the
container, through the system, and out the brine discharge thru-hull fitting. After 5-10 minutes, stop the
system by pressing "START/STOP" button.
17. Discard any remaining winterizing solution in a safe, environmentally friendly and legal manner.
18. Reconfigure the system for normal operation:
a) Leave the Sea Cock Valve closed.
b) Reconnect the Sea Strainer outlet line to the outlet of the Sea Strainer or reposition the Inlet Clean Rinse
Valve to the normal operating position.
c) Remove the Product Relief Tube Kit.
d) Reconnect the High-Pressure Hose.
16. The Sea Strainer and post-filtration chapter have not received storage and winterizing solution in this process.
The water must be drained from the respective components.
a) Remove the Sea Strainer bowl from the Sea Strainer and drain the feed water from it. Replace the Sea
Strainer bowl back onto the Sea Strainer.
b) Remove the charcoal filter bowl from the charcoal filter, clean the inside of the bowl and replace the element
with a new Sea Recovery charcoal filter element.
