5.4 LONG TERM SHUTDOWN:
A Long Term or Prolonged Shutdown is a period in
which the system is not used for longer than three to
four 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 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.
1. Configure the System for a "Once Through De-
pressurized Rinse" using the Product Relief Tube
Kit as illustrated on page 6 of this section and as
described in item 5.2.C page 8 and 9 of this
section.
2. Close the Inlet Sea Cock Valve [2].
3. Clean the Sea Strainer [4] Mesh Screen.
4. Clean the Plankton Filter Element [7].
5. Replace the Pre-filtration Cartridges [13 & 14]
with new 25 and 5 micron Sea Recovery Pre-
filtration Elements.
6. Fill the Rinse/Clean Solution Container [38] with
non-chlorinated product water.
7. Start the system. The rinse water rinses the entire
system and discharging to waste [22].
8. Just prior to depleting the rinse water from the
Rinse/Clean Solution Container [38] stop the
system by pressing the stop switch twice to stop
the System and also to abort the Fresh Water
Flush Cycle.
9. Once again, fill the Rinse/Clean Solution
Container [38] with non-chlorinated product
water.
11. Add ONLY 4 ounces (1/6 th of the container) of
SRC SC Storage Chemical to the water in the
Rinse/Clean Solution Container [38].
12. Mix and thoroughly dissolve the solution in the
Rinse/Clean Solution Container [38].
13. If the system will be exposed to freezing
temperatures use add 1 gallon (4 liters) food grade
glycerin (propylene glycol) to the Storage Solution
Mixture. This prevents the System from damage
in freezing temperatures.
14. Operate the system by pressing the "Start"
Switch. The Storage Chemical Solution flows
from the container, through the System, and out
the brine discharge thru hull fitting [22]
15. Discard any remaining Winterizing Solution in a
safe, environmentally friendly, and legal manner.
16. Reconfigure the System for normal operation:
a. Leave the Sea Cock Valve [2] closed.
b. Reconnect the Sea Strainer [4] outlet line to the
Outlet of the Sea Strainer, or reposition the
Inlet Rinse/Clean Valve [36] to the normal
operating position.
c. Remove the Product Relief Tube Kit
d. Reconnect the High Pressure Hose [21]
18. The Sea Strainer [4] and Post Filtration Section
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
b. Remove the Charcoal Filter bowl from the
c. Remove the pH Neutralizer Filter bowl from
section 5 page 12 of 16
Sea Recovery Ultra Whisper Rev. A
Strainer [4] and drain the Feed Water from
it. Replace the Sea Strainer bowl back onto
the Sea Strainer [4].
Charcoal Filter [28], clean the inside of the
bowl, and replace the element with a new
Sea Recovery Charcoal Filter Element.
the pH Neutralizer Filter [29], drain the
Product Water from it and clean the inside
of the bowl. Replace the pH Neutralizer
Bowl back onto the pH Neutralizer Filter.
