Long-Term Shutdown Procedure - Sea Recovery SRC Aqua Matic 700-1 Owner's Manual

is not equipped with the Automatic Fresh Water Flush option, or if it needs to be winterized against freezing
temperatures, follow the procedure in this topic. The procedure provides instructions for displacing the System's
Feed Water with Fresh Product Water (i.e., potable water), adds propylene glycol (if winterizing), and protects the
System during shutdown.
Caution: If the System is, or will be, exposed to freezing temperatures, do not activate the Automatic Fresh
Water Flush; instead, perform the Manual Fresh Water Rinse procedure described in this topic.
Note: 10 gallons (38 liters) of Fresh Product Water is required for the Fresh Water Rinse. Two (2) gallons
(7.5 liters) of food-grade glycerin (propylene glycol) is required for winterizing.
1. Close the Inlet Sea Cock Valve.
2. Fill a container with 10 gallons (38 liters) of Fresh Product Water.
Important: If the System is, or will be, exposed to freezing temperatures, add two (2) gallons (7.5 liters)
of food-grade glycerin (propylene glycol) to the container of Fresh Product Water. Propylene-Glycol
prevents water within the System from freezing.
3. Configure the System for a Once-Through Rinse, as described within the topic
page 54.
4. Operate the System in Manual Mode.
Note: System operation will deplete the Fresh Product Water or Fresh Product Water / Propylene-Glycol
mixture. You must STOP the System before depleting the water or water mixture.
5. Proceed to the topic
four (4) weeks.

Long-term Shutdown Procedure

Long-term (or prolonged) shutdown occurs when the System remains unused for over four (4) weeks. Before a
long-term shutdown, the System must first be rinsed with Fresh Product Water, and then with Sea Recovery
Corporation's System and Membrane Element Storage Chemical (SRC SC). SRC SC inhibits bacterial growth,
while maintaining the RO Membrane Element's high flux and salt rejection properties. If the System will be shut
down for over four (4) weeks and is not equipped with the Automatic Fresh Water Flush accessory, or if it needs
to be winterized against freezing temperatures, follow the procedure in this topic. The procedure provides instructions
for displacing the System's Feed Water with Fresh Product Water (i.e., potable water), adds propylene glycol (if
winterizing), and protects the System during shutdown. If the System is equipped with the Automatic Fresh Water
Flush accessory, then it is not necessary to read this section, as long as the Automatic Fresh Water Flush cycle
remains active, and the System is not exposed to freezing temperatures.
Important: Third-party chemicals will destroy the RO Membrane Element! Only use Sea Recovery
Corporation-supplied chemicals. Never use third-party chemicals, as they are incompatible with various
System materials and will dissolve the co-polymer parts. Damage to the System or its components as a result
of using third-party chemicals is not covered by the Sea Recovery Corporation Warranty.
Caution: If the System is, or will be, exposed to freezing temperatures, do not activate the Automatic Fresh
Water Flush; instead, perform the Manual Fresh Water Rinse procedure described in this topic.
The following items are required in preparing the System for long-term shutdown:
• 20 gallons (75.7 liters) of Fresh Product Water.
• Sea Recovery Corporation's System and Membrane Element Storage Chemical (SRC SC).
• If winterizing: Two (2) gallons (7.5 liters) of food-grade glycerin (propylene glycol).
