Long Term Storage Procedures
Watermakers are best run continuously. When not in use, biological growth in the mem-
brane is the leading cause of membrane fouling. A warm environment will cause more
growth than a cold environment. The fresh water flush system will greatly reduce biologi-
cal growth but may not stop it completely in certain conditions. If an optional “Zeta Guard”
or Z-Brane water treatment system is installed in the system, then three to five day flushing
intervals will maintain the system as long as fresh water is provided and the charcoal filter
maintained.
System Storage or “Pickling”
If the system is to be left unused for more than five days, perform the following storage pro-
cedure. The procedure introduces a chemical compound into the system that prevents bio-
logical growth. This procedure requires de-chlorinated water which can be made with the
charcoal filter. Charcoal filters last a maximum of 6 months once wetted.
Spectra SC-1 a special storage compound used by the US Navy. It is formulated to be
compatible with the modern engineering plastics and composites in the Spectra pumps.
Do not use any substitute except propylene Glycol, If you chose to use glycol follow the
winterizing instructions. SC-1 Storage Compound has to be mixed at a ratio of 1 Spectra
container to 3 gallons (12L) of fresh water to have the proper solution for short term stor-
age (under two months use 1/2 of a container)
Caution! Avoid contact with skin, eyes, or lungs with the storage chemical.
