Introduction to Storage Chemicals
We use four types of chemicals: SC - 1, SC - 2, SC - 3, and propylene glycol antifreeze. SC - 1 and
propylene glycol are for system storage, while SC - 2 and SC - 3 are for membrane cleaning.
Note: Never use any chemicals with the system pressurized! Always open the pressure relief
valve 1/2 turn. Always follow the instructions for purging the chemicals as shown in the New
System Startup section of your owner
’ s manual.
Storage: SC - 1 prevents biological growth when your system is idle. It should not be used as a
cleaning chemical, nor will it protect your system from freezing. A jar of SC - 1 is mixed with 2
gallons (8 ltr.) of product or un - chlorinated fresh water in a bucket and circulated through the
system for 10 minutes. This treatment will protect the system for six months, after which the
SC
- 1 treatment must be repeated.
Spectra systems should be stored with propylene glycol if freezing is likely to occur. This is a
food grade antifreeze used to winterize RV
’ s, boats, and cabins. Propylene glycol also works
very well for preventing biological growth in warm climates and is good for one year. See Win-
terizing with Antifreeze (OP - 1 document on the Spectra website).
Note: Do not use Sodium Metabisulfite (SBS), Citric Acid, or any other storage chemical not
supplied by Spectra.
These chemicals, used to store other watermaker brands and will dam-
age the Clark Pump and void the warranty.
Cleaners : Avoid unnecessary cleaning, and avoid cleaning as a diagnostic tool.
SC - 2 is an alkaline cleaner used to remove light oil, grime and biological growth. It is most
effective if heated to 100 deg. F (38C). In most cases the water quality will increase in PPM
(salinity) after an SC
- 2 cleaning. After a few hours it should recover to near the level it pro-
duced before the cleaning
.
SC - 3 is an acid cleaner used to remove mineral and scale deposits. In most cases this is used
first and if there is no improvement, go on to the SC - 2. SC - 3 will in most cases lower the prod-
uct PPM and overall pressures. Scaling is a slow process that may take several months or
years.
For cleaning with either SC - 2 or SC - 3, see the Cleaning Procedure .
