Long Term Storage Procedures
Watermakers are best run continuously. When not in use, biological growth in the membrane
is the leading cause of membrane fouling. A warm environment will cause more growth than a
cold environment. If the system is to be left unused for more than five days, perform the fol-
lowing storage procedure. The procedure introduces a chemical compound into the system
that prevents biological growth. This procedure requires de

special storage compound, formulated to be compatible with the modern engineering plastics
and composites in the Spectra pumps.
Do not use any substitute
except propylene glycol

on the container. SC

1 storage compound must be mixed at a ratio of 1 packet to 3 gallons
(12L) of fresh water to have the proper solution for up to six months storage.
Caution! Avoid contact with skin, eyes, or lungs with the storage chemical.
Aquifer Storage Procedure
The watermaker can be stored for periods up to six months using this procedure.
1. Make or buy 4 gallons of chlorine
-
free water and put it in a bucket.
2. Place the end of the feed hose in the bucket and the brine hose to drain.
3. Start and run the feed pump until you have one gallon of fresh water left in the bucket.
4. Mix 1 packet of SC

1 storage compound with the water in the bucket and place the end of
the brine service hose in the bucket.

Clean Up
•
Remove the 5 micron filter element from its housing and put in a dry one.
•
Rinse and dry the inside of the case, being careful not to get water inside the pump motor.
•
Charge the battery.
•
Remove the hoses, drain them, and stow them away in the case. Insert the hose connec-
tion plugs in the hose fittings.
