General
Periodically inspect the entire system for leakage and chafing. Repair any leaks as
soon as you find them. Some crystal formation around the Clark Pump blocks is normal. Wipe
down any salt encrusted areas with a damp cloth.
Watermakers are at their best when run regularly. Biological fouling in the membrane is more
likely when a watermaker sits idle. A warm environment will cause more growth than a cold
environment. A fresh water flush every five days (30 days with the Z
- Ion) will greatly reduce
biological growth, but may not stop it completely. The Z - Ion system protects the membrane
from bio - fouling without the use of storage chemicals.
The Seawater Strainer
The seawater strainer ’ s stainless steel element should be inspected, removed, and cleaned as
needed. Ensure that the thru - hull is closed before disassembly and the gasket is in place before
reassembly. When the system is put into storage, remove the strainer, rinse with fresh water,
and reassemble dry to impede corrosion. Check frequently during operation.
The Pre - filters
Prefilter elements must be changed frequently. The rate is solely dependent on the input water.
A 5
- micron filter might last you a 4 - 6 weeks in clear open ocean seawater, or be ruined in 45 in a
dirty harbor. A vessel may be sailing through seemingly super clear water, but cruise through a
plankton bloom and the prefilter will be ruined. Filters may be cleaned up to three times each
with a soft brush and water in a bucket, hung overboard overnight, or dragged behind a vessel
underway. Drying in the sun helps remove odors. However, every time you clean off a prefilter
element, sediment eventually gets forced deeper into the pleats of the prefilter, making it
eventually not very effective.
To service the filter close the thru - hull, open the prefilter housing, remove the old filter, clean
out the housing bowl, and reassemble the housing with a new 5 micron filter element. Leave dry
until next startup.
Use only Spectra - approved filters or you may void your warranty. Occasionally, lightly lubricate
the O - rings with silicone grease.
Oil/Water Separator (Optional)
To install oil water separator capability, add a second filter housing UPSTREAM of the 5 micron
housing. Service as you would per the instructions above.
