Maintenance
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 envi-
ronment. A fresh water flush every five days (30 days with the Z - Ion) will greatly reduce biologi-
cal 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 need-
ed. Ensure that the thru - hull is closed before disassembly and the gasket is in place before reas-
sembly. When the system is put into storage, remove the strainer, rinse with fresh water, and reas-
semble dry to impede corrosion. Check frequently during operation.
The Pre - filters
Service the pre - filters as soon as possible after the pre - filter condition graph begins to rise. If the
filter condition graph gets all the way to “ Replace ” the machine will slow down. When display
reaches “ Replace ” a second time, the alarm will sound and the system will shut down to prevent
damage.
To service the filters close the thru - hull, open the housings, remove the old filters, clean out the
housing bowls, and reassemble the housings with new 20 and 5 micron filter elements. The 5 mi-
cron filter goes downstream from the 20 micron. 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 20 and 5
micron housings. Service as you would per the instructions above.
The Charcoal Fresh Water Flush Filter
Replace the charcoal filter element at least every 6 months. This filter protects the membrane by
removing chlorine from the flush water. Use only a Spectra - approved replacement.
