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 en-
vironment. A fresh water flush every five days (30 days with the Z-Ion) will greatly reduce biolog-
ical growth, but may not stop it completely. Both the Z-Brane or Z-Ion systems protect the mem-
brane 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
Service the pre-filters on a regular basis. The MPC will alarm when the filters reach a 10 PSI (.7
BAR) pressure differential. If you use the system until it stops at a 10 PSI differential (.75 BAR)
then the filters will have to be discarded. Extremely dirty filters will harm system performance
and may cause the feed pump to cut out from high pressure. Leaving dirty filters in the machine
during long idle periods will cause biological contamination.
To service the prefilters, turn yellow service valve on feed pump module to OFF, open the hous-
ings, and remove the old filters. Clean out the housing bowls, reassemble the housings with new
5 and 20 micron filter elements. Leave dry until the next startup. Use only Spectra-approved fil-
ters or you may void your warranty. The filters may be cleaned up to three times with a soft
brush and water in a bucket, hung overboard overnight, or dragged behind your vessel under-
way. Drying the filters in the sun helps kill microbes and remove bad smells. Occasionally, lightly
lube the filter housing O-ring with silicone grease.
Oil/Water Separator (Optional)
To install oil water separator capability, remove the 20 micron filter from the dual filter housing
and replace with the oil water separator element. 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. See page 56.
