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-filter
Service the pre-filter on a regular basis. The MPC will alarm when the filter reaches a 10 PSI (.7
BAR) differential. If you use the system until it stops at a 10 PSI differential (.75 BAR) then the
filter will have to be discarded. Extremely dirty filters will harm system performance and may
cause system shut down. Leaving dirty filters in the machine during long idle periods will cause
biological contamination.
To service the pre-filter, close the seacock to lessen spillage, open the housing, and remove the
old filter. Clean out the housing bowl and reassemble the housing with a new 5 micron element.
Leave dry until the next startup. Use only Spectra-approved filters or you may void your warran-
ty. 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 underway. Drying the filters in the sun helps
kill microbes and remove bad smells. Occasionally, lightly lube the filter housing O-ring with sili-
cone 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.
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 64.
