Maintenance
The Seawater Strainer
The sea water strainer’s stainless steel element should be inspected, removed, and cleaned as
needed. Be careful to 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, rinse, and reassemble
dry to impede corrosion. Check frequently during operation.
The Prefilter
• Service the prefilter on a regular basis. The pressure will rise on the remote gauge when the
filter becomes dirty. Extremely dirty filters will harm system performance and may cause
the feed pump to cycle on the high pressure switch. Do not leave dirty filters in the machine
during long idle periods, as biological contamination could result.
• To service the filters, shut off the service valve, open the housing, and discard the old filter.
Clean out the housing bowl, 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. The filters may be
cleaned several times with a soft brush and water in a bucket. Occasionally, lightly lube the
filter housing O-ring with silicone grease.
•
Replace the charcoal filter element at least every 6 months! This filter protects the mem-
brane by removing chlorine from the fresh flush water. Use only a Spectra replacement!
Oil Water Separator (Optional)
To install oil water separator capability install the additional filter housing with its oil removal
filter upstream of the 5 micron filter. Service at the same time as the 5 micron filter.
General
Periodically inspect the entire system for leakage and chafe on the tubing and hoses. Repair
any leaks you find as soon as practical. Some crystal formation around the Clark Pump blocks
is normal. Wipe down any salt encrusted areas with a damp cloth.

The Feed Pump and Clark Pump
The feed water pump and the Clark Pump require no routine maintenance except inspection for
leaks. Tighten any hose clamps or fittings the show signs of leakage. The high pressure fittings
threaded into the Clark Pump have O-ring seals with a straight thread. These should never leak
and should never be over tightened. If one of the tube nuts starts to leak, it can be un-threaded,
sealed with a bit of silicone grease or silicone sea, and tightened with two wrenches very
tightly.
