Maintenance
The Seawater Strainer
The sea water strainer
’
s stainless steel element should be inspected, opened, and cleaned as
needed. Check frequently during operation.
The Prefilter
Service the prefilter on a regular basis. The pressure will rise on the pressure 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 cut
-
out switch. Do not leave dirty filters in the ma-
chine during long idle periods, as biological contamination will result.
To service the filter, swing it out of the case, 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 filter may be cleaned
several times by soaking it in water in a bucket. Occasionally, lightly lube the filter housing O
-
ring with silicone grease.
General
Periodically inspect the entire system for leakage and chafe on the tubing and hoses. Re-
pair 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. If any rust ap-
pears at the stainless steel fittings, clean them up promptly. Keep the inside of the case dry
and salt free to protect the electrical components inside.
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 that 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 seal, and tightened with two
wrenches very tightly.
