Maintenance
The Seawater Strainer and 50 Micron Filter
•
The sea water strainer’s stainless steel element should be inspected, removed, and
cleaned as needed. A clogged strainer or 50 micron filter will cause the MPC control to
alarm
“Check Sea Strainer.” Be careful to ensure that the thru-hull is closed before
disassembly and the seal and element are in place before reassembly. Put the screen up
to a light for inspection. When the system is put into storage, remove, rinse, and reas-
semble dry to impede corrosion. Check frequently during operation.
•
The 50 micron filter needs to be properly maintained to protect the feed pump. Only
use Spectra approved filters. These may be cleaned several times before discarding.
The Prefilters
•
Service the prefilters as soon as possible after the first prefilter alarm sounds. When the
second alarm sounds the system will shut down to prevent damage. If cleaning and re-
using filter elements, clean when the first segment appears on the filter condition bar
graph on the LCD display.
•
To service the filters shut off the thru-hull, open the housings, discard the old filters,
Clean out the housing bowls, reassemble the housings with new 20 and 5 micron filter
elements. The 5 micron filter goes downstream from the 20 micron. 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 O-rings with silicone grease.
The Charcoal Fresh Water Flush Filter
•
Replace the charcoal filter element at least every 6 months.
Oil Water Separator (Optional)
To install oil water removal capability, remove the supplied 20 micron filter element in the
duplex filter set and replace with the 20 micron oil water separator cartridge. Replace this
when the MPC alerts you with a “Service Prefilter” alarm.
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.
