Chemicals are even more expensive to forward, so I have attached their descriptions to this
email. If you go to
www.ashland.com you will find at reseller I hope in your area. (Note: The
chemicals are also available from HR Parts, and Swedish Marine in Richmond, CA reports that
they can supply chemicals as well.)
It may be a little tricky to get the old membranes out, depending on the location of the pressure
vessels. At least 130 cm free space on either side is required, as the membrane itself is 120 cms
long. Alternatively, both black pressure vessels can be removed, the membranes exchanged and
then reinstalled. Also note the end caps (in white plastic) can break if you tight them too much
when putting them back. The holes are cone-shaped. Make sure you close down and start up
again according to the manual.

rd
bucket that can be less than 5 gallons for the
rinse step when cleaning, and for any slop.

Also need a carbon filter to filter source water and remove chlorine if using shore water.
In-line filter with hose fittings works well.
Pickling Procedure
1. Close seawater thru hull.
2. Close flushwater valve
3. Close feedwater shutoff valve.
4. Open pressure-regulating valve fully.
5. Set Product water valve to waste.
6. Change microfilter
1.
Clean blue filter housings in soap/bleach and rinse well.
2. Remove o-ring clean, coat in Vaseline and replace.
7. Change carbon filter
8. Turn salinity off (means product flows to waste)
9. Split one bottle of solution/powder between the two 5-gallon buckets and mix well with 5
gallons of carbon-filtered water (needs to be chlorine free) per bucket.
10. Remove plug from feed line inlet and affix service hose, which tees into the feed line.
The fitting to connect the service hose is located between the two blue filter cases in the
passageway cabinet. This service hose is used to suck the solution from the buckets into
the system. Position the service hose end in one of the solution buckets.
11. Uncoil the discharge hose, which is located in the engine room under the port cockpit
drain tube and position the end in the same solution bucket. Open the discharge hose
