4.
If the watermaker will not be used within the next three days, treat it with membrane
preservative (see
Membrane Storage
below).
5.
Tie a line through the center of the dirty filter element and, if underway, tow it behind the
vessel for a few minutes. If the vessel is anchored, hang the dirty filter over the side of the
boat so that it is underwater, and jerk it up and down a few times to dislodge the
contaminants.
6. Dry the filter element thoroughly, preferably in the sun. Then store it for use as a clean
filter the next time the prefilter assembly is serviced.
We do not recommend scrubbing filter elements with brushes or other abrasive tools or materials, as
such treatment is unnecessary and greatly shortens the life of the filter element. If filter elements are
cleaned regularly as directed, and not allowed to become extremely dirty, they can be expected to
last for many months of service with nothing more than the gentle cleaning described above. Clean
filter elements also help assure unrestricted flow of intake seawater to the pump.
Membrane Storage, Preserving & Cleaning
The reverse osmosis membrane inside the membrane housing is an expensive and delicate compo-
nent of your system. When properly cared for, it can be expected to last for several thousand hours
of use. Improper use, maintenance or handling can damage or destroy the membrane very quickly.
Membrane Preservative Treatment
:
The primary purpose of a membrane preservative
treatment is to keep membrane moist and reduce
biological growth on the membrane surface. Over time,
biological matter can adhere to the membrane surface,
thus gradually decreasing its effectiveness. When the
watermaker is not to be used for an extended period of
time, you should preserve the membrane. A membrane
preservative treatment is effective for approximately
one year (storage temperature < 25°C/77°F). If
longer storage is required, the membrane preservative treatment should be repeated every year .
In temperate climates, the maximum period of time the watermaker should be stored without
preserving the membrane is
approximately one week. In hot or
tropical climates, the watermaker
membrane should be preserved if it will
not be used within the next three days.
Follow these directions to
preserve the
membrane of your watermaker:
1. Lift the lever on the cleaning valve
on the pump to place it in its
“clean” or “up” position (see
Figure 12 ).
2. Fill a clean plastic container or
bucket with two quarts
(approximately 2 liters) of clean
water, preferably freshwater from
the PowerSurvivor. (
Caution:
Never
use chlorinated freshwater. This may damage the membrane.)
Warning:
Be sure to follow the
flushing procedures described below to
ensure that the membrane preservative
solution does not get into the freshwater
supply.
