9.
Operate the pump handle back and forth through
its full range of travel in both directions. Pump at a
rate of approximately one complete cycle every
two seconds (one second in each direction). This is
about the same rate at which the pump is driven by
the motor during powered operation. Do not pump
too fast!
10. To return the watermaker to powered operation,
reverse the above procedure. When coupling the
pump piston shaft to the drive shaft, align the hole
in the piston shaft with the mating hole in the drive shaft, insert the coupling pin, and slide the
rubber boot over the pin to hold it in place. Then secure the drive assembly to the pump with
the four hex nuts. Tighten the nuts evenly. Do not over tighten.
Special Conditions
Product freshwater output volume will vary somewhat,
depending on the salinity and temperature of the
seawater being processed.
Figure 10 illustrates the
relationship between feed water temperature and the
quantity of product water. Factors which are known to
affect output or performance include:

High Salinity will decrease output slightly and
lead to a modest increase in current draw.
Effectively, the pump must work harder to
remove a larger percentage of dissolved solids
from the seawater.

Cold Water
will have an effect similar to that of
high salinity.
 Silt or Sand can damage the membrane and internal pump components if not removed
during pre filtration. If you must regularly process such water, consider installing a Silt
Reduction Kit (see Kits & Accessories).

Foul Intake Seawater can seriously affect the quality of the product freshwater. The
watermaker membrane is designed to remove the impurities found in clean, open
ocean seawater. Processing of seawater with other kinds of impurities (1) may
not
remove those impurities and (2) may damage or destroy the membrane. See
Maintenance and Service: Prefilter Maintenance
below for more information on typical
problems associated with foul water intake.

Low Battery Voltage will dramatically reduce the volume of seawater throughput and
product freshwater output. We recommend not operating the watermaker if battery
voltage is below 11 VDC.
Note on Red Tides
: In many areas of the ocean, a phenomenon generally known as a “red
tide” can occur. This generic name is used to describe an invasion of local waters by huge
populations of micro-organisms, which turns the seawater red. Occasionally, a red tide is
accompanied by the death of local fish and other sea life, which can cause serious local pollution
of the seawater. Although the watermaker membrane can remove the microorganisms that cause
the red tide, it can
not remove all of the chemical pollutants caused by large-scale biological
decomposition. Therefore, we do not recommend using the watermaker to process seawater when
a red tide is present.
