Katadyn PowerSurvivor 80E, Owner'S Manual

Note:
Organic growth is much more rapid in warm or tropical climates. If using the
watermaker in a tropical environment, we recommend a membrane preservative treatment if
the watermaker will not be run again within the
next three days!
Before doing repairs or
maintenance work on a PowerSurvivor, close the seawater inlet valve after turning
off the system. Otherwise, the possibility exists that hose failure, for example, could
cause the boat to sink.
At the end of a watermaker run, check the condition of water in the prefilter housing. If there is
evidence of trapped material, clean the prefilter housing and install a clean prefilter element.
Special Conditions
Product freshwater output volume will vary depending on the salinity and temperature of the
seawater being processed.
Figure 6 illustrates the relationship between feed water
temperature and the quantity of product water.
Factors which are known to affect output or per-
formance 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 prefiltration. If you must
regularly process such water, consider
installing a
Silt Reduction Kit (see Kits
& Accessories ).
•
Foul Intake Seawater can seriously effect 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.
