Installation
Do it right the first time and reap the rewards
The
PowerSurvivor 40E
watermaker utilizes a low-volume, high-pressure,
positive displacement
pump. Unlike the centrifugal pumps found in some systems, a positive displacement pump is self-
priming. This pump’s powerful performance enables the delivery of seawater even if the desalinator
is mounted several feet above waterline. We still however recommend the use of an additional pump
(available in the “silt reduction kit”) for assembly and use of the desalinator above waterline or when
a longer hose is required.
The most important part of a good installation is proper planning. Although the design and
operating requirements of the
PowerSurvivor 40E allow much latitude for equipment location, there
are several cautions and suggestions you should consider before proceeding with an installation.
Installation DOs
When choosing a location for the watermaker drive/pump/membrane assembly:

Avoid areas with excessive heat. Ambient temperatures above 105 ° F (40° C) exceed the
ratings for the electric motor, and excessive heat can damage or destroy the membrane.
(
Note:
Most engine rooms get hotter than 105° F!)

Choose a dry area. The motor/drive assembly is not waterproof and can corrode.

Choose an area free of fuel vapors. The electric motor is not vapor-proof and
should not be
operated if explosive or flammable materials are present!

Find a location which allows comfortable access for routine inspection and servicing.
In addition, you should:

Install the pre filter assembly in an
easily accessible
location. It needs regular (sometimes
daily ) inspection and maintenance. For ease of routine maintenance, the choice for this
location is probably the single most important decision you will make — plan it carefully!

Provide a shutoff valve or seacock in the seawater intake line.

Install a coarse strainer in the seawater intake line.

We recommend using properly-sized ring terminals and a terminal strip near the pump to
connect electric power. This allows for easy testing, removal and servicing when required.
Installation DON’Ts

Don’t use a thru-hull installed high on your vessel’s hull for your source of seawater intake.
This is especially important for sailboats. Even a normal amount of heel when under sail can
cause the thru-hull to be out of the water, allowing air into the intake system. A rolling
anchorage can do the same.

Don’t locate the pump assembly above gear or materials that could be damaged if it leaked.

Don’t locate the pump assembly near to sleeping quarters, bunks, or other areas that are
normally “quiet” areas for you or crew members.
