Installation
Do it right the first time and reap the rewards
The PowerSurvivor 80E 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. It can also draw water when mounted several feet above
the waterline of a vessel. Thus, the watermaker may be installed in
almost any location and
orientation.
The most important part of a good installation is proper planning. Although the design and
operating requirements of the
PowerSurvivor 80E 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 or membrane assembly:
5
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!)
5
Choose a dry area. The motor/drive assembly is not waterproof and can corrode.
5
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!
5
Find a location which allows comfortable access for routine inspection and servicing.
In addition, you should:
5
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!
5
Provide a shutoff valve or seacock in the seawater intake line.
5
Install a coarse strainer in the seawater intake line.
5
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
9
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.
9
Don’t locate the pump assembly above gear or materials that could be damaged if it
leaked.
9
Don’t locate the pump assembly near to sleeping quarters, bunks, or other areas that
are normally “quiet” areas for yourself or crew members.
