2. Connect Electrical Power to Pump:
To provide 12 (or 24) VDC electric power to the
motor, use a minimum of
16 gauge
(1.5 mm
2
)
stranded copper wire. We
recommend
14 gauge (2.5 mm
2
)
(or larger)
wire for distances over 20 feet (6 m). Tinned,
stranded copper wire is preferred for marine
installations and is available in most marine
hardware stores.
Figure 4
shows a typical
electrical power configuration.
3. Mount Pre filter Assembly and
3-Way Valve:
Lightly coat the male
threads of the middle port of the pre filter
3-way valve with a non-hardening,
paste-type thread sealant (e.g. Loctite 5331,
Permatex) to assure an airtight seal. (
Note:
Teflon tape is
not
recommended.)
1.
Carefully thread the middle port of the prefilter 3-way valve into the “IN” port of the pre
filter housing.
Do not over tighten
this connection. When assembled correctly, the long
axis of the 3-way valve should be vertical (See
Figure A-1
).
2.
Fasten the supplied right-angled mounting bracket for the pre filter assembly to a
bulkhead. Ideally, it should be lower than the pump intake to allow air bubbles to pass
easily. Orient it so the pre filter assembly will be vertical, with the bowl underneath. We
recommend that it be thru-bolted with corrosion-resistant hardware.
3.
Screw the top of the pre filter housing to the bracket with the supplied screws. One port of
the pre filter 3-way valve should project above the housing through the notch in the
mounting bracket.
4. Install Seawater Intake Plumbing:
There are two common approaches to providing the
seawater intake circuit:
Tee into an existing seawater intake (
e.g
., engine cooling water or manual seawater pump
inlet).
Install a dedicated thru-hull for the watermaker.
Either of these configurations should meet the following criteria:
It should be at a low point on the vessel’s hull, to minimize the chance of air intake during
heeling or rough conditions.
The thru-hull should be a minimum of 1/2" I.D., and possibly larger if it is a shared inlet.
(
Note:
If there is the possibility that in the future you will want to upgrade to a higher
capacity unit or perhaps a second
PowerSurvivor 40E
to implement redundant systems
you should consider substituting 1/2" I.D. hoses and hose fittings during your initial
installation).
An easy-to-reach seacock should be installed on the thru-hull immediately inside the hull.
A coarse seawater strainer is strongly recommended. It should be easy to reach and
clean.
The easiest and most commonly used approach is to tee into an existing seawater intake system. Be-
cause the flow rate and volume of seawater intake for the
PowerSurvivor 40E
are both extremely
low, the pump can be adequately supplied by
most
pre-existing intakes — even inlets that operate at
modest negative pressures, such as the cooling water inlet for an engine or generator.
