CHAP. E
There are several seawater intakes located in
the bilges. These are fitted with cut-off valves,
and supply water to the following systems:
- engine cooling (the seawater intake is
incorporated in the saildrive),
- toilet flushing pumps,
- suction for galley pedal pump.
The pedal pump draws in water from a three-
way valve that allows it to be supplied with
either seawater or freshwater.
After using seawater, to avoid salt deposits
it is advisable to set this valve back to the
freshwater position, and to pump 3 or 4 times
to eliminate residual seawater remaining in
the system.
Naturally, the dirtiness of seawater filters
will depend on the condition of the water in
which you are sailing. It is therefore impossible
to give a fixed schedule for checking and
cleaning these filters. However, the experience
acquired with your boat will help you to make
these checks at correct intervals.
It should always be remembered that,
unfortunately, residues from plastic bags
can be sucked up through seawater intakes.
You should therefore acquire the habit of
making frequent checks on thermometers, on
E.2 SEAWATER CIRCUITS
The water heater can operate electrically only
if the shore power line is connected, but it also
has a plumbing connection with the sealed
engine cooling circuit. With this connection,
the water heater can heat freshwater when
the engine is running, and therefore very
cheaply, recycling heat energy that would
otherwise be dispersed into the sea by the
propulsion engine cooling system.
A thermostat valve fitted near the water
heater allows the temperature in the hot
water distribution system to be regulated,
preventing it from causing scalds and making
hot water reserves last longer. The valve
automatically mixes hot water supplied by the
water heater (which can reach temperatures
over 90°C) with cold water.
It is a recommended hygiene precaution to
pour disinfectant solution into the water
loading system with every two complete
refills made. Consult a pharmacy for a suitable
product.
When the boat is put into winter storage,
it is advisable to pour a large quantity of
concentrated disinfectant into the water
tanks, and to then empty it by opening all taps
and other outlets. This will prevent the growth
of bacterial colonies in the freshwater system.
IT IS ESSENTIAL TO CONSTANTLY
MONITOR SEAWATER INTAKES AND
CIRCUITS, TO AVOID THE RISK OF
FLOODING.
WARNING
AFTER USING THE GALLEY SINKS
PEDAL PUMP WITH SEAWATER, IT
IS ADVISABLE TO WASH IT SEVERAL
TIMES WITH FRESHWATER, SETTING
THE THREE-WAY VALVE TO THE
FRESHWATER POSITION.
