fan is turned on with a circuit breaker labeled Refrigerator Fan and will operate with either the Cold
Plate or the Evaporator system operating.
It is important to not open the refrigerator any more than absolutely necessary in order to minimize the
amount of time we need to run the engine to keep the refrigerator cool with the freezer plate or the
amount of electricity consumed with the evaporator plate.
4. Lectrasan Unit and Head
The Lectrasan unit is located in compartment 1 of the aft starboard cabin. It serves only the head that
opens into the main salon. Operation of the head is the same as for a normal marine head except that
after flushing one pushes the blue button on the wall in back of the head. This starts the Lectrasan
operation. In order for the unit to function properly it is necessary that the salt content of the flushing
water be near to that of sea water. If sailing in water with a lower salt content (like the Chesapeake
Bay) it is necessary to mix some strong salt solution with the flushing water. This is done using a small
tank located under the sink in this head. A tube with a pinch valve carries the strong salt solution to the
head by means of a mixing jet in the water intake piping. The amount of solution used per stroke of the
head flushing mechanism is controlled by the amount of pinch that the control valve places on the
tubing. When operating in ocean water the valve should be completely pinched closed. When operating
in fresh water the valve should be completely open. In brackish water the valve would be somewhere
between wide open and closed.
F. Electrical
1. Electrical Panel
Before anything electrical works on the yacht, it first has to be switched on at the panel located on the
starboard side of the main cabin above the navigator table. While many devices, such as cabin lights,
switch on first at the electrical panel and then have their own switches, others such as navigation lights,
are only switched on at the panel and must be kept switched off when not in use. There is an electrical
test meter on the panel, operated by a black two-way switch. This registers the voltage charge in each
of the batteries. Battery 1 is the house battery. The switch only reads battery charge voltage properly
with every thing switched off and should never be allowed to drop below 12 volts. With the lights and
other things on the reading should not go below 11 volts. Battery 2 is the engine battery and its voltage
should never drop below 12.3 volts. If voltage drops below these levels the engine should be started to
recharge the batteries.
The entire battery system is controlled by a Heart Interface Link 2000-R system located on the
navigation station control panel at the lower left. The operation of this system is described in the
manuals stored in the file box in the forward cabin. The system monitors and controls the charge level
for both the house battery bank (1) and the starting battery (2). You select which battery you wish to
monitor by pushing the appropriate button (a green light will indicate which battery is being
monitored). You select the function to be read by pressing the appropriate button. You can monitor the
voltage, the amperage flowing to or from the selected battery, or the cumulative amp-hours that have
flowed from the selected battery since it was last charged. Never let the cumulative amp hours for
battery 1 exceed –180 amp-hours nor let the cumulative amp hours for the starting battery exceed –20
amp hours. Before they reach these levels start the engine or plug in the battery charger if in a marina
and recharge the batteries.
