Forward Bilge Pump - The forward bilge compartment can
be activated manually by the FWD BILGE breaker switch.
Any water from the stringers or from other sources within
the cabin will drain into the forward bilge compartment.
The pump is equipped with an automatic float switch and
will operate whenever bilge water rises to a level that will
cause the float to move upward. The water will be pumped
overboard.
Head Compartment Blower - A blower is installed in the
head compartment. A separate ON-OFF switch is pro-
vided in the head compartment. The head blower is protect-
ed by a circuit breaker on the cabin DC panel.
Pressure Water - A pressure water pump delivers water
to the faucets, shower, and transom washdown. The pres-
sure water pump will operate automatically as long as the
FRESH WATER breaker is ON in the 348 Vista.
Turn the FRESH WATER switch OFF when the water tank
becomes empty, or when water will not be required for an
extended period. The 348 comes standard with tank moni-
toring systems to check water levels. Refer to Section J-
1 and J-2 in this manual for additional information.
Cockpit Refrigerator (Optional) - A circuit breaker is pro-
vided on the DC cabin panel. The refrigerator has a sepa-
rate ON-OFF switch. Refer to Section L-2 in this manual
and to the manufacturer’s literature for additional informa-
tion.
Stereo - The stereo has a separate switch on the unit and
is protected by a circuit breaker labeled STEREO on the
12 volt cabin panel of the 348.
Sump Pump - A sump pump is used to discharge water
from the shower and sink drains overboard. It is installed
on all Vistas. The sump pump has a float switch which
will activate the pump when the water level rises in the
sump. This pump is protected by the SUMP circuit breaker
located in the 12 volt cabin panel.
If the boat is equipped with a grey water system, the water
from the shower and sinks is pumped into a holding tank
instead of overboard.

H - 5 120 (220) VOLT ELECTRICAL SYSTEM
The boat is equipped with 30 amp, 120 volt, 60 Hertz (or
15 amp, 220 volt, 50 Hertz) AC electrical wiring. When
the boat is connected to a shore power outlet, the AC
system supplies electrical power to the following items:
battery charger, refrigerator, water heater, range, micro-
wave, icemaker, and outlets. The air conditioner has its
own dockside power plug. The dockside system uses
three-wire, color-coded circuitry. The black or hot wire is
the ungrounded current carrying conductor. The white or
neutral wire is the grounded current carrying conductor.
The green wire, referred to as the “equipment ground,” is
a grounded conductor, and under normal conditions is
not a current carrying wire. The neutral wires are con-
nected together at a buss bar. The equipment grounds
are similarly connected together at another buss bar.
Each hot wire is connected to, and protected by, a cir-
cuit breaker in the distribution box.
The distribution box houses the system circuit break-
ers. The standard dockside system has a main circuit
breaker which protects the overall distribution network.
The 348’s MAIN dockside inlets are in the aft transom
storage tub. The 348 has MAIN circuit breakers on the
cabin panel. Both MAIN breakers must be turned ON
for AC system operation. The MAIN circuit breaker pro-
tects both the hot and neutral input leads. This breaker
is sensitive. The resulting power surge which occurs
when connecting the shore power cord may cause the
MAIN breaker to trip. To avoid this power spike, turn off
the MAIN breaker before plugging in the shore power
cord. Securely connect the power inlet of the boat and
the shore power receptacle. Once the shore power is
securely connected, turn the MAIN breaker back on. If
the connection is broken and later re-secured, the cir-
cuit breaker may trip. Connections must be secure for
uninterrupted dockside service.
H - 6 DOCKSIDE OPERATION
If any abnormalities appear during dockside op-
eration, DISCONNECT the system immediately
to prevent electric shock hazards! Have the
boat’s electrical system and the shoreside
receptacles checked as soon as possible.
