7.3.4.1 Basic Refrigerator Operation
1. On standard battery charger model, turn on house
battery selector switch (under chart table).
2. Turn on Main DC breaker at Battery Swtich Panel.
3. Set Thermostats to desired temperature.
Note: If leaving unit on when away from boat be sure
shore power cables are connected and battery char-
ger is on to prevent battery drain. (Optional inverter
equipped models charge circuit is automatic if shore
power is connected and has power to Main Distribution
Panel).
Note: Consult product manual for operating the refrig-
erator and other information on the unit.
7.3.5 Bilge Pump Systems
Your boat is equipped with 1 main bilge pump and
1 (Optional) emergency bilge pump. For locations
of the bilge pump systems, consult your Mechanical
Arrangement Drawing or the Sanitary Systems Drawing.
The Bilge Pump System consists of a pump and a float
switch. When the water level rises far enough to activate
the float switch, this activates the pump which lowers the
water level down to a point that the float switch stops the
power. Fig. 7.4 shows you the typical wiring.
For more information about your bilge pump system, see
Sanitary Systems.
7.3.5.1 To manually operate your bilge pumps:
Note: The power to the MDP does not need to be energized in
order to manually operate your bilge pumps.
1. Locate the bilge pump switches at the Nav station and
switch them to the manual position.
2. Another procedure to be used in extreme circumstanc-
es involves locating the float switch and manually rotating
the float handle on the side of the float switch to simulate
the float switch being underwater. This will energize the
pump and the pump will operate.

7.3.6 Shower Sump
The shower sump is part of the Sanitary System and
more information about the Shower Sump can be found
in that section. However, the reset for the Shower Sump
can be found on the 12 Volt DC Panel.
Fuel fumes in the engine compartment can explode.
Before working on electrical wiring, ventilate
engine room and disconnect battery cables to
prevent sparks.
7.3.7 Ventilation
Ventilation is a very important issue with your boat, with
the potential for Carbon Monoxide buildup (See Boating
Safety Section), along with the simple comfort of fresh
air or air conditioning, ventilation is a standard that is a
necessity.
On your boat, there are essentially three types of ventila-
tion, the air conditioning system (AC system), the blower,
and the Bomar hatches, which supply you with fresh
air when opened. Since the air conditioning system is
AC powered (see AC Electric Section) and the hatches
require no power, we will detail the blower (or fans), and
their function, here.
For blower location, consult your Mechanical Arrangement
