7.3 Operations and Maintenance
7.3.1 To operate the 12 Volt DC System:
1. Switch the main battery switch in the chart table seat.
2. Switch the DC main circuit breaker at battery switch
panel to ON.
3. Switch on relevant breakers at the MDP.
Note: Always switch circuit breakers off when you leave your
boat unattended.
7.3.2 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, however for auto-
matic operation power does need to be supplied to the MDP.
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.
7.3.3 To operate the macerator pump:
Do not place facial tissue, paper towels, or sanitary
napkins in head. Such materials can damage waste
disposal systems and the environment.
Important: U.S.Coast Guard regulations require that boats
have a sanitation system on board to control pollution. Waste
is to be stored in a holding tank or other device so it can be
properly disposed of at a shore facility. Discharging this waste
overboard in the U.S. lakes, rivers, bays, and sounds and with-
in 3 miles of shore in international waters is prohibited. Check
with the Coast Guard regarding regulations in your area.
1. Power up the DC panel as described in this section.
2. Open the seacock valve located in the transom area
behind the aft bulkhead access panel.
3. Switch the MACERATOR breaker at the DC main elec-
trical panel to ON.
4. Turn the macerator switch to the “on” position at the
Nav Station. This is a momentary switch, you must hold
the switch to operate.
5. Allow the macerator to run until the holding tank is
empty, but no longer. Running the macerator when the
tank is empty will damage the pump. When full, the
macerator will have a low pitch grind. When empty, this
changes to a high pitch grind.
6. When you hear the pump speed up (indicates tank is
empty), immediately switch the MACERATOR breaker to
OFF.
7. Close the seacock.
If the seacock is not closed, the holding tank will fill
with sea water and could possibly flood the boat.
7.3.4 To operate the engine compartment blower:
Power up the DC system as discussed in this section.
Turn engine key switch to on.
7.3.5 To operate the windlass:
1. Power up the windlass from the battery switch.
2. The controls for the windlass are on the deck to the
right of the anchor well.
For more information about your windlass, refer to the
Underway Section of this manual.
7.3.6 CO Monitors
For your protection, we have installed CO monitors
aboard your boat. Be sure and check your Owner’s
Packet for more info concerning your CO detectors. You
can also review that dangers of CO in the Boating Safety
Chapter of this manual. The monitors also have 9 volt
battery installed as a backup and needs replaced annu-
ally.
Do not spray waxes or cleaning agents on the monitor.
7.3.7 Maintenance
The maintenance of your DC system is ensuring that all
connections are clean, tight, and covered with a corrosion
inhibitor compound.
