may cause serious damage to the system’s seals
and hoses.
10.4 Head System
All vessels with fixed toilets that are operated on the
waterways of the United States and some foreign countries
are required to be equipped with an operable Marine
Sanitation Device (MSD). The Marine Sanitation System
aboard your boat is a waste tank system defined by the
United States Coast Guard as a Type III System. Type
III systems permit operation of the toilet without direct
discharge of untreated waste after every flush. Type III
systems can be discharged at a Marina, Dockside Pumpout
stations or, if in coastal waters, at least three miles
offshore.
Note: Overboard discharge capabilities must remain inoperative
while within the 3 mile limit. This is accomplished by closing the
macerator discharge through hull valve. Refer to the Mechanical
Arrangement illustration in the Boating Safety Section or the
Sanitation Arrangement illustration at the end of this section.
10.4.1 Electric Head System
These heads are typically designed to use fresh water.
There is a discharge. Between the toilet and the waste
tank is a device called a macerator that is not totally unlike
a blender or a garbage disposal in that it purees solid
waste and paper. Macerating heads require more flush
water than any other type of toilet, a minimum of 1 gallon
to rinse urine completely out of the machinery, a minimum
of 3 gallons of clear solids and paper. Insufficient flushing
shortens the life of the motor and macerator.
The 12 volt electric marine toilet comes with a compact
white vitreous china bowl and is equipped with a dual
function pump which eliminates having to mess with
hand pumps and dry bowl valves. With the simple push
of a single switch, the self-priming flush pump rinses the
bowl.
The toilet is controlled by a switch at the MDP. Refer to
the electrical sections of this manual for more information
about MDP. Refer to the location illustrations in this section
or the Boating Safety section for location information
of your sanitation system.
! CAUTION !
Do not use chlorine-based or caustic cleaning
agents, or chemicals such as a drain opening product
in your head systems. Use of these products
10.5 Operations and Maintenance
This section details the system’s operation and maintenance
on the components or systems if applicable.
10.5.1 Bilge Pumps
As we previously discussed in this section and in the
DC Electric Systems Section, your boat has a total of
two bilge pumps. The Emergency, or High Water Pump
(optional), and the standard bilge pump. We detailed the
operations of these pumps in the DC Electric Section
(Section 7).
Here are the steps mentioned in that subject:
10.5.1.1 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 MDP and switch
them to the manual position.
2. Another procedure to be used in extreme circumstances
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.
10.5.1.2 Maintenance on Bilge Pumps
No maintenance is required other than ensuring that the
float switches are operational and that there is no debris
clogging the pump intakes.
! WARNING !
Failure to close the overboard discharge valve when
not in use could cause the holding tank to fill and
possibly flood the boat.
! WARNING !
Waste in the holding tank can form methane gas.
Use suitable precautions when any maintenance is
done to the sanitary system.
