Operations And Maintenance - Hunter 50CC Operation Manual

10.4.1 Electric Head System
These heads are typically designed to use raw 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 sec-
tion or the Boating Safety section for location information
of your sanitation system.
In Fig. 10.5, you will find a general outline illustration for
the Electric Head systems. This illustrations will give you
an idea about the components in the system and the rout-
ing of the waste lines.

10.5 Operations and Maintenance

This section details the system's operation and mainte-
nance 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 four
(4) bilge pumps. The Emergency, or High Water Pump,
and the fwd, mid, and aft bilge pumps. 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 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.
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.
CAUT I ON
!
Running the macerator when the holding tank is
empty will cause damage to the pump.
10.5.2 Macerator Operation
1. Open the macerator discharge valve ( The discharge
valve locates in main bilge discharge compartment by
inboard side of galley).
2. Switch the "MACERATOR" breaker on at the DC
10.6
and hoses.
