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.

Running the macerator when the holding tank is
empty will cause damage to the pump.
10.5.2 Macerator Operation
1. Open the overboard discharge valve (see the mechani-
cal arrangement illustrations for locations).
2. Switch the "MACERATOR" breaker on at the DC
Panel. Hold the momentary switch on for either the fwd
or aft macerator.
3. Allow the macerator to run until the holding tank is
empty, but no longer.
4. When you hear the pump speed up, indicating the
holding tank is empty, immediately release the momen-
tary switch, switch the pump off.
5. Close the overboard discharge valve.

Failure to close the overboard discharge valve when
not in use could cause the holding tank to fill and
possibly flood the boat.

Waste in the holding tank can form methane gas.
Use suitable precautions when any maintenance is
done to the sanitary system.
10.5.2.1 Maintenance
No maintenance is required on your macerator pump.

Helpful Hint: Should the macerator pump become clogged, you
can manually rotate the internal grinder wheels by removing
the small plastic cap on the back of the macerator pump. This
encloses the screw which is attached to the grinding wheels and
by inserting a flat screwdriver, you can rotate the wheels and
possibly remove any debris clogging the pump.
10.5.3 Shower Sump
The shower sump is controlled by a rocker switch on the
vanity face.
10.5.3.1 Maintenance
Fig. 10.4 gives you an idea of how to remove the plastic
cover on the shower sump. While no maintenance is
required on the pump itself, you do need to ensure that
the holding tank is clean and free of debris for the opera-
tion to be functional.
10.5.4 Holding tanks
The holding tanks must be cleaned or pumped out when
it becomes nearly full. There are two methods for remov-
ing waste from the holding tanks, either by pumping
overboard in coastal waters, or by dockside pump-out at
a waste facility.
10.5.4.1 Overboard Pump-out Operation
See the macerator operation guide, Section 10.5.2, for
instructions on how to pump out the holding tanks.
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 U.S. lakes, rivers, bays, and sounds and within 3
miles of shore in international waters is prohibited. Check with
the Coast Guard regarding regulations in your area.
10.5.4.2 Dockside Waste Removal
To remove waste from the holding tanks at a dockside
waste facility, insert the hose from the pump-out facility
into the waste access on the coaming (Fig. 10.6) of your
boat and follow instructions at the facility. Instructions
from one facility to another may vary.
