42C System Operations - 57
and is controlled by DC electrical power.
Each toilet is equipped with an integral
vacuum breaker that prevents a back
fl
ow
of contaminated water into the potable
water supply. Vacuum energy, supplied by
the Vacuum Pump, is stored in a Vacuum
Tank and is monitored to maintain a cer-
tain level. The Vacuum Pump is controlled
by an electrical breaker switch, located
on the AC/DC Electrical Panel (Refer to
the Electrical Pages of this section in this
Owner’s Manual for the location of the
switch). As the toilet is
fl
ushed, vacuum
energy is depleted and the Vacuum Pump
will automatically activate to restore the
required level. The Vacuum Pump will
operate for approximately 30 to 90 sec-
onds until the system reaches the required
operating vacuum level. Toilet waste, both
liquid and solid, is removed by the vacuum
energy and water combination to a Waste
Tank having a capacity of forty (40) gal-
lons (The Mechanical Layout in the Sche-
matics Section of this Owner’s Manual
shows the location of the Tank).
This waste is stored in the Waste Tank
until pumped out at a proper facility. The
photo below shows the waste tank. It is
located under the forward stateroom.
MARINE SANITATION SYSTEM
All vessels with
fi
xed toilets that are op-
erated 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
in your
42C
is a Waste Tank system, de
fi
ned by the
United States Coast Guard as a Type III
System. Type III Systems permit operation
of the toilet without the direct discharge
of untreated waste after every
fl
ush. Type
III Systems can be discharged at marina
dockside pump-out stations or, if in coastal
waters, at least three (3) miles offshore.
NOTE:
Overboard discharge capability
must remain inoperative while within the 3
mile limit. This is accomplished by closing
the macerator discharge thru-hull valve.
Refer to the Mechanical Layout Schematic
in the Schematic Section of this Owner’s
Manual for the location of the valve.
Your
42C
is equipped with one of the
following
Marine Sanitation Systems
,
depending on the option you chose from
your Silverton Dealer at the time of pur-
chase:
•
SeaLand
Vacu-Flush Toilet
•
Jabsco
Quiet-Flush Electric Toilet
(Fresh Water)
•
Jabsco
Electric Toilet
(Raw
Water)
SeaLand
Vacu-Flush Toilet
This system is operated by vacuum, com-
bined with a small quantity of water sup-
plied by the pressurized fresh water sys-
tem (approximately one (1) pint per
fl
ush)
