out by a waste dumping station or the overboard
diaphragm discharge system.
The fluid level in the waste/holding tank is moni -
tored by the monitoring feature in the CZone dis-
play or a lighted LED symbol in the in the center of
the toilet control panel. The symbol lighted green
indicates the holding tank is less than half full.
Symbol light yellow indicates the tank is at least
half full. Symbol lighted red indicates the tank is
full and flushing is not recommended. A lockout
system built into the control panel prevents the
toilet from flushing when the holding tank is full.
Refer to the toilet manufacturer owner’s manual
for more information on the operation of the ma-
rine head system.
Head System Holding Tank
The holding tank is located in the forward bilge.
When the tank is full, the red light on the toilet
control panel will be lit, indicating that flushing is
not recommended. The Black Water Tank Sender
monitoring feature in the CZone display will also
indicate the holding tank is full. The tank must
either be pumped out by the optional overboard
discharge pump or an approved waste dumping
station through the waste deck fitting.
A lockout system built into the toilet prevents it
from flushing when the holding tank is full. You
should not attempt to bypass the lockout and
flush the toilet when the tank is full. An overfilled
holding tank will force waste into the holding tank
vent filter. This will clog the vent filter and could
cause damage to the holding tank. It will also
cause unpleasant odors in the cabin and cockpit.
Use the following procedure to pump out the hold-
ing tank with the overboard diaphragm discharge
pump system:
• Open the waste discharge valve in the forward
bilge.
• Use the CZone control feature to activate the
overboard diaphragm discharge pump.
• Monitor the pumping operation closely using
the CZone Black Water Tank Level monitor
as the tank is drained and turn the pump off
immediately when draining is complete.
• Close the overboard discharge valve.
Notice:
In order to comply with current State,
Federal and Coast Guard regulations, the
Overboard Discharge valve in the forward
bilge must be closed whenever the boat is
operating in areas in which the discharge of
sewage is prohibited.
CAUTION
IN MANY AREAS IT IS ILLEGAL TO PUMP HEAD WASTE
DIRECTLY OVERBOARD. VIOLATION OF THESE POLLUTION
LAWS CAN RESULT IN FINES OR IMPRISONMENT. ALWAYS
KNOW THE LAW FOR THE AREAS IN WHICH YOU BOAT.
NEVER DUMP HEAD OR HOLDING TANK WASTE OVERBOARD
ILLEGALLY.
