Dockside Waste Pump-Out - Four winns 248 Vista Owner's Manual

NOTICE
The macerator pump must be used to discharge
waste overboard. However, DO NOT use the
macerator pump to discharge waste at a pump-
ing station. If the hose is not air tight or connect-
ed properly, waste could spurt out or leak around
the deck fitting and into the boat.
To operate the overboard discharge system:
1. The discharge valve is located in the engine compart-
ment labeled HEAD DISCHARGE. To open, turn
the valve so that the handle is parallel to the flow of
the valve. The waste deck plate cover must be tight-
ened securely for the overboard discharge system to
operate.
2. Turn ON the macerator pump switch which is locat-
ed in the head on the switch panel. Allow the pump
to run until the storage tank is empty. The sound of
the pump's motor load and speed will change when
the tank becomes empty.
3. Turn the switch off.
4. Turn the discharge valve handle to the closed posi-
tion, and secure it. The thru-hull valve must be closed
to prevent water from being forced back into the sys-
tem.
NOTICE
Discharging waste overboard is illegal in most
U.S. waters today. Discharge is limited to cer-
tain coastal waters, a designated distance off-
shore. Check with your local boating regulations
before proceeding with any discharge activities.
Some local regulations require overboard dis-
charge systems be physically secured in a
closed position during use of the boat in waters
designated as "no discharge" areas. Check with
local boating regulations. Refer to the
manufacturer's literature for additional informa-
tion.

E. Dockside Waste Pump Out
On most Vista™ models waste pump out capability is
available. Waste can be removed from the holding tank
by taking the boat to a dockside waste pumping station.
Most marina fueling facilities provide such services.
The waste holding tank should be emptied upon visual
inspection of the waste holding tank and determining
the waste holding tank's capacity is almost full or by
using the waste level indicator if so equipped. Waste
level indicators are typically located in the head. On
the porta potti (models with pumpout option only) the
waste level indicator is located on the porta potti itself
and will change from green to red indicating the tank
should be emptied. See Figure J15. DO NOT ALLOW
THE WASTE TANK TO BECOME OVERFILLED.
Figure J15: Porta Potti w/ Pumpout Waste Level Indicator
To pump out the holding tank:
1. Be sure the head has some water in the bowl.
2. Connect the dockside pump out connection to the
WASTE plate located on the deck.
NOTICE
Usually the dockside pump out connection will
screw into the waste deck plate or has a rubber
sleeve that inserts into the plate and must be
held in position during the pump out operation.
3. Have the pumping station operator activate the pump-
ing equipment. The waste will be drawn from the
holding tank and into the pumping station's disposal
tank.
4. Remove the pump out connection from the deck plate.
Add at least 5 gallons of clean water to the holding
tank on most models through the waste deck fitting
using a dockside water hose. The exception being
the porta potti toilet with pumpout model. Add 1
gallon of water through the waste fitting.
5. Repeat steps 2 & 3 above to pump out the water
used in step 4 to flush the holding tank.
