Dockside Waste Pump Out; System Maintenance; Clean Vents And Screens - Four winns 318 VISTA Owner's Manual

NOTICE
Discharging waste overboard is illegal in most
US waters today. Discharge is limited to
certain coastal waters, a designated distance
offshore. Check with your local boating
regulations before proceeding with any
discharge activities.
Some local regulations require overboard
discharge 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
information.

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..DO.
NOT.ALLOW.THE.WASTE.TANK.TO.BECOME.
OVERFILLED.
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. 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.
3.. Have.the.pumping.station.operator.activate.the.

Be careful when handling and storing
treatment chemicals. Not only are they toxic,
but they will also stain and damage
surrounding surface.

SYSTEM MAINTENANCE

Information.supplied.with.water.and.waste.system.
components.by.the.equipment.manufacturers.is.
included.with.this.manual..Refer.to.this.literature.for.
additional.operation.and.service.information.
Be.sure.the.batteries.in.the.boat.are.properly.charged.. .
Operating.the.pressure.pump.from.a.battery.with.a.
low.charge.will.result.in.pump.cycling..This.could.lead.
to.premature.pump.failure..
The decomposition of waste produces a
colorless, odorless gas, methane, that is lighter
than air, combustible, and extremely lethal.
Always provide sufficient ventilation when
effecting repairs to the waste system and allow
no odor from the waste system to go
unresolved.
A. Clean Vents and Screens
Periodically,.inspect.the.water.tank.vents.and.thru-hull.
vent fittings for any dirt, wax, etc. Carefully remove
any.obstruction.with.a.pipe.cleaner.or.similar.device...
Be sure not to puncture the screen..The.stainless.
