It.will.be.necessary.to.remove.the.top.holding.tank..
of the portable head to fill with water. Refer to the
manufacturer's.literature.included.in.the.owner's.

J - 7 SYSTEM MAINTENANCE
Be.sure.the.battery(s).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
methane, a colorless, odorless gas 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 any screens..The.stainless.
steel.vent.cap.is.not.removable..
NOTICE
Failure to keep the water tank vent fitting clean
will cause excessive pressure buildup within
the tank during filling. This can cause water
tank damage.
B. Winterizing the Water System
Winter.lay-up.service.procedures.should.include.a.
thorough.draining.of.the.water.system..Disconnect..
all accessible fittings. Blow out all lines. Be sure the
water.tank,.waste.tank,.pumps.and.lines.are.com-
pletely.dry..Freezing.water.can.cause.severe..
damage.to.all.water.system.components.
NOTICE
It may be necessary to disconnect the hose
below the faucet to remove excess water in
the lines to prevent freeze damage.
Water and Waste Systems - Section J
NOTICE
Always winterize the fresh water system prior
to winterization of the hull drainage (bilge
pump) system.
Draining.the.system.as.mentioned.can.be.very.tedious.
and.an.incomplete.job.can.result.in.expensive.repairs..
The.use.of.nontoxic.antifreeze.(such.as.RV.anti-
freeze).designed.for.fresh.water.systems.considerably.
reduces.the.work.necessary.and.is.a.more.positive.
means.of.winterizing.the.system..Follow.the.directions.
included.with.the.antifreeze.solution..
To.winterize:
1.. Turn.on.the.water.pump/faucet.and.drain.the..
water.tank..The.water.tanks.on.some.models.can.
be.drained.by.removing.the.withdrawal.hose.from.
the.tank.and.allowing.water.to.drain.into.the.bilge.
NOTICE
DO NOT run the water pump without water
in the system. Pump damage can result.
Be watchful and turn the pump off as soon
as the tank becomes empty.
2.. Add.1/2.gallon.of.RV.non-toxic.antifreeze.to.the.
water.tank..
3.. Turn.ON.the.pump.until.undiluted.antifreeze..
is.seen..
Use only nontoxic antifreeze solutions such
as RV antifreeze. DO NOT use ethylene glycol
solutions (the type that is used in engine
coolant systems). These are toxic.
NOTICE
Be sure to wipe up any antifreeze that has
been spilled on the fiberglass surfaces to
prevent possible discoloration or damage
to the gel coat.
