PRESSURIZED WATER SYSTEM

The.water.pump.is.an.automatic,.on-off,.self-priming.
pump.that.can.service.several.outlets.at.once..The.
pump.will.build.up.water.pressure.and.will.turn.off.
when.it.reaches.60.psi..Refer.to.Figure.J-2.and.the.
drawings.at.the.end.of.this.section..
A. Priming the System
After filling the water tank, open all faucets partially.
Activate.the.FRESH.WATER.circuit.breaker.switch..
on.the.cabin.AC/DC.panel.to.supply.the.system.with.
water..Let.the.pump.run.until.water.comes.out.of.the.
galley.faucet,.head.faucet.and.transom.shower.
After.all.the.air.has.been.purged.from.the.system.and.
a steady flow of water is coming from each outlet, turn
off.the.faucets.one.by.one..Begin.with.the.cold.water.
faucets.and.continue.until.all.faucets.are.shut.off..As.
the.pressure.builds,.the.pump.will.automatically.shut.
off.at.60.psi..Refer.to.Section.H-5.-.12.Volt.Electrical.
Equipment.and.the.manufacturer's.literature.included.
in.the.owner's.packet.for.additional.information.
B. System Operation
When.properly.primed.and.activated,.the.pressurized.
water.system.can.be.used.in.the.same.manner.as..
the.water.system.in.a.home..An.automatic.pressure.
sensor.in.the.water.pump.keeps.the.system.pressur-
ized..Simply.turn.on.the.faucet.and.water.will.be.
delivered. If the system has been recently filled, or .
has.not.been.used.for.an.extended.period.of.time,..
air.bubbles.may.accumulate.at.the.pump.and/or.in..
the.waterlines..If.this.should.happen,.re-priming.may.

be.necessary..Refer.to.the.preceding.subsection.
regarding.priming.the.system.
To.obtain.the.most.consistent.mixture.of.hot.and.cold.
water,.turn.the.cold.water.on.full,.then.mix.in.hot.water.
until.the.desired.temperature.is.obtained..If.water.
pump.cycling.occurs,.some.minor.variations.in.water.
temperature.can.be.expected..
Whenever.the.boat.will.be.left.unattended.for.an.
extended.period,.the.water.pump.circuit.breaker.
switch.should.be.turned.to.the.OFF.position..This.
switch.should.also.be.turned.OFF.whenever.the..
water.tank.is.to.remain.empty.for.an.extended.period.
of.time.
C. Water Heating Systems
A.water.heater.is.a.standard.feature.available.on.the.
318.Vista .models..The.capacity.of.the.water.heater.

Refer.to.Figure.J-3.and.to.the.drawings.at.the.end.of.
this.section.
NOTICE
Water heater location may vary due to the
installation of optional equipment.
The.water.heater.utilizes.120.volt.(220.volt.on.50.
Hertz.models).power..The.water.heater.breaker.switch.
is.located.on.the.cabin.120.Volt.AC.panel.
NOTICE
DO NOT supply 0 volt power to an empty
water heater. Damage to the heater will result
immediately. The water system must be filled
and primed before attempting to use the water
heater.
