EQUIPMENT INSTALLATION
General Warnings And Safety Information Electrical
There.are.no.user-serviceable.parts.in.the.AC.adapter,.motor,.or.
controller..In.the.event.of.a.failure,.these.should.be.replaced.
• All.electrical.connections.must.be.completed.according.to.
local.codes.
• Use.only.the.power.AC.adapter.that.is.supplied..If.the.AC.
adapter.is.replaced.use.a.Class.II,.12.volt,.150.mA.supply.
• The.power.outlet.must.be.grounded.and.always.on.
• To.disconnect.power,.unplug.the.AC.adapter.from.its.power.
source.
• Install.an.appropriate.grounding.strap.across.the.inlet.
and.outlet.piping.of.the.water.system.to.ensure.proper.
grounding.is.maintained.
Mechanical
• Do.not.use.petroleum.based.lubricants.such.as.vaseline,.
oils,.or.hydrocarbon.based.lubricants..Use.only.100%.
silicone.lubricants.
• All.plastic.connections.should.be.hand.tightened..Plumber..
tape.should.be.used.on.connections.that.do.not.use.an.
O-ring.seal..Do.not.use.pliers.or.pipe.wrenches.
• All.plumbing.must.be.completed.according.to.local.codes.
• Soldering.of.the.plumbing.should.be.done.before.
connecting.to.the.valve..Excessive.heat.will.cause.interior.
damage.to.the.valve.
• Observe.drain.line.requirements.
• Do.not.use.lead-based.solder.for.sweat.solder.connections.
• The.drain.line.must.be.a.minimum.of.1/2-inch.diameter..Use.
3/4-inch.pipe.if.the.pipe.length.is.greater.than.
20.feet.(6.m).
• Do.not.support.the.weight.of.the.system.on.the.control.
valve.fittings,.plumbing,.or.the.bypass.
• It.is.not.recommended.to.use.sealants.on.the.threads..Use.
plumber.tape.on.all.NPT.threads.
General
• Observe.all.warnings.that.appear.in.this.manual.
• This.system.is.not.intended.to.be.used.for.treating.water.
that.is.microbiologically.unsafe.or.of.unknown.quality.
without.adequate.disinfection.before.or.after.the.system.
• Keep.the.unit.in.the.upright.position..Do.not.turn.on.side,..
upside.down,.or.drop..Turning.the.tank.upside.down.will.
cause.media.to.enter.the.valve.
• Operating.ambient.temperature.is.between.34°F.(1°C).and.
120°F.(49°C).
• Operating.water.temperature.is.between.35°F.(1°F).and.
100°F.(38°C).
• Working.water.pressure.range.is.20.to.125.psi.
(1.38.to.8.61.bar)..In.Canada.the.acceptable.working.water.
pressure.range.is.20.to.100.psi.(1.38.to.6.89.bar).
• Use.only.salts.designed.for.water.softening..Acceptable.salt.
type.is.sodium.chloride.pellet.salt.
• Follow.state.and.local.codes.for.water.testing..Do.not.use.
water.that.is.microbiologically.unsafe.or.of.unknown.quality.
• When.filling.media.tank,.do.not.open.water.valve.
completely..Fill.tank.slowly.to.prevent.media.from.exiting.
the.tank.
• Always.make.modifications.to.house.plumbing.first..
Connect.to.valve.last.
• Plastic.parts.and.O-rings.may.be.damaged.by.heat.and.
solvents..When.constructing.plumbing.connections.allow.
heated.parts.to.cool.and.protect.parts.from.solvents.
System Recharge Cycles
Service.(Downflow):
Untreated.water.is.directed.down.through.the.resin.bed.and.up.
through.the.riser.tube..The.hardness.ions.attach.themselves.
to.the.resin.and.are.removed.from.the.water..The.water.is.
conditioned.as.it.passes.through.the.resin.bed.
When.a.recharge.cycle.starts,.the.softener.goes.through.
five.cycles..During.the.recharge.cycle.the.softener.will.allow.
untreated.water.to.bypass.into.the.building.
1.. Backwash.1.(Upflow):
The.flow.of.water.is.reversed.by.the.control.valve.and.
directed.down.the.riser.tube.and.up.through.the.resin.bed..
During.the.backwash.cycle,.the.bed.is.expanded.and.debris.is.
flushed.to.the.drain.
2.. Brine.Draw.(Downflow):
The.brine.draw.cycle.takes.place.during.the.slow.rinse.cycle..
The.control.directs.water.through.the.brine.injector.and.brine.
is.drawn.from.the.salt.tank..Brine.draw.is.completed.when.the.
air.check.in.the.salt.tank.closes.
Slow.Rinse.(Downflow):
The.brine.is.directed.down.through.the.resin.bed.and.up.
through.the.riser.tube.to.the.drain..The.hardness.ions.are.
displaced.by.sodium.ions.and.are.sent.to.the.drain..The.resin.
is.recharged.during.the.brine.cycle.
3.. Repressurize.Cycle.(Hard.Water.Bypass.Flapper.Open):
This.cycle.closes.the.flappers.for.a.short.time.to.allow.the.
air.and.water.to.hydraulically.balance.in.the.valve.before.
continuing.the.recharge.
4.. Fast.Rinse.1.(Downflow):
The.control.directs.water.down.through.the.resin.bed.and.
up.through.the.riser.tube.to.the.drain..Any.remaining.brine.
residual.is.rinsed.from.the.resin.bed.
5.. Brine.Refill:
Water.is.directed.to.the.salt.tank.at.a.controlled.rate,.to.
create.brine.for.the.next.recharge.
Location Selection
Location.of.a.water.treatment.system.is.important..The.following.
conditions.are.required:
• Level.platform.or.floor.
• Ambient.temperatures.over.34°F.(1°C).and.below.
120°F.(49°C).
• Water.pressure.below.125.psi.(8.61.bar).and.above.
20.psi.(1.4.bar).
• In.Canada.the.water.pressure.must.be.below.100.psi.
(6.89.bar).
• Constant.electrical.supply.to.operate.the.controller.
• Total.minimum.pipe.run.to.water.heater.of.ten.feet.(three.
meters).to.prevent.backup.of.hot.water.into.system.
• Local.drain.or.tub.for.discharge.as.close.as.possible.
• Water.line.connections.with.shutoff.or.bypass.valves.
• Must.meet.any.local.and.state.codes.for.site.of.installation.
• Valve.is.designed.for.minor.plumbing.misalignments..Do.not.
support.weight.of.system.on.the.plumbing.
• Be.sure.all.soldered.pipes.are.fully.cooled.before.attaching.
plastic.valve.to.the.plumbing.
• Room.to.access.equipment.for.maintenance.and.adding.
salt.to.tank.
