PROTECH
The.PROFESSIONAL.TECH.system,.an.exclusive.solution,.is.an.electronic.system.which.protects.against.corrosion.and.ensures.the.maximum.life.
of.your.water.heating.tank,.even.where.water.quality.is.poor.
The.electronic.circuit.allows.a.difference.in.potential.to.be.created.between.the.tank.and.the.titanium.electrode,.in.such.a.way.as.to.guarantee.
optimum.protection.of.the.tank.and.prevent.corrosion.
Optimum.functioning.of.the.protection.system.REQUIRES.A.PERMANENT.CONNECTION.TO.A.30V.SUPPLY,.even.when.the.hot.water.generator.
is.not.running..To.be.able.to.disconnect.the.protection.system.for.longer.than..hours.without.risking.the.length.of.the.tank's.useful.life,.it.is.
essential.to.drain.the.tank.beforehand!.!!
The.electronic.circuit.is.linked.to.the.30V.network,.and.also.to.the.tank.being.protected.and.the.titanium.protection.electrode,.as.shown.in.
the.diagram.on.the.following.page.
Correct.functioning.of.the.protection.system.is.indicated.by.the.green.indicator.light.coming.on,.which.shows.that.the.circuit.terminals.are.live..
In.case.of.a.fault,.the.red.indicator.light.will.signal.that.there.is.a.short.circuit.between.the.electrode.and.the.tank,.that.one.of.the.cables.(tank.
or.electrode).is.detached,.or.that.there.is.no.water.in.the.tank.
Therefore,.your.hot.water.generator.is.correctly.protected.if.the.green.indicator.light.is.on.and.the.red.light.is.off..If.this.is.not.the.case,.please.
call.your.installer.
Note for the installer
Important:.do.not.carry.out.any.operation.without.having.first.cut.the.electricity.supply.from.the.30V.network,.(as.this.is.a.quick.operation,.it.
can.be.carried.out.without.first.draining.the.tank.and.not.necessarily.cause.corrosion).
The.electronic.circuit.can.be.replaced.very.easily,.without.draining.the.tank,.by:
-.Unplugging.the.two.supply.lines.that.lead.from.the.electronic.circuit.to.the.supply.terminal.block,
-.Unplugging.the.quick.connector.with.polarising.slot.that.links.the.circuit.to.the.tank.and.the.electrode,
-.Detaching.the.electronic.circuit.from.its.support.(plastic.clips.in.the.4.corners),
-.To.replace.a.defective.circuit.with.a.new.one,.perform.the.above.steps.in.reverse.order.
Diagnosing electronic circuit failure
1).The.GREEN.light.is.not.on.:
--.Verify.that.the.circuit.supply.line.is.plugged.in.(if.not,.plug.it.in),
-.Check.that.the.electronic.circuit.is.being.supplied.(if.not,.replace.the.supply.cable),
-.Verify.that.the.power.being.supplied.is.30V.(if.not,.supply.30V),
-.If.all.the.above.have.been.verified.and.there.is.still.a.fault,.replace.the.electronic.circuit.(installer).
).The.RED.light.is.on.:
-.Verify.that.the.tank.is.full.of.water.(if.not,.fill.it.so.that.the.following.checks.can.be.carried.out),
-.Verify.that.the.quick.connector.is.properly.positioned.(if.not,.correct.this),
-.Verify.that.the.electrode.connection.cable.(that.enters.the.glove.finger.in.the.base).is.properly.connected.(pull.it
. gently.from.above.to.make.sure.it.is.connected).(if.not,.replace.the.base.and.its.electrode),
-.Verify.that.the.tank.connection.cable.is.properly.connected.to.the.tank.(if.not,.connect.it.correctly),
-.Verify.that.the.two.cables.coming.from.the.quick.connector.are.not.damaged.or.stripped,.etc..(if.they.are,.replace.the.base.and
its.electrode),
-.If.all.the.above.have.been.verified.and.there.is.still.a.fault,.replace.the.electronic.circuit.(installer).
Request.the.assistance.of.your.installer.
