STARTING UP
Filling the domestic hot water circuit
For.domestic.water.use,.fill.the.accumulator.with.cold.water.and.remove.the.air.from.the.tank.by.opening.a.valve.to.decant.the.hot.water..As.
soon.as.water.starts.running.out.of.the.hot.water.valve,.close.it.
Only.a.qualified.technician.is.authorised.to.start.up.the.unit.
Cleaning the appliance
Before.filling.the.appliance,.clean.the.tubes.to.remove.any.residue.from.production.and.assembly.
Even.small.quantities.of.foreign.matter.can.act.as.a.catalyst.and.cause.decomposition.of.the.heat.transfer.fluid.
Flush.the.appliance.thoroughly.to.remove.any.residue.
Drain.the.appliance.completely.
ADVICE FOR INSTALLATION WITH SOLAR SENSORS
Filling and flushing the solar section
The.appliance.must.only.be.filled.and.commissioned.if.a.heat.extractor.is.used.
•.Open.all.the.stop.and.purge.devices;.in.particular.all.the.purge.devices.on.the.sensor.hydraulic.connections.
•..Operating.with.just.water.in.the.solar.circuit.is.not.permitted,.even.in.areas.not.at.risk.of.freezing.(no.protection.. against.corrosion).
•..The.heat.transfer.fluid.is.a.propylene.glycol.mix,.which.is.non-toxic.and.not.physiologically.harmful.
•..Respect.the.instructions.given.in.the.safety.sheet.
•. Fill. the. appliance. with. heat. transfer. fluid. using. a. pump. via. the. filler. valve;. close. the. stop. and. purge. devi-.
. ces. as. soon. as. fluid. comes. out.. Collect. the. fluid. from. the. drainage. valve. in. a. separate. container. until. the. heat. trans-.
. fer. fluid. comes. out. to. remove. any. water. remaining. in. the. sensors. from. the. appliance.. Stop. the. filling. process..
. and.connect.the.drainage.valve.to.the.pump.
•..Circulate.the.fluid.at.a.pressure.of.3.5.bar.for..hours.until.purging.is.complete.
•..Before.finishing.the.filling.procedure,.adjust.the.pressure.of.the.appliance.and.slowly.close.the.valve.
Pressure of the solar section
The.pressure.of.the.appliance.depends.on.the.height.of.the.system.and.the.pressure.at.the.expansion.chamber.inlet.
•.Check.the.pressure.and,.if.necessary,.open.the.valves.and.adjust.the.pressure.again;.once.the.filling.pressure.is.reached,.close.the.filler/drain.
. valve.
•.Check.that.there.is.absolutely.no.air.in.the.appliance.by.activating.the.manual.deaerator.at.the.highest.point.on.the.appliance..If.necessary,.
. repeat.the.flushing.operation.
•.If.a.purge.device.with.a.duct.and.connection.is.used,.please.be.aware.that.a.quantity.of.fluid.at.least.equal.to.the.volume.of.the.small.venting.
. tube.must.be.evacuated:.0.3.cl.per.metre.for.a.tube.diameter.of.6.mm.
Commissioning the solar pump and solar regulator
When.doing.so,.observe.the.related.instructions.for.use.
•.Check.the.plausibility.of.the.temperatures.displayed.during.commissioning,
•.Check.the.operation.of.the.pump.and.the.regulator.at.the.solar.circuit,
•.Programme.the.regulator,.the.pump.and.the.flow.limiter,.where.applicable,.as.per.the.appliance's.hydraulic.diagram.
Adjusting the flow
The.flow.must.be.programmed.based.on.the.dimensions.of.the.collector.area.and.the.type.of.connection..The.reference.surface.in.this.case.is.
the.surface.of.the.absorber.
Important :
-.The.unit.must.never.be.turned.on.when.it.is.empty,.as.this.risks.damaging.its.electrical.components,.if.using.an.optional.electrics.kit.
-..Check.that.the.various.seals.are.tight..If.necessary,.retighten.the.bolts.(recommended.7.to.10.Nm.–.torque.spanner).or.the.connec-.
. tions.
-.Never.block.the.safety.assembly.opening..
