FORCED CIRCULATION SYSTEMS Nowadays,.production.and.energy.savings.without.contaminating.the.environment.is.extremely.important..The.conven- tional.energy.sources.of.the.planet.are.declining.to.a.threatening.level,.as.our.society.requires.an.increasing.amount.of. energy;.as.a.result,.pollution.is.affecting.the.climate.balance. On.the.other.hand,.the.Renewable.Energy.Sources.can.be.a.solution.for.both.the.energy.and.environmental.problem..The. international.legislation.is.gradually.modifying.and.encouraging,.even.imposing,.the.use.of.alternative.energy.products. with.the.aim.of.meeting.the.energy.requirement.without.placing.the.environment.at.risk.

A.family.made.up.of.four.people.with.an.average.DHW.consumption.of.40.litres.per.person,.requires.a.160-litre.solar. system...The.requirement.increases.by.at.least.40.litres.per.day.if.we.add.the.domestic.appliances.connected.to.the.solar. system..To.obtain.the.maximum.benefit.from.the.solar.water.heater,.use.the.highest.amount.of.hot.water.possible.during. the.day.so.that.the.plant.can.continuously.produce.during.the.sunny.period,.maintaining.yield.to.a.maximum.

Close.the.tap.(A).and.then.the.water.tap. Open.the.shut-off.tap.(v)..Configure.the.solar.circuit.pump.operation.in.the.control.unit,.open.the.shut-off.taps. of.the.bleed.valves.and.release.the.air.from.the.solar.circuit.manually: –..on.the.roof,.remove.the.cover.of.the.bleed.valve.and.and.press.using.the.tip.of.a.screwdriver; –..on.the.thermal.system,.through.the.exhaust.gas.of.the.solar.unit. Check.the.pressure.and,.if.required,.reset.by.opening.the.tap.(A).and.the.water.tap. visually.check.all.the.pipes.and.fittings.and.make.sure.there.are.no.leaks..Leave.the.system.under.pressure. for.a.time.to.verify.whether.the.pressure.decreases. During.a.trial.period,.the.system.can.run.only.with.water.to.verify.the.presence.of.possible.leaks,.if.there.is. not.risk.of.frost. New.systems.may.freeze.because.the.owner.bought.the.antifreeze.liquid.but.did.not.add.it.the.system..To. avoid.these.problems,.make.sure.that.the.antifreeze.liquid.has.been.poured.into.the.system. BLEEDING THE SOLAR CIRCUIT Connect.both.taps.to.a.cube.using.a.rubber.pipe.to.discharge.and.drain.the.system..The.amount.of.water.can. be.measured.and.used.to.prepare.the.mixture.of.water.and.glycol..To.ensure.drainage,.the.bleeding.valves. must.be.open.to.make.the.air.enter.and,.if.required,.press.using.the.screwdriver.to.facilitate.the.operation. Make.sure.that.the.water.filled.in.the.circuit.is.discharged.from.the.system.to.prevent.it.from.freezing.or.from. damaging.the.panel. FILLING THE SOLAR CIRCUIT Before.filling.the.circuit,.check.the.pre-charge.pressure.of.the.expansion.vessel.using.a.pressure.gauge.or. bike.pump.having.a.pressure.approximately.0.3.bar.below.the.cold.water.filling.pressure.of.the.system. If.you.plan.to.use.the.antifreeze.liquid,.mix.water.and.glycol.inside.a.container.before.pouring.it.into.the.sys- tem..The.percentage.of.glycol.depends.on.the.minimum.temperature.that.can.be.reached.in.the.area.where. the.system.is.installed.(it.is.obtained.from.the.stored.data.related.to.the.minimum.temperature.of.the.area).. This.temperature.must.be.reduced.by.at.least.10°C.so.as.to.allow.the.panel.to.cool.down.to.about..6-7°C.above. ambient.temperature. To be sure, integrate the antifreeze liquid until you reach 40% of the volume of the total mixture (not lower, regardless of the protection rating, to achieve an effective inhibitory function against pipe corrosion).
