CHECKING THE SEAL
Complete.the.rinsing.phase.by.closing.the.tap.(B).and.let.the.pressure.increase.inside.the.solar.system.until.
a.pressure.0.2.bar.below.that.of.the.safety.valve.is.reached.(eg,.if.the.safety.valve.is.6.bar,.try.with.5.8.bar)..
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).
THE WARRANTY DOES NOT COVER ANY ICE BREAKAGE
The.cold.water.filling.pressure.in.the.solar.collector.must.be.of.1.2.-.1.5.bar..If.the.system.filling.point.meets.the.thermal.
system,.it.is.necessary.to.reach.the.pressure.resulting.from.the.difference.in.hydrostatic.level.between.the.thermal.sys-
tem.and.the.solar.collector...For.example,.in.the.event.that.the.set.of.collectors.is.open.at.a.height.close.to.6.m.compared.
to.the.thermal.system,.which.is.6.m.=.0.6.bar,.the.system.should.be.charged.by.2.1.bar.(1.5.bar.+.0.6.bar).
The.filling.occurs.as.described.below:
