INSTALLATION OF THE SOLAR COLLECTORS
SOLAR COLLECTORS
To.ensure.optimal.yield,.the.solar.collector.must.face.southwards.
We.recommend.installing.a.minimum.of.2.collectors.for.every.DB.solar.hydraulic.unit.
A.15-20.°C.deviation.can.be.accepted;.deviations.that.exceed.20°.must.be.compensated.by.using.a.larger.collector.
In.Italy,.for.example,.for.annual.use,.a.support.inclined.by.45°.is.used.(eg.for.civil.use).
We.recommend.covering.the.collectors.until.the.system.is.commissioned,.in.order.to.prevent.damage.to.the.insula-
tion,.due.to.the.high.temperature.that.can.be.reached.(up.to.200.°C),.and.during.prolonged.downtime.
Use.the.packaging.of.the.collectors.to.cover.the.solar.panels.or,.alternatively,.use.shading.sheets.
When you fasten the fittings to the solar collector, block the terminal box using a wrench (or clamp) to oppose a
counter force and prevent torsions in the head of the panel pipe bundle.
BREAKAGE.DUE.TO.THE.TORSION.OF.THE.PIPE.BUNDLE.IS.NOT.COVERED.BY.THE.WARRANTY.
We.also.recommend.moving.the.water.(from.top.to.bottom).inside.the.collectors.and.boiler.heat.exchangers.before.
installation.in.order.to.remove.any.processing.waste.
CONNECTION JOINTS AND FITTINGS
To.join.the.threads.of.the.primary.circuit,.especially.those.located.externally,.we.recommend.using.anaerobic.seal-
ant.that.resists.temperatures.higher.than.150°C.or,.alternatively,.use.hemp.(for.a.mechanical.seal).combined.with.
high.density.Teflon.for.vapour.(for.hydraulic.seal).
The.copper.pipe.junctions.of.the.primary.circuit.must.be.made.with.brazing.or.mechanical.brass.fittings.with.metal.
warhead.seal..Avoid.fittings.with.O-ring.seal,.as,.at.high.temperatures,.this.material.may.cause.damage.(unless.
O-rings.are.used.for.special.solar.systems).
The.junctions.of.stainless.steel.piping.must.be.flared.with.fittings.and.have.a.gasket.suitable.for.high.temperatures.
and.be.supplied.with.a.specific.kit.
Use.bronze.or.brass.fittings.in.contact.with.the.panel.to.prevent.corrosion.due.to.galvanic.currents.
Example.of.installation.of.solar.collector.fittings...
Refer.to.the.instructions.provided.in.the.installation.diagram.attached.to.the.material.required.to.see.how.to.mount.
the.solar.panel.fittings.
ATTENTION:
The cold inlet of the "Sime Plano" collectors must be located at the bottom right or at the bottom left of the col-
lector coil.
The hot outlet must be at the top of the opposite side, ie, if we enter in the bottom left, we must exit from the top
right and vice-versa (see Fig. 14).
