GENERAL INFORMATION

Read carefully all the instructions for assembly and for rst activation. Assembly and rst activation must be carried out

only by authorised installers. The guarantee shall not be valid if the indications of Pleion are not followed.

Installation must be carried out only by qualied personnel and in full respect of safety regulations and of the indications

contained in this document. We recommend that only original components, specically designed for the series of solar

thermal vacuum panels, be used.

Before the installation and start-up of the system, knowledge of the standards, laws and provisions of the locality in

which the systems are situated must be obtained. Suitable belts should be used to transport the solar panels. Do not lift

the solar panels using the threaded hydraulic connections. Do not allow the solar panels to sustain blows or mechanical

action; special care must be paid to protect the glass tubes which, for their nature, can be shattered.

STATIC

Solar collectors must be installed on a sufciently sturdy surface. Static capacity must be checked by a structural engineer

prior to any installation. Check suitability for xing systems. For installation in particularly snowy and/or windy sites

please contact manufacturer.

LIGHTNING PROTECTION / EQUIPOTENTIAL BONDING OF THE BUILDING

In accordance with the lightning protection standard ÖVE/ÖNORM EN 62305 Part 1-4 the collector array cannot be

connected to the building’s lightning protection. A safety distance of at least 1 m must be maintained from any possible

adjacent conducting object.

For installations on metal substructures at the installation site, qualied electricians must be consulted.

To carry out a building potential equalization, the metal tubes of the solar circuit and all collector cases or fastenings

must be connected to the main potential equalization bus by a qualied electrician in accordance with ÖVE/ÖNORM E

8001-1 or the country-specic standards.

CONNECTIONS

Connect the collectors together with the exible connectors supplied which regulate any linear thermal expansion in the

pipes and collector. Irreparable damage may occur if such connectors are not used.

COLLETTOR ANGLE / GENERAL NOTES

The solar collector and xing systems have been designed for angles between 15° and 70°. Please contact manufacturer

for authorization under different installation conditions.

COVER THE PANELS

During installation, it is essential to cover the area of the panels that is sensitive to sunlight, immediately and during

the entire preparation of the system. The panels must remain covered also during the successive loading and start-up

steps; they will be uncovered by the installer only when said steps have been completed. The solar panels, if left empty

and under the rays of the sun, in any season and condition, can undergo irremediable damage not ascribable to the

products but to said exposure.

FLUSHING AND FILLING

Flushing and lling must be carried out only when the collectors are covered (see the paragraph “Covering the

collectors” above). Fill the collectors with anti-freeze/water mixture supplied by manufacturer.

Anti-freeze recommended by manufacturer:

After the rst lling the collectors cannot be emptied completely, so to avoid any “risk of freezing” this anti-freeze/water

mixture must be used to test working operations and wet sealing.

Any damage caused by freezing is not covered by warranty.

INSTALLATION OF TEMPERATURE SENSOR

The temperature sensor must be installed in the specic holder on the collector head (hot side) to ensure optimal

contact for accurate readings, sensor holder should be lled with conducting compound. Sensor must be temperature

resistant up to 250°C.

OPERATING PRESSURE

The normal operating pressure is 2-3 bar.

The maximum test pressure is 10 bar.

START UP

SOLAR LIQUID FAST G28

Premixed solar liquid ready for use in solar thermal vacuum

panels, blue in colour based on monopropylene glycol, suitable

for temperatures as low as -28°C. The chemical formula which

includes corrosion inhibitors prevents the corrosion of the

metals with which it comes into contact, and thus protects

metals like aluminium and copper of which the main parts of a

solar system are made.

Insoluble metal oxides, which can develop if the system is not

bled and which cannot be removed, will form mud which over

time can deposit on the heat exchange surfaces thus decreasing

the yield, and therefore the mixture includes additives with a

dispersing action so that any deposits are kept in suspension.

Available in drums of 10 and 20 litres.

In the system installation and loading phase, the solar panels must be transported and handled in their original

packaging, which must not be removed until they are positioned on the roof, or any other structure on which they

are to be installed, in accordance with the paragraph “Cover the panels”.

When handling and lifting the solar panels, personal protective equipment suitable for the handling should always be

worn. The panels should be transported with the aid of ropes passed through the eyebolts provided (see the gure

below). The eyebolts must be screwed to the bolts provided on the rear part of the panel head prole.

It is obligatory to use certied karabiners (spring catches) and ropes that have a breakage point above 2000 kg.

Non sollevare il collettore utilizzando gli attacchi idraulici filettati, non sollevare il collettore gravando

o tirando sui tubi di vetro.

Evitare che il collettore subisca colpi o azioni meccaniche, proteggete soprattutto

i tubi in vetro che per la loro natura sono particolarmente fragili.

Fissare accuratamente le funi per il sollevamento: Attenzione pericolo di incidenti anche gravi!

TRANSPORT INSTRUCTIONS

Do not lift the manifolds by connecting to the threaded hydraulic connections.

Do not lift the collectors by putting on or pulling on the glass tubes.

Prevent collectors from being struck or mechanically damaged, especially protect glass pipes

which by their nature are particularly fragile.

Attach any lifting belts carefully to avoid serious accidents!

DESCRIPTION

The panels with X-RAY R tubes have three main pre-assembled components:

~ Vacuum tubes;

~ Curved CPC mirrors;

~ A collector with a heat distribution unit and integrated return tubing

Each vacuum tube is composed of two concentric glass tubes; every single tube is closed at one end by a hemisphere,

and is connected with another tube at the other end. The vacuum is created in the space between the tubes. The

recipient which is thus formed can be considered a heat recipient. To more effectively store the solar energy, the

internal glass tubes (protected by the hollow space containing the vacuum) are coated with aluminium nitrite, which

allows the tubes to capture the heat very efciently.

Highly reecting CPC (compound parabolic concentrator) mirrors, resistant to atmospheric agents, have been placed

behind the vacuum tubes to further increase their efciency. The geometry of the mirrors allows both direct and

diffused sunlight to hit the captivating surface even when the rays of the sun strike them at an unfavourable angle.

The input and return tubes are located in the upper part of the panels. The input tubes branch into heat absorption

units; these are U shaped copper ducts provided with heat deectors in sheet aluminium, which transfer the heat

from the glass tubes to the U shaped tubes through which the vector liquid ows. The hot liquid ows through the

tubes and reaches the heat exchange unit for the production of hot water for domestic use or to supplement the

central heating system.

The vacuum collectors are supplied completely pre-assembled and therefore they are fast and easy to install.

They are a reference point for the solar market thanks to their physical resistance, energy performance and exclusive

design. The exclusive hydraulics of the X-RAY R collectors with a built-in third tube allow for connecting up to 6 solar

panels in cascade mode, with the extraordinary advantage that an external return line is not required.

This drastically reduces the installation cost and time, and guarantees a hydraulically balanced system with a

clean and elegant line. Installation is possible thanks to the anchorage system which allows for installation on any type

of surface. The third lateral connection allows for integrated hydraulic connection, with parallel hydraulic distribution

which improves the energy performance compared with normal panels connected in series.
