1. Introduction

Lightning protection

In case the height at which the collectors are to be installed exceeds 20 metres

and a building is not equipped with the lightning protection it is necessary to

connect all electrically conducting elements with an earth rod (minimal earth

rod cross-section – 16mm

), and then with a compensating potential.

In case the height at which the collectors are to be installed does not exceed

20 metres it is not necessary to provide the lightning protection.

If the building is equipped with the lightning protection it is important to

check the connection of the solar system to the lightning protection. That task

should be performed by an electrician.

Recycling

Completely used up solar collectors can be returned to the manufacturer.

The returned solar collectors shall be utilized by the manufacturer in the way

which is the least burdensome for the natural environment.

2. Safety during installation

Before commencing the installation work it is necessary to immediately

get acquainted with the safety tips!

2.1. Notes included in the instruction.

The installation instruction includes important information concerning safety

and proper positioning of the collectors on the roof as well as the correct

execution of the hydraulic connection. Drawings and information included in

the instruction apply to a vertical installation of the collectors.

Installation of the collators can only be performed by qualified personnel with

professional experience in the field of water supply and gas systems.

Upon completion of works an installer should hand over the installation

instruction to a customer and clearly explain the principles of operation and

directions essential to a proper operation of the solar system.

2.2Application

This instruction includes a description of an vertical assembly set to carry out

the installation of solar collectors (vertically and horizontally) on the roof

with the inclination ranging from 30

up to 65

The assembly set shall exclusively be used to perform the installation of solar

collectors, it must not be used to install different devices on the roof.

Installation of only solar collectors on the supporting structure guarantees its

safety of operation.

integrated in the slate roof.

3. Before commencing the installation.

Directions!

As the work on the roof can be dangerous it is recommended to hire a

roofwork firm.

DANGER OF GETTING SCALED.

In case the collectors and assembly materials are exposed to solar radiation

for a long time, there is a risk of getting scalded by hot elements.

In order to avoid the danger of scalding you should:

use protective clothing,

cover the collectors and the assembly materials with canvas cover

(thanks to which the heating up by sunbeams will be reduced).

3.1 Transport and storage.

during transport the collector connectors are protected by rubber caps,

collectors should be stored in a dry place. In case the collectors are stored

outside they should be protected against weather conditions.

3.2 Technical Documentation

Solar installation set consists of different components. Before

installing any of the components you should become

familiar with an adequate instruction.

A separate installation instruction is attached to a given device or a piece

equipment.

Installation instruction of solar collectors,

installation instruction of the pump group,

installation instruction of the solar controller,

installation instruction of the hot water container.

3.1 Completeness of delivery

Before commencing the installation it is necessary to check if the delivery is

complete and the delivered components are free of damage.

−in case of discovering any damages the defected elements or parts should

be immediately replaced,

−the replacement needs to be carried out with the application of original

spare parts only.

−the basic set is designed for two solar collectors, extending the solar

instalation for each successive solar collector is associated with

purchase an aditional extension set for each solar collector

3.5 Location of a collector

Potential quantity of the absorbed radiation depends on a proper location of

the absorber in relation to falling sunbeams.

Optimum is a perpendicular position of a collector surface in relation to the

falling solar radiation.

Recommended location of a collector:

inclination angle:

40 – 45

for a year-long installation,

approximately 30

for installations used in summer,

approximately 60

for installations used in winter,

positioning of a collector in the southern direction (or approximate to the

southern direction).

Solar collectors must not be installed at the inclination below 30

over 75

It is recommended to install the collectors on the southern roof slope. During

the installation work particular attention should be paid to protect the

collectors from being overturned by strong winds. Permissible snow

and wind load amounts to max. 2,0 kN/m².

Collectors field should be located in such a way that the absorber will

not be shadowed by the adjacent buildings, trees, etc.

In case of a larger number of collector fields it is important that the front row

of the collectors do not shadow the back one.

3.7 Flow resistance for collectors

3.8 Warranty conditions of the installation and use of the collectors ES2V/2.0 AL

with aluminum absorber

It is allowed to use only solar fluids that is accepted and offered by the producer, e.g.

ENSOLICOL-AL -25,

It is allowed to wash the solar thermal system and perform the leak test only with solar fluid,

The solar thermal system must be closed (hermetic):

−the solar system can not contain automatic vents (potential place through the installation can

get into air),

−before the first start, the solar system must be completely deaerated, and be leakproofed by

the plumber,

−any leaks are associated with getting air into the solar thermal system with maximize the risk

of corrosion. Once air get into the solar system the solar fluid must be replaced.

It is allowed to use only connections systems that are offered by the producer,

It is recommended to do the solar system with flexible stainless steel tubes or steel tubes. It

is forbidden to connect directly the connector pipe of the collector witch any copper or brass

parts of the solar system witch increases the possibility of electrochemical corrosion.
