Installation
i
nstruction
for flat collectors on flat roof or foundation.
1. Introduction
Lightning protection installation
In the case where the height of the collector installation exceeds 20m and the building is not
e uipped with lightning protection, all of the electrically conductive elements should be
connected to an earth rod (minimal earth rod cross-section – 16mm
2
), and then to the
e ualizing potential.
When the collector installation height does not exceed 20m, the lightning protection system
is not re uired.
If the building is e uipped with the lightning protection, the connection of the solar
installation with the lightning protection should be checked. This procedure should be
performed by an electrician.
Recycling
Worn out solar collectors can be returned to the manufacturer.
The manufacturer will dispose the returned collectors in an environmentally sound manner.
2. afety during installation
Before starting the installation it is necessary to get promptly acquainted with the
safety precautions!
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 proper execution of the hydraulic
connection.
The drawings and the information included in the instruction apply to a vertical and
horizontal installation of collectors.
The installation of collectors described in the instruction may only be performed by
ualified persons who have expertise in a range of gas and water installations.
Upon the completion of works, the installer should hand over the installation instruction to
the customer and present in a comprehensible manner the principles of operation and Note
essential to a proper operation of the solar installation.
2.2 Application
This instruction includes a description of an installation set for installation of collectors on a
flat roof or a foundation with the inclination ranging from 30° to 75°.
The installation set shall be used only for solar collectors installation, it must not be used
for installation of other devices on the roof. The installation of solar collectors only on a
supporting structure guarantees safety.
Collectors installed on the ground must be attached to the ground by the means of
foundation and transitional construction (Not included in the standard installation set).
The minimum distance between the bottom edge of a collector to the ground surface must
be min.40cm.

3. Before installation
Note
Due to the fact, that installation works on a roof can be dangerous it is recommended to hire
a roofing contractor company to carry them out.
BURN HAZARD
If collectors and installation materials are exposed to solar radiation for a long time, there is
a risk of getting burnt on the hot elements.
In order to avoid the danger of getting burnt it is appropriate to:
- use protective clothing,
- cover the collectors and installation elements with a tarpaulin (what limits the heat up
from the sun rays).
Caution!
If the collectors are packed on a transport pallet vertically,
use the following unloading instructions.
Read the instruction before proceeding to unloading of the vertical collector pallet!
1) The first stage before unloading is to set the transport pallet on a flat surface. Figure 1.1 shows the transport
pallet set on a flat consolidated foundation
2) The second stage of unloading is to put a 30mm high board under the transport pallet so that the inclined
transport pallet becomes stable. Figure 2.1 presents the conditions that the transport pallet should fulfill
before unloading.
3) After fulfilling the conditions for setting the transport pallet, the collectors can be unloaded. Take special
caution while unloading (COLLECTOR ARE PROTECTED ONLY AT THE FRONT OF THE
PALLET). In the picture marked as 3.1, the transport pallet ready for unloading is presented.
4) After removing a collector, the next one should be absolutely protected until it is unloaded.

3.1 The delivery completeness
Before installation it is necessary to check if the delivery is complete (see figure below) and
the delivered components are not damaged.
- in case of discovering any damages of element or part the replacement of a such should
be immediately provided,
- the replacement must be provided only with the application of original spare parts

3.2 hipment and storage
- during shipment the collector connectors are protected by rubber caps,
- the collectors should be stored in a dry place. If the collectors are stored outside they
should be protected from atmospheric agents.
3.3 Technical documentation
Solar installation set consists of different components. Before installing any of them you
should become familiar with an ade uate instruction. Installation instructions are attached
to a given device or piece of e uipment.
- installation instruction for solar collectors,
- installation instruction for a pump group,
- installation instruction for a solar controller,
- installation instruction hot water tank.
3.4 Tools and additional equipment
- level gauge,
- harness with a safety cable (for work at heights),
- scaffolding, a roof ladder or a crane.
3.5 Collector location
Potential uantity of the absorber radiation depends on a proper location of the absorber in
relations to incident rays. Collector surface horizontal position to radiation is an optimum
manner.
Recommended location of a collector:
- inclination angle:
40 – 45
o
for yearlong installations
approx. 30
o
for installations used during summer

- positioning of a collector in the southern direction (or approximate to the southern direction).
Collectors recommended, optimal angle of inclination ranges from 30° to 75°.
The admissible inclination angle of collectors ranges from 15° to 90°. It is recommended to
install collectors on a south-facing roofs. During installation, particular attention should be paid
to protection of the collectors against strong winds.
The admissible snow and wind load amount is max. 2,0 kN/m².
A collector field should be located in a manner 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 for the front row not to shadow the
one in the back.
3.6 The warranty conditions of installation and use of collectors can be found in the
warranty card of a particular collector.
3.7 Application of collectors in coastal areas.
For collectors that are installed up to 500LM from the coastline – lack of warranty for an
absorber with a high-selective coat.
It is recommended to apply collectors with an absorber with an increased resistance to
seawater e.g. Mirosol TS.

4.1 Inclination angle of the collectors
4.1.1 Roof or flat surface
In case of collector installation on a roof or a flat surface, the inclination angle of an
installing system corresponds directly to the assumed inclination of collectors.
4.1.2 Roof or surface of inclination angle up to 20°
In case of roofs inclined in the
southern direction „A” the roof
inclination should be deducted from
the assumed collector inclination. In
case of roofs inclined in the northern
direction „B”, the roof inclination
should be added to the assumed
collector inclination.
The obtained value indicates the
inclination angle of the set.

Inclination angle of an installation set can be adjusted by cutting the profile in a proper,
marked spot. Standard angles of inclination were set at 30, 45 and 60°.
When it is necessary to set the installation set in a different angle one should make
connection holes oneself, bearing in mind the maximum setting of the solar collector angle
in the range of 15 - 60°.
4.2.2 etting the inclination angle of an installation set for a vertical collector
Inclination angle of an installation set can be adjusted
by means of telescopic rails. Standard inclination
angles have been determined as 30, 45 and 60°
depending on the position of the installation set. In
order to obtain the assumed inclination angle, it is
necessary to connect properly the sections of the
installation set.

The supporting triangles are the base of the installation set. All of the triangles are
assembled in the same manner.
Note!
Before a supporting triangle assembly all of the components should be laid out
according to the figure presented below.
When of all the components are arranged, the assembly triangle can be bolted together,
bearing in mind the setting of a suitable inclination angle (4.2 Determining the inclination
