Up to 10 m2 18mm DN16

Up to 22 m2 22mm DN20

Up to 23 m2 28mm DN25

Connecting the tubes with the collector:

- clamping connection (recommended)

Corrugated stainless-steel tube ( INOFLEX) with insulation:

- simple installation with high temperature sealing fittings.

The tube and the insulation has to show the following characteristics:

- momentary temperature durability over 150°C (e.g. caoutchouc or mineral wool)

- insulation thickness is the diameter of the pipe (based on the heat transfer coefficient

K= 0,04 W/mk)

1.2 Electrical installation, lightning-rod and grounding

The electrical installation should be done by a specialist, in accordance with all current

requirements and standards. In order to compensate potentials all metal parts of the solar

installation should be installed on the main bus, in accordance with electrical regulations. If

the building has a lightning installation, it should be connected to the collectors.

1.3 Safety during installation

ATTENTION !!

Vacuum panels should be covered up during the installation to the moment of filling up

and venting the installation, or the assembly of the vacuum pipes should be done after

the filling up and venting the installation. It is not allowed to fill up the solar installation

when the collector is under direct sunlight. In the solar installation may occur temperatures

above 100°C, which during filling up can cause damage to the installation (this damages are

not covered by the warranty).

To protect the solar installation against freezing you should fill up the installation with an

suitable solar fluid that protects the installation against corrosion and freezing.

Recommended flow of solar fluid: 0.7 L / min per m2 of the absorber surface.

The temperature difference between the supply and return of the installation should be max

10°C.

2. Installation of a collector

To each vacuum collectors set there is a suitable mounting set attached. Each set is adjusted to

a proper installation of the collectors on the flat roof or foundation, inclined tile roof or

roofing made of sheet, tar paper, bituminous shingle or metal tiling. Each collector is mounted

separately.

2.1 Completeness of delivery

2.2 Collector with 18-22 pipes with the mounting system adapted to the inclined roofing:

1. manifold – 1 pcs

2. bottom supporting frame – 1 pcs

3. side mounting profiles – 2 pcs

4. vacuum pipes support – 18 or 22 pcs

5. set of mounting screws - 1 set

6. heat transfer paste – 1 pc

7. heat pipes - 18 pcs. (SP-18), 22 pcs. (SP-22)

5

2.3 Collector with 30 pipes with the mounting system adapted to the inclined roofing:

1. manifold – 1 pcs.

2. bottom supporting frame – 1 pcs.

3. side mounting profiles – 3 pcs.

4. vacuum pipes support – 30 pcs.

5. set of mounting screws - 1 set

6. heat transfer paste – 1 pc.

7. heat pipes - 30 pcs.

3. Installation scheme

middle profile No. 3 applies only to the mounting set for collectors SP-58 30

The manifold (1) and the bottom supporting frame are mounted to the side mounting

profiles with the mounting screws (6)

8

4. Installation on the inclined tile roof

The collector should be fixed with the roof hooks, that can be attached directly to the side

mounting profiles.

To determine the spacing between the roof hooks, you should use the side mounting profiles

(3) and the bottom supporting frame.

Side spacing is determined by the location of the tile holes.

In the SP-30 collector the middle support profile is centered in accordance with the location of

the tile holes.

5. Installation on the inclined roof with roofing made of sheet,

tar paper, bituminous shingle or metal tiling.

The collector should be fixed with the roof screws, that can be attached directly to the side

mounting profiles.

To determine the spacing between the roof screws, you should use the side mounting profiles

(3) and the bottom supporting frame (2). In the SP-30 collector the middle support profile is

centered in accordance with the location of the tile holes.

12

6. Installation on a flat roof or foundation.

Supporting triangles are the base of the assembly set. All triangles are assembled in the same

way. Before commencing the assembly of a supporting triangle you should lay out all its

components according to the figure presented below.

After planning out the location of all the components you can start bolting together an

assembly triangle.

13

Two supporting triangles are needed for the

collectors SP-18 and SP-22. The collector

SP-30 needs 3 supporting triangles

After bolting the supporting triangles you should fix the side mounting profiles to the

supporting triangle, as shown in the picture below.

14

7. Installation of the vacuum pipes

After the assembly of the supporting construction you can begin the installation of the heat

pipes. First attach the heat pipe supports.

Before installation, be sure to apply heat transfer paste on the end of the heat pipe

After inserting the heat pipes to the manifold you should lay out and close them in the bottom

vacuum pipes support. Repeat until all the heat pipes are mounted.

8. Safety regulations

Before installation, read the following instructions to ensure trouble-free and safe of the

collectors. Please read instructions carefully and follow the safety rules. Before installing the

pipes and warming them up, the collectors must be hydraulically connected to a solar

heating system and must be filled up with the heating medium.

8.1 Work on the roof

Due to the fact that the assembly work on the roof can be dangerous, it is recommended to

hire a roofing company.

- collector pipes are made of glass, so you should pay special attention to possible breakdown

of the pipe

- during the assembly of the collector you should wear eye protection and gloves to avoid

possible injuries

- follow the safety rules and regulations relating to the execution of work at heights.

8.2 Risk of getting burned

If the collectors and materials for installation are for a long time exposed to sunlight, there is a

risk of getting burned by hot components.

In order to avoid danger of getting burned you should:

- use protective clothing,

- cover the collector and the mounting material with a curtain (reduction of a heat from

sunlight).

8.3 Filling up the installation

For filling up and washing the solar system, we recommend the use of a mobile filling station

with a flow of the solarfluid of 52 l/min. Recommended minimum pressure in the solar

system 2.2 bar.
