recommendations:

gross area copper tube corrugated stainless-

steel tube

Do 10 m2 18mm DN16

Do 22 m2 22mm DN20

Od 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

profiles with the mounting screws (6)

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.

reinforcing sleeve

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 SB-1800/58-22 oraz SB-1800/58-30 collector the middle support profile is centered in

accordance with the location of the tile holes.

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 SB-1800/58-30 collector the middle support

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.

To mount collector SB-1800/58-18 and SB-1800/58-22 it is required to assembly 2 supporting

triangles. Collector SB-1800/58-30 is mounted on supporting construction made of 3

triangles.

After fixing together all elements of supporting triangle, it is necessary to mound side profiles

to supporting triangle as on the photo below.

5. 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.

6.4 Option for mounting an automatic air escape. If there is not any space for an automatic air escape a manual air escape

should be installed.

7 – adapter ¾ '' x 3/8 ''

8 – ball valve 3/8 ''

9 – automatic air escape 3/8 ''_

- unscrew the manual air escape from

the top of the pipe-cross (5),

- successively screw the adapter (7),

valve (8) and automatic air escape

(9) at the top of the pipe-cross.

Directions!

Due to high temperatures in the solar systems it is necessary to use

air escapes made completely of metal.

6.5 Connection of the temperature sensor

Damage to the system

In case of wrong installation of a temperature sensor or damage to

the signal cable there is a risk of damage to the system.

- signal cable must be protected against damage (e.g. damage caused by

birds, rodents) using a protective coat.

Temperature sensor should be installed

in an immersion sleeve.

− insert the temperature sensor into

the immersion sleeve,

− protect with a clamping spring against

moving out.

6.6 Connection of collecting conduits

Hydraulic connection with collecting pipes should be executed by means of

an insulated flexible conduit. It is not allowed to connect stiff collective

pipes directly to the collector.

The connection of flexible conduits with the system must be done below the

level of the air escape.

Directions!

Universal roof ventilators and antenna penetration should be used to execute

the passage of conduits across the roof.

Directions!

A cable for the temperature sensor should be laid together with the flexible

return conduit.

7. Finishing work

7.1 Inspection of the installation

Upon completion of the installation work it is necessary to:

− inspect the installation correctness of all elements of the system,

− check the system by means of a pressure test,

− flush the system with water,

− fill in the system with the solar agent.

After the pressure test and water flushing of the system it must be immediately filled

up with the solar agent. Otherwise, the tightness test and flushing need to be carried

out directly before filling up the installation with the solar agent.

7.2 Insulation work

Insulation work should be done after performing all inspection operations.

Directions!

− High temperature and weather resistant insulation must be used to insulate

the conduits which are outside the building.

If necessary, protect the insulation against damage caused by birds.

− High temperature resistant insulation must be used to insulate the conduits

inside the building.

8. Maintenance and Service

During the maintenance and other kind of work a collector must be placed firmly

to exclude the danger of tripping over and falling down,

It is not allowed to perform any repair and maintenance work under a lifted

collector which has not been protected against casual falling down.

- Repair and maintenance work should be done by means of suitable tools and the

servicing personnel should wear protective gloves and shoes,.

- Overhaul of the solar system needs to be done in accordance with warranty

recommendations for particular elements of the system.

In order to guarantee failure-free operation of the whole system it is

recommended to carry out the following maintenance work at least once a Year

The control and protection system should also be inspected along with the

structure for supporting and fixing a collector on the roof.

In order to guarantee the proper operation of the whole system, every time we

recommend you to enter into a contract for maintenance work with a specialist.
