must only work on units if they have the re-
quired qualification.
When working on the units, the competent persons must
observe all applicable directives, standards, laws and other
regulations.
2.3 General safety information
2.3.1 Danger due to improper use
Vaillant auroTHERM VTK tube collectors are constructed
using state-of-the-art technology in accordance with the re-
cognised safety rules and regulations. Nevertheless, there
is still a risk of injury or death to the user or others or of
damage to the unit and other property in the event of im-
proper use or use for which it is not intended.
2.3.2 Risk of death due to improper fastening
systems
The collectors may fall due to improper fastening systems.
Only the combination of Vailllant collectors and Vaillant
fastening systems has been tested. This combination can
withstand the forces caused by additional wind and snow
loads.
Only use the collector fastening systems that are ap-
proved by Vaillant.
2.3.3 Risk of death due to inadequate load-
bearing capacity of the roof
A roof with an insufficient load-bearing capacity may col-
lapse due to the additional load of the collectors.
Above all, additional wind and snow loads may result in
higher forces which could cause the roof to collapse.
Ensure that a structural engineer has confirmed the roof
as suitable for collector installation.
Only install the collectors on a roof that has adequate
load-bearing capacity.
2.3.4 Risk of death due to falling parts
Unsecured collectors can fall from the roof and present a
danger to persons.
Block off the areas in the fall area below the place of
work to a sufficient extent so that persons cannot be
injured by falling objects.
Indicate the working area, e.g. with information signs, in
accordance with the applicable regulations.
2.3.5 Risk of injury and material damage due to
incorrect maintenance and repairs
If maintenance or repair work is not carried out, or is car-
ried out incorrectly, this may result in injuries or in damage
to the solar plant.
Ensure that only an approved competent person carries
out maintenance and repair work.

Only fill and flush the collector with Vaillant ready-mixed
solar fluid.
Check the solar fluid regularly with an antifreeze tester.
2.3.12 Material damage due to an unsuitable tool
An unsuitable tool may damage the solar plant.
Only use a suitable tool.
In particular, only use the tool specified in the work steps
of this manual.
2.3.13 Risk of death from electric shock
Incorrect installation or a faulty power cable can result in a
supply voltage on the pipes, which can cause life-threaten-
ing injuries.
Secure earthing pipe clamps to the pipes.
Connect the earthing pipe clamps to a busbar using 16
mm² copper cable.
2.3.14 Material damage due to overvoltage
Overvoltage may damage the solar plant.
Earth the solar circuit to provide equipotential bonding
and overvoltage protection.
Secure earthing pipe clamps to the pipes.
Bond the earthing pipe clamps to a busbar using 16 mm²
copper cable.
2.3.15 Risk of death and material damage due to
contact corrosion
For roofs or façade sections made of metals more precious
than aluminium (e.g. copper roof), contact corrosion may
occur on the brackets. Collectors could fall and put persons
at risk.
Use suitable underlays to separate the metals.
2.3.16 Material damage due to snow falling from
roofs
If the collector field is installed below a sloping roof, then
snow falling from the roof may damage the collectors.
Install snow fences above the collectors as protection
against falling snow.

0020077994_02 auroTHERM exclusive Installation manual 15
Conditions: Parallel connection
To avoid pressure losses in the sub-collector fields, only
use parallel connection for collector rows with the same
number of collectors.
Ensure that each sub-collector field has the same total
tube length in the flow and return (Tichelmann system),
in order to avoid pressure losses in the connection tubes.
4.1.4 Preparing the roof duct
Caution.
Building damage due to penetrating wa-
ter.
If the roof duct is not prepared properly,
water may penetrate the building interior.
Ensure that the roof duct is prepared

4.1.6 Determining the number of required roof
brackets
1. Ask the local building authority for the regional max-
imum snow load s
k
.
Conditions: Maximum snow load: 3 kN/m²
Install 4 roof brackets per collector.
Conditions: Maximum snow load: 3 < × 4.5 kN/m²
Install 6 roof brackets per collector.
Conditions: Maximum snow load: > 4.5 kN/m²
Compile statistics for the individual case.
Ensure that the maximum permissible snow load per
collector is 5.4 kN/m².
Note
The maximum permissible load per roof
bracket type S/type P is: F
max
= 1.875 kN.
2. If you are using extension sets, ensure that the roof
bracket is positioned centrally with equal clearances.
4.1.7 Defining the edge clearances of the roof
brackets
Maximum lift points caused by wind loads can occur at
the cut-away edges of wall and roof areas (e.g. verge and
eaves). These maximum lift points result in high loads on
the collectors and installation systems.
Areas in which lift points occur are called edge areas.
Corner areas are zones in which edge areas overlap and
especially high pull forces occur.
Edge and corner areas must not be used as installation
areas.

5.1.1.3 Transporting collectors
1. To protect the collectors against damage, always trans-
port them when they are standing horizontally.
2. Transport the collectors to the roof using suitable aids.
5.1.2 Complying with clearances and installation
clearances
During storms, strong wind forces occur along the edges of
flat roofs.
When defining the installation position, maintain an edge
clearance of at least 1 m from the roof edge.
5.1.3 Selecting suitable connection
Select the appropriate connection for the collectors.
Ensure that the solar fluid flows through the collectors
either from left to right or from right to left.
Conditions: Number of VTK 1140/2 collectors: 1 7
max. 7 x VTK 1140/2
Switch up to 7 VTK 1140/2 units in series (according to
the 14 m² aperture surface area).
Conditions: Parallel connection, aperture surface area: 7 m²
Always connect as many collectors as possible in series,
even when several collector rows are arranged on top of
each other.
Note
Up to an aperture surface area of 7 m²
(accordingly for 3 pcs VTK 1140/2 + 1 pc
VTK 570/2), you must switch the collectors
in series.
Conditions: Parallel connection, aperture surface area: 14 m²
Set up several parallel collector rows and connect these
hydraulically in parallel.
Always connect as many collectors (at least 7 m²) as
possible in series.

36 Installation manual auroTHERM exclusive 0020077994_02
Conditions: Parallel connection
To avoid pressure losses in the sub-collector fields, only
use parallel connection for collector rows with the same
number of collectors.
Ensure that each sub-collector field has the same total
tube length in the flow and return (Tichelmann system),
in order to avoid pressure losses in the connection tubes.
5.1.4 Preparing the roof duct
Caution.
Lack of tightness due to destruction of
the roof skin.
In the event of destruction of the roof skin,
water may penetrate the building.
Ensure adequate protection of the roof
skin during installation on roof sealing

2. For detailed determination of the basic wind speed at the site and the required weights for the rack, use the Vaillant
tool for dimensioning the wind and snow loads.
3. For quick determination of the basic wind speed at the site, use the following map.
4. For quick dimensioning of the required weights, use the following tables.
Note
The map and tables are used for quick dimensioning of the ballast loads. Detailed dimensioning of the bal-
last loads is only possible using the Vaillant tool for dimensioning the wind and snow loads. If you have any
questions on this subject, please contact your responsible Vaillant sales partner.
