more precious than aluminium (e.g. copper
roofs), contact corrosion may occur on the
anchors. As a result, the anchors may buckle
and the products may fall.
▶Use suitable underlays to separate the
metals.
1.3.5 Risk of burns, scalds and frostbite
due to hot and cold components
There is a risk of burns and frostbite from
some components, particularly uninsulated
pipelines.
▶Only carry out work on the components
once they have reached environmental
temperature.
1.3.6 Risk of injury due to the heavy weight
of the product
▶Make sure that the product is transported
by at least two people.
1.3.7 Risk of burns caused by hot product
surfaces
The products become very hot when the sun
is shining. If you touch the products without
protection, you could burn yourself.
▶Ensure that the collectors are covered
before starting the installation.
▶Remove the sun protection film installed at
the factory only after the solar system has
been started up.
▶Avoid performing installation and mainten-
ance work under direct sunlight.
▶You should preferably perform the work in
the morning.
▶Wear suitable protective gloves.
1.3.8 Risk of injury due to breaking glass
The glass of the collectors may break due to
mechanical impact or torsion.
▶Wear suitable protective gloves.
▶Wear suitable protective goggles.
1.3.9 Material damage due to overvoltage
Overvoltage may damage the solar system.
▶Earth the solar circuit to provide equipoten-
tial bonding and overvoltage protection.
▶Secure the pipe clamps for earthing to the
pipelines.
▶Connect the pipe clamps for earthing to a
busbar using a 16 mm²copper cable.
1.3.10 Material damage due to lightning
Lightning may damage the solar system.
▶Connect the solar system to a lightning
protection device in accordance with the
applicable regulations.
1.3.11 Material damage due to snow falling
from roofs
If the solar system is installed below a slop-
ing roof, then snow falling from the roof may
damage the collectors.
▶Install snow guards above the solar sys-
tem as protection against falling snow.
1.3.12 Material damage caused by a high-
pressure cleaner
High-pressure cleaners may damage the
collectors due to the extremely high pressure.

clearances
Condition: On-roof installation
▶In order to install the collectors correctly, you must main-
tain (→Page 14)the clearances and installation clear-
ances that are necessary for pitched roofs.
Condition: Flat-roof installation
▶When installing the products on flat roofs, maintain a
clearance of at least 1 m from the edge of the roof in
order to avoid particularly strong wind forces along the
edge of the roof.
4.1.6 Selecting suitable connection
▶Observe the planning information when designing the
flow rate for the array (if available).
▶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.
Condition: 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 m²aperture surface area).
Condition: 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.
Condition: 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.

4 Set-up
10 Installation and maintenance instructions auroTHERM exclusive 0020077989_04
Condition: 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
pipe length in the flow and return (Tichelmann system), in
order to avoid pressure losses in the connection pipes.
4.1.7 Preparing the roof duct
Condition: On-roof installation
Caution.
Building damage due to penetrating wa-
ter.
If the roof duct is not prepared properly, wa-
ter may penetrate the building interior.
▶Ensure that the roof duct is prepared
properly.
▶Make a v-shaped cut in the roofing felt membrane.
▶Fold the upper, wider flap onto the roof batten above,
and fold the lower, narrower flap onto the roof batten
below.
▶Fix the roofing felt membrane tight to the roof batten, so
that any moisture runs off to the side.
Condition: Flat-roof installation
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
surfaces.
▶Place large-area building protection mats
underneath the installation system.
▶After installation, check the tightness of
the building shell where there are directly
connected racks.

4.2.2 Determining the number of required roof
anchors
1. Ask the local building authority for the regional max-
imum snow load sk.
Condition: Maximum snow load: ≤3 kN/m²
▶Install 4 roof anchors per collector.
Condition: Maximum snow load: 3 … 4.5 kN/m²
▶Install 6 roof anchors per collector.
Condition: 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 an-
chor type S/type P is: Fmax. = 1.875 kN.
2. If you are using extension sets, ensure that the roof
anchor is positioned centrally with equal clearances.
4.2.3 Defining the edge clearances of the roof
anchors
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.

The racks are designed for basic wind speeds of up to 108 km/h. If the basic wind speed at the site is
greater than 108 km/h, then there can be no guarantee claim for the system.
▶Only install the rack in locations where the basic wind speed is a maximum of 108 km/h.
1. Please note the following for floating installation:
Installation variants Please note
B
Weights that are firmly screwed onto the
rack must consist of material capable of
screw connections.
A and B All weights must be weatherproof.
2. For quick determination of the basic wind speed at the site, use the following map.
3. For quick dimensioning of the required weights, use the following tables.
Note
Detailed dimensioning of the ballast loads is only possible using the Vaillant tool for dimensioning the wind
and snow loads. If you have any questions on this subject, contact your responsible Vaillant sales partner.
