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 re­cognised 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 improper 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 load­bearing capacity of the roof
A roof with an insufficient load-bearing capacity may collapse 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 carried 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.
2.3.6 Risk of death due to inadequate fastening of the collectors
Collectors can fall from their anchors if they are not properly fastened on the roof. Collectors falling from the roof could cause life-threatening accidents.
Perform all work steps as described in this manual.Observe all safety precautions described in this manual.In addition, comply with all safety regulations that spe-
cifically apply in your region.

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.
2.4 Intended use
2.4.1 Intended use
Vaillant auroTHERM VTK tube collectors are used for solar heating support and for solar-supported hot water genera­tion.
2.4.2 Suitability of the equipment
The collectors must only be operated with Vaillant ready­mixed solar fluid. Passing heating water or hot water directly through the collectors constitutes improper use.
2.4.3 Improper use
Any use which is not explicitly mentioned in the chapter "In­tended use" (Page 6) is deemed improper.
Any other or additional use does not comply with the in­tended use. Any direct commercial or industrial use is also deemed to be improper. The manufacturer/supplier is not li­able for any damage resulting from such use. The user alone bears the risk.
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-threatening injuries.

4.1.6 Determining the number of required roof
brackets
1. Ask the local building authority for the regional max­imum snow load sk.
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
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.
