Combination With Other Components; Operational Conditions; Maximum Wind Load; Maximum Standard Snow Load - Vaillant auroTHERM VFK 145/2 H Installation Manual

Avoid damage caused by incorrect assembly
In order to install flat collectors according to the installa-
tion manual, a qualified engineer is required.
> The installation should thus be performed only if a
qualified engineer is available.
> Use the fastening systems provided by Vaillant for the
flat collectors.
> Assemble the flat collectors as described in this man-
ual.
Avoid malfunctioning of the system caused by air
bubbles
> To fill the system, use the filling trolley to avoid air
bubbles.
> Use the manual air vent installed on the collector
field.
> Install the Vaillant solar automatic air vent in the
highest point of the system or insert the automatic
de-aerator in the solar circuit.
> Observe the relevant installation and operating man-
ual.
2.4

Combination with other components

Vaillant flat collectors should be combined only with
Vaillant components (fixing, connections) and system
components.
The use of other components or system components
shall be considered as improper use. We accept no liabil-
ity.
2.5

Operational conditions

a
Danger!
Danger of personal injury and material
damage caused by a collapsing roof!
A roof with insufficient load-bearing capacity
can collapse as a result of the additional load-
ing caused by the flat collectors.
> Before installation, check the maximum
roof load!
> Mount the flat collectors only on roofs with
a sufficient load-carrying capacity.
> If necessary, call a technician.
b
Caution!
Leaks!
With roof pitches 22° rainwater can collect
on the cover plates and leaks can occur.
> Only install multi-row flat collectors in-roof
if the roof pitch is between 22° and 75°.

2.5.1

Maximum wind load

The flat collectors are suitable for a maximum wind load
2
of 1.6 kN/m .

2.5.2 Maximum standard snow load

The flat collectors are suitable for a maximum standard
snow load of 5.0 kN/m 2 .

2.5.3 Roof pitches

> Only install multi-row flat collectors in-roof if the roof
pitch is between 22° and 75°.

2.5.4 Edge distances

> Maintain a distance of at least 1 metre from the edges
of the roof and the ridge.
> Do not fit the collectors on a roof overhang.

CE label

The CE label states that the units as described in the
type overview satisfy the basic requirements of the fol-
lowing directives:
– Directive 97/23/EWG of the European Parliament and
Council for harmonization of the laws of the member
states regarding pressure equipment.
auroTHERM flat collectors are built accord-
ing to the state of the art and recognised
safety rules and regulations.
Conformity with the applicable standards
has been demonstrated.
auroTHERM flat collectors have been suc-
cessfully tested according to the rules and
requirements for the Solar Keymark.
