Danger!
Risk of burns from hot components!
The U tube, heat conducting plate and the
interior of the vacuum tubes become warm
as a result of solar radiation and may cause
scalding.
▶ Wear suitable safety gloves.
▶ Wear suitable protective goggles.
1. Only use genuine Vaillant replacement tubes (article
number 0020077347).
Note
If a tube has been damaged by a hailstorm,
for example, the individual tube can be re-
placed.
The solar plant can remain in operation
when replacing the tube.
2. Observe the relevant installation manual that is en-
closed with the replacement tube.
7.2.7 Disposing of defective tubes
The Vaillant tubes consist largely of recyclable materials.
The Vaillant tubes must not be disposed of with normal
household waste.
▶ Observe the applicable regulations.
▶ Dispose of defective Vaillant tubes properly.
