Smartformer and any obstacle in front of it. This makes it easier to open the door of the
Smartformer.
Destruction of the Smartformer due to insufficient heat dissipation
The Smartformer can overheat if there is insufficient heat dissipation. Frequent overheating can
destroy the Smartformer in the long term.
• Maintain the minimum clearance to walls and adjacent devices or objects. As a result,
sufficient heat dissipation is ensured.
• If the Smartformer is installed together with other electrical devices in areas with high ambient
temperatures, increase the distances between the Smartformer and the other electrical devices
and provide a sufficient fresh-air supply. This prevents the Smartformer
from drawing in the
exhaust air from adjacent devices.
