Trench convector with energy-efficient EC tangential fan

Ready-to-install convector-based trench convectors
Assembly and installation instructions
Cleaning the tangential fan
A dirty tangential fan impairs the airflow and thus also the output of the
unit.
• If dirty, carefully clean the surfaces of the tangential fan with a cloth.
Clean the floor trench
A dirt floor trench, possibly caused by coarse dirt, impairs the airflow.
• If dirty, carefully vacuum the floor trench or use a cloth to clean if after
removing all components (grille, lid, bracing, tangential fans).
Clean the convector
A dirt convector, e.g. dusty deposits between the fins, impairs the airflow,
heat transfer and thus also the output of the unit.
• Carefully vacuum the heat exchanger if dirty. Do not use water to clean
the heat exchanger!
Caution:
Fins bend easily!
