The heat exchanger is best fitted vertically, this helps reduce air and dirt being trapped. Further information can be found in the relevant manual.
This depends on the medium and temperatures in the heat exchanger. For advice please contact UNEX technical support.

Welding and other similar processes create very high temperatures, which can damage gaskets and structure within the heat exchanger. Any work undertaken would invalidate the guarantee.
It is recommended to use mounting brackets. Additional load on the connections can lead to premature wear and will invalidate the guarantee.
Depending on the operating temperature, insulation prevents heat loss from the heat exchanger and prevents the risk of injury through burns.
