General information
Ensure that the appliance is accessible from all sides.
Ensure that the base is level, even, solid and permanent.
Ensure the entire appliance frame is in full contact with the
substrate. Uneven substrates can increase noise emissions.

Observe the following information:
- Use weather-resistant cables.
- Protect the heating circuit flow and return lines against frost
with sufficient thermal insulation. Provide thermal insulation
in accordance with applicable regulations.
- Also protect all supply lines/cables against humidity, damage
and UV radiation by means of a conduit.
