Can the multilayered tube between the panel and the tank be buried as it is provided or does it need additional protection?

It is necessary to protect the tube when it is buried underground with a sleeve or sheath of the type “TPC” (Cable Protection Tube). This sheath must withstand crushing and be waterproof over its entire length.

The insulation of the pre-insulated tube is not designed to withstand moisture, so if there is a risk of contact with water, it is preferable to use insulators specifically built for this purpose.
