Fig. 4.3 Preparatory work in the installation area
• Make sure that the substrate is sufficiently stable (see
Chap. 4.2 "Requirements for the installation site").
• Drill at least two core holes, taking the dimensions of
the unit and connections into account (see Fig. 4.3,
Pos.
1
).
• Each pipe from the heat source requires its own bore
hole.
• Special pipe feedthroughs must be used if there is a
risk of ground water penetration (follow the manufac-
turer's instructions).
• Take account of the distances to the core barrels for
the rest of the installation.
• Pass the heat source pipes (
2
) from the outside into
the installation area.
A connection for the condensate drain must be provid-
ed.
• Lay the heat source pipes (
2
) centrally in the bore
holes (
1
) to facilitate all-round thermal insulation.
• Seal the annular gap (
1
) as shown with foam insulation
(e.g. PE foam) (
3
).
• Insulate the heat source pipes in cellar areas against
vapour diffusion, as condensation will otherwise accu-
mulate (pipe temperature can be as low as -15 °C).
