Outline drawings for the collector hose in the ground and through a wall
The drawings below show how to run the collector hose in the ground and
through a wall. The soil fi lling around the hose must not contain stones. If
the hose is ploughed down, you must use equipment that guarantees the
hose is laid at the right depth.

Connecting the collector hose to the heat pump
It is important that the collector hose has been pressure tested before it is
connected to the heat pump. Pressure testing is carried out by the boring
company or excavating company and determines whether the hose is in
one piece and works as it should. A ground collector is usually pressurised
during the laying process.
A further leakage test must be performed on the collector hose before
commissioning the heat pump.
