Ground coil

Ground coil
The collector hose is a thin-walled hose PEM 40 x 2.4 PN 6.3 or PEM 40 PN 10. It is important that the
filling around the ground coil does not contain stones or other objects that could damage the hose. The
final filling is best carried out after the ground collector has been tested. Avoid fillings or dirt getting into
the coil when cutting.
Installation and filling around the collector hose must comply with local regulations.
Bending diameter
Minimum permitted bending diameter is 1 metre. Always use an elbow coupling for sharper bends. If you
damage the hose by bending it too much you can repair it with a straight coupling.
