Shut-off valves installation
1)
Uncouple the return manifold (the one with medium flowing from
the heat pump to the geothermal probes) and connect the
shut-off valve. Position the seal and thread the nut fully onto the
manifold outlet.
5)
After having attached the manifold to the brackets, fully tighten
the nuts on the end cap and closure plate. If necessary this
operation can be carried out without the insulation inserted on
the end fitting.
4)
Position the manifold and mark the wall anchor holes on the wall.
Install the wall anchors and attach the brackets to the wall using
the mounting slots. If more convenient, the brackets can be
installed on the wall first, then connect the manifold to the
brackets.
2)
Uncouple the flow manifold (the one with medium flowing from
the geothermal probes to the heat pump) and connect the
regulating valves. The manifold is fitted for use with three
different circuit balancing systems.
6)
Determine the manifolds flow direction and attach the labels
supplied with the manifold. This will help with the installation of
the
circuits
and
the
respective
regulating
valves.
The
recommended flow direction is shown in the following figure:
