5. Connecting the cold carrier
system (brine system)
The brine system, i.e. the ground collector loop, must be assembled and
connected by a qualified tradesman in accordance with current regulations
and design guidelines.
Care must be taken to ensure that no dirt gets on the collector hoses, which
must be washed clean before being connected. The protective caps must
remain in place at all times while work is in progress.
The temperature of the coolant system can fall below 0°C. It is therefore
important that water-based lubricants, etc. are not used during installation. It
is also important that all the components are insulated against condensation
to prevent the build-up of ice.
5.1 Connections
The brine system may be connected to the right, left or top of the heat
pump, as well as to its rear. Cut away the cover plate on the side where the
brine system is to be connected. When the opening has been made through
the cover plate, carry out the installation as follows:
1. In order to protect the brine hoses, fasten the protective edging provided
around the edge of the opening in the insulation plate. Adjust the length
of the protective edging to suit the opening as required.
2. Pass the brine hoses through the opening in the side cover plates and
connect them. Ensure that the insulation covers all parts of the brine
connection to prevent ice and condensation forming.
3. Then install the collector system according to the section Principal sketch
brine system.
It is also possible to connect the primary flow on one side of the heat
pump and the return on the other. Refer to section Dimensions sketch for
measurements and dimensions. The pipe dimension between the heat pump
and brine loop should be not less than Ø28 mm.

that you follow
