7. Connecting the 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.
7.1 Connections
The brine system may be connected to the right, left or back of the heat pump. Cut
away the cover plate on the side where the brine system is to be connected. The
insulation on the inside of the cover plate has been grooved to enable an opening to
be cut for the brine hoses provided. When the opening has been made through both
the insulation and 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. Attach the provided compression couplers to the cooling module connector pipes.
To facilitate attachment, the upper brine pump connection may be loosened and
rotated if necessary.
3. Pass the brine hoses through the opening in the side cover plates and connect
them to the compression couplers. Ensure that the connections are well insulated
to avoid the build-up of ice and condensation.
4. Install the collector system after this according to the schematic diagram.
You can also connect the primary flow on one side and the return on the other. See
the section entitled “Measurement details for measurements and dimensions”. The
pipe between the heat pump and collector loop should have an internal diameter of no
less than Ø28 mm.
