Installation Guide
The brine pipes must be insulated from the heat pump, through the walls and outside the house all the way to the collector so as to
avoid condensation and prevent heat loss.
If the brine pipes are to be routed above ground, drill holes in the walls for them.
If the brine pipes are to be routed below ground see the instructions below.

1. Drill holes in the wall for the insert pipes (1) for the brine pipes. Follow the dimension and connection diagrams. If there is any risk
of groundwater infiltration at brine pipe lead-ins, watertight grommets must be used.
2. Position the insert pipes (1) in the holes sloping downwards. The inclination must be at least 1cm every 30 cm. Cut them at an angle
(as illustrated) so that rain water cannot get into the pipes.
3. Insert the brine pipes (2) into the insert pipes in the installation room.
4. Fill in the holes around the lines with mortar (3).
5. Ensure that the brine pipes (2) are centred in the insert pipes (1) so that the insulation is distributed equally on all sides.
6. Seal the insert pipes (1) with a suitable sealant (foam) (4).
