Symbol Explanation - Danfoss DHP-A Installation Instructions Manual

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.

Figure 32. Making holes
1. Drill holes in the wall for the insert pipes (1) for the brine pipes. Follow the dimension and connection dia-
grams. 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
30cm. 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).
5.3.6 Installing brine pipes
1. Determine to which side the brine pipes are to be connected.
2. Route the out pipe for brine in through the corresponding hole (with rubber collar) in the heat pump side.
3. Install all necessary components on the pipe. Remember to install the filler cock with the filter cover
upwards.
4. Route the pipe for brine out through the corresponding hole (with rubber collar) in the heat pump side.
Caution! When the brine lines are connected to the right for DHP-A, the brine out line must be routed
over the brine pump, under the compressor's vacuum pipe and under the condenser's flexible hose, see
figure below.
