The heat pump and collector hose in general

Install the collector as follows:

1. The compact collectors are installed horizontally. The collector should

lean with the connection side at least 30 cm above the bottom to aid the

venting process. Trench measurements: depth: 1 - 1.3 m, width: 2.5 m.

Minimum distance between two rows of compact collectors is 1 m.

Minimum distance between collectors and the house is 3 m. Trench

digging must adhere to applicable regulations.

2. Installation of the collectors can be simpliﬁ ed by joining up to ﬁ ve

collectors on the ground before they are positioned in the trench.

3. Place the collector modules in the trench, joined together using fusion

welded or compression ﬁ ttings.

4. Pressure test the system with air for 3-4 hours up to 4 bar prior to

ﬁ lling with heat transfer ﬂ uid. Reduce to 2 bar when backﬁ lling.

5. Reﬁ ll using sand or soil without stones.

6. Route the return line, 40 mm PEM, at a depth of 1 m.

7. Route the collector hoses up to the house wall. Hoses must be

insulated over the ﬁ nal 2 metres towards the house. Non-combustable

pipe material must be used when routing the pipes indoors.

property. Pipework should also be insulated where the ﬂ ow and return are

closer than 800 mm to each other.

Note
