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.
Horizontal installation
The following equipment is used for the collector installation:
Hose welding
equipment
Hose pliers
Fusion weld sleeve
Ø40 mm
Pipe coupling
1 inch BSP
Compression connector
Compact collector
The heat pump and collector hose in general
Insulation of pipework
All collector pipework should be insulated a minimum of 2 metres from the
property. Pipework should also be insulated where the fl ow and return are
closer than 800 mm to each other.
Note
A maximum of 11 compact collectors
can be installed in each row.
Note
Health and safety requirements to
ensure that the sides of the trench
are not liable to collapse must be
observed.
