1 Liquid line (refrigerant)
2 Suction gas line (refrigerant)
»
Ensure that the necessary preparatory work on refrig-
erant lines underground or in open air has been fully
completed.
»
Open up the connections for the liquid and suction
gas lines on the indoor and outdoor units using a suit-
able pipe cutter.
»
Connect the liquid and suction gas lines to the indoor
and outdoor units of the heat pump system.
»
When soldering, ensure that neither moisture nor dirt
can penetrate into the refrigerant lines. When solder-
ing, always use forming gas.
»
Ensure that soldered joints are properly sealed.
10.5.2 Checking for leak tightness
After the refrigerant lines have been installed, the leakage
test on the refrigerant circuit is carried out.
i
Information
Nitrogen can become trapped in magnetic valves
and expansion valves in the refrigerant circuit.
»
Before carrying out the leakage test, open all
magnetic valves and expansion valves in the
refrigerant circuit.
»
Evacuate the refrigerant lines.
»
Use a suitable medium to carry out the leakage test
according to standard regulations.
10.5.3 Filling the refrigerant circuit with refrigerant
»
Empty the refrigerant lines.
»
Allow the refrigerant to flow into the refrigerant circuit.
Material damage
Operating the heat pump with too little or no refrig-
erant will damage the appliance.
10.5.4 Insulating the refrigerant lines
»
Insulate refrigerant lines with suitable insulating mate-
rial wherever they are still exposed to the air between
the indoor and outdoor units, to prevent formation
of condensation. When passing through open air
outside, the insulating material must also have UV
protection.
i Information
Insulation used beneath the soil must be made of
a closed-cell material. Otherwise, the thermal in-
sulation of the material will be impaired.
