Es geht um ein Installationshandbuch für bodenstehende Inneneinheiten von Klimaanlagen. Hier handelt es sich um die Vorsichtsmaßnahmen bei der Installation der Rohrleitungen. Bei *flare nuts* bräuchte ich Hilfe. Danke im Voraus.

Cautions
• Daub the surfaces of the flare pipe and the joint nuts with frozen oil, and wrench it for 3~4 rounds with hands before fasten the *flare nuts*. (Refer to chart 12)
• Be sure to use two wrenches simultaneously when you connect or disconnect the pipes.
2) The stop valve of the outdoor unit should be closed absolutely (as original state). Every time you connect it, first loosen the nuts at the part of stop valve, then connect the flare pipe immediately (in 5 minutes). If the nuts have been loosened for a long time, dusts and other impurities may enter the pipe system and may cause malfunction later. So please expel the air out of the pipe with refrigerant before connection.
3) Expel the air (refer to the Expel The Air ) after connecting the refrigerant pipe with the indoor unit and the outdoor unit.
Then fasten the nuts at the repair-points.
