There are two refrigerant pipes of differing diameters:
1 Remove the pinch pipe on the pipes and connect the assembly pipes to
each pipe, tightening the nuts, first manually and then with a torque

2 Must use insulator which is thick enough to cover the refrigerant pipe to
protect the condensate water on the outside of pipe falling onto the floor

3 Cut off any excess foam insulation.
4 Be sure that there must be no crack or wave on the bended area.
5 It would be necessary to double the insulation thickness(10mm or more)
to prevent condensation even on the insulator when if the installed area is
warm and humid.
