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 wrench, a
spanner applying the following 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
and the efficiency of the unit will be better.
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/ ")
to prevent condensation even on the insulator when if the installed area is
warm and humid.
6 Shape an oil trap as shown in figure. The oil trap must be formed every
level difference of 10m/33ft.
A smaller one for the liquid refrigerant
A larger one for the gas refrigerant
The inside of copper pipe must be clean & has no dust.
