There are two refrigerant pipes of different diameters :

X
The inside of copper pipe must be clean & has no dust
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 wrench, a spanner applying the following torque.
2. Must use insulator which is thick enough to cover the refrigerant tube to protect the condensate water on the outside
of pipe falling onto the floor and the efficiency of the unit will be better.
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.
6. Do not use joints or extensions for the pipes that connect the indoor and outdoor unit. The only permitted connections
are those for which the units are designed.

Unscrew the pinch pipe at the end of each refrigerant pipe.
