There are two refrigerant pipes of dierent diameters :

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, rst 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 oor
and the eciency of the unit will be better.
3. Cut o 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(0.39inch(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.
