Connecting the refrigerant pipe
There are two refrigerant pipes of differing diameters:
• 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.
1. Before connecting the refrigerant pipe, open the cover side.
2. 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.
