There are 2 refrigerant pipes of diameters:

•The smaller one is for the liquid refrigerant

•The larger one is for the gas refrigerant

need to extend the pipe using the assembly pipe (optional).

	The connection procedure for the refrigerant pipe varies
	according to the exit position of the pipe when facing the wall:		A	B
