Connecting The Refrigerant Pipe - Samsung AVMKH020CA0 Installation Manual

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 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.
Outer Diameter
6.35 mm (1/4")
9.52 mm (3/8")
12.70 mm (1/2")
15.88 mm (5/8")
19.05 mm (3/4")
22.23 mm (7/8")

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.
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.
