Samsung AR10NVFSCURNSV manual Shortening or extending the refrigerant pipes assembly pipe

Page 34

1Cut out the appropriate knock-out piece (A, B, C) on the rear of the indoor unit unless you connect the pipe directly from the rear.

2Smooth the cut edges.

3Remove the protection caps of the pipes and connect the assembly pipe to each pipe. Tighten the nuts first with your hands, and then with a torque wrench, applying the following torque:

Outer diameter (mm)	Torque (N•m)	Torque (kgf•cm)

ø 6.35	14 to 18	140 to 180

ø 9.52	34 to 42	350 to 430

ø 12.70	49 to 61	500 to 620

ø 15.88	68 to 82	690 to 830

NOTE

•If you want to shorten or extend the pipes, see Step 2.7 Shortening or extending the refrigerant pipes (assembly pipe) on page 34.

4Cut off the remaining foam insulation.

5If necessary, bend the pipe to fit along the bottom of the indoor unit. Then pull it out through the appropriate hole.

•The pipe should not project from the rear of the indoor unit.

•The bending radius should be 100 mm or more.

6Pass the pipe through the hole in the wall.

NOTE

•The pipe will be insulated and fixed permanently into position after finishing the installation and the gas leak test. For further details. see Step 4.1 Performing the gas leak tests on page 40.
