6. Place fl aring tool onto the fl aring block.
7. Turn the handle of the fl aring tool clockwise until the pipe is fully fl ared.
8. Remove the fl aring tool and fl aring block, then inspect the end of the pipe
for cracks and even fl aring. Slide the nut up to see if the fl are is of proper
diameter and does not interfere with the threads in the fl are nut.

Step 4: Connect pipes
When connecting refrigerant pipes, be careful not to use excessive torque or to
deform the piping in any way. You should fi rst connect the low-pressure (suction)
pipe, then the high-pressure pipe (liquid line).
Minimum Bend Radius
When bending connective refrigerant piping, the minimum bending
radius is 10cm (4in). See Figure 52.
