4. Remove tape from ends of pipe when ready to perform fl aring work.
5. Clamp fl are form on the end of the pipe. The end of the pipe must extend
beyond the edge of the fl are form in accordance with the dimensions shown
in the Table 6.

Step 4: Connect refrigerant line set
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 32.
