Step 3: Flare pipe ends
Proper aring is essential to achieve an airtight
seal.
1.
After removing burrs from cut pipe, seal
the ends with PVC tape to prevent foreign
materials from entering the pipe.
2.
Sheath the pipe with insulating material.
3.
Place are nuts on both ends of pipe.
Make sure they are facing in the right
direction, because you can’t put them on
or change their direction after flaring.

ready to perform aring work.
5.
Clamp are form on the end of the pipe.
The end of the pipe must extend beyond
the are form.

8. Remove the aring tool and are form,
then inspect the end of the pipe for cracks
and even aring.
Step 4: Connect pipes
Connect the copper pipes to the indoor unit rst,
then connect it to the outdoor unit. You should
rst connect the low-pressure pipe, then the high-
pressure pipe.
1.
When connecting the are nuts, apply a
thin coat of refrigeration oil to the ared
ends of the pipes.
2. Align the center of the two pipes that you
will connect.
