Step 2: Remove burrs
Burrs can affect the air-tight seal of refrigerant piping
connection. They must be completely removed.
1. Hold the pipe at a downward angle to prevent
burrs from falling into the pipe.
2. Using a reamer or deburring tool, remove all
burrs from the cut section of the pipe.

Step 3: Flare pipe ends
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.

Step 4: Connect pipes
When connecting refrigerant pipes, be careful not
to use excessive torque or to deform the piping in
pipe, then the high-pressure pipe.
MINIMUM BEND RADIUS
When bending connective refrigerant piping, the
minimum bending radius is 4 inches.
