DO NOT DEFORM PIPE

 

 WHILE CUTTING

Be extra careful not to damage, dent, or 

deform the pipe while cutting. This will 

drastically reduce the heating efficiency 

 of the unit.

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

Proper flaring 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 flare 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. See 

Fig. 5.3

4. 

Remove PVC tape from ends of pipe when 

ready to perform flaring work.

5. 

Clamp flare form on the end of the pipe. 

The end of the pipe must extend beyond the 

edge of the flare form in accordance with the 

dimensions shown in the table below.
