7 Refrigerant piping connection
C 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.
