45MBCAQ: Installation Instructions
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 cannot put them on or change their direction
after flaring.
4. Remove PVC tape from ends of pipe when ready to perform flaring work.
5. Clamp flare from on the end of the pipe. The end of the pipe must extend beyond the flare form.
6. Place flaring tool onto the form.
7. Turn the handle of the flaring tool clockwise until the pipe is fully flared.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
