Inclined

Damaged surface

Cracked

Uneven thickness

CAUTION

If foreign matters or burrs are not removed after cutting the pipe, refrigerant gas may leak.

If foreign matters enter inside of the pipe, the important interior parts of the unit may get damaged or product efficiency will be reduced. Therefore, direction of the pipe should be downward during cutting or flaring the pipe.
