and
Flaring the Piping

12.2.7 Disposal of Outdoor Unit Drain Water
If a drain elbow is used, the unit should be placed on a stand which is taller than 3 cm.
If the unit is used in an area where temperature falls below 0°C for 2 or 3 days in succession, it is recommended
not to use a drain elbow, for the drain water freezes and the fan will not rotate.
1. To cut
When properly flared, the internal surface of the flare will evenly shine
and be of even thickness. Since the flare part comes into contact with
the connections, carefully check the flare finish.
