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.
