12.3.7 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.
Hose
Install the hose at an angle so that the
water smoothly fl ows out.
