12.3.8 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.
12.3.9 How to Replace Network Adapter
Remove the front grille (refer how to take out front grille) from the unit.
Remove the indicator piece by releasing the hook.
Remove 1 mounting screw, then remove the network adaptor holder.

(Drainage checking can be carried out without
removing the front grille.)
