Duct installation
There are two installation methods of duct, as follows:
Drainage pipe installation
1. A shown in the picture, the indoor unit should be leaning to the drain hole to be
convenient for drainage.
2. The drain pipe must have downward gradient (1/50-1/100). If the drain pipe is
installed ups and downs or upward, it will lead to water backflow or leakage.
3. During the pipe connection, do not use too much force to the drain joint of indoor
unit.
4. There is a drain hole on each side of the indoor unit; unused drain pipe must be
closed.
5. The unit has drain pump which will lift up to 1200 mm.
 N.B
- The drain pipe must be wrapped heat insulation material (rubber insulation with
thickness more than 8mm), otherwise it will cause condensation or water drops.
