Lift-up drain piping
If it is necessary to increase the height of the drain hose somewhat, install a lift-up drain piping.
1. Connect a lift-up drain pipe top to the drain hose with an adhesive for PVC.
2. Wrap the insulation drain with a vinyl tape.
3. Connect the lift-up drain pipe to the indoor unit drain hose with an adhesive for PVC.
4. Turn the lift-up drain piping, then adjust the height.
If it is raised higher than 550mm(21.65"), there can be water leaks.
If a concentrated drain hose is installed, refer to the figure below.
