Drain hose
CAUTION
Check that the indoor unit is level with the ceiling by
using the leveller.
• Install air ventilation to drain condensation smoothly.
• If it is necessary to increase the height of the drain pipe,
install the drain pipe straight within 300 mm from the
drain hose port. If it is raised higher than 550 mm, there
may be water leaks.

• Do not give the hose an upward gradient beyond the
connection port. This will cause water to flow backwards
when the unit is stopped, resulting in water leaks.
