Notes:
l Protect the drain cover and water stopper properly.
l Move the unit carefully to avoid the leakage it is necessary.
l Tilt the unit slightly backwards when draining.
l Block the drain hole as soon as possible before the tray is full if it cannot hold all water
in the unit to prevent the water leakage and wet the floor or carpet.
l Water stopper and drain cover must be tightly installed, to avoid new condensate to
wet the floor or carpet when the unit re-starts working.
2. Continuous drainage
1) Screw off the drain-cover & unplug the water stopper.
2) Connect drain-hole with φ12mm drain hose, as deep as possible to avoid leakage.
3) Pull the drain hose to bathroom or outdoor.

l Drain hose must be installed when there’s no water in the tray.
l It is suggested that not to use continuous drainage when unit is in COOL mode, to
ensure enough water recycle in the unit to enhance the system cooling effects.
l It is suggested that to adopt continuous drainage when unit is in HEAT mode, to avoid
frequent drainage.
l Put the drain hose in an inaccessible place, not higher than drainage hole and keep
drain hose straight without any flexure.
l Keep the drain cover and its stopper properly when continuous drainage is adopted.
