Remote Control
Water Full Alarm
The water tray inside the air conditioner has a water level safety switch that controls the water level. When the water level reaches a specified height, the associated indicator light will illuminate. (If water pump is damaged, when the water tray is full, please remove the rubber plug at the bottom of the unit to drain water.)
- If you plan to leave this unit unused for an extended time, please remove the rubber plug from the drainage hole at the bottom of the unit and connect a drain hose to the lower fixing clip.
- You can also drain the water this way when the unit is operating in HEAT mode.
- If water pump is damaged, continuous drainage can be used by attaching adrain hose to the unit and placing it in a drain or sufficient receptacle. The unit can function properly this way as well.
- If water pump is damaged, intermittent drainage can also be used. Under this condition, pay attention to when the water full indicator light comes on.Then, connect a drain hose to the lower fixing clip to allow all water in the water tray to drain out. The unit can function properly this way.
Troubleshooting
Problem: Unit does not start when pressing on/off button.
- Water tank is full (check for blinking water full indicator light). Empty the water tank.
- Room temperature is higher than set temperature (while in heating mode). Reset the temperature.
- Room temperature is lower than set temperature (while in cooling mode). Reset the temperature.
Problem: The unit is noisy.
