Common Issues and Troubleshooting
-
**Unit Does Not Start**
This problem can be due to a lack of electricity, needing to replace the remote control batteries, improper connection of the power cord, or a tripped safety LCDI plug for users in the USA, Canada, or Mexico -
**Runs but Does Not Cool**
This can occur if a door or window is open, the dust filter is dirty, the exhaust hose is detached, the temperature setting is too high, the air outlet or intake is blocked, the room exceeds the recommended size, or large numbers of windows are reducing cooling effectiveness -
**Runs a Short While Only**
This issue might be due to the thermostat temperature being set too close to the room's temperature, a blocked air outlet, or tight bends in the air exhaust hose -
**Power Button Blinking (Water Full Indicator)**
This indicates excess water condensation inside the unit, requiring the user to drain the water -
**Heater Not Switching On**
If the heating function has not been activated or the ambient temperature is too high, the heater might not switch on. This feature is for models with the heating function only

Energy Efficiency Tips
- Keep doors and windows closed when the air conditioner or dehumidifier is running to prevent warm air from entering and cool air from escaping.
- Clean the dust filter every two weeks to maintain air cooling efficiency, as a dirty filter can restrict airflow and reduce the unit's efficiency.
- Use the programmable timer to schedule the air conditioner to turn on or off, reducing unnecessary operation and conserving energy.
- Set the temperature setting to a comfortable but not excessively low temperature to avoid overworking the air conditioner.
- Ensure the exhaust hose is properly installed and not bent, as obstructions can hinder performance and lead to higher energy consumption.
- Do not use the appliance in a room with continuously operating sources of ignition such as open flames or in areas where flammable substances are stored.
- Ensure that the unit is connected to a properly grounded outlet and do not use an extension cord with this unit.
- Never touch the power plug or the air conditioner with wet hands to avoid electrical shock.
- Do not attempt to repair or modify the appliance yourself. For any service or repair needs, contact a registered professional to avoid danger.
- Keep the unit clear of obstructions at all times, and ensure good ventilation to prevent overheating.
