Contact authorized service provider for any unit repairs or maintenance.
This manual provides instructions for operating and maintaining your split-type room air conditioner.
Key operations include:
Regular maintenance, such as cleaning filters, is recommended for efficient cooling and heating.
| Problem | Possible causes | Solution |
|---|---|---|
| Unit does not turn on when pressing ON/OFF button | The Unit has a 3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off. | |
| The unit changes from COOL/HEAT mode to FAN mode | The unit may change its setting to prevent frost from forming on the unit. Once the temperature increases, the unit will start operating in the previously selected mode again. | |
| The set temperature has been reached, at which point the unit turns off the compressor. The unit will continue operating when the temperature fluctuates again. | ||
| The indoor unit emits white mist | In humid regions, a large temperature difference between the room's air and the conditioned air can cause white mist. | |
| Both the indoor and outdoor units emit white mist | When the unit restarts in HEAT mode after defrosting, white mist may be emitted due to moisture generated from the defrosting process. | |
| The indoor unit makes noises | A rushing air sound may occur when the louver resets its position. | |
| A squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit's plastic parts. | ||
| Both the indoor unit and outdoor unit make noises | Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units. | |
| Low hissing sound when the system starts, has just stopped running, or is defrosting: This noise is normal and is caused by the refrigerant gas stopping or changing direction. | ||
| Squeaking sound: Normal expansion and contraction of plastic and metal parts caused by temperature changes during operation can cause squeaking noises. | ||
| The outdoor unit makes noises | The unit will make different sounds based on its current operating mode. | |
| Dust is emitted from either the indoor or outdoor unit | The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity. | |
| The unit emits a bad odor | The unit may absorb odors from the environment (such as furniture, cooking, cigarettes, etc.) which will be emitted during operations. The unit's filters have become moldy and should be cleaned. | |
| The fan of the outdoor unit does not operate | During operation, the fan speed is controlled to optimize product operation. | |
| Operation is erratic, unpredictable, or unit is unresponsive | Interference from cell phone towers and remote boosters may cause the unit to malfunction. In this case, try the following: • Disconnect the power, then reconnect. • Press ON/OFF button on remote control to restart operation. | |
| Poor cooling performance | Temperature setting may be higher than ambient room temperature | Lower the temperature setting |
| The heat exchanger on the indoor or outdoor unit is dirty | Clean the affected heat exchanger | |
| The air filter is dirty | Remove the filter and clean it according to instructions | |
| The air inlet or outlet of either unit is blocked | Turn the unit off, remove the obstruction and turn it back on | |
| Doors and windows are open | Make sure that all doors and windows are closed while operating the unit | |
| Excessive heat is generated by sunlight | Close windows and curtains during periods of high heat or bright sunshine | |
| Too many sources of heat in the room (people, computers, electronics, etc.) | Reduce amount of heat sources | |
| Low refrigerant due to leak or long-term use | Check for leaks, re-seal if necessary and top off refrigerant | |
| SILENCE function is activated(optional function) | SILENCE function can lower product performance by reducing operating frequency. Turn off SILENCE function. | |
| The unit is not working | Power failure | Wait for the power to be restored |
| The power is turned off | Turn on the power | |
| The fuse is burned out | Replace the fuse | |
| Remote control batteries are dead | Replace batteries | |
| The Unit's 3-minute protection has been activated | Wait three minutes after restarting the unit | |
| Timer is activated | Turn timer off |
