Frequently Asked Questions - EHF121S Mirage
How often should I clean the air filter?
Clean the washable antibacterial filter every two weeks to maintain optimal airflow and efficiency. A dirty filter can reduce cooling performance and increase energy consumption.
Can I install the air conditioner myself?
No, installation must be performed by qualified technicians. Improper installation can cause refrigerant leaks, electrical hazards, and void the warranty. Professional installation ensures safe electrical connections and proper vacuuming of the lines.
What is the recommended room size for this air conditioner?
With a 12000 BTU/h cooling capacity, the EHF121S is suitable for rooms up to 25 m² (about 270 sq ft). Factors such as ceiling height, insulation, and sunlight exposure can affect the effective area.
How do I set the timer on the remote control?
Press the TIMER button on the remote to cycle through modes. The ON timer lets you schedule the unit to start, while the OFF timer schedules the unit to stop. Use +/− buttons to adjust the time and confirm with the OK button.
What does error code E1 indicate?
E1 typically indicates a problem with the indoor temperature sensor. Check if the sensor is disconnected or damaged. Turn off the unit and restart after 10 minutes. If the code persists, contact customer service.
How can I switch between cooling and heating mode?
Use the MODE button on the remote to cycle through Auto, Cool, Dry, Fan, and Heat modes. Select the snowflake icon for cooling and the sun icon for heating. Wait a few minutes for the compressor to change over.
What type of refrigerant does the EHF121S use?
This model uses R410A refrigerant, which is chlorine-free and ozone-friendly. Always have a licensed technician handle refrigerant operations.
How do I use the sleep mode?
Press the SLEEP button on the remote. The unit will automatically adjust the temperature by +1°C per hour (for cooling) or -1°C (for heating) during sleep, and the fan runs at low speed to create a comfortable sleeping environment.
Why is water leaking from the indoor unit?
Water leakage is usually caused by a blocked condensate drain or dirty air filter. Clean the filter and check the drain hose for kinks or blockages. If the problem continues, the unit might need professional service to clear the pan or tubing.
How do I reset the remote control settings?
Press the RESET button on the remote with a pin or paperclip. This restores the remote to factory defaults. Also remove and reinsert the batteries for a full reset.
