5.2 Ciri Istimewa
5.2.1 ice Clean (FrostWash Technology)
The ice Clean feature, powered by FrostWash Technology, automatically cleans the indoor unit's coil to maintain optimal airflow and hygiene. This process involves three steps:
- bekukan: The AC condenses moisture from the room onto the IDU coil, forming ice at -15°C, trapping dust, viruses, bacteria, and mold.
- cair: The accumulated ice melts, washing away the trapped impurities with the water.
- kering: The blower dries the coil, removing any remaining moisture and preventing odor.
To activate, press the 'FrostWash' button on your remote control. The AC will automatically initiate and complete the cleaning cycle based on room temperature and humidity.

5.2.2 Teknologi Xpandable+
Hitachi's Xpandable+ technology allows the AC to intelligently sense the ambient temperature and room load. It automatically adjusts the compressor's rotation per minute (RPM) to increase or decrease the cooling capacity as needed. This ensures faster cooling, up to 110% of its rated capacity when required, and also helps in reducing humidity by 35% and achieving 30% faster cool-down times, leading to energy savings.

5.2.3 24m Long Air Throw
The 24-meter long air throw feature ensures that cool air reaches every corner of your room, creating a uniform air circulation pattern. This eliminates hot air pockets and provides consistent cooling throughout the space, enhancing comfort and reducing power consumption.

5.2.4 airCloud Go (Wi-Fi Enabled)
Control your Hitachi AC from anywhere using the airCloud Go mobile app. This Wi-Fi enabled feature allows you to adjust temperature, change modes, set timers, and monitor your AC's status remotely, providing convenience and smart home integration.
