Proper installation is crucial for the safe and efficient operation of your air conditioner. It is highly recommended that installation be performed by a qualified and authorized service technician.
3.1 Pre-Installation Checks
- Ensure the installation site meets the required clearances for both indoor and outdoor units.
- Verify that the electrical supply matches the unit's specifications (230 Volts).
- Confirm that the wall or mounting surface can support the weight of the indoor unit.
3.2 Indoor Unit Placement
The indoor unit should be mounted on a wall, ensuring sufficient space around it for proper airflow and maintenance. Avoid placing it above heat sources or in direct sunlight.

3.4 Electrical Connections
All electrical wiring must comply with local codes and regulations. Ensure a dedicated circuit breaker is used for the AC unit.
4. Operating Instructions
Your Hitachi AC offers various modes and features for optimal comfort and efficiency. Use the provided remote control for all operations.
4.1 Basic Operation Modes
- Auto Mode: The AC automatically selects the appropriate operating mode (Cool, Fan, Dry) based on the room temperature.
- Cool Mode: Provides cooling. Adjust the temperature using the remote control.
- Fan Mode: Circulates air without cooling.
- Dry Mode: Reduces humidity in the room.
4.2 Special Features
The Hitachi AC is equipped with advanced features to enhance your experience:
4.2.1 ice Clean (FrostWash) Technology
The ice Clean feature, powered by FrostWash Technology, helps maintain the cleanliness of the indoor unit's coil, ensuring consistent airflow and improved air quality. This feature operates in three steps:
- Freeze: The AC collects moisture from the room onto the indoor unit coil and freezes it to -15°C. Dust, bacteria, and other impurities adhere to this ice.
- Melt: The accumulated ice melts, washing away the trapped dust, bacteria, and mold with the water.
- Dry: Blowers dry the coil, removing any remaining moisture and impurities, leaving the coil clean.
To activate the ice Clean feature, press the 'FrostWash' button on your remote control. The AC will automatically initiate and complete the cleaning cycle based on room temperature and humidity.

4.2.2 Xpandable+ Technology (Auto Convertible AC)
The Xpandable+ technology allows your AC to intelligently detect changes in ambient temperature and room load requirements. It automatically adjusts the compressor's rotation per minute (RPM) to increase or decrease cooling capacity as needed. This means the AC can operate beyond its rated capacity, providing up to 110% cooling capacity when required, while also offering faster cool-down times and higher humidity removal.

4.2.3 Long Air Throw
The AC features a long air throw capability, distributing cool air up to 24 meters across the room. This creates an effective air circulation pattern, ensuring uniform cooling in every corner and eliminating hot air pockets. This results in faster cooling and reduced power consumption.

4.2.4 4 Way Swing
The 4 Way Swing feature allows for horizontal and vertical movement of the air flaps, ensuring multi-directional airflow and even distribution of cool air throughout the room.
4.2.5 Wi-Fi Enabled (airCloud Go)
With airCloud Go, your AC can be controlled remotely via Wi-Fi using a smartphone app. This allows you to manage settings, monitor energy consumption, and schedule operations from anywhere.

5. Maintenance
Regular maintenance ensures the longevity and efficient operation of your Hitachi AC.
5.1 Air Filter Cleaning
The pre-filter should be cleaned regularly (every two weeks or more often depending on usage) to prevent dust accumulation and maintain airflow.
- Turn off the AC and disconnect power.
- Open the front panel of the indoor unit.
- Remove the air filters.
- Clean the filters with a vacuum cleaner or wash them with lukewarm water and mild detergent.
- Allow filters to dry completely before reinserting them.

6. Troubleshooting
Before contacting customer support, please refer to the following common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| AC not turning on | No power supply, remote control battery low, circuit breaker tripped. | Check power connection, replace remote batteries, reset circuit breaker. |
| Insufficient cooling | Dirty air filters, blocked outdoor unit, low refrigerant, wrong mode selected. | Clean air filters, clear obstructions from outdoor unit, check mode, contact service for refrigerant. |
| Unusual noise | Loose parts, fan obstruction, compressor issue. | Check for loose parts, clear obstructions, contact service if noise persists. |
| Water leakage | Blocked drain pipe, improper installation. | Clear drain pipe, contact service for installation check. |
If the issue persists after attempting these solutions, please contact Hitachi customer support.
