Frequently Asked Questions - RAS-E10HB HITACHI

How to clean the filter of the Hitachi RAS-E10HB air conditioner?

Turn off the appliance and unplug it. Remove the filter by pulling it downwards. Wash it with lukewarm soapy water, rinse and let it dry completely before reinstalling. Clean it every two weeks during intensive use.

What is the ideal temperature to avoid excessive power consumption?

In cooling mode, set the temperature between 24 and 26 °C. In heating mode, between 20 and 22 °C. Each additional degree can increase consumption by 7 to 10%.

The error codes on the indoor unit are flashing, what should I do?

Consult the manual to identify the code (e.g., LED indicator flashing). Common codes are: 2 flashes = sensor problem, 4 flashes = overload protection. If the problem persists, contact technical support.

Can I use the air conditioner without the remote control?

Yes, the on/off and function button are usually located on the indoor unit (under the front cover). It allows basic operation in automatic mode.

What type of refrigerant is used and is it eco-friendly?

The Hitachi RAS-E10HB uses refrigerant R32, which has a global warming potential (GWP) of 675, much lower than R410A. It is more efficient and environmentally friendly.

How to properly install the outdoor unit?

Place it on a flat, stable surface outdoors or in a well-ventilated area. Follow minimum clearances from walls (usually 10 cm at the rear, 30 cm on the sides). Avoid direct exposure to sunlight and rain. Professional installation is recommended.

What to do if the appliance does not cool enough?

First check the air filter: a clogged filter reduces airflow. Make sure doors and windows are closed. Check that the outdoor unit is not obstructed (leaves, etc.). If the problem persists, the refrigerant charge may be insufficient.

What is the power consumption in standby mode?

Standby consumption is very low, typically less than 1 W. To save energy, unplug the appliance during prolonged absence.

The air conditioner makes unusual noises, what should I do?

A gurgling noise is normal (refrigerant flow). A clicking sound at startup is also normal. If the noise is loud and continuous (vibration, whistling), check that the appliance is securely mounted and the filter is not blocked. Otherwise, call a technician.

Where can I find spare parts for this model?

Contact an authorized Hitachi dealer or customer service. Common parts (filters, remotes) are available online. Use the exact model number RAS-E10HB when ordering.

• Never use hot water (above 40°C), benzine, gasoline, acid, thinner or a brush, because they will damage the plastic surface and the coating.

3. MAINTENANCE BEFORE LONG OFF PERIOD

• Run the unit by setting the operation mode to ⚙ (COOL), the temperature to 32°C and the fan speed to HI for about half a day on a fine day, and dry the whole of the unit.
• Switch off the power plug or turn off the circuit breaker.

CAPABILITIES

Heating Capability

• This room air conditioner utilizes a heat pump system that absorbs exterior heat and brings it into a room to be heated. As the ambient temperature gets lower, heating capability will also lower. In such a situation, the inverter work to increase compressor rpm to keep the unit's heating capability from decreasing. If the unit's heating performance is still unsatisfactory, other heating appliances should be used to augment this unit's performance.
• The air conditioner is designed to heat an entire room so that it may take some time before you feel warm. Timer operation is recommended for effective preheating ahead of the desired time.
  Do not use a stove or any other hightemperature devices in proximity to the indoor unit.

Cooling and Dehumidifying Capabilities

- If the heat present in a room exceeds the unit's cooling capacity (for example, if there are many people in the room or other heating appliances are used), the preset room temperature may not be reached.
