This document is an operation manual for Fujitsu General Limited's duct-type air conditioners, covering models ARTH18KMTAP, ARTH24KMTAP, ARTH30KMTAP, ARTH36KMTAP, ARTH45KMTAP, and ARTH54KMTAP. It provides essential information for safe and effective use, installation, and maintenance of the product.

Function Description

The Fujitsu duct-type air conditioner is designed to provide climate control for indoor spaces, offering multiple operation modes to suit various environmental needs. It functions as an air conditioner, capable of cooling, heating, dehumidifying (dry mode), and circulating air (fan mode). The unit utilizes R32 refrigerant, a low burning velocity material, which requires installation and servicing by qualified personnel to prevent fire and explosion risks in case of leakage. The product is designed for residential and commercial applications, aiming to improve indoor air quality and comfort.

Important Technical Specifications

Refrigerant: R32. This is a key specification, highlighting the need for specialized handling due to its low burning velocity and potential fire risk if leaked in an unventilated area and exposed to an ignition source.
Temperature Setting Range:
- Auto/Cooling/Dry: 18.0–30.0 °C
- Fan: Temperature cannot be set.
- Heating: 16.0–30.0 °C
Refrigerant Quantity: For products containing more than 1.842 kg of refrigerant, specific precautions regarding ventilation during installation are emphasized.
Electrical Safety: The unit requires a stable power supply and should be disconnected during extended periods of non-use or in case of malfunction. Power supply cables must not be damaged and should only be replaced by authorized service personnel.
Airflow: The unit features adjustable fan speeds (Auto, High, Med, Low, Quiet) to optimize comfort and energy efficiency.
Filter System: The unit includes air filters that need regular cleaning to maintain performance and air quality.

Usage Features

The air conditioner offers a range of features designed for user convenience and energy efficiency:

Operation Modes:
- Auto Mode: The unit automatically selects Cooling or Heating based on the room's current temperature relative to the set temperature. It monitors room conditions and adjusts operation accordingly.
- Cooling Mode: Used to cool the room. Users should set the temperature lower than the current room temperature for the fan to operate.
- Dry Mode: Gently cools while dehumidifying. The fan speed is automatically controlled and cannot be manually changed.
- Fan Mode: Circulates air without temperature adjustment.
- Heating Mode: Used to warm the room.
Timer Operations:
- On Timer/Off Timer: Allows users to set specific times for the unit to turn on or off.
- Weekly Timer: Enables scheduling of operation for up to 8 settings per day, across all 7 days of the week, for more advanced control and energy saving.
Energy Saving Operations:
- Economy Operation: Adjusts the set temperature by a few degrees to reduce energy consumption, particularly in Cooling/Dry and Heating modes.
- Fan Control for Energy Saving: The indoor unit fan may stop periodically during cooling or heating to save energy.
- Demand Response (DR) Mode: This feature allows the air conditioner to respond to signals from an electricity supplier to reduce power consumption during peak demand periods. It offers three DR modes (DR mode 1, 2, and 3) with varying levels of compressor operation and energy consumption reduction.
Quiet Operation: The "Quiet" fan speed setting is available for reduced noise levels, particularly during heating or cooling operations.
Automatic Defrosting Operation: In heating mode, if the outdoor unit's heat exchanger temperature drops too low, the unit automatically initiates defrosting to maintain efficiency.
Auto-restart Function: In case of a temporary power failure, the unit will automatically restart with the previous settings once power is restored.
Multiple Unit Control: The manual mentions options for multiple remote controllers, group control, and multi-split type air conditioner configurations, allowing for integrated control of several units.

Maintenance Features

Regular maintenance is crucial for the longevity and efficient operation of the air conditioner:

Air Filter Cleaning: The manual provides detailed instructions on how to remove and clean the air filters. Filters should be cleaned regularly (e.g., every 3 months or as indicated by the filter indicator) using a vacuum cleaner or by washing with mild detergent and water, then drying in the shade.
Filter Indicator Reset: After cleaning the filters, the filter indicator light on the remote controller needs to be reset.
Professional Servicing: The document strongly emphasizes that installation, repair, and relocation of the product must only be performed by qualified service personnel. Users are advised not to attempt to service the internal parts.
Periodic Checks: After long periods of use, it is recommended to have the indoor unit's mounting checked to prevent it from falling.
General Cleaning: The exterior of the unit should be cleaned with a soft, dry cloth. Harsh chemicals, solvents, or hot water should not be used.
Extended Non-use: When the product is not used for an extended period (e.g., one month or more), it is recommended to operate the unit in Fan mode for half a day to dry the internal parts thoroughly before storage. The power supply should be disconnected.

The manual also includes important safety precautions, such as avoiding direct exposure to airflow for extended periods, not inserting objects into the unit, keeping flammable gases away, and ensuring proper ventilation during use. It highlights symbols indicating warnings, cautions, prohibitions, and compulsory actions, ensuring users are aware of potential risks and proper handling procedures.
