This document is an owner's manual for a Dawlance Inverter Split Type Room Air Conditioner, covering models such as Chrome, Chrome Plus, Chrome Pro, Avante, Avante Plus, and Inverter 30. It provides essential information for safe operation, maintenance, and installation of the air conditioner.

Function Description

The Dawlance Inverter Split Type Room Air Conditioner is designed to provide cooling, heating (model dependent), and drying functions for indoor spaces. It operates on the heat-pump principle, absorbing heat from the outdoors and transferring it indoors during heating mode. The inverter technology allows for efficient temperature control and energy saving.

The unit features an AUTO operation mode, where it automatically selects cooling, heating, or fan-only operation based on the set temperature and the room temperature, maintaining a constant room temperature of 25 degrees Celsius.

A SLEEP operation mode is available, which adjusts the set temperature by 1°C/2°F per hour for the first two hours (increasing during cooling, decreasing during heating) and then maintains this new temperature for five hours before switching off. This mode is designed to save energy and enhance night-time comfort by synchronizing with the body's metabolism.

For dehumidification, the DRYING operation mode regulates temperature by repeatedly cycling between cooling and fan-only operations, with the fan speed set to LOW.

The air conditioner includes a display window that shows temperature settings during operation, 'dF' during defrosting, and 'CL' when the anti-cold air feature is active in heating mode. Some models also feature an ECO display for energy-saving mode.

Usage Features

Before using the air conditioner, users are advised to read the manual carefully and keep it for future reference. Safety precautions are highlighted, including warnings against extending cables, using multiple plugs, exposing the body to cool air for prolonged periods, poking objects into vents, attempting self-repair, pulling the plug by the cable, or operating in wet rooms. Users are instructed to remove dirt from the power plug, switch off the device immediately if abnormalities occur, and always switch off and unplug before cleaning. Installation and repair should be performed by authorized personnel.

The manual specifies operating temperature ranges for optimal performance:

Cooling operation: Room temperature 16°C~32°C (60.8°F~90°F), Outdoor temperature -10°C~52°C (14°F~126°F).
Heating operation: Room temperature 14°C~30°C (57.2°F~86°F), Outdoor temperature -15°C~24°C (5°F~75°F).
Drying operation: Room temperature 16°C~32°C (60.8°F~90°F), Outdoor temperature -10°C~52°C (14°F~126°F).

Operating the air conditioner outside these conditions may trigger safety protection features, causing abnormal function. In high humidity (over 80%) during cooling, condensed water may drip; users are advised to set the vertical airflow louver to its maximum angle (vertically to the floor) and use HIGH fan mode.

A manual operation switch is available for emergency use if the remote controller fails or during maintenance. To access it, the front panel must be opened. Pressing this button acts as an ON/OFF switch, retaining previous settings. This switch is primarily for testing and should not be used unless necessary. To resume remote controller operation, the remote controller should be used directly.

Airflow directional control can be adjusted to prevent discomfort or uneven room temperatures. The horizontal louver is adjusted using the remote controller, while the vertical louver is adjusted manually. The horizontal louver can move incrementally or continuously swing up and down automatically. The manual advises against setting the airflow direction downward in cooling or dehumidifying mode for extended periods to avoid condensation dripping. After a quick restart, the horizontal louver may remain static for about 10 seconds. The open angle of the horizontal louver should not be too small, as this can reduce cooling or heating performance. Manual adjustment of the horizontal louver is discouraged, as it can cause the louver to go out of sync; if this happens, the unit should be powered off, unplugged for a few seconds, and then restarted.

For optimal operation, users are advised to:

Adjust airflow correctly to avoid directing it at people.
Set the temperature to moderate comfort levels, as excessively low or high temperatures waste energy.
Keep windows and doors closed to improve performance.
Use the TIMER function to limit energy usage.
Avoid placing objects near air inlets or outlets, as this can reduce efficiency and cause the unit to stop running.

Maintenance Features

Regular care and maintenance are crucial for the longevity and efficient operation of the air conditioner. Before any maintenance, the system must be turned off, and the power supply disconnected.

Cleaning the unit: The unit should be wiped with a soft, dry cloth. If it is very dirty, a cloth soaked in warm water can be used. Harsh cleaning agents such as chemically treated cloths, benzine, thinner, polishing powder, or similar solvents are prohibited, as they can crack, deform, or discolor the plastic surface. Water hotter than 40°C/104°F should not be used on the front panel to prevent deformation or discoloration.

Cleaning the air filter: A clogged air filter reduces cooling efficiency, so it should be cleaned every two weeks.

To access the filter, open the front panel by carefully lifting both ends until it clicks and remains open. Some models may require suspension bars to prop up the panel.
Use the provided tab to move the filter slightly upwards, then towards you, and finally extract it by gently pulling downwards.
If present, the small air freshening filter should be unclipped from the large air filter, cleaned with a vacuum, and replaced occasionally.

The manual also includes instructions for indoor and outdoor unit installation, emphasizing the need for a hard and firm wall for the indoor unit to prevent vibration. A mounting plate is fastened to the wall, ensuring it is level and secure. A wall-through hole for piping and cables should be made with a slight downward slant (5°-10°) and sealed with a pipe protecting ring and putty to prevent damage and rodent entry. The typical wall hole size is 60mm-80mm, and pre-buried power wires or hard walls should be avoided when making the hole. Instructions for connecting the pipe and cable are also provided, including details on pipe length and additional refrigerant requirements.
