The TECO Inverter Split Type Air Conditioner, models LS/LT2705V and LS/LT3505V, is designed to provide efficient and comfortable climate control. This user's manual outlines its functions, features, and maintenance procedures to ensure satisfactory operation.

Function Description:

This air conditioner operates as an inverter split type system, capable of cooling, heating, dehumidifying, and fan-only operation. It utilizes a world-famous compressor and a microcomputer controlling chip for stable and reliable performance. High-efficiency components, including the compressor and heat exchanger, contribute to its energy-saving capabilities. For quiet operation, it incorporates a random pitch fan, a large fan wheel, and a stepping motor to drive the indoor fan. The system also employs fuzzy logic to optimize energy consumption and create a comfortable environment.

Important Technical Specifications:

While specific technical specifications like BTU ratings or power consumption are not detailed in the provided pages, the manual highlights key operational aspects. The temperature setting range is from 16°C to 30°C. The timer function allows for setting operations from 0:00 to 23:59. The unit features an auto-restart mode, which can be enabled or canceled by the user, allowing the air conditioner to resume its previous settings after a power interruption. The remote controller displays various operational modes, temperature settings, air speed, present time, signal transmission, air direction, sleep timer, one-hour setting, turbo boost, lock display, and timer settings.

Usage Features:

The air conditioner is controlled via a remote controller, which transmits signals to the indoor unit.

Mode Selection: Users can choose between Auto, Cooling, Dehumidifying, Heating, and Fan modes using the MODE button.
Temperature Adjustment: The TEMP buttons allow for precise temperature setting within the 16°C to 30°C range. Each press adjusts the temperature by 1°C.
Air Speed Control: The SPEED button regulates the fan speed, offering Low, Medium, High, and Auto options.
Air Direction Adjustment: The SWING button controls the horizontal air direction guide board, allowing it to swing up and down or remain static at a desired angle. Vertical air direction can be manually adjusted.
Timer Functions: The TIME SET button allows users to set the present time, as well as ON and OFF timers. A 1HR button provides a quick one-hour setting to turn off the unit.
Sleep Mode: The SLEEP button activates a comfortable sleep environment. In cooling mode, the fan speed automatically lowers, and the set temperature rises. In heating mode, the fan speed lowers, and the set temperature decreases.
Turbo Mode: The TURBO button enables fast cooling or heating, quickly adjusting the room temperature. This mode typically runs for 15 minutes at maximum wind speed before reverting to a pre-set mode.
Emergency Operation: In case of remote controller malfunction, the unit can be operated via an emergency switch on the indoor unit. This sets the temperature to 24°C and fan speed to AUTO.
Lock Display: A LOCK button is present on the remote controller, though its specific function is noted as "Not Functional" in the diagram.
Resetting: A RESET button on the remote controller allows the unit to be returned to its original settings.

Maintenance Features:

Regular maintenance is crucial for the air conditioner's longevity and efficient operation.

Air Filter Cleaning: The air filters should be cleaned at least 1-2 times per month. This involves removing the front cover, gently pulling out the main filters, and cleaning them with a vacuum cleaner or water. They should be dried in the shade before reinstallation.
Charcoal Filter Replacement: If fitted, charcoal filters cannot be washed and must be replaced every 3-6 months, depending on usage. New filters can be purchased from service agents. The manual provides instructions for removing and attaching these filters.
Remote Controller Cleaning: The remote controller can be cleaned by dipping a cloth in cold or warm water (under 40°C), wringing it out, and gently rubbing the unit.
Intake Vent Grille Cleaning: The intake vent grille should be washed with soft materials like a sponge and dried. For stubborn dirt, a neutral detergent solution can be used.
Long-Term Storage: When the unit will not be used for an extended period, it should be run to dry the inside, the power plug should be removed (or power turned off), and the batteries should be taken out of the remote controller.
Outdoor Unit Maintenance: The dirt between the fins of the outdoor heat exchanger should be cleaned regularly. Users are cautioned to cut off the power supply before cleaning and to be careful to avoid injury from the fins.

Safety Precautions:

The manual emphasizes several safety precautions:

Installation and repair must be performed by qualified professional technicians in compliance with Australian regulations.
The air conditioner must be earthed.
The power plug should be removed (or power turned off) when not in use, especially during seasonal changes or thunderstorms.
Do not touch or operate the unit with wet hands.
Avoid prolonged direct airflow.
Do not insert objects into the unit.
Do not attempt to repair the unit yourself; contact Teco.
Do not damage the power cord. If damaged, it must be replaced by the manufacturer, service agent, or a qualified electrician.
Do not stop the unit by pulling out the power plug.
Children should not play with or sit on the air conditioner.
Ensure proper ventilation when in use.
If abnormal conditions (e.g., burnt smell) occur, switch off the unit and remove the power plug.
Do not use the unit for purposes other than its intended function.
Do not pull the power plug by pulling the cord.
Avoid splashing water on the unit.
Keep heaters away from the air conditioner to prevent deformation or discoloration.
Do not block air intake and outlet vanes.
Avoid overloading the air conditioner for extended periods (e.g., very high outdoor temperatures or open doors/windows).
Do not operate without the air filter installed or with the front intake grille removed.
Do not place anything on the unit.
Pull out the power plug or turn off the main switch before cleaning.

The manual also provides a troubleshooting guide for common issues, such as the unit not working, compressor stopping, low heating/cooling efficiency, noise, and remote controller display abnormalities. It advises users to check simple solutions before calling a serviceman.
