This air conditioner uses R32 refrigerant, which is flammable. Installation and maintenance must be performed by qualified professionals. Ensure the room size meets the minimum area requirements specified in the manual. Before operation, ensure the power supply is correct and the unit is properly grounded. The remote controller allows for various modes including Cooling, Heating, Dry, and Fan, as well as special functions like I FEEL, Sleep, and Energy-saving.
Product Introduction
The system consists of an indoor unit with key components including the connection pipe, panel, air louver, swing blade, air-in grille, built-in filter, main body, drainage device, and drainage pipe. The unit is controlled via a remote controller.
Installation
Installation must be performed by qualified technicians. Installation Position Selection: Ensure the location can withstand the unit's weight, allows for convenient drainage, and is free from obstructions near the air inlet and outlet. Keep the unit away from heat sources, flammable gases, and ensure sufficient space for maintenance. Indoor Unit Installation: Drill holes according to the provided paper pattern, install expansion bolts, and suspend the unit securely. Refrigerant Pipe Connection: Use a torque wrench to tighten flaring nuts to the specified torque. Drainage Pipe Installation: Ensure a downward gradient of at least 1%-2% for smooth drainage. Do not connect to waste pipes or rain pipes. Panel Installation: Ensure there is no gap between the decoration panel and the ceiling board.
Operation
Remote Controller: Use the On/Off button to start/stop the unit. Select modes using the Mode button. Adjust fan speed and blowing angle using the Fan and Swing buttons. Special Functions: The I FEEL function adjusts temperature based on the remote controller's location. The Sleep function provides comfort during sleep. The Energy-saving function optimizes power consumption. The X-FAN function dries the indoor unit to prevent mold.
Maintenance
Routine Maintenance: Regularly check if the air inlet and outlet are blocked. Ensure the unit is securely grounded and power cords are connected. Cleaning: Turn off and unplug the unit before cleaning. Use a soft, dry cloth or a cloth with mild detergent for the outer case. Seasonal Maintenance: Before the season, check for blockages and grounding. After the season, run the unit in fan mode for half a day to dry the interior and cut off the power supply.
Troubleshooting
If the unit fails to start, check the power supply, leakage switch, and operating keys. If cooling/heating is poor, check for dirty filters, open doors/windows, or obstructions. Error codes such as E1 (Compressor high pressure protection), E6 (Communication error), and E9 (Full water protection) indicate specific issues requiring professional attention.
Safety
This appliance is not intended for use by children or persons with reduced capabilities without supervision. Do not repair the unit yourself. In case of refrigerant leakage, ventilate the room immediately and contact a service center.

Practical help
Common problems
Unit cannot be started
Check if the power supply is connected, the leakage switch has tripped, or if operating keys are locked.
Poor cooling or heating effect
Check for dirty or blocked air filters, open doors or windows, obstructions at air intake/outlet, or incorrect temperature settings.
Unit operates for a while and then stops
Check for obstacles in front of the condenser or if the outdoor ambient temperature is above 48°C (for cooling).
Refrigerant leakage
Immediately ventilate the room, ensure no fire sources are present, leave the area, and contact the after-sales service team.
