Installation Guide
Tools Needed:
- Adjustable wrench
- Level
- Screwdrivers (flat and Phillips)
- Pipe cutter
- Vacuum pump
- Manifold gauge
- Torque wrench
Step-by-Step Installation
- Choose Installation Location: Select a location with proper clearance (minimum 30cm from walls and ceilings) on a solid wall that can support the unit's weight.
- Mount Indoor Unit Bracket: Securely mount the mounting plate to the wall using appropriate anchors for your wall type.
- Install Outdoor Unit: Place outdoor unit on a stable, level surface with proper ventilation clearance (minimum 50cm on all sides).
- Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units, ensuring proper insulation and leak-free connections.
- Electrical Connection: Connect to a properly grounded 220-240V, 50Hz power supply with dedicated circuit breaker.
- Vacuum and Charge: Evacuate air and moisture from refrigerant lines using a vacuum pump, then charge with specified refrigerant amount.
- Test Run: Run the air conditioner in cooling and heating modes to check for proper operation and temperature performance.

Key Features
Inverter Technology
Advanced DC inverter compressor adjusts cooling/heating power precisely to maintain desired temperature, reducing energy consumption by up to 30% compared to conventional units.
3D i-See Sensor
Intelligent sensor detects human presence and movement, automatically directing airflow away from occupants for maximum comfort while optimizing energy efficiency.
Quiet Operation
Specialized noise reduction technology ensures ultra-quiet operation as low as 19 dB, quieter than a whisper, for undisturbed sleep and peaceful environment.
Wide-angle Airflow
Multi-directional vanes distribute air evenly throughout the room, eliminating hot/cold spots and ensuring consistent temperature in every corner.
Eco-friendly R32 Refrigerant
Uses R32 refrigerant with lower global warming potential (GWP) than conventional refrigerants, reducing environmental impact by approximately 75%.
Wi-Fi Connectivity
Built-in Wi-Fi allows remote control via smartphone app, enabling scheduling, monitoring energy usage, and receiving maintenance alerts from anywhere.
Advanced Operation Modes
Powerful Mode
Rapid cooling/heating to reach desired temperature quickly, then automatically switches to normal operation
Eco Mode
Optimizes energy consumption while maintaining comfort, reducing power usage by up to 40%
Sleep Mode
Gradually adjusts temperature and reduces fan speed for optimal sleeping conditions throughout the night
Dry Mode
Reduces humidity without overcooling the room, ideal for rainy seasons and damp environments
Auto Swing
Automatic vertical and horizontal airflow adjustment for even temperature distribution
I-Feel Control
Remote control acts as temperature sensor, ensuring optimal comfort at your exact location
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit won't start | Power issue, remote control batteries dead, circuit breaker tripped | Check power supply, replace remote batteries, reset circuit breaker |
| Poor cooling/heating | Dirty filters, blocked airflow, refrigerant leak, outdoor unit obstructed | Clean filters, clear obstructions, check for leaks, ensure outdoor unit ventilation |
| Water leaking indoors | Clogged drain pipe, improper installation, frozen evaporator | Clear drain pipe, check installation angle, defrost unit |
| Unusual noises | Loose parts, debris in fan, vibration from mounting | Tighten all screws, clear debris, check mounting stability |
| Foul odor | Dirty filters, mold growth in drain pan, accumulated dust | Clean filters and drain pan, use anti-bacterial treatment |
| Remote not working | Dead batteries, signal obstruction, remote sensor issue | Replace batteries, ensure line of sight, check remote sensor |
