Installation Guide
Tools Needed:
- Drill with core bit
- Level
- Screwdrivers (flat and Phillips)
- Torque wrench
- Vacuum pump and gauge manifold
- Pipe cutter and flaring tool
Step-by-Step Installation
- Choose Installation Location: Select a location with proper wall support, away from direct sunlight and heat sources, with adequate clearance for airflow.
- Mount Indoor Unit Bracket: Secure the mounting bracket to the wall using appropriate anchors and ensure it is perfectly level.
- Prepare Refrigerant Pipes: Cut copper pipes to required length, flare the ends, and insulate with foam insulation sleeves.
- Drill Wall Hole: Drill a 65mm hole through the wall at a slight downward angle to the outside for drainage.
- Connect Pipes and Cables: Connect refrigerant pipes, drain hose, and electrical cables between indoor and outdoor units.
- Mount Indoor Unit: Hang the indoor unit on the mounting bracket and secure it properly.
- Vacuum and Charge: Evacuate air and moisture from the system using a vacuum pump, then release refrigerant according to specifications.
- Test Operation: Power on the unit and test all functions including cooling, heating, and fan modes.

Key Features
Inverter Technology
Advanced DC inverter compressor adjusts cooling/heating output precisely to maintain desired temperature with minimal energy consumption and temperature fluctuations.
3D i-See Sensor
Intelligent sensor detects human presence and movement, automatically directing airflow away from occupants for maximum comfort while optimizing energy usage.
Wide-angle Airflow
Multi-directional vanes provide wide-area cooling/heating coverage, ensuring even temperature distribution throughout the room without cold/hot spots.
Plasma Quad Filter
Four-stage filtration system removes dust, pollen, odors, and bacteria while deactivating viruses and allergens for cleaner, healthier indoor air.
Wi-Fi Control
Connect to home network for remote control via smartphone app, allowing scheduling, monitoring, and control from anywhere with internet access.
Eco-friendly R32 Refrigerant
Uses R32 refrigerant with lower global warming potential (GWP) compared to traditional refrigerants, reducing environmental impact by approximately 75%.
Operation Modes Explained
Auto Mode
Intelligently switches between cooling and heating based on room temperature for optimal comfort
Eco Mode
Reduces energy consumption by optimizing operation while maintaining comfort levels
Powerful Mode
Maximum cooling/heating capacity for rapid temperature adjustment when needed
Sleep Mode
Gradually adjusts temperature and reduces fan speed for undisturbed sleep
Dry Mode
Dehumidifies air without significant cooling, ideal for humid conditions
Fan Only Mode
Circulates air without cooling or heating for ventilation and air purification
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 issues | Clean filters, clear obstructions, check for leaks, ensure outdoor unit is operational |
| Water leaking indoors | Clogged drain pipe, improper installation slope, frozen evaporator | Clear drain pipe, ensure proper slope, check for ice buildup |
| Unusual noises | Loose parts, debris in fan, refrigerant flow noise | Tighten mounting, clear debris, check refrigerant charge |
| Foul odors | Dirty filters, mold growth in drain pan, stagnant water | Clean filters and drain pan, run fan mode to dry unit |
| Remote not working | Dead batteries, signal obstruction, sensor issues | Replace batteries, ensure line of sight, check indoor unit sensor |
Error Codes
