Installation Guide
Tools Needed:
- Refrigerant manifold gauge set
- Vacuum pump
- Leak detector
- Multimeter
- Pipe cutter and flaring tool
- Torque wrench
- Insulation tape
Step-by-Step Installation
- Site Preparation: Select a location with proper clearance for airflow and service access. Ensure mounting surface is level and sturdy.
- Mounting Unit: Secure outdoor condenser unit on a concrete pad or wall brackets. Install indoor unit according to mounting template.
- Refrigerant Line Installation: Connect copper refrigerant lines between indoor and outdoor units. Ensure proper insulation on suction line.
- Electrical Connections: Connect power supply to disconnect box. Follow local electrical codes for proper grounding and circuit protection.
- Drain Line Installation: Install condensate drain line with proper slope (1/4" per foot minimum) and trap where required.
- Vacuum and Charge: Evacuate system to 500 microns or less. Charge with specified refrigerant type and quantity.
- System Startup: Power up system and test all modes (cooling, heating, fan). Verify proper operation and temperature differentials.

Key Features
Inverter Technology
Variable speed compressor adjusts output to match exact cooling/heating demands, providing consistent temperatures and up to 40% energy savings.
Heat Pump Operation
Provides both heating and cooling from a single system. Efficiently extracts heat from outdoor air even in cold temperatures.
Wi-Fi Connectivity
Built-in Wi-Fi allows remote control via smartphone app. Monitor energy usage, adjust temperatures, and receive maintenance alerts.
Quiet Operation
Sound-dampening technology and vibration isolation keep indoor noise below 35 dB. Outdoor unit features low-noise fan design.
Air Purification System
Multi-stage filtration with HEPA filter, activated carbon, and UV-C light reduces allergens, odors, and airborne pathogens.
Auto Clean Function
Automatically dries indoor coil after use to prevent mold and mildew growth, maintaining air quality and system efficiency.
Operating Modes Explained
Cool Mode
Standard air conditioning operation with temperature and fan speed control
Heat Mode
Heat pump operation for efficient heating during mild to cold weather
Auto Mode
System automatically switches between heating and cooling based on room temperature
Dry Mode
Dehumidification without significant cooling, ideal for humid conditions
Fan Only
Circulates air without heating or cooling, with multiple speed options
Sleep Mode
Gradually adjusts temperature for optimal sleeping conditions and energy savings
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System not turning on | Power loss, tripped breaker, faulty thermostat | Check power supply, reset breaker, verify thermostat settings |
| Insufficient cooling/heating | Dirty filters, low refrigerant, blocked airflow | Clean filters, check refrigerant charge, clear obstructions |
| System freezing up | Low airflow, dirty coils, low refrigerant | Check filters and fans, clean coils, verify refrigerant level |
| Water leakage | Clogged drain line, improper slope, pump failure | Clear drain line, ensure proper slope, check condensate pump |
| Unusual noises | Loose parts, fan obstruction, compressor issues | Tighten mounting hardware, clear fan area, check compressor |
| High energy consumption | Dirty coils, incorrect sizing, thermostat issues | Clean coils, verify system sizing, calibrate thermostat |
