Step-by-Step Installation

  1. Choose Installation Location: Select a location with proper clearance (at least 15cm from ceiling and walls) on a solid wall that can support the unit's weight.
  2. Mount Indoor Unit: Install mounting plate securely to wall using provided screws and anchors. Ensure unit is level.
  3. Install Outdoor Unit: Place outdoor unit on a stable, level surface with proper ventilation clearance (minimum 30cm on all sides).
  4. Connect Refrigerant Pipes: Connect copper pipes between indoor and outdoor units. Ensure all connections are tight and properly insulated.
  5. Connect Drain Hose: Route drain hose with a downward slope to ensure proper drainage. Use insulation on drain pipe in cold areas.
  6. Electrical Connection: Connect to a properly grounded 220-240V, 50Hz power supply. Follow local electrical codes.
  7. Vacuum and Charge: Evacuate air and moisture from refrigerant lines using vacuum pump, then release refrigerant charge.
  8. Test Run: Test all functions including cooling, heating, fan speeds, and remote control operation.
Warning: Installation must be performed by a qualified HVAC technician. Incorrect installation may cause water leakage, electrical shock, or fire.
