Installation Requirements

Installation must be performed by a qualified technician. Unpack and verify all components.

  1. Select location: Install indoor unit on sturdy wall, away from direct sunlight and heat sources. Outdoor unit placed on stable surface with proper ventilation.
  2. Electrical connection: Ensure power supply matches unit specifications (e.g., 220-240V, 50Hz). Use dedicated circuit with proper grounding.
  3. Refrigerant piping: Connect copper pipes between indoor and outdoor units following length and bend radius specifications.
  4. Drain hose: Install with downward slope to ensure proper condensation drainage.
  5. Vacuum and leak test: Evacuate air from refrigerant lines and check for leaks before releasing refrigerant.

WARNING! Incorrect installation can cause electric shock, fire, or equipment damage. Always hire a certified professional.

First-Time Setup & Operation

After installation, perform initial setup for optimal performance.

  1. Power on: Plug in and turn on circuit breaker. Indoor unit will beep and display standby indicator.
  2. Remote control: Insert batteries (typically AAA). Point remote at indoor unit signal receiver.
  3. Test operation: Press POWER button on remote. Select desired mode (e.g., Cool). Set temperature using ▲/▼ buttons.
  4. Adjust airflow: Use SWING button to set louver direction and FAN button to adjust fan speed.
  5. Timer setting: Press TIMER button to program automatic On/Off times.

CAUTION! Allow at least 3 minutes after turning off before restarting to protect compressor.
