| Inverter Technology | Adjusts compressor speed for efficient cooling/heating and stable temperature |
| 3D Airflow | Wide-angle louvers for uniform air distribution throughout the room |
| Intelligent Eye Sensor | Detects human presence and adjusts operation to save energy |
| Operation Modes | Cool, Dry, Fan, Heat (on heat pump models), Auto |
| Air Purification | Built-in filters (e.g., PM2.5 filter, anti-allergy enzyme filter) |
| Quiet Operation | Low noise levels for both indoor and outdoor units |
| Wi-Fi Control | Remote control via smartphone app (on compatible models) |
| Self-Clean Function | Automatically dries indoor unit to prevent mold and odor |
| Timer Settings | 24-hour On/Off timer and weekly programming |
| Powerful Operation | Quick cooling/heating for fast room temperature adjustment |
Installation must be performed by a qualified technician. Unpack and verify all components.
WARNING! Incorrect installation can cause electric shock, fire, or equipment damage. Always hire a certified professional.
After installation, perform initial setup for optimal performance.
CAUTION! Allow at least 3 minutes after turning off before restarting to protect compressor.
Remote Control: POWER, MODE, TEMP ▲/▼, FAN SPEED, SWING, TIMER, SLEEP, LED ON/OFF, RESET FILTER, POWERFUL/QUIET buttons.
Indoor Unit Indicators: Operation LED (green), Timer LED (orange), Filter sign (red when cleaning needed).
Mode Selection: COOL (snowflake), DRY (water drop), FAN (fan icon), HEAT (sun icon), AUTO (automatically selects mode based on room temp). Fan Speed: Auto, High, Medium, Low, Silent. Swing: Adjust vertical/horizontal louvers. Timer: Set daily On/Off schedule. Sleep Mode: Gradually adjusts temperature for comfortable sleep. Powerful/Quiet: Turbo cooling/heating or ultra-quiet operation.
Intelligent Eye: When enabled, reduces fan speed or switches to energy-saving mode if no movement detected for 20 minutes. 3D Airflow: Wide-angle airflow mode for even distribution. Self-Clean Operation: Runs fan after cooling to dry heat exchanger and prevent mold (activate via remote). Wi-Fi Control: Connect to Daikin app for remote control, scheduling, and energy monitoring (setup via app instructions). Follow Me Function: Remote control acts as temperature sensor for precise control.
Regular maintenance ensures efficiency and longevity.
CAUTION! Always turn off power at circuit breaker before cleaning. Do not wash indoor unit with water.
Self-diagnosis function displays error codes on indoor unit LED or remote control.
| Code | Meaning | Action |
|---|---|---|
| E0 | Protection device activation | Check for obstructions; restart after 3 minutes |
| E3 | High pressure error | Check outdoor unit ventilation; clean condenser |
| E6 | Communication error | Check wiring between indoor/outdoor units |
| U4 | Indoor/outdoor communication | Inspect connection; reset power |
| H9 | Outdoor temperature sensor | Contact service technician |
| P1 | Voltage protection | Check power supply voltage |
Reset: Turn off at breaker for 10 minutes, then restart. If error persists, contact service.
Standard warranty: 1 year on parts, 5 years on compressor (varies by region). Registration may be required within 90 days of installation. Keep original receipt and installation certificate.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Unit does not start | Power supply, remote batteries | Check circuit breaker; replace remote batteries; ensure remote is pointed at unit. |
| Poor cooling/heating | Dirty filters, blocked airflow | Clean air filters; ensure outdoor unit is not obstructed; check temperature setting. |
| Water dripping indoors | Clogged drain pipe | Check drain hose for blockage; ensure proper slope. |
| Unusual noise | Loose parts, debris | Check for loose panels; remove debris from fan blades (outdoor unit). |
| Remote not working | Batteries, distance, obstacles | Replace batteries; operate within 7 meters; remove obstacles. |
| LED blinking | Error condition | Refer to Error Codes section; reset power. |
| Foul odor | Dirty filters, mold | Clean filters; run Fan mode for few hours; use self-clean function. |
Service: For persistent issues, contact authorized Daikin service center. Do not attempt to repair refrigerant system yourself.
