GENERAL

The indoor unit provides quiet, maximum comfort. It filters and dehumidifies the air for optimal comfort. Installation should be performed by authorized personnel. The system can be operated via the remote control or the "Auto" setting on the unit.

Operating Modes:

• FAN Only: Circulates room air without changing temperature.
• AUTO: Automatically cools or heats the room based on the set point. Recommended for single-zone applications.
• HEATING (Heat Pump models only): Heats and filters the room air.
• COOLING: Cools, dries, and filters the room air.
• DEHUMIDIFICATION (DRY): Dries, filters, and slightly cools the room air, prioritizing dehumidification.

Wireless Remote Control

The remote control transmits commands to operate the system and features a display panel showing the current system status. A mounting bracket is provided for securing the control.

Key Functions:

• ON/OFF: Turns the unit on or off.
• TEMP ▲/▼: Increases or decreases the temperature in 1°F (0.5°C) increments. Pressing both buttons together for 3 seconds alternates between °F and °C display.

• MODE: Selects operation mode (AUTO, COOL, DRY, HEAT, FAN).
• FAN SPEED: Selects fan speed (AU, 20%-100%).
• SWING: Starts and stops horizontal louver movement. Holding for 2 seconds initiates vertical auto swing.
• TIMER: Sets the timer to turn the unit on or off.
• ECO/GEAR: Enters energy-efficient modes (ECO, GEAR 75%, GEAR 50%).
• HUMIDITY: Adjusts room humidity (35%-85%) during DRY operation.
• LED: Turns the indoor unit's LED display and buzzer on/off.
• BOOST: Enables the unit to reach the preset temperature quickly.
• Occupancy Sensor: Detects human movement to conserve energy.
• OK: Confirms selected functions.

Remote Control Operation - Quick Start

To operate the unit:

1. Turn the unit on using ON/OFF.
2. Select the desired mode using MODE.
3. Set the temperature using TEMP ▲/▼.
4. Press FAN to select the fan speed.

Note: Fan speed is automatically set in DRY or AUTO modes.

Adjust airflow direction using SWING. For optimal performance:

• Keep doors and windows closed.
• Limit energy usage with TIMER ON/OFF functions.
• Do not block air inlets or outlets.
• Regularly inspect and clean air filters.

INDOOR UNIT DISPLAY

The indoor unit display window shows temperature, operation features, and error codes. Indicators may vary by model.

• 888: Displays temperature, operation features, and error codes.
• eco: Indicates ECO function is activated.
• (Wi-Fi symbol): Indicates Wireless Control feature is activated.
• ON (for 3s): Indicates TIMER ON is set or SWING, TURBO, ECO, BREEZE AWAY, SILENCE, or ECO INTELLIGENT EYE feature is turned on.
• OF (for 3s): Indicates TIMER OFF is set or SWING, TURBO, ECO, BREEZE AWAY, SILENCE, or ECO INTELLIGENT EYE feature is turned off.
• CL: Indicates Active Clean feature is turned on.
• df: Indicates defrosting.
• FP: Indicates 46°F (8°C) heating feature is turned on.

ADDITIONAL FEATURES

• Active Clean Function: Washes away dust by freezing and thawing frost, then drying with internal airflow. Display shows "CL" during operation and the unit turns off automatically after completion.
• ECO Intelligent Eye: Intelligently detects people's activities to save energy. It lowers unit frequency if no activity is detected for 30 minutes and resumes operation when activity is sensed.
• AUTO LEAK DETECTION: A refrigerant sensor detects leaks. If a leak is detected, the unit displays an error code and emits a buzzing sound. The compressor stops, and the indoor fan runs. The sensor has a 15-year service life and can only be replaced by the manufacturer.
• Auto-Restart: If power is lost, the unit automatically restarts with the previous settings once power is restored.
• Louver Angle Memory: The louver resumes its previous angle upon unit startup.
• Breeze Away: Avoids direct airflow on the body.
• Sleep: Decreases energy use during sleep. In COOL mode, temperature increases by 2°F (1°C) after 1 hour and another 2°F (1°C) after the second hour. In HEAT mode, temperature decreases by 2°F (1°C) after 1 hour and another 2°F (1°C) after the second hour. SLEEP stops after 8 hours.
• Wireless Control: Allows control via a smartphone with a wireless connection.
• Outdoor Unit Reverse Fan Operation: Helps keep the outdoor coil cleaner by running the fan in reverse for 70 seconds after the unit is turned off.

SETTING AIR FLOW

Use the SWING function on the remote control to set the vertical/horizontal angle of airflow. Avoid setting the louver at too vertical an angle, especially in COOL or DRY modes, to prevent condensation. Do not adjust the louver by hand; power cycle the unit if manual adjustment is needed.

CARE AND MAINTENANCE

CAUTION: Always turn off the unit and disconnect the power supply before cleaning or maintenance.

• Clean the air filter every two weeks for optimal cooling efficiency and health.
• Do not touch the air freshening (Plasma) filter for at least 10 minutes after turning off the unit.
• Use a soft, dry cloth for cleaning. A cloth dampened with warm water can be used for stubborn dirt. Do not use chemicals or solvents.
• Do not use water hotter than 104°F (40°C) for cleaning the front panel.

Cleaning Your Indoor Unit, Air Filter:

1. Open the front panel.
2. Pull the air filter upwards from the top.
3. If your filter has a small air freshening filter, unclip it and clean it with a vacuum cleaner.
4. Clean the large air filter with warm, soapy water and a mild detergent. Rinse with fresh water, shake off excess water, and dry in a cool, dry place away from direct sunlight.
5. Re-clip the air freshening filter and reinstall the large air filter.

Maintenance - Long Periods of Non-Use:

• Clean all filters.
• Turn on FAN function until the unit dries out completely.
• Turn off the unit and disconnect the power.
• Remove batteries from the remote control.

Maintenance - Pre-Season Use:

• Check for damaged wires.
• Clean all filters.
• Check for leaks.
• Ensure nothing is blocking air inlets and outlets.
• Replace batteries.

TROUBLESHOOTING

SAFETY PRECAUTIONS

If any of the following occur, turn off the unit immediately and contact an authorized service provider:

• Damaged or abnormally warm power cord.
• Burning odor.
• Loud or abnormal sounds.
• Power fuse blows or circuit breaker trips frequently.
• Water or other objects fall into or out of the unit.

Table 1 - Common Issues

• Unit does not turn on: 3-minute protection feature prevents overloading. Unit will restart after 3 minutes.
• Unit changes from COOL/HEAT to FAN: Unit may change settings to prevent frost formation. It will resume normal operation once the temperature increases.
• Indoor unit emits white mist: Normal in humid regions due to temperature difference.
• Both units emit white mist: May occur when the unit restarts in HEAT mode after defrosting, due to moisture.
• Indoor unit makes noises: Rushing air sound when louver resets; squeaking sound due to expansion/contraction of plastic parts.
• Both units make noises: Low hissing sound is normal, caused by refrigerant flow.
• Outdoor unit makes noises: Squeaking sound due to temperature changes.
• Dust emits from units: May occur after periods of non-use due to dust accumulation.
• Unit emits a bad odor: Unit may absorb odors from the environment, or filters may be moldy and require cleaning.
• Outdoor unit fan does not operate: Fan speed is controlled to optimize product operation.
• Operation is erratic/unpredictable/unresponsive: Interference from cell phone towers or boosters. Try power cycling or restarting with the remote.

Note: If an issue persists, contact a local dealer or customer service center with a detailed description of the malfunction and the unit's model number.

Table 2 - Troubleshooting Tips

• Poor Cooling Performance: Lower temperature setting; clean heat exchanger; clean air filter; remove obstructions from air inlet/outlet; close doors/windows; reduce heat sources.
• Unit is not working: Check for leaks and recharge refrigerant; turn off SILENCE function; restore power; replace fuse; wait for 3-minute protection to reset; turn timer off.
• Unit starts and stops frequently: Check refrigerant levels; evacuate and recharge system; ensure no incompressible gas or moisture; check for blocked circuits; replace compressor; regulate voltage; use auxiliary heating if outdoor temperature is extremely low.
• Poor heating performance: Close doors/windows; check for leaks and recharge refrigerant.
• Error code appears: Refer to Table 3 for error codes and indications. If codes EHC1 or EHC2 appear, call a technician. The unit may enter TURBO mode. A beeping noise is normal.
