Usage Features:
The air conditioner is controlled via a remote control unit.
- Basic Operation:
- ON/OFF: Press the "OFF/ON" button to start/stop the unit.
- Mode Selection: Use the "MODE" button to select AUTO, HEAT, COOL, DRY, or FAN modes.
- In AUTO mode, the unit selects an operation mode based on room temperature (every 10 minutes for single-split, every 3 hours for multi-split).
- In HEAT mode, the POWER indicator blinks during initial warm-up.
- Temperature Setting: Use "TEMP UP" and "TEMP DOWN" buttons to adjust the desired temperature. Recommended energy-saving ranges are 20.0 °C ~ 24.0 °C (68 °F ~ 75 °F) for HEAT and 26.0 °C ~ 28.0 °C (79 °F ~ 82 °F) for COOL.
- Airflow Direction:
- The remote control allows adjustment of both upper/down and lateral airflow directions.
- In COOL/DRY mode, the horizontal flap swings automatically and fixes at an upper position once the temperature is achieved.
- In HEAT mode, the horizontal flap is fixed at a predetermined position, and the vertical flap swings left/right as temperature rises.
- Do not manually adjust the flap.
- Fan Speed and Quiet Condition:
- FAN SPEED: When AUTO FAN is selected, the fan speed adjusts automatically. Users can also select specific fan speeds.
- QUIET: This operation reduces airflow noise.
- POWERFUL/ECO Modes:
- POWERFUL: Quickly reaches the desired temperature (stops automatically after 20 minutes).
- ECO: Reduces power consumption for energy saving without sacrificing comfort.
- Sleep Mode: Maximizes comfort while sleeping by automatically adjusting the sleep pattern temperature during activation. The indoor unit indicator dims, and the operation is activated for 0.5, 1, 2, 3, 4, 5, 6, 7, 8, or 9 hours.
- Timer Setting: Allows users to set an ON or OFF timer for the unit at 2 different preset times.
- Remote Control Features: The remote control has indicators for POWER, TIMER, and ECO. It also includes buttons for SET, CHECK, CLOCK, and RESET. The remote control can be restored to default settings by pressing the "RESET" button.
Maintenance Features:
Regular cleaning and maintenance are essential for optimal performance and longevity of the air conditioner.
- Indoor Unit:
- Front Panel: Wash gently and dry. To remove the front panel, raise it up, slide the front panel to the right, and pull it out. Match and push in to close.
- Air Filters: Clean once every 2 weeks. Wash/rinse the filters gently with water to avoid damaging the surface. Dry the filters thoroughly under shade, away from direct sunlight. Replace any damaged filters.
- Anti-bacterial Filter: Clean whenever necessary by washing/rinsing gently with water. Dry thoroughly under shade. Replace every 10 years or any damaged filter (Part no.: CZ-SA22P).
