|---|---|---|
| 280 | 280 | 280 |
| 200 | 200 | 200 |
| 96 | 96 | 48 |
| 96 | 96 | 24 |
| 40 | 40 | 12 |
| 16 | 16 | 12 |
Note: The specific model mapping to these charge values requires cross-referencing with detailed unit specifications not fully presented in a clear table format.
Operating Temperature Ranges
The document specifies operating conditions using Dry Bulb (DB) and Wet Bulb (WB) temperatures in Celsius (°C).
| Condition | DB/WB (°C) |
|---|---|
| Model Group (e.g., 09K/12K) | 32/23 |
| Model Group (e.g., 18K/24K) | 43/26 |
General operating temperature range mentioned: 18°C ~ 43°C.
Additional Technical Data
The PDF contains several tables with numerical data points that likely represent detailed performance metrics, efficiency ratings, or physical characteristics. These tables include values such as 1.2, 1.3, 14.5, 5.2, 1.6, 2.6, 1.4, 16.8, etc., often associated with units like kg, m, m², and N (Newtons). Due to the lack of clear headers and context for these specific tables, a precise transcription into a structured format is not feasible. They are indicative of comprehensive technical specifications.
Remote Control Functions
The remote control allows for various operating modes and settings:
- Power Button: [Power Symbol] Turns the unit on/off.
- I FEEL Button: ? Activates the "I FEEL" mode, which uses a sensor in the remote to detect room temperature and adjust operation accordingly.
- TURBO Button: ? Selects the TURBO mode for rapid cooling or heating.
- X-FAN Button: ?️ Enables the X-FAN function, which keeps the indoor fan running after shutdown to dry the indoor unit.
- MODE Button: ⚙️ Cycles through operating modes: AUTO, COOL, DRY, FAN, HEAT.
- FAN Button: ?️ Adjusts the fan speed: AUTO, LOW, MEDIUM, HIGH.
- TEMP Buttons: ?️ Adjusts the target temperature.
- CLOCK Button: ? Sets the clock for the remote control.
- TIMER ON/OFF Buttons: ⏰ / ?⏰ Used to set or cancel the timer functions for turning the unit on or off at a specific time.
The document details specific button combinations and sequences for setting timers and other functions, often involving pressing buttons within a certain timeframe.
Installation Guide Summary
Proper installation is crucial for optimal performance and safety. Key steps include:
- Indoor Unit Mounting: Securely mount the indoor unit on a wall using the provided mounting bracket. Ensure adequate clearance for airflow and maintenance.
- Outdoor Unit Placement: Install the outdoor unit on a stable, level surface, away from direct sunlight and obstructions, ensuring proper ventilation.
- Refrigerant Piping: Connect the copper refrigerant pipes between the indoor and outdoor units. Ensure correct pipe sizes are used according to the unit's capacity.
- Electrical Wiring: Connect the power supply and control wiring according to the wiring diagram and local electrical codes. Ensure proper grounding.
- Drainage: Connect the drain hose from the indoor unit to ensure condensate water is properly removed.
- Vacuuming and Leak Testing: Evacuate the refrigerant lines using a vacuum pump to remove air and moisture. Perform a leak test on the system.
- System Charging: If necessary, charge the system with the correct amount of R32 refrigerant.
- Final Checks: Ensure all connections are secure, the unit is level, and there are no obstructions.
Torque Specifications: Specific torque values (N.m) are provided for various connections during installation, ranging from 15-20 N.m to 70-75 N.m, depending on the component size (e.g., pipe flare nuts).
Safety Precautions: The document emphasizes safety, including handling refrigerant (R32), electrical safety, and ensuring proper ventilation. A note mentions LFL (Lower Flammable Limit) of 25% for R32, indicating it is a flammable refrigerant.
