This document is a user manual for a Kolin window-type air conditioner, model KAM-55CMC32. It provides essential information for safe operation, installation, maintenance, and troubleshooting of the appliance.
Function Description
The Kolin KAM-55CMC32 is a window-type air conditioner designed to cool a single room. It operates by drawing in room air, cooling it, and then recirculating the cooled air. The unit features a "COOL MODE" for active cooling and a "FAN MODE" for air circulation without cooling. The thermostat allows users to set a desired room temperature, and the compressor will cycle on and off automatically to maintain this setting. Air directional louvers enable users to adjust the airflow direction (left or right) within the room. Some models may include an "Auto-Restart" function, which automatically resumes operation with previous settings after a power cut. A 3-minute delay is implemented after stopping the unit or changing modes (cool to fan and back to cool) to protect the compressor from overheating or circuit breaker tripping.
Important Technical Specifications
The manual provides operating temperature ranges for both cooling and heating operations, although the KAM-55CMC32 is specifically a window-type air conditioner, primarily for cooling.
- Cooling Operation:
- Outdoor temperature: 18-43°C (64-109°F), or 18-52°C (64-125°F) for special tropical models.
- Indoor temperature: 17-32°C (62-90°F).
- Heating Operation: (Note: This unit is a window-type air conditioner, primarily for cooling. Heating specifications might be for other models or general information.)
- Outdoor temperature: -5-24°C (23-76°F).
- Indoor temperature: 0-27°C (32-80°F).
- Unit Dimensions (W x H x D):
- For models <7000 Btu/h: 406x306x335 mm or 406x306x390 mm or 471x340x400 mm.
- For models ≥7000 Btu/h: 471x340x400 mm.
- The value of D (depth) is for reference only.
- Minimum Nominal Cross-Sectional Area of Conductors:
- Rated current of appliance (A) ≤ 6: 0.75 mm²
- Rated current of appliance (A) > 6 and ≤ 10: 1 mm²
- Rated current of appliance (A) > 10 and ≤ 16: 1.5 mm²
- Rated current of appliance (A) > 16 and ≤ 25: 2.5 mm²
- Suggested Minimum Wire Size (AWG: American Wire Gage):
- Appliance Amps 10: AWG Wire Size 18
- Appliance Amps 13: AWG Wire Size 16
- Appliance Amps 18: AWG Wire Size 14
- Appliance Amps 25: AWG Wire Size 12
- Appliance Amps 30: AWG Wire Size 10
- Refrigerant: The manual mentions R290/R32 refrigerant, indicating that the unit may use flammable refrigerants. Specific warnings and handling instructions are provided for these types of refrigerants. Fluorinated greenhouse gases are contained in hermetically sealed equipment.
Usage Features
- Control Panel: The unit features a rotary knob control panel.
- Cool Mode: Users can select "HI COOL" for maximum cooling and airflow or "LO COOL" for minimum cooling and airflow.
- Fan Mode: Allows selection of fan speeds for air circulation without engaging the compressor.
- Thermostat: A rotary switch to set the desired room temperature. The compressor automatically starts and stops to maintain the set temperature. Rotating clockwise provides lower room temperatures (higher cool settings), and counter-clockwise provides higher room temperatures (lower cool settings).
- Air Directional Louvers: A center handle allows users to adjust the airflow direction left or right.
- Auto-Restart (on some models): Automatically restarts the unit with previous settings after a power interruption.
- Compressor Protection: A 3-minute delay is enforced before restarting the unit or changing between cool and fan modes to protect the compressor.
Maintenance Features
- Air Filter Cleaning: The air filter should be checked at least once a month. It can be removed by sliding it out from the right-hand side. Cleaning involves washing with liquid dishwashing detergent and warm water, rinsing thoroughly, and drying completely, or vacuuming. Operating the unit without the air filter is strongly discouraged as dust and dirt can lead to equipment failure.
- Cabinet Cleaning: The cabinet and front can be dusted with an oil-free cloth or washed with a cloth dampened in a solution of warm water and mild liquid dishwashing detergent. Harsh cleaners, wax, or polish should not be used. Care must be taken to wring excess water from the cloth when cleaning around controls to prevent damage.
- Winter Storage: If storing the air conditioner during winter, it should be carefully removed from the window, covered with plastic, or returned to its original carton.
- Professional Servicing: Installation, service, maintenance, and repair of the unit, especially those involving fluorinated greenhouse gases or flammable refrigerants, must be performed by a certified technician.
- Troubleshooting Guide: The manual includes a troubleshooting section to help users identify and resolve common issues like the unit not starting, not cooling effectively, or freezing up. It provides possible causes and recommended actions, such as checking the power plug, circuit breaker, air filter, and ensuring proper airflow.
