Function Description

The Comfee Split-Type Room Air Conditioner is designed to provide cooling, heating, and dehumidification for indoor spaces. It consists of an indoor unit and an outdoor unit connected by refrigerant piping and electrical cables. The unit can be controlled via a remote control (some units include a remote control holder) and, for some models, wirelessly via a mobile phone.

Operating Modes: The air conditioner supports COOL, HEAT, and DRY modes.

COOL mode: Operates within a room temperature range of 17°C - 32°C (62°F - 90°F). Outdoor temperature ranges vary by model type:
- Inverter Split Type: 0°C - 50°C (32°F - 122°F); -15°C - 50°C (5°F - 122°F) for low temp. cooling systems; 0°C - 52°C (32°F - 126°F) for special tropical models.
- Fixed-speed Type: 18°C - 43°C (64°F - 109°F); -7°C - 43°C (19°F - 109°F) for low-temp cooling systems; 18°C - 52°C (64°F - 126°F) for special tropical models.
HEAT mode: Operates within a room temperature range of 0°C - 30°C (32°F - 86°F). Outdoor temperature ranges vary by model type:
- Inverter Split Type: -15°C - 30°C (5°F - 86°F).
- Fixed-speed Type: 0°C - 30°C (32°F - 86°F); -7°C - 24°C (19°F - 75°F) for low-temp cooling systems; 18°C - 52°C (64°F - 126°F) for special tropical models.
DRY mode: Operates within a room temperature range of 10°C - 32°C (50°F - 90°F). Outdoor temperature ranges vary by model type:
- Inverter Split Type: 0°C - 50°C (32°F - 122°F); 0°C - 52°C (32°F - 126°F) for special tropical models.

Important Technical Specifications

Refrigerant Types: The units may use R32 or R290 refrigerants. For R32 and R290 models, only blast-proof ceramic fuses can be used.

R32 refrigerant models: Appliance must be installed, operated, and stored in a room with a floor area larger than 4m².
R290 refrigerant models: Appliance must be installed, operated, and stored in a room with a floor area larger than:
- <=9000Btu/h units: 13m²
- 9000Btu/h and <=12000Btu/h units: 17m²
- 12000Btu/h and <=18000Btu/h units: 26m²
- 18000Btu/h and <=24000Btu/h units: 35m²
- Reusable mechanical connectors and flared joints are not allowed indoors (EN Standard Requirements).
- Mechanical connectors used indoors shall have a rate of not more than 3g/year at 25% of the maximum allowable pressure. Sealing parts must be renewed if connectors are reused. Flare parts must be re-fabricated if flared joints are reused (UL Standard Requirements).
- Mechanical connectors used indoors must comply with ISO 14903.
- Total amount of R290 refrigerant to be charged is limited: 387g (<=9000Btu/h), 447g (>9000Btu/h and <=12000Btu/h), 547g (>12000Btu/h and <=18000Btu/h), 632g (>18000Btu/h and <=24000Btu/h).
- Mixing refrigerant types is prohibited.

Fuse Specifications: The air conditioner's circuit board (PCB) includes a fuse for overcurrent protection. Fuse specifications are printed on the PCB (e.g., T3.15AL/250VAC, T5AL/250VAC, T3.15A/250VAC, T5A/250VAC, T20A/250VAC, T30A/250VAC).

Electrical Connections:

All wiring must comply with local and national electrical codes and regulations.
Power voltage should be within 90-110% of rated voltage.
If connecting to fixed wiring, a surge protector and main power switch are required. An all-pole disconnection device with at least 3mm clearances in all poles and a residual current device (RCD) with a rated residual operating current not exceeding 30mA must be incorporated.
Minimum cross-sectional area of power and signal cables (for reference, not applicable for North America) is provided based on rated current (e.g., >3 and ≤6A requires 0.75mm², >32 and ≤40A requires 6mm²).
For North America, cable type and size should follow local electrical codes and Minimum Circuit Ampacity on the nameplate.

Refrigerant Piping:

Minimum pipe run of 3 meters is required to minimize vibration and excessive noise.
Maximum length and drop height of refrigerant piping vary by model capacity:
- <15,000 BTU/h: Max. Length 25m (82ft), Max. Drop Height 10m (33ft).
- ≥15,000 and <24,000 BTU/h: Max. Length 30m (98.5ft), Max. Drop Height 20m (66ft).
- ≥24,000 and <36,000 BTU/h: Max. Length 50m (164ft), Max. Drop Height 25m (82ft).
For R290 refrigerant models, the maximum length of refrigerant pipe should not exceed 10 meters (32.8ft).
Additional refrigerant charging is calculated based on pipe length and refrigerant type (R32, R290, R410A, R22).
Minimum bend radius for connective refrigerant piping is 10cm.

European Disposal Guidelines:

Waste electrical and electronic equipment should not be mixed with general household waste.
Dispose of at designated municipal electronic waste collection facilities.
Retailers will take back old appliances when a new one is purchased.
Manufacturers will take back old appliances free of charge.
Appliances can be sold to certified scrap metal dealers.
Improper disposal in natural surroundings can endanger health and the environment due to hazardous substances leaking into groundwater and entering the food chain.
