- 387g (<=9000Btu/h)
- 447g (>9000Btu/h and <=12000Btu/h)
- 547g (>12000Btu/h and <=18000Btu/h)
- 632g (>18000Btu/h and <=24000Btu/h)
Electrical Specifications:
- The air conditioner's circuit board (PCB) is designed with a fuse to provide overcurrent protection. The specifications of the fuse are printed on the circuit board.
- Indoor unit: 3.15A/250VAC, T5A/250VAC, T3.15A/250VAC, T5A/250VAC, etc. (e.g., 9000Btu/h, 12000Btu/h, 18000Btu/h units).
- Outdoor unit: 120A/250VAC (<=18000Btu/h units), T30A/250VAC (<=18000Btu/h units).
- Power Cable: H05VV-F or H05V2V2-F (Indoor), H07RN-F (Outdoor).
- Signal Cable: H07RN-F.
- Minimum cross-sectional area of power and signal cables are specified based on rated current of appliance (A):
-
3 and <=6 A: 0.75 mm²
-
6 and <=10 A: 1 mm²
-
10 and <=16 A: 1.5 mm²
-
16 and <=25 A: 2.5 mm²
-
25 and <=32 A: 4 mm²
-
32 and <=40 A: 6 mm²
Refrigerant Piping Length:
The maximum length of refrigerant piping affects performance and energy efficiency. For a standard pipe length of 5 meters (16.5ft) in North America, and 3 meters in other regions, the refrigerant charge is sufficient. For R290 refrigerant models, no refrigerant can be added, and the maximum length of refrigerant pipe should not exceed 10 meters (32.8ft).
Maximum length and drop height of refrigerant piping per unit model are provided in a table based on capacity (BTU/h).
Mounting Plate Dimensions:
Different models have different mounting plates. The manual provides diagrams and dimensions for various mounting plate types (Type A, B, C, D, E). The gas side connective pipe diameter is specified as Φ16mm (5/8in) or more, and the wall hole should be 90mm (3.54in).
Outdoor Unit Dimensions and Mounting Distances:
A table provides outdoor unit dimensions (W x H x D) and corresponding mounting distances (A and B) for various models.
Usage Features
Display Codes:
The indoor unit display shows various codes and indicators:
- "ECO" when ECO function is activated.
- "C" when lights up in different color according to the operation mode (some units).
- " " when Wireless Control feature is activated (some units).
- "88" displays temperature, operation feature, and error codes:
- "ON" for 3 seconds when TIMER ON is set.
- "OFF" for 3 seconds when TIMER OFF is set.
- "CF" when anti-cold air feature is turned on.
- "dF" when defrosting (cooling & heating units).
- "SC" when unit is self-cleaning.

- Close the front panel of the indoor unit.
- Do not touch air freshening (Plasma) filter for at least 10 minutes after turning off the unit.
Cleaning Your Air Filter:
- A clogged air conditioner can reduce efficiency. Clean the filter every two weeks.
- Lift the front panel of the indoor unit.
- Grip the tab on the end of the filter, lift it up, then pull it towards yourself.
- Pull out the filter.
- If your filter has a small air freshening filter, unclip it from the larger filter. Clean this air freshening filter with a hand-held vacuum.
- Clean the large air filter with warm, soapy water. Be sure to use a mild detergent.
