Warranty Information
Refer to manufacturer or service agent for warranty information.
Operation Panel
The operation panel features a THERMOSTAT and a SELECTOR knob.
SELECTOR Knob Functions:
- HIGH FAN: Maximum air circulation without cooling.
- MED FAN: Middle speed air circulation without cooling.
- HIGH COOL: Automatic cooling with maximum air circulation.
- MED COOL: Automatic cooling with middle air circulation.
- LOW COOL: Automatic cooling with minimum air circulation.
- OFF: Completely shuts off the unit.
Note: When turning from LOW COOL to HIGH COOL, do so slowly. Avoid frequent changes between these two modes.
THERMOSTAT Knob Functions:
The thermostat automatically controls the compressor to maintain a set room temperature. It starts and stops cooling as needed for efficient and economical operation.
Operation Method: Turn the knob along the arrow for lower temperature settings. Turn the knob in the opposite direction if it becomes too cool, or towards "COOLER" if it is too hot.
Note: After turning the thermostat counterclockwise, wait at least three minutes before turning it back to "COOLER" to prevent potential overload.
Air Flow Adjustment
Horizontal Louver: Move the "T" shaped handle left or right.
Vertical Louver: Adjust any one of the horizontal louver blades.
Fresh Air Ventilation
The ventilation switch controls fresh air intake. "CLOSE" stops ventilation, "VENT" opens it. Keeping ventilation open reduces cooling efficiency.
Troubleshooting and error codes
| Problem | Possible Causes | What To Do |
|---|---|---|
| Air conditioner does not start | The air conditioner is unplugged. | Make sure the air conditioner plug is pushed completely into the outlet. |
| The fuse is blown/circuit breaker is tripped. | Check the house fuse/circuit breaker box and replace the fuse or reset the breaker. | |
| Power failure. | If power failure occurs, turn the air conditioner OFF. When power is restored, wait 3 minutes to restart the air conditioner to prevent tripping of the compressor overload. | |
| Air conditioner does not cool as it should | Airflow is restricted. | Make sure there are no curtains, blinds or furniture blocking the front of the air conditioner. |
| The temp control may not be set correctly. | On models with touch pads: In COOL mode, press the DECREASE▼pad. On models with control knobs, turn the temperature knob to a higher number. | |
| The air filter is dirty. | Clean the filter at least every 30 days. See the Operating Instructions section. | |
| The room may have been hot. | When the air conditioner is first turned on you need to allow time for the room to cool down. | |
| Cold air is escaping. | Check for open furnace and cold air returns. | |
| Cooling coils have iced up. | Set the air conditioner's vent to the closed. See "Air conditioner freezing up" below. | |
| Air conditioner freezing up | Ice blocks the air flow and stops the air conditioner from cooling the room. | On models with control knobs, set the mode control at HIGH FAN or HIGH COOL with the temp at 1 or 2. On models with touch pads, set the controls at HIGH (F3) FAN or HIGH (F3) COOL and set the thermostat to a higher temperature. |
| Water drips outside | Excessively hot and humid weather. | This is normal. |
| Water drips indoors | The air conditioner is not tilted to the outside. | For proper water disposal, make sure the air conditioner slants slightly from the case front to the rear. |
| Water collects in base pan | Moisture is removed from indoor air and drains into rear of a cabinet where a fan blows it against the outdoor condenser coil. | This is normal for a short period in areas with little humidity; normal for a longer period in very humid areas. |
| Normal Operating Sounds | (Various causes) | You may hear a pinging noise caused by water being picked up and thrown against the condenser on rainy days or when the humidity is high. This design feature helps remove moisture and improve efficiency. You may hear the thermostat click when the compressor cycles on and off. Water will collect in the base pan during high humidity or on rainy days. The water may overflow and drip from the outdoor side of the unit. The fan may run even when the compressor does not. |
