Split Air Conditioner and Residential Air Conditioners
| Error Codes | Meaning |
|---|---|
| C5 | Malfunction of connector jumper: Check if the connector jumper contacts properly. If the PCB is to be replaced, please take off the old for the new PCB. |
| F1 | Malfunction of indoor ambient temperature sensor :Check if indoor room temperature sensor is connected properly. |
| F2 | Malfunction of evaporator temperature sensor :Check if the evaporator temperature is connected properly. |
| H6 | Indoor fan block:Check if the terminal of the indoor motor is connected properly./Replace the fan motor or the indoor board if disabled. |
| H1 | Defrosting: It is normal. |
Buttons on the cover is unavailable or insensitive: Please check whether the cover is closed completely
Moisture on air outlet : If the unit operates at high humidity for a long time, moisture will be generated on the air outlet grill and then drip off.
Noise from indoor unit: The noise emitted when the fan or compressor relay is switching on or off./When the defrosting operation is started or stopped, there is a sound of refrigerant flowing in the reverse direction.
Troubleshooting
The air conditioner is not user serviceable.Incorrect repair may cause electric shock or fire so please contact an authorized service center for professional repair. Following checks prior to contact may save your time and money.
Phenomenon: The unit does not operate
Troubleshooting: The unit does not operate if it is turned on immediately after it is turned off. This is to protect the unit. You should wait about 3 minutes.
Phenomenon: Odours are emitted
Troubleshooting:
- Some odours may be emitted from the indoor unit. This is the result of room smells (such as furniture,tobacco,ect.) which have been taken into the air conditioner.
- Consult authorized service center for cleaning if the odours still exist.
Phenomenon: Water flowing” noise
Troubleshooting: The swishing noise like water flowing is the refrigerant flowing inside the unit.
Phenomenon: Mist is emitted in COOL mode
Troubleshooting: During cooling operation, a thin mist may be seen emitted from the indoor unit due to high room temperature and humidity. After a period of time, the mist will disappear with the decrease of room temperature and humidity.
Phenomenon: Cracking noise
Troubleshooting: This is the sound of friction caused by expansion and/or contraction of panel or other parts due to the change of temperature
Phenomenon: The unit can not be started up
Troubleshooting:
- Is the power cut off?
- Is the power plug loose? ( if applicable )
- Is the circuit protection device tripped off?
- Is voltage higher or lower? (Tested by professionals)
- Is the TIMER correctly used?
Phenomenon: Cooling/Heating effect is poor
Troubleshooting:
- Is temperature setting appropriate?
- Is the inlet or outlet blocked?
- Is the filter dirty?
- Is the window or the door open?
- Is low fan speed set?
- Are there heat sources in the room?
Phenomenon: Remote controller is not available
Troubleshooting:
- Check if there is magnetic or electrical interference near the unit that may affecting operation of the controller. In this case, pull the plug out and reinsert it.
- Is the remote controller within its operating range or obstructed? Check the condition of the batteries and replace them if necessary. Check if the remote controller is damaged.
Phenomenon: Water leakage of indoor unit
Troubleshooting:
- The humidity is high.
- Condensing water overflows.
- Drain hose is loose.
Phenomenon: Water leakage of outdoor unit
Troubleshooting:
- During cooling operation, water condensate is generated around the pipes and connection joints.
- During defrosting operation,the thaw water flows out.
- During heating operation,the water on the heat exchanger drips out
Phenomenon: Noise from indoor unit.
Troubleshooting:
- The noise emitted when the fan or compressor relay is switching on or off.
- When the defrosting operation is started or stopped, there is a sound of refrigerant flowing in the reverse direction.
Phenomenon: Indoor unit can not blow air
Troubleshooting:
- In HEAT mode, when the temperature of indoor heat exchanger is very low, air flow is stopped in order to prevent cold air. (Within 2 minutes)
- In HEAT mode, when the outdoor temperature is low or humidity is high, frost will be formed on the outdoor heat exchanger. The unit will defrost automatically and indoor unit will stop blowing air for 3-12 minutes.
- During defrosting operation, water or vapour may be emitted.
- In DRY mode, the indoor fan will stop blowing air for 3-12 minutes in order to avoid condensing water being vaporised again.
Phenomenon: Moisture on air outlet
Troubleshooting: If the unit operates at high humidity for a long time, moisture will be generated on the air outlet grill and then drip off.
Cleaning the Air Filter (every 3 months)
Do not to touch the fin of indoor unit during cleaning to avoid personal injury.
- Take down the air filter: Lift up the front panel. Pull the air filter downwards to take it off, as shown in Fig.(a, b).
- Clean the air filter: Use a vacuum cleaner to remove dust. If the filter are dirty, wash them with warm water and a mild detergent. Dry the filters in the shade.
- Reinstall the air filter: Reinstall the filters along the direction of arrowhead. Close the panel.
