Phenomenon | Troubleshooting |
|
|
The unit can not be started up: | ● Is the power connected? |
| ● 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? |
Cooling/Heating effect is poor: | ● Is temperature setting appropriate? |
| ● Is the inlet or outlet blocked? |
| ● Is the filter dirty? |
| ● Is low fan speed set? |
| ● Are there heat sources in the room? |
Remote controller is not working: | ● Check the conditions of the batteries and replace them if |
| necessary. |
| ● Check if there is magnetic or electrical interference near |
| the unit that may affect 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 if the remote controller is damaged. |
Water leakage of indoor unit: | ● The humidity is high. |
| ● Condensing water overflows. |
| ● Drain hose is loose or blocked. |
Water leakage of outdoor unit: | ● During cooling operation, water condensate is |
| generated around the pipes and connection joints. |
| ● During defrosting operation, the thaw water flows out. |
| This is normal |
Noise from indoor unit: | ● The noise emitted when the fan or compressor relay is |
| switched on or off. |
| ● Dirty filters will cause the fan to vary in speed. At this |
| time please clean filters. |
The unit does not operate: | ● The unit does not operate if it is turned on immediately |
| after it is turned off. |
“Water flowing” noise: | ● The swishing noise like water flowing is the refrigerant |
| flowing inside the unit. |
Mist is emitted in COOL mode: | ● 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. |
Immediately stop all operations, disconnect from the power supply, and report to an
authorised air conditioner contractor in the following situation:
● There is harsh sound during operation
● Strong odours are emitted during operation ● Water is leaking in the room
● Circuit breaker continuously trips off
● Water has dripped into or been splashed on to the unit ● Power leads or connections have bee damaged
