• Condensation effect due to cooling process. Water flowing sound during operation. • Refrigerant flow inside the unit. The room has a peculiar odour. • This may be due to damp smell emitted by the wall, carpet, furniture orclothing. Indoor fan stops occasionally during automaticfan speed setting. • This helps to remove the surrounding odours. Operation is delayed a few minutes after restart. • The delay is a protection to the unit’s compressor. Outdoor unit emits water/steam. • Condensation or evaporation occurs on pipes. Timer indicator is always on. • The timer setting repeats daily once set. Indoor fan stops occasionally during heatingoperation. • To avoid unintended cooling effect. Cracking sound can be heard duringoperation. • Changes of temperature cause the expansion/contraction of the unit. Unit switch to FAN operation and air becomehumid. • This happens when the room temperature reaches the set temperature, operation switches to FAN mode and the humidity increase. Outdoor unit emits noise during heatingoperation. • This is due to changes inflow of refrigerant gas when operation stopsand starts. Operation does not stop immediately afterpressed the OFF/ON button. • Discharging heat is in process. Operation will stops automatically afterapproximately 60 seconds. Operation stops occasionally. (“DEFROST” appears on the remote control display) • The unit is in defrosting mode, and the melted frost is drained from theoutdoor unit. Airflow does not start immediately afteroperation is started. (“PRE HEAT” appears onthe remote control display) • The unit is warming up to provide warm air. Operation starts after power resumes. • Auto restart is in function and operates under previous setting. During dry mode, cold air blow out. • The unit is running cooling operation with low fan speed to dehumidifythe room. Fan speed change occasionally during heatingmode. • The room temperature has reached the remote control setting. When theroom temperature drops again, the fan speed will resume to the remotecontrol settings. Outdoor unit emits steam during heatingmode. • This is due to defrost operation happens at the heat exchanger. The following symptoms do not indicate malfunction.The following symptoms do not indicate malfunction.
