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
