Troubleshooting

The unit can not operate.

• Has the power been shut down?

 

• Is the power plug loosed?

 

• Is voltage too high or too low?

 

(tested by professional)

 

• Has the TIMER ON function been well

Breaking off

operated?

Cooling(Heating) efficiency is not good.

.

• Is temperature setting suitable?

 

• Does inlet or outlet vents obstructed?

 

• Is filter dirty?

 

• Are the windows and doors closed?

 

• Did fan speed set at low speed?

 

• Is there any heat sources in the room?

Remote control is not available.

• The unit is interfered by abnormal

 

interference or changing function too

 

frequently, wireless remote control can not

 

control occationally. Plug out power plug

 

and re-insert well could resume normal

 

operation.

 

• Is the control in the receiving area? Or is

 

there obstruction.

 

• Check if the voltage batteries in the control

 

is enough, if not, change batteries.

If water leakage in indoor unit.

• The air humidity is on the high side.

 

• Condensing water over flowed.

 

• The indoor unit drainage pipe connection

 

loosed.

If water leakage in outdoor unit.

• When the unit is running in COOL mode,

 

the connection of pipe and pipe joint will

 

be condensed due to the water cooled

 

down.

 

• When it is in "HEAT" or "Defrotsting", the

 

ice thawed and flowed out.

 

• When it is in HEAT, the water adhered on

 

heat exchanger dripped off.

Noise from indoor unit emitted.

• Fan or compressor relay switching

 

(On/OFF) sound.

 

• When it is defrosting or stop running, will

 

sound. That is due to the refrigerant flowing

 

direction is opposite.
