3. Low noise of the air conditioner

You may hear a low hissing sound when the compressor is running or has just stopped running

This sound is the sound of the refrigerant flowing or coming to a stop.

You can also hear a low “ Squeak ” sound when the compressor is running or has just stopped

running.  This is cause by heat expansion and cold contracttion of the plastic parts in the unit

A noise may be heard due to louver restoring to its orioiginal position when power is first turned on.

Dust is blown out from the indoor unit

This is a normal condition when the air conditioner has not been used for a long time or during

first use of the unit.

The peculiar smell come from the indoor unit

furniture, or smoke.

The air conditioner turns to FAN only mode from COOL or HEAT mode (For cooling and heating
models only).

6.

When indoor temperature reaches the temperature setting on air conditioner,  the compressor

will stop automaticall. And the air conditioner turn to FAN only mode. The compressor will

start again when the indoor temperature rises on COOL mode or falls on HEAT mode (For cooling

and heating models only).

Dripping water may generate on the surface of the indoor unit when cooling in a high relatively

hamidity (relative humidity higher than 80% ).  Adjust the horizontal louver to the maximum air

outlet position and select HIGH fan speed.

Heating mode ( For cooling and heating models only )
The air conditioner draws in heat from the outdoor unit
and release it via the indoor unit during heating operation.
When the outdoor temperature falls, heat drawn in by the
air conditioner decreases accordingly.  At the same time,
heat Ioading of the air conditioner increases due to large
difference between indoor and outdoor temperature.
If a comfortable temperature can not be achieved by the
air conditioner, we suggest you use a supplementary heating device.

9.  The power cable should be H05VV-F.  The connecting cable should be H07RF.
