Features & Benefit

Environment Friendly Refrigerant :

- LG Air conditioners uses environment friendly refrigerant. Which don't do any harm to the environment.

Jet Cool:

- In this mode very quick and fast cooling is done. The unit will continue to supply high velocity air for 30 min- utes, untill the room temperature reaches 18°C. After 30 minutes, unit will supply air at the set fan speed whether indoor temperature has reached 18°C or not.

Self Diagnosis Function:

-This function provides diagnosis of the unit. Blinking of the operation LED of the indoor unit means there is some error.

Cooling, Heating & Fan Operation:

-LG multi air conditioners can provide cooling, heating & fan operation. In the cooling mode, it cools the air with an operation range of 18~30°C. In the heating mode, it heats the air with an operation range of 16~30°C. In the fan operation mode, only indoor fan will run at the selected speed, outdoor fan and compressor will be off.

LCD Wireless Remocon:

- It provides ease of control.

Auto Restart Operation :

-When there is electricity failure the unit sharts off. After resumption of the power, unit will start in the same mode as prior to the power failure. Memorized condition are on / off condition, operating mode (cooling/heat- ing), set temperature and fan speed. The unit will memorize the above conditions and start with same memo- rized condition.

Hot Start Function :

-During starting of the unit in the heating mode it prevents cold air blow from the unit.It starts the indoor fan only after indoor unit pipe temperature reaches a preset value(28°C). When indoor unit pipe temperature has reached 28°C, then for initial 1 minute the indoor fan runs at low speed and after that at the set fan speed.

Defrost / Deicing :

-In the heating mode, it prevents the ice formation on the outdoor unit. Sensing the outdoor piping temperature, If it is lower than some preset value then the outdoor fan stops and compressor continues to run till a particular temperature is reached. Thereby preventing the frost on the outdoor coil. After reaching a particular high tem- perature outdoor fan again starts.

Time Delay Safety function:

-It delays restarting of the compressor by three minutes thereby preventing damage to the compressor .
