Ultra Big Capacity Drum
The LG Dryer has a large capacity.
Reduced drying time
Drying time is shortened by efficient air flow mechanism and
optimized heater.
Innovative Noise Reduction
Noise is reduced by optimized design of air flow system and vibration
reduction technology.
Ease of Use
Large LED display and electronic control.
Your dryer provides sensor drying and manual drying programs.
Sensor Dry Dryer electronically senses laundry moisture level and it automatically determines operation time
based on the dryness of the load and the selected program. At times,you can see sudden increase or
decrease of operation time. It happens because a sensor will detect laundry humidity with a certain period.
Sudden change of operation time is not a malfunction.
Manual Dry Manual Dry allows you to set operation time manually to complete drying. Or use Manual Dry if
clothes are still damp after sensor dry cycle is finished. Manual Dry is more effective for heavyweight and bulky
items such as king-size bed sheets and thick work clothes.

GROUNDING INSTRUCTION
This appliance must be grounded. In the event of malfunction or breakdown, grounding will reduce the risk of
electric shock by providing a path of least resistance for the electric current.
This appliance is equipped with a cord having an equipment grounding conductor and a grounding plug. The plug
must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes
and ordinances.
Additional Grounding Procedure
Some local codes may require a separate ground. In such cases, the required accessory ground wire, clamp and
screw must be purchased separately.
INSTALLATION INSTRUCTIONS
Level the dryer
1. Levelling the dryer is to prevent undesirable noise and vibration.
When placing your dryer in an solid and level area where water is not
dripping and freezing, flammable materials are not stored.
2. If the dryer is not properly level, adjust the front levelling legs up and
down as necessary.
Turn them clockwise to raise and counterclockwise to lower until the
dryer is not wobbling both front-to-back and side-to-side.
❊ Diagonal Check
When pushing down the edges of the washing machine, the machine should not
move up and down at all. (Please, check both of two directions)
If machine rocks when pushing the machine top plate diagonally, adjust the feet
again.
