be performed by two or more qualified service
personnel.
• The weight of the appliance and the height of the
installation makes the installation procedure too
risky for one person.
• Incorrect installation can cause serious
accidents.
• Do not operate if the appliance is not properly
stacked.
1 Place the appliance on the top of an LG front
load washing machine.
2 Remove the 2 screws from the bottom of the
rear cover on each side.
3 Align the LG stacking kit holes and the rear
cover holes in a line.
• In case of the top plate size is 600 mm

4 Fasten the 2 screws that were removed earlier
from the appliance to the stacking kit.
5 Use the 4 screws in the accessory box (16 mm)
to assemble the washing machine rear cover
and stacking kit.
6 The procedure for the opposite side will be the
same.
Installing the Optional Drain
Hose
Normally, condensed water is pumped up to the
water container where water is collected until
manually emptied. Water can also be drained out
directly to a mains drain, especially when the
appliance is stacked on top of a washing machine.
With the connecting elbow or T piece of the mains
drain hose, simply change the water path and re-
route to the drainage facility as below:
1 Separate the anti-backflow lid a and the water
container hose
b from the connecting elbow
or T piece.
2 Attach the anti-backflow lid a to the head of
the connecting elbow or T piece and then
connect the optional drain hose
c to the
opposite side of the connecting elbow or T
piece.
CAUTION

OPERATION
Operation Overview
Using the Appliance
Before the first cycle, set the appliance to dry for 5
minutes to warm up the drum. Open the door
between loads the first few times you use the
appliance to allow any odours from the interior of
the appliance to disperse.
Children must be supervised so that they do not
climb inside the drum.
1 Ensure the lint filter and water container are
clean.
• Open the door and ensure the lint filter is
clean. When the filter is full with lint, drying
times will be longer than usual.
• Pull out the water container and empty the
condensed water. When the water container
is full, the appliance may stop during the
cycle.
NOTE
• In some instance, LED window may display E
icon to inform you that the water container is
full. If this occurs, empty the water container.
2 Place the clothes into the drum after sorting
and close the door.
• Push the clothes deep into the drum so that
the clothes keeps away from the door seal.
When the clothes get stuck between the
door and seal, they may get damaged while
drying.
• The clothes should be sorted by fabric types
and dryness level.
• All strings and attached belts of clothes
should be well tied and fixed before being
put into the drum.
3 Press the Power button to turn the appliance
on.
• Depending on the models, the
Power button
may light up to indicate that the appliance is
ready for dry.
4 Choose a drying programme by turning the
programme selector knob.
• If you press the
Start/Pause button without
choosing a programme, the appliance will
proceed with the
Cotton programme.
Please refer to the programme table for the
detailed information.
5 Press the Start/Pause button to start the
drying programme.
NOTE
• The appliance washes lint, which builds up onto
the surface of the condenser, automatically
using water that is condensed from the clothes
during operation.

16
OPERATION
NOTE
• The frequency of cleaning condenser may vary
depending on the size and the initial moisture
amount of the clothes.
6 After the drying programme has finished, open
the door and unload the clothes.
CAUTION
• Be careful! The drum inside may still be hot.
7 Press the Power button to turn the appliance
off.
8 Clean the lint filter and empty the water
container.
9 To help reduce odours from forming, the
dryer’s door can be left open or slightly ajar for
a short period of time if possible to help
ventilate the drum after use.
WARNING
• For safety reasons, do not allow children or
animals to enter the appliance. It may cause
damage or injury.
NOTE
• The final part of a tumble dry cycle occurs
without heat (cool down cycle) to ensure that the
clothes are left at a temperature that ensures
the clothes will not be damaged.
• A high atmospheric temperature and a small
room may both increase drying time as well as
energy consumption.
Preparing the Clothes
NOTE
• Do not overload the appliance for the best
drying performance and most efficient energy
usage.
Checking the clothes before
loading
CAUTION
• Check that the clothes are not stuck between
appliance and door, otherwise the clothes may
get damaged while drying.
• Observe the maximum load capacity on the
programme table for the relevant drying
programme to get optimum drying results.
Overloading gives a poor drying result and
causes unnecessary creasing.
• Do not load soaking wet clothes into the
appliance. It will cause an increasing of drying
time and energy consumption. Make sure that
the clothes are spun thoroughly before loading.
• A mixed fabric load can cause the drying time to
be extended and the time remaining in the
display to pause during active drying. The
remaining time will then continue when it is the
actual time that remains.
• Make sure to empty all pockets. Items such as
nails, hair clips, matches, pens, coins and keys
can damage both your appliance and clothes.
• Remove loose belts and close zippers, hooks and
strings to make sure that these items do not
snag other clothes.
Sorting the Clothes
Clothes have their own fabric care labels, so drying
according to the fabric care label is recommended.
Sort the clothes into size and type of fabric and
then prepare the clothes according to the symbols
on the fabric care labels.
