Important Safety Instructions
To reduce the risk of explosion, re, death, electric shock, injury or
scalding to persons when using this product, follow basic precautions,
including the following:
Installation
•This appliance should only be transported by two or more people holding the
appliance securely.
•Ensure that the outlet socket is properly earthed, and that the earth pin on the
supply cord is not damaged or removed from the plug. For more details on
earthing, inquire with your distributor, supplier or dealer.
•This appliance is equipped with a power cord having an equipment-earthing
conductor and an earthing power plug. The power plug must be plugged into an
appropriate outlet socket that is installed and grounded in accordance with all local
codes and ordinances.
•If the power cord is damaged or the holes of the outlet socket are loose, do not
use the power cord and contact an authorized service centre.

To reduce the risk of minor injury to persons, malfunction, or damage to
the product or property when using this product, follow basic precautions,
including the following:
Installation
•Do not tilt the appliance to pull or push it when transporting.
•Connect the water pipe of the appliance to potable water only. Water other than
potable water can increase the risk of exposure to disease. Other types of water
can reduce the appliance life or cause malfunctions.
•Hot water may splatter, so install the drain hose carefully to the drain.
•Make sure not to get a body part such as a hand or foot stuck while moving the
appliance.
Operation
•Prevent animals from nibbling on the power cable or water hoses.
•Supervise a child or a person with poor cognitive skills to ensure they use the
appliance safely.
•Do not damage the pipes of the refrigerant circuit.
•Replace the lter with a LG standard lter periodically according to the replacement
period. Older lters can multiply bacteria or change the taste of the water. The lter
replacement period varies according to the usage, place of usage, season, and
water quality.
•When using hot water, use a container with a handle.(Only applicable to a model
with hot water function)
•Take care against the possibility of damaging the pipe (inlet, outlet) in order to
prevent water leakage.
•Do not allow pets, or any persons to hang from or climb on the appliance.
•Be particularly cautious of children operating the appliance.

and sides of the appliance and the wall for proper
ventilation. Not doing so can cause malfunctions.
•When connecting the water hose, do not connect it to
the hot water tap. Doing so may cause malfunctions.
•Check the pipe and hose connection for leaks. Water
can leak and cause electric shock or injury.
•When transporting the appliance, do not tilt the
appliance over 30 degrees. Doing so can cause
malfunctions.
•Install the appliance in an indoor place with a
surrounding temperature of over 5 °C and less than
35 °C. Not doing so can cause malfunctions.
•Avoid installing the ltered water dispenser in a place
with an uneven ground, a large amount of moisture,
direct sunlight, dust, and direct water splashing.
•Connect the appliance to a drinking water tap with a
water pressure of 147-780 kPa (1.5-7.9 kgf/cm
2
). Not
doing so may cause malfunctions.
•Water should fall through the hot water tank pipe, and
this pipe should be left open.

11
ENGLISH
Notes for Operation
•Open the water supply valve. The ltered water
dispenser operates normally when water is supplied
properly at a consistent pressure that is within the
operating requirement.
•When the hot water and cold water temperature icons
are turned off, check if the power supply has been lost
due to power failure or other reasons.
•It is very important to replace the lter periodically in
order to drink clean water. When using an expired
lter, the performance of the ltered water dispenser
can deteriorate. Always abide by the lter replacement
period.
•If the appliance has not been used for a long period
of time, discharge cold water, Ambient water, and hot
water for 10 minutes each before using, and then use.
Old water can multiply bacteria or change the water
taste.
•Do not use ltered water for replacing water in a
humidier or shbowl. Leaving ltered water as it is for
a long period of time can cause the water bacteria to
multiply.
•Use the appliance only after closing the appliance
cover completely. Otherwise, insects or other foreign
substances may get in.
•When heating or freezing water, white sediment may
appear due to minerals in water. These minerals are
harmless to humans.
•Water may remain inside the appliance due to the
inspection process carried out while manufacturing the
appliance. This is not a sign of the appliance having
been used previously and is safe to use.
•Do not use a mechanical device other than any, and
if recommended for improving the performance of
the ltered water dispenser. Doing so may cause
malfunctions.
•When using hot water, place a container such as a
cup close to the water outlet. Not doing so can cause
hot water to splash, resulting in burn injury.
Suggestion for Energy Saving
•If the appliance will not be used for a long period of
time, unplug the power plug and drain the water inside
the ltered water dispenser completely.
•In case the hot water or cold water function will not be
used, turn the hot water or cold water function off.

dispenser for a long period of
time without using it?
•The taste of water may change as it ages
due to bacterial multiplication. Use the
ltered water dispenser after discharging
cold water, hot water and Ambient water
for 10 minutes respectively.
Has it been a long time since you
installed or replaced the lter?
•If an expired lter is used, the
ltration performance may decline. It
is recommended to replace the lter
according to the lter replacement period.
The dispensing volume
has reduced suddenly.
Is it time to replace the lter?
•Make a request for a lter replacement.
Is the water supply valve or tap
closed?
•Open the water supply valve.
Water does not
dispense.
Did you miss the lter
replacement period?
•Make a request for a lter replacement.
Is the water supply valve or tap
closed?
•Open the water supply valve.
Is the power plug unplugged from
the outlet?
•Plug the power plug in the outlet correctly.
Is the Lock lamp on?

Symptoms Reason Solution
Cold water, hot water or
Ambient water does not
dispense.
Did you turn off the relevant
function?
•Turn on the relevant function.
Did you discharge a large amount
of cold water?
•If you discharge a continuous amount of
cold water, the temperature of the cold
water inside the cold water tank drops
and tepid water will dispense. Wait a while
until the cold water becomes colder and
then try again. (Only applicable to models
with a cold water tank)
Did you discharge a lot of hot
water?
•If you discharge a continuous amount
of hot water, the temperature of the hot
water inside the hot water tank drops and
tepid water will dispense. Wait a while
until the hot water becomes hotter and
then try again. (Only applicable to models
with a hot water tank)
Did you discharge a lot of
Ambient water?
•If you have discharged a lot of ltered
water (including Ambient water) so that
there is little ltered water in the storage
tank, ltered water may not dispense.
Wait a while until water is lled inside the
storage tank and then try again. (Only
applicable to models with a storage tank)

19
ENGLISH
Symptoms Reason Solution
The appliance is
noisy and generates
abnormal sounds.
Is the appliance installed on a
weak oor or not installed on a
stable surface?
•Install the appliance in a place with a at
and even surface.

Have 6 hours passed since the
installation to water and power?
•Use the appliance after 6 hours of having
installed it to water and power.
Fine particles occur in
the ltered water.
Has the unit just been installed or
the lter just replaced?
•Water bubbles may form in the ltering
process when the unit is newly installed
or the lter has just been replaced and
cause the water to appear cloudy. it is
normal and the water is safe to drink.
•If ne particles still exist after you have
ushed each water dispensing outlet for
10 minutes, then turn off the water supply
and disconnect from the mains power and
contact your distributor, supplier or dealer.
