Installing water purifier

1. connects the product hoses as shown below.
   • Connect the white (water supply) hose to tap water.
   • Install the blue (drain) hose on the sink.

2. Connect the power cord to an appropriate socket.

3. Open the water supply valve.

4. after installation, discharge water for the first time when the water tank is full. The same process is to be followed after every filter change or digital sterilization. The approximate time taken to fill the tank to the fullest is 1 hour, depending on water pressure, temperature, etc.

CAUTION

Handle all packaging materials (such as plastic bags and thermocouples) to keep away from children. The packaging materials can cause suffocation.

Important Note: All models can only be installed with a water supply from the overhead storage tank. No other
water supply should be used for install

OPERATION

Notes for Operation

• Open the water supply valve. The water purifier operates normally only when water is supplied properly.
• It is very important to replace the filter periodically in order to drink clean water. When using an expired filter, the performance of a water filtration system can deteriorate. Always abide by the filter replacement period.
• If the product has not been used for 2 or more days, discharge the stored water from the water purifier tank.
• Do not use purified water for replacing water in the humidifier or fishbowl.
• Use the product only after closing the product cover completely. Otherwise, insects or other foreign substances may get in.

Note

• The reverse osmosis contains a replaceable treatment component critical for the effective reduction of total dissolved solids and that product water shall be tested periodically (during service engineer visit) to verify that the system is performing properly.
• Do not use water that is microbiologically unsafe or of unknown quality, without adequate disinfection before or after the system.

Suggestion for energy saving

• If the product will not be used for 2 or more days, unplug the power plug and drain the water inside of water filtration system completely.

• For selected models only

Using Control Panel

Water level indicator
The water level of the storage tank is displayed in 3 levels.

• The icon is divided into 3 levels according to the water level, and as more indication Lights turn on, The water level becomes higher. However, The water level cannot be adjusted discretionally.

**UV Sterilizing indicator***

Purified water is sterilized by the UV LED. The blue color indicates that UV sterilization is ON & white color indicates that UV sterilization is OFF. For WW151NP, the UV indicator will glow. (When tank cover is open, UV LED will be automatically turned OFF for your safety.)

NOTE
The UV LED operates in any of the following 2 cases.

• It operates for 75 minutes in every 6 hours.
• It operates for 75 minutes after approximately 2 seconds when power is turned on following a power failure.

*Filter Change indicator^**

When the color of the indicator changes from blue to amber, this indicates that it is time for preventive maintenance service. Please call LG customer care for service.
**Power indicator***

The Power LED glows to indicate the ON condition of the Water Purifier.
**Tank Full Indicator***

When the water storage tank gets filled up completely then the Tank full indicator will turn ON.

Operation
Using purified water
When you press the touch lever, purified water will come out.

NOTE
If you wish to discharge continuously, lift the touch lever upward.

Caution: Open this lever to 90° only.#
Opening more than 90° may cause it to malfunction/damage.
**Using the fruit & vegetable cleaning water***
Open the valve. You can rinse fruits and vegetables, wash dishes.
The function discharges water while the valve is opened.

NOTE
Do not use this water for drinking and cooking.

Important note for all models:
All models of water purifier come with a unique flow sensor (To protect the product from running without water supply) which turns on only if there is running water supply to water purifier. If no/lower water supply than specified limit is available, then water purifier will stop for 15 minutes and later, runs again for few seconds to check the water supply.
If the water supply is detected, then the water purifier will work normally otherwise it will repeat to check cycle again. If the water supply is available & you want to start water purifier immediately, just turn off the power supply and wait until the Display gets turned off, and turn on the power again.
^ Applicable for Out Sediment filter

• For selected models only

Maintaining the filter

Process of Purification
Drinking-Water
Step 1:
Out sediment filter with antiscalant module

• Removes big particles, rust stains, mud, etc., and reduces input water hardness to enhance filter life.

Step 2:
Side + Carbon filter

• Removes unseen dregs and other contamination & removes invisible fine particles, residual chlorine, VOC (Volatile Organic Compounds), etc.

Step 3:
RO membrane filter / RO recovery plus

• Removes dissolved impurities and removes heavy metals, bacteria, viruses, VOC, etc. from water.
• TDS Reduction up to 90% ppm of Source Water.

Step 4:
(For WW130 model)
Post-carbon filter

• Removes odor & improves the taste of water.

(For WW140/151/182/172 models)
Mineral booster filter

• Removes odor, adds minerals in the purified water without mixing impure water.

**Cleaning water for fruits & veggies***
(Only with WW182EP)
Step 1:

• Out sediment Filter with antiscalant module. Removes big particles, rust stains, mud, etc. and reduces input water hardness to enhance filter life

Step 2:
UF membrane filter*

• Removes only bacteria and fine particle substance.

NOTE

• Do not use water drained from the product for drinking or cooking.

• Use the water instead for cleaning the bathroom and house, gardening or for other various purposes.

• Activated carbon inside the filter may sometimes flow in the storage tank. If so, a fine powder of activated carbon used in the post-carbon filter has come out, and it is harmless to the human body. If found, drain out the water from the tank completely.

• For selected models only.
  ** As per LGEIL standard.

  Anti-scalant module is applicable without sediment filter only for

  WW130/140/151/182/172 models.

Filter replacement period
The filter replacement period refers to the period that the purification performance of the filter is maintained. And, the replacement period is lesser in the case of a place with poor water quality or a large purification amount.

6000 #
Sedi + Carbon filter| 6000
RO Membrane filter RO Recovery Plus| 6000
Post-carbon filter| 6000
Mineral booster filter| 6000
OF membrane filter| 6000

NOTE

• If you wish to replace the filter, contact the LG Electronics service center.
• After replacing the filter, check if there is a leak from the product.
• After installation, discharge water for the first time when the water tank is full. The same process is to be followed after every filter change or digital sterilization. The approximate time taken to fill the tank to the fullest is 1 hour, depending on water pressure, temperature, etc.
•  For RO Membrane Filter, around 25% of supplied water (based on the tap water pressure of 3.5 2 kg/cm at water temp. of 25°C ) will be purified. While for RO Recovery Plus, around 50% of supplied water (based on the tap water pressure 2 of 1.5kgf/cm, 750ppm TDS at water temp. of 25°C) will be purified and the remainder will be
  drained.

CAUTION: Outsediment filter may get choked in abnormal turbidity (Sand & mud) condition, it is suggested to switch ON the water purifier after 1-2 hours of overhead tank filling so that sand/mud will get settled. Outsediment filter should be cleaned regularly to prevent choking in the above condition for better performance.
