Maintaining the filter

Process of Purification

Drinking Water

Step 1:

Out sediment filter with anti scalant module

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

Step 2:

Sedi + 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 upto 90% ppm of Source Water.

Step 4:

(For WW130 model) Post-carbon filter

• Removes odour & improves taste of water.

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

• Removes odour, add minerals in the purified water without mixing impure water.

Diagrams illustrate the steps of filter replacement.

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.

Diagrams illustrate the steps for cleaning water for fruits & veggies.

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 tank completely.

* For selected models only.

** As per LGEIL standard.

# Anti-scalant module is applicable with out 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.

NOTE

• If you wish to replace the filter, contact LG Electronics service centre.
• After replacing the filter, check if there is a leak from the product.
• After installation, discharge water for the first time when water tank is full. Same process is to be followed after every filter change or digital sterilization. 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 kgf/cm² 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 of 1.5kgf/cm², 750ppm TDS at water temp. of 25°C) will be purified and remainder will be drained.
• CAUTION: Outsediment filter may get choked in abnormal turbidity (Sand & mud) condition, it is suggested to switch ON water purifier after 1-2 hour of overhead tank filling so that sand/mud will get settled. Outsediment filter should be cleaned regularly to prevent choking in above condition for better performance.
