Replacing the Water Filter
Process of Purification
- Drinking water
Step 1 a
Out sediment filter with anti scalant module
Remove big particles, rust stains, mud etc. and reduce input water hardness to enhance filter life.
Step 2 b
Sedi + carbon filter
Remove unseen dregs and other contamination. Remove invisible fine particles, residual chlorine, VOC (Volatile Organic Compounds) etc.
Step 3 c
RO recovery filter*1, RO recovery plus filter*1
Remove dissolved impurities, heavy metals, bacteria, viruses, VOC etc. from water.
TDS reduction up to 90% ppm of source water.
Step 4 d
Mineral booster filter*1 (WW151/155/156/174/176)
Remove odour, add minerals in the purified water without mixing impure water.
Post carbon filter*1 (WW131/132/136/152)
Remove odor and improves taste of water.
Features and specifications may vary from model to model.
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.
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.
Filter name | Recommended purification amount (in litres)*1 |
|---|---|
Out sediment filter + Anti scalant module | 3000 6000 |
Sedi + carbon filter | 6000 |
RO recovery filter, RO recovery plus filter | 6000 |
Mineral booster filter | 6000 |
Post carbon filter | 6000 |
This is as per LGEIL standard.
Filter replacement and /or AMC request can only be placed via calling LG customer care (refer last page).
Warranty shall be void in case of use of counterfeit (duplicate) filters or replacement of filters from unauthorized sources.
Using counterfeit filters or procuring filters from unauthorized sources may negatively impact or degrade product performance and product life. It may not be safe drinking water and may also impact user's health.
LG shall not be responsible for any damage arising directly or indirectly out of any defect being noticed in the product due to usage of such counterfeit filters.
Out sediment filter may get choked in abnormal turbidity (sand and 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. Out sediment filter should be cleaned regularly to prevent choking in above condition for better performance. Life of filter may get affected by high turbidity and hardness of water.
If you wish to replace the filter, contact LG electronics customer care.
After replacing the filter, check if there is a leak from the product.
After installation, dispense 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 recovery filter, 2 45% (WW131, WW132, WW136, WW146, WW151, WW152, WW155, WW156) of supplied water (based on the tap water pressure of 8.8 kgf/cm2 (0.86 MPa) at water temperature of 25 7 and Input TDS up to 2000 mg/L) will be purified.
For RO recovery plus filter, 2 60% (WW174, WW176) of supplied water (based on the tap water pressure of 8.8 kgf/cm2 (0.86 MPa) at water temperature of 25 7 and Input TDS up to 2000 mg/L) will be purified.
No chemical preservatives used in membrane.
TDS Meter Details
TDS meter is given to check the TDS of your water filter.
- How to calibrate the meter
Prepare (359 ppm) 718 us/cm NaCl solution.
Immerse the probe in the solution for about two minutes.
Turn on the TDS meter switch, press and hold the HOLD key until the screen flashes, then release it, press the TEMP key and wait for the screen to finish flashing, and the calibration is completed.
Disclaimer:
TDS meter is given to check the TDS of your water at 25 7 temperature.
The TDS meter is not water proof so don’t dip the meter beyond the water level limit.
Do not store the meter at high temperatures or direct sunlight.
The meter should be recalibrated from time to time.
Water droplets or air gaps may cause the meter to display an incorrect reading.
TDS meter will show results within a tolerance of [10% when water TDS is greater than 150 mg/L. Tolerance to be checked as per IS 16240.
