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.
For proper usage of TDS meter, immerse the meter in the water/solution up to the maximum immersion level (2").
Lightly tap or stir the meter to remove any air bubbles. Wait 10-20 seconds for the reading to stabilize. In hot (or ice cold) water, wait 20-30 seconds for the meter to compensate for temperature. As the water temperature will adjust to room temperature, the reading will change to accommodate the proper compensation. To ensure greater accuracy, turn the meter off and on for each reading. Shake any water off the meter after each use. This is to remove the droplets of water that may adhere to the surface between the sensors and the housing around them. These drops may interfere with readings. Rinse in de-ionized water or other filtered water after use to ensure proper readings. Rinse in alcohol or acid after use in high-TDS beverages. The meter is not waterproof: Do not drop or submerge the unit in water. Do not store the unit in high temperature or direct sunlight.
- How to calibrate the meter
Measure the TDS level of the solution (follow usage instruction above).
If the meter does not read within 2% of 342 mg/L NaCl, adjust the reading by inserting a mini screwdriver into the trimmer pot (small hole on the rear of the meter). Gently turn the trimmer clockwise to increase the reading and counterclockwise to decrease the reading.
Once the meter reads within 2% of the solution, gently release pressure on the screwdriver and remove from the trimmer pot.
With the meter in the solution and the reading at the correct level, press the HOLD button. Let the reading hold for approximately 10 seconds to fully stabilize.
Remove the meter from the solution. Shake it to remove any water drops that may adhere to the probes and casing, creating air gaps.
Turn the meter off, wait a moment and turn the meter on again.
Insert the meter into the solution and verify the reading. If the reading is accurate, calibration is complete. If not, repeat the procedure.
Disclaimer:
TDS meter is given to check the TDS of your water at 25 7 temperature.
The 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.
While calibration, make sure the screwdriver fits evenly into the groove of the screw.
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.
HM Digital meters are factory-calibrated at 342 mg/L NaCl and designed to stay consistent. However, you may need to recalibrate your meter from time to time, or for certain applications. TDS meters are most accurate when calibrated as close as possible to the sample to be tested. For best results, calibrate at 25 7 (77 8). To ensure accuracy and consistency, recalibrate your meter using a commercial standard solution. This can be done prior to usage and should be done after prolonged usage. For drinking water, we recommend calibrating in a range of 90 mg/L to 700 mg/L.
