Process of water purification

LG WQD74RJ5P - Process of water purification - 1

Notice

The filter is vital to the water purifier. If an authentic filter is not used, or if an old filter is used even though it is authentic, this can cause performance deterioration.

Process of purification

Step 1: Sediment filter

This protects the part (or place) where water contacts by filtering unseen dregs and contaminated substances.

LG WQD74RJ5P - Step 1: Sediment filter - 1

Step 2: Pre carbon filter

Remaining chlorine and volatile organic compounds are removed at this pre-carbon filter.

LG WQD74RJ5P - Step 2: Pre carbon filter - 1

Step 3: Membrane Filter (R/O)

Heavy metallic substances, ionized substances, and microorganisms are removed through this membrane filter. At this step, drained water comes out along the drain hose.

LG WQD74RJ5P - Step 3: Membrane Filter (R/O) - 1

Step 4: Post carbon filter

Smell left in water is filtered at this step, and the taste of water is improved.

Drained Water

  • You can use drained water for daily activities like dish washing, laundry, cleaning, etc.
  • Please do not use this water for drinking and cooking.

Open the Tap Water Valve

The product operates when tap water is supplied.

When the display's indicator light is turned off

When the display's indicator light is turned off, check if the power supply is stopped by a power outage or other causes.

When the product is not used for a long time (e.g., 2-3 days)

If water has been kept in the tank or hasn't been used for a long time, drain the water completely.

Do one more draining with newly purified water, then use.

After installation

Throw away the water stored to the full level in the inside tank more than once before use.

It takes around 3 hours for water to reach the full level, but the time varies depending on water pressure.

Periodical change of filter

Filter changing is very important for clean water.

Do not miss the time for filter replacement, since an old filter can't function well.

How to drain hot water

Take off the cap of the hot water drainer on the side of the product, and connect it with a drain hose.

When and how to replace a filter

When to replace the filter

Filter

The filter is the most important part of a water purifier. If it is not a genuine filter, or even if it is a genuine filter but used for too long, it can affect the performance of the filter so that it may not purify water properly.

Replace with a genuine filter according to the replacement period.

Genuine filter

Filter replacement period

If the filter is not replaced regularly, it can degrade the water quality of the purifier. The expected replacement period of the filter can change depending on the water quality and usage.

* Filter replacement period is based on using 10 liters daily for household use.

Filter replacement

Filter Name Expected replacement period
Sediment Filter 3 Months
Pre Carbon Filter 6 Months
Membrane Filter (R/O) 24 Months
Post Carbon Filter 12 Months

What is a valid filter capacity?

The valid filter capacity written on the product specification is to determine the performance of the purifying system and means the filter capacity calculated by the elimination rate of chloroform, etc.

About Filter Replacement Period

The filter replacement period listed above is not a guarantee of the filter's quality, but rather the expected period during which the filter will perform effectively. (Based on tap water supply)

How to Replace the Filter

1. Close the tap water valve, then completely drain the water from the tank.

Close / Open

2. Unscrew the 2 screws on the right side of the product, then detach the filter cover.

Diagram showing a hand holding a tool next to a cabinet with a downward arrow indicating motion (no text or symbols present)

CAUTION

- The filter must be replaced after being washed.

- The pre-carbon, membrane, and post-carbon filters need to be washed with sediment-filtered tap water for 10 minutes before assembly.

- If replacement is done without washing the filter:

  • Black-colored water may come out due to activated-carbon powder or initial activated-carbon.
  • Since it is impossible to check if the filter is blocked, this may cause a breakdown.

LG WQD74RJ5P - CAUTION - 1

Notice

  • Activated carbon from the filter may flow into the tank.
  • This fine powder of activated carbon, which improves the taste of water, comes out from the post-carbon filter and is not harmful to human health.
  • Drain the water and wipe with a dry cloth.

3 Wash the filter that needs to be replaced, and then change the filter.

Detach fittings that are connected to the filter using adequate tools. Separate the old filters by pulling them from the bracket.

Tubing, Fitting, Filter Bracket

CAUTION

Four identical gas washing bottles with different cap types and inlet/outlet labels (no visible text or symbols on the bottles themselves)

After replacing the SVC filter, be sure to perform the assembly as shown in the photograph.

After filter replacement, check the fitting and tubing for water leakage. The initial purified water needs to be drained at least once.

  • The filter needs to be replaced after being washed.

- Sediment, pre-carbon, membrane, and post-carbon filters need to be washed with sediment-filtered tap water for 10 minutes. Then assemble.

• In case replacement is done without washing the filter

  • Black-colored water may come out due to activated-carbon powder or initial activated-carbon.
  • Since it's impossible to check if the filter is blocked, this may cause a breakdown.
  • Consult with an LG Healthcare manager for details to maximize the performance of the product.

Notice

  • To drink clean water, changing the filter is very important. Old filters cause a decline in efficiency, so don't miss the filter changing time.
  • Filter replacement time varies depending on each filter's characteristics. (Refer to the Filter Replacement Period on page 25.)
