Process of water purification
Process of Purification
Notice
The filter is a vital part of the water purifier. If authentic filter is not used, or old filter
is used even if it is an authentic one, such can cause performance deterioration.
Step 1: Out Sediment filter
Step 2: Sediment filter
Step 3: Pre-carbon filter
Step 4: RO membrane filter
Step 5: Post-carbon filter
Drinking water
Remove large visible impurities as
well as finer suspended particles such
as dirt and sand from the water.
This protects the part (or place) with
which water comes in contact by
filtering unseen dust and contaminated
substances.
The remaining chlorine and volatile
organic compound are removed at
this pre-carbon filter.
Heavy metallic substances, ionized
substances, and microorganism are
removed through this membrane filter.
At this step, 1)drained water comes
out through the drain hose.
The remaining smell in the water is
filtered at this step, and the taste of
water is improved.
Step 1: Out Sediment filter
Step 2: UF membrane filter
Cleaning water for fruits & veggies
(※ for WAW73JW2RP, WAW53JW2RP only)
Remove large visible impurities as
well as finer suspended particles such
as dirt and sand from the water.
The 0.05~0.2 micron-sized hollow fiber
membrane filters microorganisms and
other impurities and lets mineral contents
pass through.
(Filters can be added
depending on the installation environment.)

Check before using
※
Be sure to check before use!
Open the Tap water Valve
When the Display's indicator light is turned off
When the product is not used for a Long time (ex. 2~3 days)
After the installation
Periodical change of filter
The product operates when Tap water is supplied.
When the Display's indicator light is turned off, check if power supply is stopped due to
blackout or other causes.
If water has been kept in the tank or has not been used for a long time, then drain the
water completely.
Drain the newly purified water one more time and use the purified water generated
after this process.
Throw away the water when the inside tank is full more than once before use.
It takes around 1 hour for the water to reach full level, but the time differs by water,
pressure, temperature, and filter activating rate.
Filter replacement is very important for clean water.
Take note of the time for filter replacement, since the old filter will not function well.
Notice
If the product is not used for a long time, unplug the power cord and close the
Tap water valve.

Notice
Notice
The water level is indicated in 3 levels, with level 3 as the highest.
※The water level indicator is fixed, so it cannot be changed.
UV sterilizing is divided into 3 types: Purification, Circulation, and Power Failure
Compensation; the operating time differs for each mode.
• Purification Sterilizing: This function works whenever the tank is filled with
water to be purified. The processing time may vary depending on the amount
of water.
• Circulation Sterilizing: This function is automatically activated when the tank
is full of water stored for a certain period of time. An internal circulation pump
mixes water to kill the germs contained in the water.
• Power Failure Compensation Sterilizing: This function is to sterilize the
water in the tank in case of blackout or when power has not been supplied for
a long time. This process takes the longest time.
