Maintaining the filter Purification process

Step 1: Sedi+Pre carbon filter

- This filters out unseen residue, residual chlorine and volatile organic compounds.

Step 2 : RO membrane filter

- This filters out heavy metals, ionic substances and microorganisms. Some of the water that passes through the membrane filter is drained through the drain hose.

Step 3 : Post-carbon block filter

- This filters out odour-causing substances in water.

NOTE

- Do not use water drained from the appliance for drinking or cooking.

- Use the water instead for cleaning the bathroom and house, doing the laundry 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 block filter has come out, and it is harmless to the human body.

Filter replacement period

The filter replacement period refers to the period that the purification performance of the filter is maintained. This replacement period is set based on a daily usage of 10 liters. However, 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
1 filter 6000 ℓ
2 filter 6000 ℓ
3 filter 6000 ℓ

① Sediment+pre carbon filter
② RO membrane filter
3 Post-carbon block filter

NOTE

• After replacing the filter, check if there is a leak from the appliance.
• After two hours, drain the cold, hot and ambient water for about 10 minutes before using it.
• 20-35% of supplied water (based on the tap water pressure of 3.5 kgf/cm ^3 at the water temperature of 25 °C) will be purified and the remainder will be drained.
