Precaution
1-3 Precautions on use
1. Right after the installation, fill up the water tank and drain the water. Repeat it at least twice before
use.
2. If water has been stored in the water tank for a long time without using the unit, completely drain the
water and clean the tank. In the case the tank cannot be cleaned, drain the water once again before
use.
3. In order to have clean potable water, replace filters regularly.
- If filters are overused beyond their service life, the quality of the purified water may deteriorate.
4. Keep the surrounding areas neat and clean the inside of the water tanks once every two months.
5. Do not place a heavy object or exert excessive pressure on the top of the product.
6. Do not exert excessive shock on the product.
7. After moving the product or replacing the post-carbon block filter, the black powder can be remained
in the inner bottom of the water tank.
- As the powder of active carbon used in the post-carbon block filter was flowed down to make the
taste of the purified water better, it is safe for humans to use.
8. The non-return of the cup-touch lever can be occurred due to the shock and the carelessness
during the transport to extract continuously. (Use after operating the sliding lever up and
down 1 ~2 times.)

3-2-1 Precautions on installation
 The water tank capacity of this water purification system is designed for home use.
It is prohibited to install the system for medium/large business or public use.
(If the water purification system is used beyond its capacity, water shortage and/or shortened
filter life may occur as a result.)
 Install the product at least 10cm away from the wall and on a firm and level floor.
 Installation water pressure
- The feed water supply pressure should be at least 20 psi (0.14 MPa) for the purification system to
work properly, providing enough purified water.
 Installation distance from tap water supply
- Feed water pressure 20 psi (0.14 MPa) or higher: Install the system in a place within a range of
3M in height and 25M in distance.
 Do not install the system in a place where it is subjected to direct sunlight, freezing
temperature, and/or excessive moisture.
 In the case the system is newly installed or relocated, read the User’s Manual once again
before installation.
 This product is for AC 220V/50Hz. Make sure to check the rated voltage before connect the
power cord to the electrical outlet. (P-07QR only )
 Make sure to connect the feed water inlet hose to the cold water piping.
- In the case the feed water inlet hose is connected to warm water piping with the water temperature
of 40°C or higher, filters may be damaged.
 Right after the installation, fill up the water tank and drain the water.
Repeat it at least twice before use.
