Installation precautions
Before using the water purifier, please read this Manual carefully and keep it for future reference.
1. To avoid damage to your body, use municipal tap water;
2. During initial use, please let the purified water flow for at least 60 seconds;
3. Before use every day, please let the purified water flow for at least 10 seconds before use (to drain stagnant water);
4. When the water purifier is not used for more than two days, please let the purified water flow for at least 60 seconds before use (to keep the water outlet clean);
5. Please use “Contained Purified Water” as soon as possible. Because there is no residual chlorine in purified water, the bacteria may breed easily, put it into a clean
container with a cover and store it in the refrigerator.
6. Please do not touch the “Purified Water” outlet to avoid bacterial growth;
7. If there is a lot of turbidity in tap water (e.g. the water tank is cleaned or tap water is not used for a long time, etc.), please allow the tap water to flow for some time
before use of “purified water” to shorten the life of filter cartridge;
8. This product is a household water purifier, please never use it for any purpose other than cooking or drinking;
9. Never connect a special faucet to other machines such as gas water heaters
to avoid damage to other machines;
10. Please do not install the machine near flame or high temperature;
11. When the flow of purified water becomes less, please replace the filter. The filter shall be replaced regularly;
12. Please press slowly when adjusting the raw water and purified water buttons to avoid damage to the machine body;
13. When used in areas with high water pressure, please turn down the water flow before using. In case of large flow of water, water purification capacity may be affected,
and too high water pressure can cause damage and leakage. The conventional water pressure of the product is 0.1-0.4MPa;
14. To avoid damage to the container, never freeze the product;
15. When using “purified water”, never use hot water exceeding 38 degrees. If hot water passes through the water purifier accidentally, there may be temporary smell in
water sometimes;
16. Do not plug the water outlet, or have it connected with other device to avoid damage to the water purifier body;
17. Do not use steel balls, cleaning agents or aggressive liquids (such as gasoline or alcohol) for scrubbing. These substances may cause product rupture, scars,
discoloration or deformation;
18. Please do not disassemble the water purifier body and the filter (if there is
any abnormality, please refer to the catalog, Page 9: Abnormal condition and troubleshooting).

Six adapters and 1 universal connector supplied with the water purifier may be easily mounted on majority of threaded faucets;
Faucets that cannot be installed are: sprinkler pull-our faucets, faucets with rectangular or elliptical outlets, sensing faucets, or faucets in diameter out of 15-24mm
with a throat depth less than 15mm;
2. The replacement period of a filter may vary with water amount consumed, water quality and water pressure;
3. It shall not be installed on a hot and cold faucet;
4. The water purifier shall not be in a position exposed to direct sunlight, as this may cause deformation and discoloration;
5. Hard water cannot be converted into soft water, and salt (sea water) or metal ions dissolved in water cannot be removed;
6. The filter cartridge shall be cleaned and replaced on a regular basis.
