height of the Priming Washer (14), and screw the Priming Washer (14) above the Wing Nut (8).
2.Attach the Carbon Fiber (5) to a water outlet of your faucet to make a tight seal by means of the
Priming Washer (14); if tight seal fails, adjust the Wing Nut (8) upwards again.
3.Flush the Carbon Fiber (5) for at least 60 seconds or until the water runs clear.
Fluoride Filter * (Only applicable to WD-TK-F/WD-TK-FS)
“Attach the Fluoride Filter (9) to the water outlet of your faucet to make a tight seal by means of the Priming

Do not use with water that is micro-biologically unsafe or of unknown quality
without adequate disinfection before or after the system.
NOTE:

Operation and Use Tips
1. Ensure that the spigot (15) is in the closed position during the rst time operation and after each
re-priming.
2. The red ball in the water level tube indicates the height of the water level in the lower chamber. Add
water into the upper chamber according to the height of the oating ball. Do not add water if the red
ball is in the highest point .
3. If you plan to leave your system unused for more than three days, empty both the upper and lower
chambers, remove all ltration elements, and allow the components to dry.
4. Do not use with water that is microbiologically unsafe or of unknown quality without adequate
disinfection before or after the system.
Maintenance
1. The whole system should be cleaned at least once a month.
• Remove the lter cartridges, spigots and other attached components rst, and then clean the
chambers with water and dish soap.
Frequently Asked Questions
Q: Why is the ow rate slow?
A: To determine if the carbon lter have been successfully installed
B: If the lter produces microbubbles, please take down the lter, soak it in water for a period of time,
and reinstall it.
C: Small particulate matter can be trapped on the outside of the lter cartridge causing the ow rate
to decrease. Replace the lter in time according to the lter lifetime.
Q: Why does my water ltration system leak where the upper and lower chambers t together?
A: There is not a water-tight seal between the upper and lower chambers of the system. After the lower
chamber is lled with water, water inside can spill over. Please pay attention to water level change of
the faucet.
Q: Why does the upper chamber still contain water after ltering the process?
A: It is normal for one to two inches of water to remain in the upper chamber. This system is gravity
lters and as the water level in the upper chamber decreases the ltering process will naturally slow
down because there is less water pressure available to force water through the elements.
2. Storing the Filter
• Unused lter can be stored indenitely in their original packaging. Do not store with fragrant items.
• Do not store the lter in the freezer.
• Always re-ush the lter before using again.
If the water for cleaning contains viruses or bacteria, add 16 drops of bleach
to per gallon of water. If the stainless steel chambers are cleaned in the dishwasher, remove
all parts and attachments rst.
NOTE:

Q: Why is ltered water in lower chamber cloudy?
A: Cloudy water may indicate that lters still contain some manufacturing dust and require additional
ushing. If the water ltering through lters continues to be cloudy in appearance, contact Customer
Service 1-888-352-3558 (U.S.).
Q: Why is the TDS value not reduced after ltration?
A: Total Dissolved Solids(TDS) are the total amount of mobile charged ions including minerals, salts or
metals dissolved in a given volume of water. The gravity-fed water lter system reduces harmful
substances and remain benecial minerals. If you are looking for water puriers to reduce TDS, please
choose the RO water ltration system.
Q: My Filtered Water has an unexpected taste, what can I do?
A. To ensure the lter are properly ltering the water, follow the Carbon Filter Installation to check if it’s
properly installed.
B. Flush the lter for another 1-2 min.
