Installation Instructions
Step 1: Lid Knob Assembly
Insert the Lid Knob (1) into the Lid (2) and secure it with the Knob Screw (4). (Diagram 1 shows this assembly).
Step 2: Spigot Assembly
Insert the Spigot (15) into the hole on one side of the Lower Chamber (10), and tighten the Spigot Hex Nut (11) with the attached Wrench (13). (Diagram 2 shows this assembly).
Step 3: Flush Filters
Carbon Filter Flushing
Soak the Carbon Filter (5) for 60 seconds before priming. Loosen the Wing Nut (8) to the top position, leaving space to hold the Priming Washer (14) in place, and screw the Priming Washer (14) above the Wing Nut (8). Attach the Carbon Filter (5) to the water outlet of your faucet to form a tight seal with the Priming Washer (14). If the seal fails, adjust the Wing Nut (8) upwards again. Flush the Carbon Filter (5) for at least 60 seconds or until the water runs clear. (Diagram 3 illustrates this).
Fluoride Filter Flushing (WD-TK-F/WD-TK-FS models only)
Attach the Fluoride Filter (9) to the water outlet of your faucet, making a tight seal with the Priming Washer (14), and flush the Fluoride Filter (9) for at least 120 seconds or until the water runs clear. (Diagram 4 illustrates this).
Step 4: Filter Installation
Carbon Filter Installation
Insert the threaded rod of each Carbon Filter (5) into a hole in the Upper Chamber (6) and secure it with the Filter Washer (7) and the Wing Nut (8) sequentially. (Diagram 5 shows this).
Fluoride Filter Installation (WD-TK-F/WD-TK-FS models only)
Place the Upper Chamber (6) upside down, and screw each Fluoride Filter (9) with the "IN" indicator to the threaded rod of the corresponding Carbon Filter (5). Flip the Upper Chamber over for installation. (Diagram 6 shows this).
Step 5: Upper and Lower Chamber Assembly
Place the Upper Chamber (6) gently into the Lower Chamber (10), cover it with the Lid, and put the Lower Chamber (10) onto the Stand (12). The Stand (12) is only applicable to WD-TK-S/WD-TK-FS models. (Diagram 7 shows this assembly).
Step 6: Flush the Filtration System
Fill the Upper Chamber (6) with water, then empty the first bucket into the Lower Chamber (10) and repeat the process. You can drink water from the King Tank after flushing it 2-3 times.
Operation and Use Tips
- Check that the spigot (15) is closed during the first operation and after each re-priming.
- The height of the water level in the lower chamber is indicated by the red ball in the water level tube. Fill the upper chamber with water to the height of the floating ball. If the red ball is at its highest point, do not add water.
- If you intend to leave your system unused for more than three days, empty both the upper and lower chambers, remove all filtration elements, and let the components dry.
- Do not use with microbiologically unsafe or unknown quality water without adequate disinfection before or after the system.
Maintenance
- The whole system should be cleaned at least once a month. Before cleaning the chambers, remove the filter cartridges, spigots, and other attached components.
- For sanitizing, add 16 drops of bleach per gallon of water. Remove all parts and attachments before cleaning the stainless-steel chambers in the dishwasher.
- Unused filters can be kept in their original packaging indefinitely. Never put the filter in the freezer, and always re-flush it before using it again.
Frequently Asked Questions
Q: Why does the flow get slow?
Possible reasons include: The carbon filter may not be installed correctly. If the filter produces microbubbles, remove it, soak in water for 10-20 seconds, and reinstall. The filter's surface may become logged with particulate matter, reducing flow; replace the filter regularly based on its lifespan.
Q: Why does my water filtration system leak where the upper and lower chambers meet?
There is a water-tight seal between the upper and lower chambers. Water can spill after the lower chamber is filled. Pay close attention to the water level change in the upper chamber.
Q: Why does the upper chamber still contain water after the filtering process ends?
It is normal for one to two inches of water to remain in the upper chamber. Because this system is gravity-fed, as the water level in the upper chamber drops, the filtering process naturally slows down due to less water pressure.
Q: Why is filtered water in the lower chamber cloudy?
Cloudy water may indicate that filters still contain manufacturing dust and need to be flushed more thoroughly. If the water filtering through the filters remains cloudy, contact Customer Service at 1-888-352-3558 (US).
Q: Why is the TDS value not reduced after filtration?
Total Dissolved Solids (TDS) are mobile charged ions dissolved in water, including minerals, salts, and metals. The gravity-fed water filter system filters out harmful substances while preserving beneficial minerals. If you are looking for water purifiers to reduce TDS, a Reverse Osmosis (RO) water filtration system is a better option.
Q: My filtered water has an unexpected taste. What can I do?
A. Follow the Carbon Filter Installation steps to ensure the filter is properly installed and filtering the water. B. Flush the filter for another 1-2 minutes.
Note: The fluoride removal test is carried out under standard conditions of a third-party laboratory, and actual results may vary.
