3. Shut o the water supply and remove the faucet hose. (Figure 1)
4. Connect the feed water adapter and ensure that the rubber O-ring is loaded.
• If the angle valve outlet is 3/8”, connect it to the water supply and faucet hose directly.
• If the angle valve outlet is 1/2”, you need to remove the above two ttings before connection. (Figure 2)
Step 3: Install the faucet
Note: If there is no hole in your kitchen sink or countertop, you have to drill one (1")or use the hole for
the soap dispenser.
Installation of the lter system
Step 1: Fix the lter head and the lter
1. Paste the assistant label to nish drilling. (Note: Mount the
water lter at least 2 inches higher than the ground for easier lter
change.)
2. Install the screw and reserve enough space to hang the lter.
3. Hang the lter system on the screw.
Step 2: Connect the water supply (cold water only)
1. There is an existing mark at the end of the tubing for you to
conrm if the tubing is fully inserted into the tting.
2. Connect one end of the 1/4" PE tubing to the inlet of the lter
head. Until you reach the mark on the tubing.

WD-UB system | Installation Instructions
Note:
1. If using well water as the source, please make sure the feed water has been through a pre-ltration system, otherwise,
large particles in well water will clog the lter easily and shorten lter life.
2. The above form lists model numbers of only black lters. Please note that the white lter is dierent from the black
lter only in color. They have the same lter material and ltration capacity.
3. Actual lter life varies according to local water quality.
Precautions
• Do not use it with water that’s microbiologically unsafe or of unknown quality without adequate disinfection.
• For use only with cold water.
• Do not freeze the lter, as this can cause cracking and water leakage.
• Do not allow children under 3 years old to have access to small parts during installation of this product.
• This installation must comply with all applicable state and local regulations.
• Turn o the water supply while replacing the lter.

Frequently asked questions
Q: What should I do if water leaks after installation?
A: In the event of water leakage, turn o the water supply. If the water leakage is occurring at the
thread, wrap Teon tape on the external thread. If the water leakage is occurring at the quick
connection position, insert the quick-connect tting to the end and make sure the hoses hit the
bottom of the tting. Contact us for solutions if the water leakage persists.
Step 4: Check the leaks and ush the lter
1. In the event of water leakage, turn o the water
supply. If the water leakage is occurring at position
1, wrap Teon tape on the external thread. If the
water leakage is occurring at position 2, 3 or 4,
check whether the tubing is fully inserted into the
ttings. If not, insert it again until you reach the
mark on the tubing.
2. Flush the lter for 5 minutes before use.
To disconnect
Use your thumb and index nger to press down on the lock sleeve. Use your other hand to pull out the
hose from the tting.
Note: Please do not pull out the tubing directly, or else it will damage the tting and cause leakage.

Q: Why doesn’t the TDS value lower after ltration?
A: The main purpose of this waterdrop lter is not to remove TDS. TDS stands for total dissolved solids,
and it is basically composed of inorganic salts and a small amount of organic matter. The lter can
remove harmful substances while keeping benecial trace elements. Please choose Waterdrop RO
system if you are looking for physical removal of TDS.
Q: When should I replace the lter?
A: The lter's service life is related to water quality. If the ow rate is signicantly reduced or if the
water has a peculiar smell, we suggest that you replace the lter. The recommended service life of the
lter is as follows: 1 year for WD-RF10-UF, WD-RF10-MZ, 2 years for WD-RF15-UF, WD-RF15-MZ, 3 years
for WD-RF17-UF, WD-RF17-MZ.
Q: Why does black water come out during ushing?
A: It’s normal that black water comes out when ushing. The purpose is to remove carbon powder
remaining on the surface of lter materials. You can normally use it after ushing for 5 minutes.
1 -year quality assurance
All mechanical devices with moving parts have a normal life span and will need to be replaced periodically. For
this reason, mechanical devices such as water ttings, lter head, and faucets have a limited replacement
assurance of 1 year. No assurance is given as to the service life of any lter cartridge, as the service life will vary
based on local water conditions and water consumption.
If the product proves to be defective within 1 year from the date of purchase, please contact our customer
service department. During the assurance period, we will replace or repair any part that is deemed to be
defective if the product has not been subjected to tampering, alteration, or improper use after delivery, and
has not been repaired by the manufacturer.
We do not make any promises in the event of misuse, use in abnormal temperature conditions, conditions
outside those listed in the operating parameters, or use in commercial operations.
WARNING Please read it carefully before installation.
The system and installation shall comply with applicable state and local regulations.
