To install an under sink water filtration system, you'll need to shut off the water supply to the sink by locating the shut-off valves under the sink and turning them clockwise.
First, identify the type of system you have: a countertop or a wall-mounted system. Countertop systems are typically easier to install and require less plumbing expertise.
For a countertop system, you'll need to attach the filter housing to the sink using the included mounting clips and screws. The housing should be securely attached to prevent leaks.
Next, connect the water supply lines to the filter housing, making sure to use the correct fittings and tighten them firmly.

Preparation
Before you start installing your under sink water filtration system, it's essential to prepare the area. Locate the cold water valve under your sink and turn it clockwise to shut off the water supply, preventing any leaks while you work.
Make sure you have all the necessary tools and equipment within reach, including a wrench or pliers to loosen any connections.
Disabling and Enabling Water Supply
To disable the water supply, locate the cold water valve under your sink and turn it clockwise. This will prevent any leaks while you work.
You can install an under-sink water filter system yourself, but it's probably not the best DIY project. Drilling holes in your sink and connecting water lines are not for everyone.
To enable the water supply, start by turning on the main water supply to your house. Then, turn on the valve under your sink, and if your filter system has a separate faucet, open it up as well.

Mounting and Connecting the Unit
Mount the filter unit to the cabinet wall using the provided bracket and screws, ensuring it's easily accessible for future filter changes and securely fastened.
Make sure the connections are tight but not overly tightened to ensure proper water flow when attaching the filter's tubing to the T-adapter and the shut-off valve.
Identify the inflow and outflow ports on the filter and attach the faucet's tubing to the outflow port and the cold water feed line to the inflow port to connect the filter unit to your plumbing system.

Use a marker or pencil to mark where you plan on mounting the unit, then drill pilot holes and screw in the wall anchors to mount the filtration unit on the wall.
Join the filter's tubing to the T-Adapter by lining up the tubing with the correct opening on the adapter and giving it a good push until it's snug.
To ensure a proper installation, verify for any leaks after opening the cold water supply back on, and if no leaks are present, open the filtered water faucet for 10 minutes as specified on the manual to clean the filter and the lines of any debris.
Connecting Tubing and Fittings
Connecting tubing and fittings is a crucial step in installing your under sink water filtration system. Make sure to attach the filter's tubing to the T-adapter and the shut-off valve, ensuring the connections are tight but not overly tightened to allow for proper water flow.
The T-adapter is a key component in this process, and you'll need to join the filter's tubing to it. Simply line up the tubing with the correct opening on the adapter and give it a good push until it's snug.
To connect the filter unit to your plumbing system, identify the inflow and outflow ports on the filter. Attach the faucet's tubing to the outflow port and the cold water feed line to the inflow port, making sure all connections are secure to prevent leaks.
Tightening the connections is important, but be careful not to overtighten them, as this can restrict water flow. By following these steps, you'll be able to connect your tubing and fittings with ease.
Faucet and Cartridge Installation
To install the faucet, you'll need to drill a hole in your countertop or use an existing one, then secure the faucet in place with the provided hardware and connect the filter tubing to the faucet base.

Drilling a hole can be a bit tricky, but it's essential to get it right. Make sure to follow the manufacturer's instructions for the correct hole size and placement.
Once you've secured the faucet, you'll need to install the remaining tubing to the right side of the filter's home. This involves installing an adapter on the remaining side of the tubing, which requires a nut, plastic stop washer, and insert. Remember to use pliers to create a tight install, but avoid over-tightening.
After installing the faucet and tubing, you're ready to insert the filter cartridges. Start by taking out the first three-stage filter element, which consists of a PP cotton filter, granular activated carbon filter, and compressed activated carbon filter. Remove the protective packaging film from each element before proceeding.

Insert Cartridges
To insert the filter cartridges, start by taking out the first three-stage filter element. This element consists of 1 PP cotton, 1 granular activated carbon, and 1 compressed activated carbon.
Remove the protective packaging film on the surface of each filter element. The PP cotton filter element will be placed in the first level, the granular activated carbon filter element in the middle No. 2 position, and the compressed activated carbon filter element in the third level.
Align the center of the filter element with the positioning ring at the bottom of the filter bottle, and the upper end with the positioning ring in the head cover. Use the filter bottle wrench to tighten it clockwise.
