Installation Tips
How to use the quick-connect fittings
To connect to tubing
1. Push the tubing into the fitting around 4/5" until the tubing is fully inserted.
2. When the tubing is fully inserted, put the blue lock clip on the fitting. It will lock the tubing
in place and prevent it from falling off.
INSTALLATION INSTRUCTIONS
How to drill a hole in your sink or countertop
1. Select the desired location for the drinking faucet on the counter top near the sink.
2. Use a power drill to drill a 1" diameter hole for installation.
To disconnect from tubing or plugs
1. Remove the blue block clip from the fitting. Please skip this for plugs.
2. Use your thumb and index finger to press down the lock sleeve. Use your other hand to
pull out the tubing or plugs from the fitting.
NOTE:
If the tubing is not fully inserted, leakage will occur due to a lack of seal created.
NOTE:
Check and cut the tubing end squarely and cleanly with utility knife to the desired
length.
NOTE:
Please do not pull out the tubing or plugs directly. This will damage the fitting and
cause leakage.
Depending on the countertop material and sink type, a professional installer is
recommended to drill a hole for the drinking water Pureit faucet installation.
NOTE:

Incorrect Cutting
Installation Steps
Step 1: Install the RO Filter
1. Locate the recessed handle at the bottom left side of the panel.
2. Pull outward to open the side panel.
3. Take the RO Filter from the package and remove the packaging of the filter.
NOTE:
The RO Filter is provided in separate within the same package.

4. Lift the hoop of the new filter to the full extent and keep it in this position.
5.
Position the bottom of the filter to match a recess in the filter device, then plug the filter tightly
in place.
6. Press down the hoop to the position shown by the dotted line. Tug the filter outward to see
whether it is installed correctly.
7. Install back the left panel.
Step 2: Install the Feed Water Adapter
1. Shut off the cold water supply. Turn on the kitchen faucet to release water pressure.
2. Connect the input water tubing (3/8" PE tubing) to the feed water adapter.
3. Disconnect the cold water pipe from the cold water supply valve.
4. Connect the feed water adapter onto the cold water supply valve (with its washer) and
tighten it with a wrench.
Thread the PE tube through the
nut and cover closely at the
adapter bulge.
Unscrew the nut on feed water
adapter, and slide the nut onto
the 3/8" PE tube.
Use a wrench to tighten the nut,
make sure it doesn't leak.
NOTE:
If you find the tubing difficult to connect, please put one end into warm water for 5
seconds to allow it to soften. Then try again.
5. Re-connect the cold water pipe onto the feed water adapter and tighten with a wrench.

Step 3: Install the Pureit Faucet (Non-Air Gap Faucet)
1. Please check if your kitchen sink or countertop has an existing hole. If not, you will need
to drill one. Please refer to “How to drill a hole in your sink or countertop” on page 7.
2. Insert the soft rubber pad into the screw of the Pureit faucet.
3. Place the Pureit faucet into the countertop hole. Under the sink, put the plastic washer
and fixing nut on the screw and tighten the fixing nut to fasten the Pureit faucet.
4. Connect the 1/4" tubing to the quick connection fitting on the bottom of the Pureit faucet
and put the 1/4" lock clip on the fitting.
Step 4: Install the Drain Saddle
1. Choose a place on the drainage pipe that is convenient for installing the drain saddle and tubing.
2. Select the location of the hole and drill a 1/4’’ inch hole through one side of the drain pipe.
Make sure not to penetrate the opposite side of the pipe.
3. Cut the 1/4" tubing into two. The length should be determined base on how far you plan to
place the device from the filtered water tube and waste water tube. Please refer to the tubing
cut note on page 6.
4. Insert the other 1/4’’ PE tubing as the waste water tubing into the drain saddle. Please push
through 3/5" of the PE tubing into the black sticky pad.
5. Place the extruded portion of the waste water tube from the drain saddle into the hole on the
drainage pipe. Then secure the drain saddle by tightening the two screws and hex nuts.
6. Tug on the 1/4" tube to check and ensure it is properly secured.

on page 6. Connect the 3/8" tubing from the feed water adapter to the pressure relief valve
(Please note the arrow direction on the valve to ensure the direction of water flow is correct.),
then use the other piece of 3/8" tubing to connect the pressure relief valve to the input water
port.
NOTE:
Ensure the tubing is 4/5" inserted into the fitting. Place the blue lock clip into the lock
sleeves to secure the connection.
You can use the 3/8" right angle quick connector to adjust the direction of the tubing.
