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:

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.

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.
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.
