To disconnect:
1. See Figures 2 and 3. Remove the blue lock clip from the fitting.
2. With the blue lock clip removed, use your thumb and index finger to hold down the lock
sleeve. This will release the metal teeth holding the tube in place. While holding the lock
sleeve down with that hand, use your other hand to remove the tube from the fitting.
How to connect the compression fitting
A compression fitting is used to connect the PVC tubing to the threaded metal inlet with a tapered
open end, such as the refrigerator water inlet, etc.
Figure 4
1. Slide the brass nut and tube collar onto the tube.
2. Fully insert the tube insert into the end of the tube.
3. Slide the tube collar towards the tube insert until it stops.
4. Insert the tube into the tapered, open end of the threaded metal inlet as shown in the picture.
5. Screw on the brass nut and tighten it up. The brass nut compresses the plastic tube collar
onto the tapered metal surface and creates a water seal between them while the tube insert
stiffens the tubing.
How to drill a ½” hole in your sink or counter-top
1. It’s highly recommended to watch the YouTube video “How To Drill Faucet Holes” to
get a better understanding of the process. Depending on what kind of countertop you have,
you may want to hire an experienced professional to ensure the hole is drilled correctly.
2. Choose a half inch Diamond Core Bit for granite, and a titanium drill bit for steel. Do NOT
use a hammer drill on nature stone, glass, and ceramic.
3. An indent should be made with a punch on steel before drilling to help guide the bit.
4. Use caution when drilling on a Porcelain sink, as it could be easily chipped. Set drill speed
on slow. Press the bit downward firmly until breaking through the slippery surface. Some
people found it is easier to secure the bit by drilling through a piece of wood that is firmly
pressed on the surface.
5. Use coolant to disperse heat. Choose water for granite, and oil for steel. Use the Water
Suction Cup to hold coolant inside and prevent the drill bit from slipping.
6. Starting at slowest speed, hold the drill firmly and vertically and prevent the drill bit from
slipping on the counter.
7. Once breaking through the smooth surface, swirl the drill a little to apply pressure in a circle
evenly.
8. Be patient and deliberate. It can take 20 – 40 minutes to drill through one inch.
