A. PREFERRED INSTALLATION

Utilizing existing kitchen sink water supply valve
and removable faucet tubing.
A typical connection using the included water supply
fitting is shown in the illustration below.
1. Close the water shut-off valve that is
immediately in front of the supply tube and
open the faucets to drain water from the sink
cold water pipe.
2.
Remove the nut that connects the cold water faucet
to the supply tube. Some water may spill out.
NOTES:
• Be sure to turn off the water supply and open
a faucet to drain the pipe.
• Make sure the gasket is installed in the water
supply fitting.
3.
Hand-tighten the water supply fitting onto the cold
water faucet. Be sure the gasket, as shown, is in
place before final assembly. Finish tightening with
an adjustable wrench. Be careful not to
overtighten or cross-thread, since damage to the
threads can occur. Make sure the 1/4”quick
connection is not against a wall that causes the
supply tubing connection to bend. A quarter turn to
tighten or loosen the adapter may be necessary to
avoid this.
4. Reconnect faucet tubing line to the fitting.
5. Install tubing. (See Installingthetubing section.)
