Step 1: Install cold water supply valve
Comply with local plumbing codes. A typical connection using a water supply valve is shown in Figure 5.
Water supply valve
NOTE: Be sure to turn off the water supply and open a low
faucet to drain the pipe.
Cold water pipes vary in size and style. The installer will
determine the type of valve that will be used. Install a valve on
the cold water supply pipe to adapt 1/2" OD tubing. If threaded
fittings are used, be sure to use pipe joint compound or Teflon
tape on outside threads. Turn the valve off.
Step 2: Install drain adapter
Follow the instructions in the Appendix for installation of the
Drain Boa™, if used.
The drain adapter is designed to fit 1"1/2 (3.8 cm) sink drain
pipe. The adapter installs directly to the sink tailpiece.
Step 3: Install faucet
A. Prepare mounting hole
1. Select a location for the faucet. Be sure it will fit flat against
the sink or counter and that there is space underneath for
tubing.
2. If drilling is needed, make a 1"1/2 diameter hole.
WARNING:
To avoid damaging a sink, consult a qualified
plumber or installer for the proper method of drilling
holes in porcelain or stainless steel.
B. Assemble faucet
The tubing and fasteners are assembled to the faucet before the faucet is placed in position. This can be
done above the sink.
1. Slide the decorative ring over the tubing connections and up to the bottom of the faucet.
2. Slide the gasket over the tubing connections and up to the bottom of the faucet.
3. Slide the standoff onto the threaded tube, followed by the standard washer, the lock washer and nut.
4. Screw the threaded hose connector on the end of the threaded tube.
