INSTALLATION
STEP 1: Install cold water supply valve
STEP 2: Install drain adapter
STEP 3: Install faucet
STEP 4: Make tubing connections
STEP 5: Install RO assembly
STEP 6: Put system into operation
NOTE: Consult a licensed plumber if you are not familiar with
plumbing procedures.
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
type of valve that will be used. Install a valve on the cold water
supply pipe to adapt 1/2-inch 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-inch (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-inch 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.
5. Connect the blue 3/8-inch product tubing by firmly pushing it into
the connector.
6. Push the black 3/8-inch tubing onto the small hose barb. The red
1/2-inch tubing is pushed onto the large hose barb.
7. Put the faucet into position.
8. The horseshoe clip is positioned around the threaded pipe under
the sink and above the standoff. This clip should engage the
tubing connected to the air gap.
9. Tighten the nut against the clip to hold the faucet in position.
