3. Install Feedwater Valve (Refer to Figure 5, Page 7)
Warning: Make sure cold water valve is turned off under the sink.
A. Most sinks use 3/8” copper tubing. Connect the saddle valve as shown in Figure 5, Page 7. The back
saddle bracket can be reversed for smaller pipe sizes (7/16” to 1/2”). Tighten screws evenly and
firmly, brackets should be parallel.
B. To pierce soft copper tubing, turn handle to the right several times until it stops. The valve is now
closed. Turning the handle to the left will open the valve.
C. Assemble insert, plastic sleeve and compression nut as shown onto yellow tubing and fasten securely to
saddle valve.
Note: Some states and plumbing codes prohibit the use of saddle valves. Installation must comply with
existing state and local plumbing codes.
4. Making Connections (Refer to Figure 6, Page 8)
Note: Be sure to arrange tubing so there are no sharp bends and leave some “play” in the tubing for ease
of service. Try to keep tubing from the unit to the faucet as short as practical for good flow. If necessary,
refer to the enclosed diagram (Figure 1, Page 5) on the use of “Push In” plastic fittings.
A. Connect yellow 1/4” tubing from saddle valve to the “Push In” fitting on the left side of the bracket
assembly. THE YELLOW TUBE MUST GO UP AND THROUGH THE BASE OF THE BRACKET.
NOTE: Failure to route the tubing through the bracket will not allow protective shroud to be fastened
securely to the bracket.
B. Connect the blue 1/4” tubing from the base of the faucet to the “Push In” fitting attached to the base
of the shutoff meter.
Installing Filter Cartridge & Replacing Filter Cartridges
C. In order to assure proper performance it is essential that “Filter 1” be installed on the left and “Filter 2”
on the right side of the bracket assembly. Use the color/number coded labels to match “Filter 1”
cartridge with “Filter 1” head.
D. Meter should be set at 625 gallons (2366 liters).
5. Test System
A. Open cold water valve under the sink.
B. The system will pressurize. Check for leaks. If any leaks are present, refer to the Troubleshooting Section.
6. Flush Filter
A. Pressing down on the faucet lever will dispense water until you let go. Lifting up on the lever will lock the
faucet open.
B. Run water through the drinking water system faucet for at least five (5) minutes to remove any
trapped air and carbon fines. At this point, the water will run clear. Residual air bubbles in water may
take a week or more to totally go away.
C. The system installation is now complete and ready to serve filtered water.
Enjoy!
