INLET ADAPTER VALVE INSTALLATION
NOTE: This assembly is offered as an optional installation method. Make sure it is approved for use under
State and local plumbing codes before ordering kit (P/N 42500004).
NOTE: Use this assembly on U.S.N.P.T.* pipe thread fittings only.
1. CAUTION: If no shut off valve is installed under sink,
close main water valve during this installation.
Locate shut off valves on water lines under sink. To
identify hot supply pipe and cold supply pipe, turn both
faucets on and let water run. As water flows, hot water
pipe becomes noticeably warmer.
2. CAUTION: do not install feed water assembly on hot
water
line.
Turn off cold water supply by closing shut off valve.
Drain line by opening sink faucet. Some mixing type
faucets may also require turning off hot water supply.
NOTE: All item callouts refer to Figure 4 unless noted
otherwise.
3. CAUTION: Place container or towel below shut-off
valve to catch any water remaining in pipe.
Disconnect cold water supply line to sink at inlet valve
end of line.

angle (90º) to valve body.
11. CAUTION: Do not open valve until system is
activated (Page 10).
