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.
CAUTION:
DO NOT INSTALL FEED WATER ASSEMBLY ON HOT WATER LINE.
1. 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. 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:
If no shut off valve is installed under sink, close
main water valve during this installation.
Place a container or towel below shut-off valve to
catch any water remaining in pipe.
All item callouts refer to Figure 4 unless noted
otherwise.
3. Disconnect cold water supply line to sink at inlet
valve end of line.
NOTE:
Use Teflon tape (P/N 35700002) on male
threaded connections in Steps 4, 6, 7, and 8.
