CONNECTING THE WATER LINE
We recommend using a flare nut wrench to connect the water line fittings. After the valve
has been installed on the water line, it must be flushed before connecting it to the
refrigerator Remove the plastic cap from the water valve on the back of the refrigerator.
Attach the water supply line to the valve. Open the valve and flush out the supply line
before attaching it to the refrigerator. Attach the supply line to the water valve on the
back of the refrigerator. Tighten all connections. Turn on the water and check for leaks.
Press the water dispenser button and bleed all the air through the system. When water
begins coming out, run another quart to be sure all the air is out of the line. Turn the
icemaker on and cycle it manually until water fills the tray to ensure all the air is out of
the line.

Various connector types are available.
These illustrations show a saddle valve with
the water line connected using a
compression fitting at each end.
The additional coil of tubing (approx-
imately 7 feet or 2.1 m) is to allow pulling
the refrigerator out for servicing or
cleaning.
We recommend the use of a pre-assembled
braided plastic or nylon line with threaded
couplings on both ends to prevent leakage
and pop offs.
