The water tube is made of polypropylene with
an overmolded santoprene nozzle. Due to the
rigid nature of the polypropylene, this tube is
mated to a more flexible polyethylene tube with
a John Guest fitting high on the back panel.
This change of material is necessary to pre-
vent kinking when the tubing is attached to the
water valve. Water Delivery
Water is delivered to the ice maker mold by
means of a “tube-within-a-tube” design. A con-
duit system consisting of three separate pieces
(liner fitting, conduit, back panel fitting) is
foamed into place in the cabinet.
This conduit provides a pathway from the
freezer liner to the back panel. The majority of
this system is routed above the refrigerator liner
to prevent the water tubing from freezing. The
tubing that delivers the water is routed through
the conduit, and is secured by snapping into
place at the freezer liner fitting.
