WATER SUPPLY LINE
For all ice machine models, locate the water supply line as
shown in the illustration below.
IMPORTANT NOTE:
It is recommended that the water
supply be placed in an adjacent cabinet within the shaded
area shown in the illustration. If placed within the opening,
additional cabinet depth may be required.
The water supply line should be connected to the house
supply with an easily accessible shut-off valve between
the water supply and the ice machine. A reverse osmosis
system can be used, provided there is constant water
pressure of 20 psi
(1.4 bar)
to 80 psi
(5.5 bar)
supplied to the
unit at all times. A copper line is not recommended for this
application.
