Plumbing Requirements
All built-in models with an automatic ice maker come with
a microbiological water filtration system. The water supply
line should be located within the shaded area shown in the
illustration. The water line should be connected to the
house supply with an easily accessible shut-off valve
between the supply and the unit. Do not use self-piercing
valves. A saddle valve kit (4200880) is available from your
Sub-Zero dealer. The water supply line must not interfere
with installation of the anti-tip brackets.
IMPORTANT NOTE: A reverse osmosis system can be
used provided there is constant water pressure of 30 psi
(2.1 bar) to 100 psi (6.9 bar) supplied to the unit at all
times. In this application, the microbiological water filtra-
tion system should be set to bypass mode by removing
the water filter cartridge and inserting the bypass plug
(7011209) available from your Sub-Zero dealer. Installation
instructions packed with the unit will outline this
procedure.
IMPORTANT NOTE: All installations must meet local
plumbing code requirements.
It is not recommended that the ice maker be connected to
a softened water supply. Water softener chemicals, such
as salt from a malfunctioning softener, can damage the ice
maker and lead to poor ice quality. If a softened water
supply cannot be avoided, be sure that the water softener
is well maintained and operating properly.
