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 supply 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 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
(7005018) available from your Sub-Zero dealer. Installation
instructions packed with the unit will outline this
procedure.
