PRO 48 Site Preparation
Plumbing Requirements
The PRO 48 has an automatic ice maker with an integrated
water filtration system. The water supply line should be
located within the shaded area shown in the illustrations.
The water line must not interfere with installation of the
anti-tip bracket.
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 is available through your authorized
Sub-Zero dealer.
A reverse osmosis system can be used, provided there
is constant water pressure of 20 psi (1.4 bar) to 120 psi
(8.3 bar) supplied to the unit at all times. In this applica-
tion, the water filtration system must be bypassed. Refer
to water filter bypass mode on page 16.
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, make sure that the water
softener is well maintained and operating properly.
IMPORTANT NOTE: Do not use with water that is microbi-
ologically unsafe or of unknown water quality without
adequate disinfection before or after the system. Systems
certified for cyst reduction may be used on disinfected
waters that may contain filterable cysts.
