The PRO 48 has an automatic ice maker. This
system operates on water pressure between
1.4 bar and 8.3 bar.
Rough in the cold water supply line using
OD copper, braided stainless steel or PEX
tubing. The water line should be routed up
through the floor within 13 mm from the back
wall and no higher than 76 mm off the floor. If
you have to come through the wall, make sure
the water line is no more than 76 mm from the
floor.
Regardless of the routing, allow .9 m of excess
tubing to remain outside the wall or floor for
easy connection to the unit. Locate the water
supply line within the shaded area indicated in
the Installation Specifications illustration on
the previous page.
Use an easily accessible shut-off valve
between the water supply and the unit. Do not
use self-piercing valves.
(part #4200880) is avail able from your
Sub-Zero dealer.
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.
IMPORT NT NOTE: Do not use with water
that is microbiologically 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.
MPORT NT NOTE: ll installations must
meet local plumbing code requirements.
IMPORT NT NOTE: reverse osmosis
system can be used, provided there is constant
water pressure of 1.4 bar to 8.3 bar supplied to
the unit at all times.
