Installation Information
Electrical Requirements
A 115 V AC, 60 Hz, 15 amp circuit breaker and electri-
cal supply are required. A separate circuit, servicing
only this appliance, is required.
All Sub-Zero Built-In models are equipped with a power
supply cord with a 3-prong grounding plug, which must
be plugged into a mating 3-prong grounding-type wall
receptacle. Follow the National Electrical Code and
local codes and ordinances when installing the recepta-
cle. For location of the electrical supply, refer to the
Finished Rough Opening Specifications illustration for
your specific model.
IMPORTANT NOTE: A ground fault circuit interrupter
(GFCI) is not recommended and may cause interruption
of operation.
DO NOT USE AN EXTENSION CORD OR TWO
PRONG ADAPTER.
REQUIRED ON THESE APPLIANCES.

The outlet must be checked by a qualified electri-
cian to be sure that it is wired with the correct
polarity. If the power and neutral polarity are
reversed at the outlet, the appliance will not oper-
ate. Verify that the outlet provides 115 V AC and is
properly grounded.

Plumbing Requirements
All Built-In models with an automatic ice maker are also
equipped with a factory installed, microbiological water
filtration system. This system operates on water pres-
sure between 30 psi (2.1 bar) to 100 psi (6.9 bar).
IMPORTANT NOTE:
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. If a reverse osmosis system is used, it is rec-
ommended that the water filter be bypassed. Refer to
Water Filter Bypass Plug Installation instructions on the
following page.
Rough in the cold water supply line using 1/4" OD cop-
per line. The water line should be routed up through
the floor within 1/2" (13) from the back wall and no
higher than 3" (76) off the floor. If the water line comes
through the wall, make sure it is no more than 3" (76)
from the floor.
Regardless of the routing, allow 3' (.9 m) of excess cop-
per tubing to remain outside the wall or floor for easy
connection to the unit. The water supply line should be
locate within the shaded area indicated in the Finished
Rough Opening Specifications illustration for the specif-
ic model.
An easily accessible shut-off valve should be used
between the water supply and the unit. Do not use self-
piercing valves. A saddle valve kit (part #4200880) is
available from a Sub-Zero dealer or parts distributor.
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 dam-
age the ice maker and lead to poor ice quality. If a soft-
ened water supply cannot be avoided, be sure that the
water softener is well maintained and operating proper-
ly.
