ELECTRICAL REQUIREMENTS
A 115 V AC, 60 Hz, 15 amp circuit breaker and
e
lectrical 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
p
lug, 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 receptacle.
For location of the electrical supply, refer to the
Installation Specifications illustration for your
specific model on pages 5–7.
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. Electrical ground is
required on this appliance. Do not remove
the power supply cord ground prong.
The outlet must be checked by a qualified
electrician to be sure that it is wired with
the correct polarity. Verify that the outlet
pr
ovides 115 volts and is properly
grounded.
PLUMBING REQUIREMENTS
For Built-In models with an automatic ice
m
aker, rough in the water supply line. Connect
a
1
/4" OD copper line to the house supply. Use
an easily accessible shut-off valve between the
water supply and the unit. This valve is usually
placed about 6" (152) from the compression
fitting. Do not use self-piercing valves. A
saddle valve kit (part # 4200880) is available
from your Sub-Zero dealer.
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
supply is brought in from behind the unit,
route the water line through the back wall, no
more than 3" (76) from the floor. Regardless of
the routing, allow 3' (1 m) of excess copper
tubing to remain outside the wall or floor for
easy connection to the unit. For location of the
water supply, refer to the Installation Specifica-
tions illustration for your specific model on
pages 5–7.
A line filter is required when water conditions
have a high sediment content. The ice maker
operates on water pressure of 20 psi (1.4 bar)
to 100 psi (6.9 bar).
A reverse osmosis system can be used,
provided there is a consistent water pressure
of 20 psi (1.4 bar) to 100 psi (6.9 bar) supplied
to the water valve at all times.
IMPORTANT NOTE:
In some cases a reverse
osmosis water filter system may not be able to
maintain the minimum water pressure consis-
tently.
Good water is impor
tant for high quality ice.
It is not recommended that the ice maker be
connected to a softened water supply. Water
softener chemicals, such as salt fr
om a
malfunctioning softener, can damage the ice
maker mold and lead to poor ice quality. If a
softened water supply cannot be avoided, it is
important that the water softener be well main-
tained and operating properly.
