Step 3:
To prepare the electrical system, rough in the elec-
trical outlet following the Pre-Installation Specifications.
You will need a 115 volt, 60 Hertz electrical supply. Dedicate
a separate 15 amp fuse or circuit breaker to the Sub-Zero
unit, and follow any local codes that apply.
The Sub-Zero unit comes with a power supply cord with a
three-prong grounding plug. The refrigerator must be
plugged into a mating three-prong wall receptacle ground-
ed in accordance with the National Electrical Code and local
codes.
WARNING
Do not use an extension cord, or two prong adapter.
Electrical ground is required on this appliance.
Do not under any circumstances remove the power sup-
ply cord ground prong.

Step 4:
For units with automatic ice makers, first rough in
the water supply line. Connect a 1/4" copper line to the
house supply. Use an easily accessible shut-off valve
between the supply and the refrigerator. This is usually
about 6" (152 mm) from the compression fitting. The ice
maker operates on water pressure of 20 psi (1.4 bar) to 100
psi (6.9 bar). But don't use a self-piercing valve. See your
Sub-Zero dealer for a saddle valve kit, ask for part number
4200880.

If the local water supply has high levels of sediment, con-
sider adding an in-line filter.
Good water is important for good ice quality. It is not rec-
ommended 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 mold
and lead to poor ice quality. If a softened water supply can-
not be avoided, it is important that the water softener be
well maintained and operating properly.
Reverse osmosis systems 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.
Route the water line through the floor within 1/2" (13 mm)
from the wall and no higher than 3" (76 mm) from the
floor. If the water supply is brought in from behind the unit,
route the water line through the wall no more than 3" (76
mm) from the floor. In either case, allow at least 3' (1 m) of
excess copper tubing outside the wall or floor for easy con-
nection to the refrigerator.
