Rough in the water supply line. Connect a

OD copper line to the house supply. Be sure to
use an easily accessible shut-off valve between
the supply and the unit. This shut-off valve
should not be installed behind the unit. Do not
use “self-piercing” valves. A saddle valve (part
#4-20-088-0) is available from your Sub-Zero
dealer. A line filter is required when the water
supply has a high mineral content. The water
supply must maintain 20 psi (1.4 bar) to 80 psi
(5.5 bar) of water pressure.
The water supply and drain should be roughed
in and ready at the point of installation. An
electrical outlet directly behind the ice maker
will make the installation easier. All electrical,
water and drain connections must conform to
local codes. For location of the water supply,
refer to the Installation Specifications illustra-
tions on pages 7–8.
IMPORTANT NOTE: Although the Model
315I(P) has been designed to be serviced in
place, in some cases it may be necessary to
pull the unit out for service. For that reason do
not restrict access to the unit at the front, top
and bottom.
If a floor is to be installed after the ice maker,
shims the thickness of the floor should be
installed under the Model 315I(P) to keep the
ice maker level with the floor. Also, allow

(3) clearance on each side of the unit for
protruding screw heads.
Installations on a slab: Use a Model 315IP,
with built-in drain pump and pump the water
to the point of drainage. Drain pump models
will pump one story high.
Installations over a crawl space or
basement: Either a gravity drain (Model 315I)
or a drain pump (Model 315IP) unit may be
used. If there is not enough room behind the
ice maker for a drain/waste water receptacle,
the drain will have to be below the floor.
IMPORTANT NOTE: All plumbing must meet
local codes.

A 115 V AC, 60 Hz, 15 amp circuit breaker and
electrical supply are required. A separate
circuit is required for each unit.
The Model 315I(P) is equipped with a power
supply cord with a 3-prong grounding plug,
which must be plugged into a mating 3-prong
grounding-type electrical outlet.
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 illustra-
tions on pages 7–8.
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.
Shut off the power to the electrical
outlet.
