SUB-ZERO MODELS 315I AND 315IP INSTALLATION
ICE MAKER REQUIREMENTS
To properly make and store ice, the Model
15I(P) requires access to air, potable water,
3
115 V AC electrical supply and a drain. The
ice maker must be installed indoors, in a
controlled environment.
IR SUPPLY
A
The ice maker uses a fan to take in room air at
the front of the ice maker through the right
side of the kickplate/grille. It discharges warm
air out the left side of the kickplate/grille.
Anything placed in front of the kickplate/grille
will restrict air flow and cause a decrease in
performance and efficiency. The minimum air
temperature the ice maker will operate in is
50˚F (10˚C), and the maximum is 100˚F (40˚C).
WATER SUPPLY
The ice maker requires a continuous supply of
potable water at no less than 20 psi (1.4 bar) of
flowing pressure. Static water pressure should
not exceed 80 psi (5.5 bar). The minimum
water temperature the ice maker will operate
in is 40˚F (5˚C), and the maximum is 100˚F
(40˚C).
WATER QUALITY
There is no such thing as “pure” water. All
water, including potable water supplied by
municipalities, contains some impurities.
ater absorbs impurities fr
W
om the air as rain
and as it flows through the ground. Some of
the impurities ar
e solid particles; these are
known as suspended solids and a fine particle
filter will remove them. Other impurities are
chemically bonded to the water molecules and
cannot be filtered
out; these
are called
dissolved solids.
Ice made by the Model 315I(P) will have a
lower mineral content than the water from
which it was formed.
Water with fewer impurities will freeze more
uickly. This occurs because impurities cause
q
the water temperature to rise. This concentrates most of the impurities in the ice maker
water reservoir where they may form hard
deposits known as scale. The Model 315I(P)
dilutes the concentration of minerals by overfilling the reservoir during the harvest cycle
(with the excess water flowing down the
drain). About three quarts of water flow into
the unit each cycle. About one quart of that
rinses the reservoir and goes down the drain.
Some impurities will inevitably remain and will
stick to the inner parts of the ice maker resulting in malformed ice cubes. Built up mineral
scale can shorten the life of your ice maker.
To keep the ice maker operating properly,
these impurities or minerals will have to be
regularly dissolved by an acid cleaning using
Sub-Zero ice maker cleaner. Directions for
cleaning the Ice Making System are on
page 18.
In general, it is always a good idea to filter the
water. A water filter, if it is the proper type, can
remove taste and odors as well as particles.
Some methods of water treatment for
dissolved solids include reverse osmosis and
polyphosphate feeders. A reverse osmosis
system should include post treatment to
satisfy the reverse osmosis water’s ”aggressiveness”. Deionized water is not r
ecom-
mended.
Because water softeners exchange one mineral
for another, Sub-Zero does not recommend
their use for ice makers. Where water is very
hard, softened water may result in white,
mushy cubes that stick together.
If there are questions about the purity of
your water, contact a local point-of-use water
specialist in your ar
ea for recommendations on
water treatment.

AREA REQUIREMENTS
Before moving the ice maker in place, be sure
the finished opening dimensions, electrical and
lumbing locations are accurate. Refer to the
p
Installation Specifications illustrations on
pages 7–8. The illustrations below provide
verall dimensions for Models 315I and 315IP.
o
Be sure your plumber, electrician and cabinet
installer have this information before finishing
work is completed.
Model 315I is a gravity drain model that
requires a drain tube that is pitched down from
the outlet at the back of the unit to the sanitary
sewer connection. Model 315IP has a built in
drain pump that will pump water up to a drain
point, such as a nearby sink. Refer to specifications on pages 7–8.
IMPORTANT NOTE:
If the ice maker is
installed in a corner, the door swing may be
limited due to handle contact with the wall or
cabinet face.
IMPORTANT NOTE:
ce maker must be at the same level as the
i
The floor under the
surrounding finished floor.
MPORTANT NOTE:When you move the unit
I
using a hand truck or dolly, position the dolly
on the side of the unit and secure the door so
t does not open while transporting the unit.
i
Any finished flooring should be protected
with appropriate material to avoid any
damage fr
om moving the unit.

SUB-ZERO MODELS 315I AND 315IP INSTALLATION
IMPORTANT
NOTE
You must follow
all National
Electrical Code
regulations. In
addition, be aware
of local codes and
ordinances when
installing your
services.
ELECTRICAL REQUIREMENTS
A 115 V AC, 60 Hz, 15 amp circuit breaker and
lectrical supply are required. A separate
e
circuit is required for each unit.
he Model 315I(P) is equipped with a power
T
supply cord with a 3-prong grounding plug,
which must be plugged into a mating 3-prong
rounding-type electrical outlet.
g
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 illustrations 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 twoprong 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.
PLUMBING REQUIREMENTS
Rough in the water supply line. Connect a 1/4”
D copper line to the house supply. Be sure to
O
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 illustrations 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 1/8"
(3) clearance on each side of the unit for
uding screw heads.
protr
Dimensions in parentheses are in
millimeters unless otherwise specified.6
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.

All plumbing must meet
local codes.

(305) fall. An air gap will likely be required
etween the ice maker drain tube and the
b
drain/waste water receptacle. A stand pipe
with a trap below it can be used for the
drain/waste water receptacle.
IMPORTANT NOTE:
Poor drainage will cause
a high rate of ice melting in the ice storage bin.
1)
Place the ice maker in front of the installation opening. Adjust leveling legs to the
approximate height.
2)
Remove the door (with hinges), control
knob, control panel, access panel and lower
face plate.
3)
Route the water inlet line (1/4" OD copper
tube) from the wall through the ice maker
to the front.
4)
Route the drain line from the wall position
through the ice maker. If you have a horizontal run longer than 5' (1.5 m), the drain
should be vented at the back of the unit.
9)
Attach the flare nut to the male flare on the
inlet water valve.
10)
Cut the drain tube to the required length.
11)
Connect the 5/8" drain tube to the storage
bin drain fitting at the bottom of the bin.
Secure with hose clamps. Be sure that the
drain tube is pushed up well past the barbs
on the drain fitting. If needed to ease installation, soak the drain hose in hot water just
before connecting to the fitting.
12)
Turn on the water supply and check for
leaks.
13)
Replace the door (with hinges), control
knob, control panel, access panel and lower
face plate. Level the unit as needed.
