ICE MAKER R E Q U I R E M E N T S
To properly make and store ice, the Model
315I(P) requires access to air, potable water,
115 V AC electrical supply and a drain. The
ice maker must be installed indoors, in a
controlled environment.
Water with fewer impurities will freeze more
quickly. This occurs because impurities cause
the water temperature to rise. This concen-
trates 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 over-
filling 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.
A I R S U P P LY
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).
Some impurities will inevitably remain and will
stick to the inner parts of the ice maker result-
ing 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.
WAT E R S U P P LY
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).
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 ”aggres-
siveness”. Deionized water is not recom-
mended.
WAT E R Q U A L I T Y
There is no such thing as “pure” water. All
water, including potable water supplied by
municipalities, contains some impurities.
Water absorbs impurities from the air as rain
and as it flows through the ground. Some of
the impurities are 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.
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 area for recommendations on
water treatment.
Ice made by the Model 315I(P) will have a
lower mineral content than the water from
which it was formed.

A R E A R E Q U I R E M E N T S
IMPORTANT NOTE: The floor under the
ice maker must be at the same level as the
surrounding finished floor.
Before moving the ice maker in place, be sure
the finished opening dimensions, electrical and
plumbing locations are accurate. Refer to the
Installation Specifications illustrations on
pages 7–8. The illustrations below provide
overall dimensions for Models 315I and 315IP.
IMPORTANT NOTE: When you move the unit
using a hand truck or dolly, position the dolly
on the side of the unit and secure the door so
it does not open while transporting the unit.
Be sure your plumber, electrician and cabinet
installer have this information before finishing
work is completed.
Any finished flooring should be protected
with appropriate material to avoid any
damage from moving the unit.
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 specifica-
tions 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.

A 115 V AC, 60 Hz, 15 amp circuit breaker and
electrical supply are required. A separate
circuit is required for each unit.
Rough in the water supply line. Connect a 1/4”
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 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.

You must follow
all National
Electrical Code
regulations. In
addition, be aware
of local codes and
ordinances when
installing your
services.
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: 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.
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.
Shut off the power to the electrical
outlet.
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
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.

1) Remove the control box cover.
The ice cubes are tapered cylinders about 11/4"
(32) in diameter at the widest end; taper down
to 1" (25) wide at the top; and are 11/8" (29)
high. When the ice maker is adjusted properly,
there should be a 1/4" (6) indent in the base of
the cube. The ice will appear wet when fresh
and may also develop frost on the outside and
look cloudy. This is normal. The frost will
disappear when liquid is poured over the ice.
2) Rotate timer shaft clockwise until the cam is
in the harvest position (switch button out).
3) Turn on the water supply.
4) With unit plugged in, rotate the ice maker
control knob to the ON position.
5) Allow the ice maker to operate for one hour,
and check the size of the cubes; if they are
not correct, adjust as recommended on
page 18.
I C E S TO R AG E B I N
All restaurant-type ice makers, such as the
Model 315I(P), operate on this principal: The
ice storage bin is not refrigerated; instead it’s
heavily insulated, much like a picnic cooler or
ice chest. If the ice storage bin were to be
refrigerated, the ice would freeze together into
one very large cluster of ice and would begin
to evaporate. This would yield ice that is very
poor in quality and difficult to remove from the
ice maker.
6) After the cubes are confirmed to be the
correct size, replace all panels.
U S I N G YO U R I C E M A K E R
The ice maker is extremely simple to use; by
turning the ice maker control knob to the ON
position. The Model 315I(P) will automatically
begin to produce ice and will continue to do so
until the ice storage bin is full.
The Model 315I(P) will continue to operate
until ice builds up high enough to contact ther-
mostat sensor tube in the ice storage bin; then
it will shut off. Models with a drain pump will
occasionally pump out melt water when the ice
maker is off. The pump will only be on for a
few seconds.
Use the scoop to remove ice and place the ice
scoop in the holder provided (do not leave the
scoop on the ice, as it will gradually disappear
into the ice).
The Model 315I(P) will release a batch of eight
ice cubes about every 30 minutes. At the same
time the cubes fall into the ice storage bin,
water will be entering the ice maker and
draining out.
R U N T I M E
The amount of time the Model 315I(P) will run
to replace melted ice is about two hours per
day. The amount of time the ice maker will run
to replace ice removed is dependent upon how
much ice is removed, how clean the ice maker
is, the surrounding air temperature and the
temperature of the water supplied to the ice
maker. An empty ice maker will usually take
about 24–36 hours to refill.
IMPORTANT NOTE: Do not store anything in
the ice storage bin other than ice; items like
wine or beer bottles are not only unsanitary,
but labels may also slip off and plug the drain.

ICE P RO D U C T I O N
Ice production has two distinct cycles: freeze
and harvest. One freeze cycle and one harvest
cycle will yield a batch of eight ice cubes.
H OW T H E I C E M A K E R U S E S WAT E R
The ice maker begins with a fixed charge of
water that is contained in the reservoir. As the
water is sprayed against the freezing surface,
the part of water that does not contain mineral
impurities will freeze and stick to the ice cup
molds. The water containing impurities falls
back into the reservoir. Gradually, during the
freezing portion of the ice making cycle, the
water in the reservoir will become highly
concentrated with mineral impurities.
The freeze cycle occurs when water is sprayed
against the freezing surface. The harvest cycle
occurs when the ice is released and water
enters the ice maker. A complete cycle takes
about 30 minutes.
F R E E Z E C Y C L E
During the freeze cycle the compressor is
pumping refrigerant, the fan motor is blowing
air, and the water pump is circulating water. As
the refrigerated surface absorbs heat from the
water sprayed against it, that heat is moved to
the area where the fan is blowing air. The heat
is transferred to the air, and the warmed up air
is discharged from the ice maker. At the same
time, ice is forming on the refrigerated surface
(located at the upper back of the ice maker).
When the refrigerated surface gets cold
During the harvest cycle fresh water flows into
the ice maker to dilute the reservoir water and
to rinse the concentrated minerals down the
drain.
enough, the ice maker’s timer will begin to
turn. When it turns far enough, it will stop the
freeze cycle and begin the harvest.
H A RV E S T C Y C L E
During the harvest cycle the compressor is still
operating, but the spray pump and fan motor
have stopped. Two other components have
been energized: the hot gas valve and the inlet
water valve. These two valves open and warm
up the freezing surface, allowing the cubes to
fall into the ice storage bin. The timer is still
turning, and when it gets to the end of the
harvest cycle, the freeze cycle will restart.

CLEANING
Make sure that the outside of the unit and
door, ice storage bin, condenser, ice making
system and ice scoop are kept clean.
C L E A N I N G T H E I C E S TO R AG E B I N
The ice storage bin should be sanitized occa-
sionally. It is usually convenient to sanitize the
bin after the ice making system has been
cleaned, and the ice storage bin is empty.
Never allow the ice maker to operate without
regular cleaning. The ice maker will last longer
if it is kept clean. Regular cleaning should be
done at least once per year, and preferably
twice. Some water conditions will dictate more
frequent cleaning of the ice making system
and some carpets or pets will dictate more
frequent cleaning of the condenser.
S I G N AT U R E
P O L I S H
A sanitizing solution can be made of one ounce
of household bleach and two gallons of hot
95˚F–115˚F (35˚C–45˚C) water. Use a clean cloth
and wipe the interior of the ice storage bin
with the sanitizing solution; pour some of the
solution down the drain and allow it to air dry.

Wipe off any spills on the surface of the door
and handle as they occur. If anything spilled on
the door or gasket dries onto the surface, wash
with soap and warm water to remove. Always
use a nonabrasive cloth or pad.
The condenser should be vacuumed two to
three times per year to remove any lint that
may have been drawn into the condenser.
To access the condenser, use a phillips head
screw driver to remove the kickplate/grille.
Then, using a soft bristle brush, vacuum to
remove dust and lint from the condenser. Refer
to the illustration below for location of the
condenser.
To clean the exterior of a stainless steel model,
use a soft, nonabrasive stainless steel cleaner
like Signature Polish (see side note) and apply
with a soft 100% lint-free cloth.
IMPORTANT NOTE: To avoid bending the
condenser fins, be sure to vacuum in the
direction of the fins (up and down).
For maintenance and cleaning, it is
recommended that the circuit breaker to
the unit or the on/off control be shut off.
Failure to clean the condenser could
result in temperature loss or mechanical
failure or damage.

5) Remove control box cover and turn the
timer into the harvest cycle.
4) Turn the ice maker control to ON.
6) With the ice maker operating, blow air
through the inlet water valve; a tire pump
could do the job.
5) Allow the ice maker to operate for about
two hours.
6) Pour hot water 95˚F–115˚F (35˚C–45˚C) into
the ice storage bin to melt the ice that has
formed. That ice will likely be white and
frosty looking.
7) Drain pump models should have about
one-half gallon of RV antifreeze (propylene
glycol) poured into the ice storage bin
drain.
7) Clean the ice storage bin liner of mineral
scale by mixing some ice maker cleaner
and hot water, using that solution to scrub
the scale off of the liner.
IMPORTANT NOTE: DO NOT use automotive
antifreeze.
8) Replace control box cover. Turn the ice
maker OFF and unplug the unit.
8) Rinse the liner with hot water.
To use the ice maker after winterizing, recon-
nect the pump hose and water line. Repeat the
initial start-up steps outlined on page 15.
9) Sanitize the ice storage bin interior.
10)Replace the ice removed in step 2. The ice
scoop should be washed regularly; wash it
just like any other food container.
I C E M A K E R ADJUSTMENTS
There are three items that may be adjusted:
cube size, storage bin ice level and harvest
time.
Sub-Zero ice maker cleaner contains acids.
These compounds may cause burns.
If swallowed, DO NOT induce vomiting.
Give large amounts of water or milk. Call
a physician immediately. In case of skin
contact, flush with water. Keep out of the
reach of children.
IMPORTANT NOTE: Cube size and harvest
time adjustments should only be done by a
Sub-Zero authorized service center technician.
C U B E S I Z E A D J U S T M E N T
The cube size control should only be adjusted
to bring the ice cubes to the correct shape; the
overall size cannot be adjusted. Try to adjust
the cube size control when the ice maker is in
the harvest cycle, or in the first ten minutes of
the freeze cycle.

2) Remove the kickplate/grille.
3) Remove the control box cover.
4) After the next freezing cycle, the cubes
should have responded to the adjustment;
if another adjustment is required, do it early
in the freeze cycle.
4) Locate the timer shown in the illustration
below. Loosen the set screw that holds the
two halves of the timer cam together.
5) Rotate one half of the cam to open or close
the lower portion of the cam. More of an
opening equals more harvest time and less
of an opening means less harvest time.
S TO R AG E B I N L E V E L A D J U S T M E N T
When the ice maker shuts off, the ice level in
the storage bin should be even with the metal
tube inside the bin. If the ice in the storage bin
is too high or too low, turn the ice maker
control knob to adjust the ice storage bin
thermostat. Refer to the illustration below.
6) Tighten the set-screw.
7) Replace the control box cover and kickplate/
grille.
8) Reconnect the electrical power.
To lower the ice level, turn the knob counter-
clockwise. To increase the ice level, turn the
knob clockwise. Usually a 1/8 turn will be
enough for either adjustment.
