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

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

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

The floor under the

surrounding finished floor.

MPORTANT 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

t does not open while transporting the unit.

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.

(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.

Place the ice maker in front of the installation opening. Adjust leveling legs to the approximate height.

Remove the door (with hinges), control knob, control panel, access panel and lower face plate.

Route the water inlet line (1/4" OD copper tube) from the wall through the ice maker to the front.

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.

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.
