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. 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 50F (10C), and the maximum is 100F (40C). W AT 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 40F (5C), and the maximum is 100F (40C). 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. 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 quickly. This occurs because impurities cause 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 waters aggressiveness. Deionized water is not recommended. 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.

AREA REQUIREMENTS 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 78. The illustrations below provide overall dimensions for Models 315I and 315IP. 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 78. 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: The floor under the ice maker must be at the same level as the surrounding finished floor. 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.
Any finished flooring should be protected with appropriate material to avoid any damage from moving the unit.

ELECTRICAL R E Q U I R E M E N T S
PLUMBING R E Q U I R E M E N T S 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 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 78. 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 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 illustrations on pages 78. IMPORTANT NOTE: A ground fault circuit interrupter (GFCI) is not recommended and may cause interruption of operation.

I M P O RTA N T N OT E

You must follow all National Electrical Code regulations. In addition, be aware of local codes and ordinances when installing your services.
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.
MODEL 315I G R AV I T Y D R A I N
The drain and inlet water tubes must be plumbed before connecting to the ice maker. Refer to the illustrations below. All horizontal runs of drain lines must have a 1/4" (6) per 12" (305) fall. An air gap will likely be required between the ice maker drain tube and the 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. 5) If the electrical outlet for the ice maker is behind the unit, plug in the unit. 6) Position the unit in the installation opening. 7) Cut the water inlet line to the required length. 8) Flush the water line. Place the flare nut on the water line and flare the end of the copper tube.

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.

IMPORTANT NOTE: Turn on the water supply and check all fittings for leaks. Make sure the electrical harness is attached to the solenoid. Let your customer know that the ice maker will not fill with water immediately and that the first batch of ice produced should be discarded. Allow 24 to 36 hours for proper ice production. LEVELING Level the Model 315I(P) by turning the leveling legs counterclockwise to raise or clockwise to lower. To assist you in adjusting the front leveling legs up or down, use a standard screwdriver blade and place it in the front leveling leg to turn. SECURE THE ICE MAKER To secure the ice maker, install two #8 x 1/2" flat head screws through each hinge. Refer to the illustration below.
K I C K P L AT E / G R I L L E I N S TA L L AT I O N Once the ice maker is secured, you can install the kickplate/grille. As shown in the illustration below, there is some adjustment to the mounting assembly so this decorative piece can fit flush with the surrounding area.
DO NOT cover the kickplate/grille area.
The unit must be allowed to have ventilation through these fins. The door panel may hang in front of the fins, but a decorative kickplate/ grille must not cover the fins. The kickplate/grille can be painted another color, if you choose. Follow these easy steps: Rough up surface to be painted with fine grit sandpaper. Wipe with alcohol to ensure it is clean and dry. Use an appliance or industrial grade, oil base, high gloss enamel paint.

IMPORTANT NOTE: To ensure a safe and proper installation, the following checklist should be completed by the installer to ensure that no part of the installation has been overlooked. Any questions or problems about the installation should be directed to your Sub-Zero dealer or Sub-Zero Customer Service at 800-222-7820. You can also visit our website at subzero.com. Is the unit operating? If not, is the unit plugged in? Check to see if the unit is operating before you install. Has the unit been properly uncrated, and have all packing materials and tape been removed from inside the unit? Have the installation instructions been followed? Has the unit been leveled? Is the kickplate/grille installed? If applicable, is the door panel installed properly? Does the customer understand the units operation? Have any installation or service problems been noted on the product registration card? Instruct the owner to register the product.

ICE CUBES 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. 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 its 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. The Model 315I(P) will continue to operate until ice builds up high enough to contact thermostat 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. RUN TIME 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 2436 hours to refill.

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. 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. FREEZE CYCLE 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 enough, the ice makers 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.

Failure to clean the condenser could result in temperature loss or mechanical failure or damage.

I C E M A K E R CLEANING

I C E M A K E R MAINTENANCE
CLEANING THE ICE MAKING SYSTEM 1) Open the door and turn the ice maker control knob to OFF. Refer to the illustration on page 19 for location of the control knob. ICE MAKER CLEANER
Sub-Zero ice maker cleaner (8 oz. bottle) is available from your Sub-Zero dealer. Ask for part #19034306.
WINTERIZING 1) Clean the ice making system. 2) Turn off the water supply. 3) Drain the water reservoir. Remove the pump hose. 4) Disconnect the incoming water line at the inlet water valve. 5) Remove control box cover and turn the timer into the harvest cycle. 6) With the ice maker operating, blow air through the inlet water valve; a tire pump could do the job. 7) Drain pump models should have about one-half gallon of RV antifreeze (propylene glycol) poured into the ice storage bin drain. IMPORTANT NOTE: DO NOT use automotive antifreeze. 8) Replace control box cover. Turn the ice maker OFF and unplug the unit. To use the ice maker after winterizing, reconnect the pump hose and water line. Repeat the initial start-up steps outlined on page 15.
2) Scoop out all of the ice; either discard it or save it in a ice chest or cooler. 3) Pour four ounces of Sub-Zero ice maker cleaner into the ice maker reservoir (see side note). 4) Turn the ice maker control to ON. 5) Allow the ice maker to operate for about two hours. 6) Pour hot water 95F115F (35C45C) into the ice storage bin to melt the ice that has formed. That ice will likely be white and frosty looking. 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. 8) Rinse the liner with hot water. 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. IMPORTANT NOTE: Cube size and harvest time adjustments should only be done by a Sub-Zero authorized service center technician. CUBE SIZE ADJUSTMENT 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.
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.
1) Open the door and remove the control box cover. 2) Locate the cube size adjustment screw shown in the illustration below. To make fuller cubes, turn the screw clockwise about 1/4 turn. This will make the freezing cycle longer. 3) To shorten the freezing cycle and make cubes that are not as full, turn the adjustment screw 1/4 turn counterclockwise. 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. 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. To lower the ice level, turn the knob counterclockwise. To increase the ice level, turn the knob clockwise. Usually a 1/8 turn will be enough for either adjustment.
H A RV E S T T I M E A D J U S T M E N T The amount of harvest time may be adjusted. It is preset from the factory at about three minutes, which should be adequate to release all cubes and fill the reservoir. If the timer needs to be adjusted, follow these steps: 1) Unplug the ice maker or disconnect the electrical power. 2) Remove the kickplate/grille. 3) Remove the control box cover. 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. 6) Tighten the set-screw. 7) Replace the control box cover and kickplate/ grille. 8) Reconnect the electrical power.
