KitchenAid KUIX535HPA - 15" Automatic Ice Maker Manual

ICE MAKER MAINTENANCE AND CARE

How Your Ice Maker Works

When you first start your ice maker, the water pan will fill and the system will rinse itself before starting to make ice. The rinsing process takes about 5 minutes.

Under normal operating conditions, the ice maker will cycle at preset temperatures. The ice level sensor located in the ice storage bin will monitor the ice levels.

NOTE: If the water supply to the ice maker is turned off, be sure to set the ice maker control to Off.

Normal Sounds

Your new ice maker may make sounds that are not familiar to you. Because the sounds are new to you, you might be concerned about them. Most of the new sounds are normal. Hard surfaces such as floors, walls, and cabinets can make the sounds seem louder than they actually are. The following describes the kinds of sounds that might be new to you and what may be making them.

• You will hear a buzzing sound when the water valve opens to fill the water pan for each cycle.
• Rattling noises may come from the flow of the refrigerant or the water line. Items stored on top of the ice maker can also make noises.
• The high-efficiency compressor may make a pulsating or high-pitched sound.
• Water running over the evaporator plate may make a splashing sound.
• Water running from the evaporator plate to the water pan may make a splashing sound.
• As each cycle ends, you may hear a gurgling sound due to the refrigerant flowing in your ice maker.
• You may hear air being forced over the condenser by the condenser fan.
• During the harvest cycle, you may hear a "thud" when the ice sheet slides from the evaporator onto the cutter grid.
• When you first start the ice maker, you may hear water running continuously. The ice maker is programmed to run a rinse cycle before it begins to make ice.
• If the ice maker is connected to a water supply pressure in excess of 60 psi, you may hear a loud sound during water filling associated with the flow of water through the inlet valve. Call a licensed, qualified plumber to determine the best method to reduce the supply water pressure (50 psi is recommended).

Water Filtration System

Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.

Installing a Water Filter

1. Purchase an approved water filter.
2. Take the water filter out of its packaging and remove the cover from the O-rings. Be sure the O-rings are still in place after the cover is removed.

Quick Clean

You will need to use one 16 ounce (473 mL) bottle of approved ice maker cleaner. We recommend using the *affresh^® Ice Machine Cleaner.

Exterior Cleaning

The ice making system and the air-cooled condenser need to be cleaned regularly for the ice maker to operate at peak efficiency and to avoid premature failure of system components. See the "Ice Maker System" and the "Condenser" sections.

Exterior Surfaces

Wash the exterior surfaces and gaskets with warm water and mild soap or detergent. Wipe and dry. We recommend using a clean microfiber cloth or a soft clean cloth to polish and dry.

For ice makers with a painted or colored exterior, regular use of a good household appliance cleaner and polish will help protect the finish. Using paper towels may scratch and/or dull the clear coat of the painted door.

For ice makers with a fingerprint-resistant stainless steel exterior, do not use soap-filled scouring pads, abrasive or harsh cleaners, any cleaning product containing chlorine bleach, steel-wool pads, gritty wash cloths, or paper towels. Using these types of products may scratch and/or dull the clear coat of the fingerprint-resistant stainless steel door.

Ice Maker System

Minerals that are removed from water during the freezing cycle will eventually form a hard scaly deposit in the water system. Cleaning the system regularly helps remove the mineral scale buildup. How often you need to clean the system depends upon how hard your water is. With hard water of 15 to 20 grains/gal. (4 to 5 grains/liter), you may need to clean the system as often as every 9 months.

NOTE: Use one 16oz. (473 mL) bottle of approved ice maker cleaner. We recommend using the *affresh^® Ice Machine Cleaner.

To order, see "Accessories" on the ice maker Quick Start Guide.

1. Press the On/Off button.
2. Wait 5 to 10 minutes for the ice to fall into the storage bin. Remove all ice from the storage bin.

Electrical Requirements

Electrical Shock Hazard Plug into a grounded 3 prong outlet.
Do not remove ground prong.
Do not use an adapter.
Do not use an extension cord.
Failure to follow these instructions can result in death, fire, or electrical shock

Before you move your ice maker into its final location, it is important to make sure you have the proper electrical connection: A 115 V, 60 Hz, AC-only 15 A or 20 A electrical supply, properly grounded in accordance with the National Electrical Code and local codes and ordinances, is required.

It is recommended that a separate circuit, serving only your ice maker, be provided. Use a receptacle which cannot be turned off by a switch or pull chain.

If this product is connected to a GFCI (Ground Fault Circuit Interrupter) equipped outlet, nuisance tripping of the power supply may occur, resulting in loss of cooling. Ice quality may be affected. If nuisance tripping has occurred, and if the condition of the ice appears poor, dispose of it.

Recommended Grounding Method

The ice maker must be grounded. The ice maker is equipped with a power supply cord having a 3-prong grounding plug. The cord must be plugged into a mating, 3-prong, grounding-type wall receptacle, grounded in accordance with the National Electrical Code and local codes and ordinances. If a mating wall receptacle is not available, it is the personal responsibility of the customer to have a properly grounded, 3-prong wall receptacle installed by a qualified electrician.

Drain Connection Requirements

Gravity Drain System

Connect the ice maker drain to your drain in accordance with all state and local codes and ordinances. If the ice maker is provided with a gravity drain system, follow these guidelines when installing drain lines. This will help keep water from flowing back into the ice maker storage bin and potentially flowing onto the floor, causing water damage.

• Drain lines must have a minimum of 5/8" (15.88 mm) I.D. (inside diameter).
• Drain lines must have a 1" drop per 48" (2.54 cm drop per 122 cm) of run or 1/4" drop per 12" (6.35 mm per 30.48 cm) of run and must not have low points where water can settle.
• The floor drains must be large enough to accommodate drainage from all drains.
• The ideal installation has a standpipe with a 1 1/2" (3.81 cm) to 2" (5.08 cm) PVC drain reducer installed directly below the outlet of the drain tube as shown. You must maintain a 1" (2.54 cm) air gap between the drain hose and the standpipe.
• Do not connect the outlet end of the drain tube to a closed pipe system to keep drain water from backing up into the ice maker.

A drain pump is necessary when a floor drain is not available. A Drain Pump kit is available for purchase. See Quick Start Guide for ordering information.

Water Supply Requirements

Check that the water supply lines are insulated against freezing conditions. Ice formations in the supply lines can increase water pressure and damage your ice maker or home. Damage from frozen supply lines is not covered by the warranty. A cold water supply with water pressure of between 30 and 120 psi (207 and 827 kPa) is required to operate the ice maker. If you have questions about your water pressure, call a licensed, qualified plumber.

Reverse Osmosis Water Supply

• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.
• A reverse osmosis water filtration system is not recommended for ice makers that have a drain pump installed.
• For gravity drain systems only.
• Connect to portable water only.
• The pressure of the water supply coming out of a reverse osmosis system going to the water inlet valve of the ice maker needs to be between 30 and 120 psi (207 and 827 kPa).

If a reverse osmosis water filtration system is connected to your cold water supply, the water pressure to the reverse osmosis system needs to be a minimum of 40 to 60 psi (276 to 414 kPa).

NOTE: The reverse osmosis system must provide 1 gal. (3.8 L) of water per hour to the ice maker for proper ice maker operation. If a reverse osmosis system is desired, only a whole-house-capacity reverse osmosis system, capable of maintaining the steady water supply required by the ice maker, is recommended. Faucetcapacity reverse osmosis systems are not able to maintain the steady water supply required by the ice maker.

If the water pressure to the reverse osmosis system is less than 40 to 60 psi (276 to 414 kPa):

• Check to see whether the sediment filter in the reverse osmosis system is blocked. Replace the filter if necessary.
• Allow the storage tank on the reverse osmosis system to refill after heavy usage.

If you have questions about your water pressure, call a licensed, qualified plumber.

Connect Water Supply

Read all directions before you begin.

• Connect to potable water only.
• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.
• Plumbing shall be installed in accordance with the International Plumbing Code and any local codes and ordinances.
• Use copper tubing or supply line, and check for leaks.
• Install tubing only in areas where temperatures will remain above freezing.

Tools Needed:

Gather the required tools and parts before starting installation.

• Flat-blade screwdriver
• 7/16" and 1/2" open-end wrenches or two adjustable wrenches 1/4" nut driver

NOTE: Do not use a piercing-type or 3/16" (4.76 mm) saddle valve which reduces water flow and clogs more easily.

Connecting the Water Line

1. Turn off main water supply. Turn on nearest faucet long enough to clear line of water.
2. Using a 1/2" copper supply line with a quarter-turn shutoff valve or the equivalent, connect the ice maker as shown. NOTE: To allow sufficient water flow to the ice maker, a minimum 1/2" diameter home supply line is recommended.

Leveling and Securing

It is important for the ice maker to be level in order to work properly. Depending upon where you install the ice maker, you may need to make several adjustments to level it. You may also use the leveling legs to lower the height of the ice maker for under counter installations.

Tools Needed:
Gather the required tools and parts before starting installation.

• Level
• Adjustable wrench

NOTE: It is easier to adjust the leveling legs if you have another person to assist you.

Excessive Weight Hazard
Use two or more people to move and install or uninstall appliance.
Failure to do so can result in back or other injury.

1. Move the ice maker to its final location. Be sure to cover the floor with cardboard or hardboard to avoid damaging it. NOTE: If this is a built-in installation, move the ice maker as close as possible to the final location.

For standard models:

2. Place the level on top of the ice maker to see whether the ice maker is level from front to back and side to side.
3. Push up on the top front of the ice maker, and then locate the leveling screws that are on the bottom front of the ice maker.
4. Using an adjustable wrench, change the height of the legs as follows:
   • Turn the leveling leg to the right to lower that side of the ice maker.
   • Turn the leveling leg to the left to raise that side of the ice maker.
     NOTE: The ice maker should not wobble. Use shims to add stability when needed.
     
5. Push up on the top rear of the ice maker and locate the leveling legs that are on the bottom rear of the ice maker.
6. Follow the instructions in step 4 to change the height of the legs.
7. Use the level to recheck the ice maker to see that it is even from front to back and side to side. If the ice maker is not level, repeat steps 2 to 5. If the ice maker is level, go to the "Connect Water Supply" section.
   For cabinet models:
   
   Crush Hazard
   Articulated hinges are self closing and many pinch points exist prior to cabinet installation.
   Do not remove hinge covers until product is ready to be installed.
   Failure to follow these instructions can result in crush, cut, or pinch injuries.
8. Remove the screws attaching top and bottom hinge covers using an 3/16ʺ hex driver.
