INSTALLATION INFORMATION
ELECTRICAL SUPPLY REQUIREMENTS
WARNING
Electrical Shock Hazard
• A 115 Volt, 60 Hz, AC only 15 ampere 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 the ice maker, be provided. Use a receptacle which cannot be turned off by a switch or pull chain.
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 the ice maker into its final location, it is important to make sure you have the proper electrical connection:
Recommended Grounding Method
For personal safety, this appliance must be grounded. This appliance is equipped with a power supply cord having a 3-prong grounding plug. To minimize possible shock hazard, 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.

WATER SUPPLY AND DRAIN CONNECTIONS
CAUTION: To prevent damage to the freezer
mechanism, do not operate this ice maker when the water supply is OFF, or if the pres­sure is below 10 PSIG (0.7 bar), the recom­mended water pressure. Stop the ice maker until proper water pressure is resumed.
• The water supply inlet is 1/2-14 NPT and must only be connected to a potable water supply.
• A water supply line shut-off valve and drain valve must be installed.
• Water supply pressure should be a minimum of 10 PSIG (0.7 bar), and a maximum of 113 PSIG (7.5 bar). If the pressure exceeds 113 PSIG (7.5 bar), use a pressure reducing valve.
Ice Maker
• The drain outlet hose is 5/8 (16mm) I.D. and internally connected with a 2/3 (17mm) O.D. drain outlet.
• The drain must be 1/4 fall-per-foot (2 cm fall-per-meter) on horizontal runs for opti­mum flow.
• Keep a 2 vertical inch (5 vertical cm) air gap or more between the drain pipe end and the sink.
• The drain pipe must be used to prevent a backflow into the storage bin.
• This ice maker should be installed in accor­dance with applicable national, state, and local regulations.

THEORY OF OPERATION
THE CONTROLS
ICE MAKING CONTROL
The freeze and harvest cycles are controlled by a thermistor and an electronic control.
The electronic controller uses a thermistor that is attached to the top of the evaporator to monitor the evaporator temperature. When the thermistor signals 28°F (–2°C), the control begins to count down 10 minutes. The elec­tronic control then switches the contacts of relays X1 and X2, which stops the pump and fan motors, and engerizes the hot gas and water valves. This completes the freeze cycle, and starts the harvest cycle.
HARVEST CONTROL
The ice cubes formed inside the ice making cells are released by hot gas warming the evaporator. When a small portion of the ice melts on the ice making cells interior, the ice drops down the ice guide into the storage bin.
When the evaporator is warmed further (to approximately 45°F / 7°C), the thermistor sen­ses the temperature rise, and the electronic controller begins to count down 50 seconds. The controller then switches the contacts of the relays, which starts the pump and fan motors, and de-energizes the hot gas and water valves. This completes the harvest cycle, and starts the freeze cycle. The harvest and freeze cycles will continue until the bin is full of ice and the bin thermostat is satisfied.
At low temperature conditions where the har­vest cycle exceeds 3 minutes, the water valve will de-energize after 3 minutes.
At the initial start, or after a power failure, the ice maker will begin in the harvest cycle, be­cause the compressor is under a “no load” condition (hot gas valve is energized). During this time, any ice that is present on the evapo­rator will be removed.
In the initial cycle at startup, or after shutdown for bin control, water is supplied for 80 sec­onds. The water valve de-energizes approxi­mately 30 seconds after the freeze cycle starts.
NO ADJUSTMENT
The thermistor and electronic control are fac­tory adjusted to produce constant ice all year, and are not affected by changes in the ambient and water temperatures. No adjustment is re­quired for any frequency 50/60Hz or ambient temperature from 45 to 100°F.
No Adjustment. Controls Are Sealed. If Seals Are Broken,
Replace Control.

COMPONENT TESTING
Before testing any of the components, perform the following checks:
• Control failure can be the result of corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary through­out test procedures.
• All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohms­per-volt DC, or greater.
Electrical Shock Hazard Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock.
• Check all connections before replacing com­ponents, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.
• Resistance checks must be made with power cord unplugged from outlet, and with wiring harness or connectors disconnected.
WARNING

TECH TIPS
CLEANING THE ICE MAKER
WARNING
Electrical Shock Hazard
Disconnect power before servicing.
6. Push in on each of the ice guards and unhook them from the hanger rod.
ICE GUARDS
Replace all parts and panels before operating.
Failure to do so can result in death or electrical shock.
NOTES:
• KitchenAid recommends cleaning the ice maker at least once a year. More frequent cleaning may be required in areas that con­tain heavy amounts of minerals in the water supply.
• To prevent damage to the ice maker, do not use ammonia or abrasive-type cleaners. Use only LIME-A-WAY® Cleaner (see step 9 on page 8-2).
• Always wear rubber gloves when handling cleaning solutions.
ROUTINE CLEANING
1. Set the master switch to OFF and turn off
the water supply to the ice maker.
Hanger Rod
7. Squeeze the locking tabs on the suction tube to release them and disconnect the tube from the water tank. Drain the water from the tank.
2. Unplug the ice maker or disconnect power.
3. Open the ice maker door.
4. Remove the ice from the storage bin.
5. Remove the ice scoop and its holder.

8. Pull out on the left and right locking tabs, and pull the reservoir out of the unit. Empty the reservoir, and then reinstall it.
9. Dilute approximately 5 oz. (148 ml) of LIME-A-WAY® cleaner with 1 gallon (3.8 lit.) of water.
10. Slowly pour the cleaning solution into the reservoir.
CLEANING THE SPRAY ASSEMBLY
NOTE: If the ice maker spray assembly re­quires further cleaning, perform the following steps.
1. Lift the ice chute off the front and rear frame pipes and remove the chute from the unit.

11. Position the master switch to the WASH position.
12. After circulating the cleaning solution for 30 minutes, position the master switch to OFF.
13. Remove the reservoir and drain it, then reinstall it in the unit.
14. Turn on the water to the ice maker.
15. Position the master switch to the WASH position and allow the water to circulate for 5 minutes.
16. Position the master switch to OFF and immediately back to WASH and allow the system to rinse.
17. Repeat steps 15 and 16 three times to completely rinse the system.

5. Dilute approximately 5 oz. (148 ml) of LIME-A-WAY® cleaner with 1 gallon (3.8 lit.) of water.
6. Clean the caps and spray assembly. If the spray nozzles are clogged, use a wire to remove the clog, or use a suitable wire brush.
7. Thoroughly rinse the spray assembly with clean water.
8. Reinstall the two caps on the spray nozzle assembly.
9. Reassemble the ice making components.
NOTE: During normal operation, if ice is stick­ing to the evaporator plate, check the “weep” holes in the top of the plate. The holes must be open to allow ice to drop.
