INSTALLATION INFORMATION ELECTRICAL SUPPLY REQUIREMENTS • 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. WARNING Electrical Shock Hazard Recommended Grounding Method For personal safety, this appliance must be grounded.
WATER SUPPLY AND DRAIN CONNECTIONS 8. Use 1/4″ (6.35 mm) O.D. copper tubing for the cold water supply and: a) Measure from the connection at the back of the ice maker to the cold water pipe. b) Add an extra 36″ (91.4 cm) to ensure that you have the proper length. Make sure both ends of the copper tubing are cut square. c) Slip a compression sleeve and compression nut over the ends of the copper tubing.
CONNECTING THE DRAIN 11. Thread the nut onto the coupling at the end of the copper tubing. Tighten the nut by hand. Then tighten it with a wrench two more turns. Do not overtighten. 1. Line to ice maker 2. Nut (purchased) Gravity Drain System Connect the ice maker drain so that it is in accordance with all state and local codes and ordinances. If the ice maker is provided with a gravity drain system, use the following guidelines when installing the drain lines.
After ensuring that the drain system is adequate, use the following steps to properly place the ice maker: 1. Plug in the ice maker or reconnect power. 2. Recheck the ice maker and make sure that it is level. 3. Push the ice maker into position so that the drain tube is positioned over the PVC drain reducer. 4. If it is required by the local sanitation code, seal the cabinet to the floor with an approved caulking compound after all water and electrical connections have been made.
THEORY OF OPERATION OPERATING SYSTEMS There are three operating systems in the ice maker: • Refrigeration System • Water System • Electrical System There are two very important additions to the refrigeration system in the ice maker: the Hot Gas Valve, and the Condenser Accumulator Tube. The components operate as follows: • Hot Gas Valve - Allows high pressure refrigerant gas to bypass the condenser and flow through the condenser accumulator tube.
WATER SYSTEM A water softener, or polyphosphate feeder, will not cure all of the problems associated with hard water, but they can be used to reduce scale buildup in the ice maker. NOTE: Some polyphosphate feeders will cause a slime buildup in the water system when the water supply has a low mineral content. The ice maker’s water system is shown below.
ELECTRICAL SYSTEM The ice maker’s electrical system provides power for the refrigeration and water systems, and controls the operational cycling.
OPERATIONAL CYCLES There are three main operational cycles for the ice maker (more detailed operation is found in the flow chart on page 6-5): • Ice Making • Harvest • Diagnostics/Clean During the Ice Making cycle, some of the hot gas that is in the condenser accumulating tube, condenses to a liquid, and remains in the accumulating tube.
HARVEST CYCLE The electronic control board controls the various components and systems in the ice maker for each of the Ice Making and Harvest cycles. When the ice maker’s service control switch is in the “On” position, and the bin is not full of ice, the evaporator thermistor determines whether the unit will be in the Ice Making, or the Harvest cycle. If the thermistor is unplugged from the control board, the unit will cycle using maximum freeze and harvest times.
NEW ICE MAKER CONTROL BOARD (#6100499) NOTE: Due to a quality improvement, the new control board will replace the older design (#2185947). If you are replacing control board #2185947, please read the improvements listed below. If you are replacing control board #6100499, you may disregard the following information. There are no differences in mounting or wiring the new control board. Improvements were made to support low voltage applications.
MODELS WITH INTERNAL DRAIN PUMPS The power cord on the internal drain pump is connected to a 120 VAC wall outlet. The ice maker is then connected to the 120 VAC outlet on the drain pump. If the drain pump fails, or if the drain becomes blocked, power is shut off to the 120 VAC outlet on the drain pump. When the unit is first plugged in, the drain pump will run for 20 seconds. The power can be disconnected and reconnected to verify that the pump is operating properly.
