June 2001 Page 2 FOR THE INSTALLER Location: Prior consideration for the location shall include: CSE60 The front panel MUST remain unobstructed. Do not block with any type of door or curtain. If the unit is built in, it will pull air in from the right side of the front panel, and exhaust it out the left side of the front panel. If the left side of the machine is left open, warm air will be discharged from the left side panel. ·Indoors, with a minimum room temperature of ·Water temperature to the machine should be ·Service Access. Allow enough space at the back of the cabinet for the utilities to be connected. Allow enough space for the machine to be pulled out from its installed location. Do not build a floor in front of the machine that would prevent its removal. between 400F. and 1000F. 500F. and a maximum room temperature of 1000F. ·Air circulation: IF BUILT IN, THIS SIDE SHOULD BE TIGHT AGAINST THE CABINET TO PREVENT AIR RECIRCULATION COOL AIR INTAKE WARM AIR DISCHARGE June 2001 Page 3 CSE60 FOR THE PLUMBER Water supply and drain connections. 1. The recommended water supply line is a 3/8" o.d. copper tube, the water pressure must have a minimum incoming pressure of 20 psig. 2. Connect the tubing to the 3/4" GAS / BSPP thread water inlet fitting at the back of the ice maker. An adapter is available, the part numbers are: F733219-03 and F640134-00. 3. Install a shut off valve in the incoming water line near the ice maker so that the water can be shut off for service. 4. Connect a gravity drain line to the drain connection at the ice maker. A minimum slope of 1/4" fall per foot of horizontal run is recommended. Install the drains per the local codes. POWER SUPPLY LEVEL THE UNIT Note: Although soft, easily kinked vinyl tubing is not recommended for a drain, a short length of ¾" ID vinyl tubing is required to connect a rigid drain tube to the 20 mm (25/32") fitting on the back of the machine. A vent is recommended on the highest point of the drain tube, and the drain tubing must be rigid pipe. Do NOT use flexible tubing for the entire drain system. A short section of ¾ " ID flexible tubing and suitable hose clamps may be used to interconnect a rigid drain system to the .78" OD (20 mm) plastic drain fitting on the ice machine. WATER SUPPLY SHUT OFF POWER CORD WATER FILTER (FIELD SUPPLIED) DRAIN ADAPTER (FIELD SUPPLIED) ELECTRICAL 1. Locate the nameplate on the lower rear panel and check that the location source voltage and capacity are correct for this unit. The unit is equipped with a grounded plug connection. Under no circumstances must the ground post be altered or removed. Extension cords are not permitted. Be certain that the ice maker is connected to its own electrical circuit and is individually fused. The maximum allowable voltage variation should not exceed ten percent of the nameplate rating. All external wiring should conform to the National, State, and local electrical code requirements. Usually an electrical permit and the services of a licensed electrician will be required to install the receptacle. December 2005 Page 4 INSTALLATION FINAL CHECK 1. Is the Cabinet level? 2. Have all the electrical and piping connections been made? 3. Has the voltage been tested and checked against the nameplate rating? 4. Is the unit plugged into a separate electrical circuit? 5. Is the water supply line shut off valve installed and is the water turned on? CSE60 6. Have the bin interior, and the cabinet exterior been wiped clean? 7. Are all internal parts in place, including the spray platform and curtain? 8. Have the internal refrigerant lines been checked for rubbing and chaffing? 9. Has the machine been installed where it is indoors, in a controlled environment, with adequate air circulation around the machine, and where it can be serviced? POWER? LEVEL? DRAINS? WATER? June 2001 Page 5 CSE60 INITIAL START UP 1. Open water supply valve. 2. Move electrical breaker or switch to the on position. 3. Remove front panel. 4. Check the cube size control shaft, it should be in a preset cube size position. If not, turn it clockwise until the unit comes on. Note: cube size adjustments may be required. Start with the shaft in the "mid" position. 5. The machine will go thru a "dry" cycle, this will take about 10 minutes. Then the water fill and harvest cycle will begin. 6. Observe the water fill cycle: If the cubes are overfilled, adjust the machine to make smaller ice cubes by turning the cube size control counter-clockwise. In both cases, the next cycle of cubes harvested must be observed, and further corrections may be needed. If the ice cubes are cloudy, an extreme water condition may exist. Confirm that they are cloudy by placing them in a glass of cold water. If, in the water, they remain cloudy, you may want to have the water tested by a water treatment specialist. If the ice cubes are cloudy only on the bottom or in the center, the machine may be running out of water before the end of the freezing cycle. 10. Test the bin full shut off. To test this, hold some ice on the bin thermostat bracket (the stainless steel tube on the left side of the ice storage bin). The ice maker should stop within a few minutes of having ice on that tube. 11. Fill out the Warranty Registration and Customer Evaluation form, and mail it to Scotsman. 12. Make sure the user understands the operation and maintenance requirements for the ice maker. Leave the service manual and the name of the local Scotsman service agency with the user. ·The water inlet valve opens. ·Incoming water flows from the valve through ·Water flows around the inverted ice cube ·The reservoir begins to fill up with water. ·Water continues to enter the machine and cups and drains through holes into the reservoir. the tubing to the top of the ice maker. overflows a standpipe in the reservoir and down the drain. This will take about 3 minutes. After that the freeze cycle will begin. 7. Check the operation of the freezing cycle: ·Compressor is running. ·Water pump is spraying water through the begins, the water gets very cold, and ice begins to form in the cube molds. 8. Check that the plastic curtain assembly hangs down evenly in the opening and that no large streams of water are passing through. Note: Some water will drip from the reservoir as the machine runs. This is normal. 9. After about 20 minutes the machine will begin to release the ice, this is called the harvest cycle. Observe the first cube harvest: ·Ice making spray nozzles. ·Check the size of the ice cubes. Note: The normal size of the ice cube has a 1/4" depression in the wide end. If the cubes are not filled out, adjust the machine to make larger ice cubes by turning the cube size control shaft clockwise. June 2001 Page 6 HOW IT WORKS: COMPONENT DESCRIPTION Cube Size Control The cube size control is located in front of the control box, behind the front panel. The sensing capillary tube of the cube size control is routed out of the control box into its bulb holder on the evaporator coil. It is a reverse acting temperature control with double throw contacts. Turning its knob all the way counterclockwise also shuts off the ice maker. The control determines the length of the freezing cycle and correspondingly the size of the cube. A lower setting will produce a smaller cube, and a higher setting will make a larger cube. The cube size control changes its contacts when the evaporator reaches its preset temperature, starting the harvest cycle. When the sensing tube of the cube size control reaches the high preset temperature, the contacts change again, restarting the freeze cycle. Compressor Toggle Switch. The compressor toggle switch is located on the side of the control box. When moved to the ON position, it makes a circuit to the compressor. When moved to the OFF position, the other components will still operate. High Temperature Cut Out This control senses the temperature of the discharge line and will open to stop the operation of the ice machine should the discharge temperature exceed the preset maximum (175oF). After it cools to 140oF. it must then be manually reset to restart the machine by pushing the button at the front of the control box. Water Pump The water pump operates during the freezing cycle only, pumping water through the spray nozzles into the inverted spray cups. Inlet Water Solenoid Valve The water solenoid valve, located in the back panel of the unit, is energized only during the harvest or cleaning cycles. When energized it allows a metered amount of water to flow into the machine (.21 g.p.m.) This water flows to the top of the evaporator and then down into the reservoir.

The thermostat sensing tube is located in the ice storage bin on the left side wall where is automatical ...
