The refrigeration connections can be made out the top panel or out the back. The electrical power cord and the water inlet line can also be routed through either of those areas. The drain may be routed out the back at any position left to right; it may also be routed to either side. The ice sensors, used for determining if the bin is full or not, are located in housings that extend below the bottom of the unit. As ice is made, it will build up in the bin or dispenser until the top of the ice pile is between the sensors. At that point, about 3” below the bottom of the cabinet, the ice machine will shut off. This ice level maximizes ice storage without overfilling the bin or dispenser. Water Pure water does not exist. All water supplies contain some amounts of impurities, although potable water is, by definition, fit for human consumption. Because the contents of the water to an ice machine directly impact its performance, consideration should be given to improving the water’s quality. There are two ways water can contain impurities: in suspension or in solution. Suspended solids can be filtered out of the water. In solution or dissolved solids must be diluted or treated. Water filters are recommended to remove the suspended solids. Some filters or filter systems have treatment chemicals in them for treating the suspended solids. This ice machine has an adjustment for the amount of water rinsed or purged. Water use adjustments are customer convenience adjustments; they are not factory defects and are not covered by warranty. June 2002 Page 7 Eclipseä 600, 800, 1000 Create the System Plan the installation. The system consists of four parts: the ice making section, the compressor package, the interconnecting tubing and the remote condenser. Of these, the biggest variable is the interconnecting tubing. Interconnecting wires: An interconnecting wire harness is included with the CP unit. One end plugs into the ice making section and the other into the compressor package. The system will NOT operate without this harness. Tubing: The tubing consists of three pre-charged, insulated and sealed soft copper tubes. They each contain a small holding charge of R-404A. One tube, the liquid line, is 3/8” OD. The discharge tube is ½” OD and the suction tube is ¾” OD. A site inspection will determine what length of tubing is required for the installation. Exposed tubing: Minimize the amount of tubing exposed outdoors. Excess tubing must be either shortened at the job site (recovering the holding charge, purging with nitrogen when brazing and evacuating to 50 microns) or coiled up inside the building. connecting to an approved condenser coil. Installations with greater than 20 feet of vertical lift between ice machine and the compressor require a suction line trap. The suction line requires careful handling and large radius bends to prevent kinking. Roof mounting: To make installation easier the compressor and condenser are designed to be assembled together on the roof. Some installations will require the use of a hoist to lift the components to the roof. Pad mounting: The compressor and condenser may be located below the ice making section, up to a limit of 15 feet. Distance from unit: Limited to the length of the available pre-charged tubing. Confirm Component Availability: · CME686 or CME810 · CP686 or CP886 or CP1086 · ERC680 or ERC1086 or ER2C6810 unless Note: Only these condensers may be used. They do NOT contain a headmaster valve. That valve is in the Compressor Package. Do NOT use any other Scotsman condenser. Do NOT use these condensers on any other Scotsman remote product. · Interconnecting tubing kit Note: Check tubing integrity before assembly by attaching a refrigeration compound gauge onto one of each tube’s schrader valves. If there is pressure, the tube is OK, if not it should be checked for damage and leaks. · Bin or dispenser adapter Elevation: CP unit limited to 35 feet above the ice making section. Compressor package: Electrical power must be supplied to the compressor package. The remote condenser fan motor takes its power from the compressor package. Ice making section location and attachment: The unique footprint of the CME686 and CME810 require adapter kits to allow placement on dispensers and bins. The remote tubing connections must be made from the right side of the machine, and connections should not be made until the machine is nearly in its final installed position. The 115/60 Hz ice making section is cord connected and requires an outlet within 6 feet of the installation. April 2002 Page 8 Eclipseä 600, 800, 1000 System Examples The Eclipse system can be installed on a bin or dispenser. The CP unit can be installed on either a single circuit condenser, a two circuit condenser or onto a coil in a separate rack condenser. Separate coils must be: · Scotsman approved · The correct size and capacity · New or not have been part of a system that used mineral oil. Single Circuit System Single Circuit System on ABS Dispenser April 2002 Page 9 Eclipseä 600, 800, 1000 System Examples Single circuit systems use a single circuit condenser and one CP unit. Two circuit systems use a condenser with two circuits with a CP unit at each end. IMS on ABS Dispenser, CP Unit Connected to Approved Rack System April 2002 Page 10 Two Circuit System Eclipseä 600, 800, 1000 Place Remote System Roof preparation Roof Piercing: Most installations of this system will place the compressor package and condenser on the roof of a building. The roof must be physically stout enough to accept the load of the equipment and the roofing material must be prepared to prevent water leaks. The roof (or wall) must have a passage large enough for the three pre-charged, pre-bent tubes and the control wire to pass through. The minimum recommended size is 4” ID. In most areas the power supply may also pass through the same passage. If there isn’t a passage one must be created. In most cases this must be done by a licensed and bonded roofer in order to maintain the roof’s integrity. Follow local codes for the placement and attachment of the equipment. Location The condensing unit assembly requires unobstructed air flow to operate efficiently. A four foot space between each intake side and a wall or other cabinet is recommended. Do not place where it will pick up hot discharged air from an air conditioner or other refrigeration system condensing unit. Space must also be reserved for service on the compressor package. If using the ER2C6810 condenser, save space for the second CP unit to be attached to the other end of the condenser. Suggestions: Hoist the compressor package and condenser to the roof in separate loads. Note: In most cases a mechanical lift, boom truck or crane will be required to hoist the condensing unit components. Assemble the compressor package to the condenser and mount both to either roof rails or pressure treated 4 x 4s. Orient the assembled unit so that the unit’s mounts are parallel to the pitch of the roof to allow water to drain freely. Do NOT place the unit directly onto roof rock. IMS Shown on Ice Dispenser April 2002 Page 11 Eclipseä 600, 800, 1000 System Location Line Routing: Limitations: Distance: Limited to the maximum length of a single pre-charged tubing kit, 75 feet. Condensing Unit Elevation over Ice Making Section: 35 feet. · Allowed: One rise after a drop. · Allowed: One drop after a rise. · Not Allowed: More than one rise after a drop · Not Allowed: More than one drop after a rise. Note: Elevations greater than 20 feet require installation of a suction line trap at the 20 foot mark. Ice Making Section Elevation over Condensing Unit: 15 feet.

Liquid Select the correct end to send to the roof. The method or technique used to route the tube is left to the installer. However, in many cases it is easier to position the tubing inside the building first, then feed the outside portion through the tubing passage (pitch pot). Installation of tubing will be easier if the suction line is run first, followed by the liquid and vapor lines. Use of two persons is suggested to prevent kinking of the tubing, long runs may require three people. · Allow enough tubing to make large radius bends Vapor from the roof passage to the compressor unit. Do NOT leave excess tubing on the roof. · If a trap must be installed, the suction line tubing must be cut apart to install it. · Identify the ice machine end of the tubing. Each tube has one end formed to route through the hole in the unit’s top. Suction · Tape the ends of the vapor and liquid line tubes together along with the interconnecting wire. Extend the end of the interconnecting wire about 2 feet beyond the end of the precharged tubes and then tape it back onto the tubes. · If the tubing is to be routed out the back, use the ends with the single 90 degree bends. · Route the three tubes and the wire from the roof, or other entrance, to the ice making section’s planned position. Avoid uncoiling and recoiling the tubing, as that can lead to kinks. Liquid · Support long runs of tubing with hangers. · Repair any tears in the tubing insulation, especially those on the suction line that are inside the building. Shortening Tubing Vapor The precharged tubing kits are available in a variety of lengths, they should only be shortened if absolutely necessary. To Shorten Tubes: 1. Recover the 3 ounce R-404A holding charge from each tube. Suction 2. Cut out the required length of tubing, do not cut the tubing right at the quick connects. Note: Units mounted flush against the wall require refrigerant connections out the top, water supply in from the top, power supply routed through the top and drain routed to a side. 3. Attach nitrogen bottle to one quick connect and a hose with a depressor to the other end, purge nitrogen through each tube while brazing. 4. Remove nitrogen, evacuate to 200 microns. Note: If tubes are connected to the IMS, evacuate the vapor & suction lines to get the entire system.

The drain fitting is adaptable to drain connections to the left, right and back. Determine how the water supply and drain will be connected to the ice making section. The unit is shipped ready to drain left. The drain hose to drain right is in a bag packed near the water pump. · If access is available behind the unit, route the drain and water supply in from the back. · If the unit is to be flush mounted to the back of the dispenser and tight against the wall, the water supply must be routed from the top right corner and the drain out either the left or right back corners. In some tight situations it will be necessary to assemble the ice making section to the dispenser or bin and install the water and drain connections before placing the system in its installed position. A loop of water supply tubing will allow movement of the system. In other tight situations the unit should have its water and drain tubing connected and stubbed out before placing on the dispenser or bin.

Continue tightening the swivel nut until it bottoms out or a very definite increase in resistance is felt (no threads should be showing). Do NOT overtighten. Initial Connections 1. Remove the protector caps and plugs. Wipe the seats and threaded surfaces with a clean cloth to remove any possible foreign matter. Tighten Swivel Nut 5. Use a marker or pen to mark a line on the coupling nut and unit panel. Then tighten the coupling nut an additional one-quarter turn. The line will show the amount that the nut turns. Clean and Lubricate Couplings 2. Thoroughly lubricate the threads, o-rings, diaphragms and all internal coupling surfaces with polyolester refrigerant oil. 3. Position the fittings on the correct connections on the condenser and ice machine. Final Connections: 4a. Begin to tighten the couplings together by hand. Continue to turn the swivel nuts by hand until it is certain that the threads are properly engaged. Rotate Swivel Nut ¼ Turn More 4b. Using two wrenches, one to rotate the swivel nut and one to hold the tubing in place, tighten each coupling. It is CRITICAL that ONLY the NUT on the pre-charged tube be turned, or the diaphragms will be torn by the piercing knives and become loose in the refrigeration system causing severe operational problems. Note: As the coupling is tightened, the diaphragms in the quick connect couplings will begin to be pierced. As that happens, there will be increased resistance to tightening the swivel nut. 6. After all connections have been made check the couplings for leaks. 7. Add cork tape to the swivel nut of the suction line to insulate it. Be sure all exposed tubing of the suction line is insulated. Note: The system charge is contained in the receiver tank of the ice machine. Only “holding" charges are present in the “pre-charged" tubing or the condenser.

April 2002 Page 26 Eclipseä 600, 800, 1000 Controller Operation The controller has seven indicator lights and four push buttons. Indicator Lights Bin Full: On when the bin is full, blinks on and off as ice falls during a harvest cycle. Freeze: On when the unit is in the Freeze cycle. Blinks when a freeze cycle is pending. Harvest: On when the unit is in the Harvest cycle. Clean: Blinks when the unit is in the first part of a Clean cycle, on steady when switched to the second part. Off: On when the unit has been switched off, blinks when the unit is preparing to shut off. Water Diagnostic: On when the controller has identified a problem with the water system. Flashes a code to specify what area may be the problem. Cycle Definitions: Freeze: The refrigeration system is operating to remove heat from the evaporators. The compressor, fan motor, and water pump are on. Harvest: The refrigeration system and water system are operating to harvest the ice and rinse the reservoir. The compressor is on for the full cycle, the pump is off and then on, the purge valve is open and then closed, the inlet water valve is closed, opens and recluses. The vapor and condenser by-pass valves are open during the entire harvest cycle. Clean: The inlet water valve opens to fill the reservoir. The water pump starts. The Clean indicator light is switched On. A manually initiated rinse flushes the system. Refrigeration Diagnostic: On when the controller has identified a problem with the refrigeration system. Flashes a code to specify what area may be the problem. 8 9 Push Buttons Freeze: Push and Release to start the unit 7 Harvest: Push and Release to start a manual harvest of ice. 6 Clean: Push and Release to start the first part of the cleaning process. Push and release again to start the second part of the cleaning process. 5 Off: Push and Release to shut the machine off at the end of the next harvest cycle. Push and Hold for three seconds to stop the machine. Push and Hold again to go into the Purge Adjustment or Error Recall mode. 4 3 PUSH BUTTON CONTROL SWITCHES INDICATOR LIGHTS: BIN FULL FREEZE HARVEST CLEAN 2 1 OFF DIAGNOSTIC LIGHTS: WATER REFRIGERATION Controller Lights and Push Buttons April 2002 Page 27 Eclipseä 600, 800, 1000 Initial Start Up Pre Start A soak-out period of four hours is optional for this system. If desired, powering the compressor unit for four hours prior to start up allows the crankcase heater to warm up the oil in the compressor. Start Up 1. Connect power to the condensing unit and move its toggle switch to Run or On. 2. Open the water supply valve. After a few minutes ice will begin to form on the evaporators. When enough ice has formed to nearly empty the water reservoir, the controller will refill the reservoir. The next time the water level drops that far, the ice is ready for release and the Controller will initiate a Harvest cycle. · The Freeze light goes out and the Harvest light switches on. · The vapor inlet valve in the ice making section opens. 3. Connect or reconnect power to the ice making section. · In the CP unit, the condenser by-pass valve 4. Observe the lights on the controller: · The water pump stops. · The purge valve opens. opens and the liquid inlet valve closes · All flash on as the power supply is reconnected. · The two red lights blink for 20 seconds while some green lights are on. CME810: bin full and harvest. CME686: bin full, harvest and clean. Note: If the light pattern does NOT match – do not start the machine. Install a replacement controller set to the correct program. · The red lights and harvest lights go out. · The Off light turns on. · The Bin Full light will be on for a few seconds. Refrigerant vapor flows into the evaporators where it condenses, discharging its latent heat. The evaporators warm up and melt the bond between the ice cube surface and the evaporator cells. After about 20 seconds the water pump re-starts to purge water out of the reservoir. After a few more seconds the purge valve closes and the inlet water valve opens for a few seconds to add some water to the reservoir. The water pump then circulates this water over the evaporators, and ice begins to fall. At this point the machine is ready for start up. 5. Push and Release the Freeze button to start the machine. · The Freeze light will begin to blink. · The Purge valve will open for a few seconds and then close. As the ice falls, it passes through two infrared light beams. These beams, when interrupted, signal to the Controller that ice is harvesting. The interruptions are shown by the blinking of the Bin Full light. The first Harvest cycle continues for about 5 minutes. The controller will use the ice release time measured during this time to compute the next harvest cycle. · The Inlet water valve will open and fill the reservoir with water. · The Water pump will begin to circulate water over the evaporators. When the reservoir is full, the Freeze light will stop blinking and the controller will close a circuit to the compressor contactor to start the first freeze cycle. Note: Because the condensing unit is external to the ice making section, no visible signs of operation will be noticeable until the water begins to cool and frost forms on the evaporator tubing. 6. Go to the condensing unit and confirm that the compressor and fan motor are operating. Warm air will be discharged from the condenser. At the end of the Harvest cycle the ice machine will switch back into a Freeze cycle. The inlet water valve will open to re-fill the reservoir with water, and the cycle repeats. Note: Machines are shipped from the factory with the purge level set to accommodate average water conditions. To achieve optimal machine performance, set the purge level to the minimum setting. See the next page. 7. Attach the front panel to the ice making section. May 2002 Page 28 Eclipseä 600, 800, 1000 Purge Adjustment Adjustments Note: While the amount of water purge is adjustable, only those installations with a water supply known to be excellent (very low TDS) should adjust to the minimum setting. See below for purge adjustment instructions. Cube Size: Cube size is fixed and cannot be adjusted. Thermostatic Expansion Valve: The TXVs are not adjustable, do not attempt to adjust any of them. How to Adjust the Amount of Water Purge If there was a problem during Initial Start Up: Adjustment is done by use of the control buttons on the AutoIQ Controller. Examine the next section to become familiar with the AutoIQ Controller before beginning. 1. If the machine is on, push and hold the OFF button for more than 3 seconds, then release it. This switches the machine Off. 2. Push and hold the OFF button for more than 3 seconds (just until all lights flash on) then release it. Do not hold it in it too long. 3. Examine the green lights. They should have all flashed once, then certain ones will have turned on to indicate which purge level the machine is set at. There are 5 levels of purge available: · 1. Maximum Purge is when All 5 lights are ON. Use for extreme water conditions. · 2. Heavy Purge is when these 4 lights are ON: Freeze, Harvest, Clean, Off. Use for severe water conditions. If an error light came on, check the following. 1. Water error. A water error could have been determined by the AutoIQ Controller if the inlet water valve does not fill the reservoir, or if the water pump does not start and lower the water level. 2. Refrigeration error. A refrigeration error could have been determined by the AutoIQ Controller if the water temperature did not drop during the freeze cycle. The controller will next check the compressor discharge temperature, If the discharge temperature is too low, the refrigerant error light will be switched on, and the machine will Shut Down. Note: Reset and restart the machine by pushing and releasing the Off push button switch, and then pushing and releasing the freeze push button switch. · 3. Standard Purge (factory setting) is when these 3 lights are ON: Harvest, Clean, Off. Use for moderate to severe water conditions. · 4. Moderate Purge is when these 2 lights are ON: Clean, Off. This is for typical water conditions. · 5. Minimum Purge is when this light is ON: Off. For excellent water conditions. Adjust by pushing and releasing the Freeze button. Pushing and releasing the Freeze button increases the purge one level up to the maximum, then it goes to the minimum. 4. The machine will automatically restart after 60 seconds of no switch inputs, or restart the machine by pushing in and holding the Off button for more than 3 seconds, then releasing it. The unit will then be Off. From there the machine may be placed in a freeze cycle by pushing and releasing the Freeze button. April 2002 Page 29 Eclipseä 600, 800, 1000 System Operation: This section is intended for the technician. Understanding it is not necessary for the normal operation and maintenance of this ice making system. Major Components: Ice making section sub-system: · Controller, · Ice Sensors, · Water Level Sensor, · Transformer, · Evaporators, · Expansion Valves, · Check Valves, · Vapor Inlet Valve, · Water Pump, · Inlet Water Valve · Purge Valve. Compressor Package sub-system: · Compressor, · Contactor, · Condenser Bypass Valve, · Liquid Inlet Valve, · Receiver, · Accumulator, · CPR Valve, · Headmaster. The controller receives input from the water level sensor, ice sensor and temperature sensor. It then actuates various loads in the ice making section and in the condensing unit to control ice making. It also responds to push button input and displays cycle and diagnostic indicators. Freeze: At the ice making sub system, the controller fills the water reservoir and starts the pump and compressor to make ice. The vapor inlet valve is closed. Water circulates over the evaporators until it begins to freeze to the evaporators. As ice builds up the water level in the reservoir falls until it reaches a point where the water level sensor indicates to the controller that the water level is low. At that point, about half-way through the freeze cycle, the controller opens the water valve to refill the reservoir. The second time the water level drops in the freeze cycle indicates to the controller that the freeze cycle is complete. In the condensing unit sub-system (compressor package and condenser) the compressor is on, the condenser by-pass valve is closed, the fan motor is rotating the fan blade. Harvest: At the ice making sub system, the controller shuts off the pump, opens the vapor inlet valve, opens the purge valve. The controller also controls items in the condensing unit, where the condenser by pass valve is opened. After a set time the water pump restarts and shortly after that the purge valve closes. The inlet water valve opens to add water to the reservoir. Ice releases and falls into the bin or dispenser. Condenser sub-system: · Coils · Fan Motor Ice Sensors Normal Bin Full April 2002 Page 30 Eclipseä 600, 800, 1000 Refrigeration Details: The compressor provides the force that circulates refrigerant in the refrigeration system. During freeze, when the vapor inlet and condenser by pass valves are closed, discharge gas flows from the compressor into the condenser, where its heat is discharged into the air stream. Liquid refrigerant flows out of the condenser and through the normally open liquid line outlet valve on its way to the receiver inlet. Under low ambient/low pressure conditions, the headmaster valve closes the liquid outlet of the condenser and opens a bypass route to direct refrigerant gas to the receiver inlet until discharge pressure builds back up to the headmaster’s set point. From the receiver liquid outlet, liquid refrigerant flows into the liquid line and into the ice making section. At the ice making section, the refrigerant flows into the expansion valves where a pressure change takes place. The liquid refrigerant moves from the expansion valves into a low-pressure area (the evaporators) where it can rapidly evaporate and absorb heat. Heat is absorbed from the copper evaporator tubing, attached copper, tin, plastic and the water flowing over the evaporators. Check valves prevent the evaporating refrigerant from flowing into the wrong evaporator. The low-pressure refrigerant gas then flows into the suction line, which carries it back to the condensing unit, where it enters the accumulator. In the accumulator most of any liquid carried with the suction gas is separated and only vapor flows out of the accumulator through the CPR valve and to the compressor where the cycle continues. During harvest discharge gas flows through the open condenser by pass valve into the vapor line. Power is also applied to the coil of the liquid inlet valve, closing it. At the same time, in the ice making section, the vapor inlet valve opens. Discharge gas, combined with some vapor from the receiver’s outlet, then flows through the vapor line to the evaporator inlets. The gas-vapor combination, when entering the relatively cold evaporators, condenses, transferring latent heat to the evaporators, which warms them. Ice releases and falls into the bin. The low-pressure refrigerant then flows out of the evaporators and into the suction line. The suction line brings the refrigerant, now consisting of a vapor-liquid combination, to the accumulator. From the accumulator the vapor-liquid combination (now more vapor than liquid) goes to the Crankcase Pressure Regulator valve which limits the amount of dome pressure in the compressor, where the cycle continues.

Receiver TXVs Vapor Inlet Valve Check Valves Evaporator April 2002 Page 31 Eclipseä 600, 800, 1000 Technicians Only: Freeze Cycle Sequence of Operation This sequence begins with a restart after the unit has shut off with the bin full. Ice has been consumed, causing the ice sensors to become un-blocked. 6. Assuming that the system is working normally, the controller will shut the water pump off for a few seconds when the reservoir’s water temperature reaches a pre-set point. 1. The controller switches off the bin full light (four minutes has to have passed since the machine shut off on bin full for the machine to restart) and switches on the Freeze light. 7. As the machine makes ice the water level in the reservoir falls. When it reaches the point where the float stem blocks the upper infrared beam in the water level sensor the controller opens the inlet water valve to refill the reservoir. The water valve stays on until the float stem rises to block the lower beam in the water level sensor. 2. The purge valve is opened and the pump started. 3. After the purge valve closes the inlet water valve opens and fills the reservoir. Note: If the water reservoir does not fill within the time period expected the controller will shut off and blink the water diagnostic light. It will re-try to fill the reservoir in 20 minutes. If successful the freeze cycle will continue. 4. The compressor and fan motor start and the freezing process begins. 5. The controller measures the reservoir water temperature and compares it to the temperature it expects to find at that point in the cycle. If normal, nothing happens. 8. The freezing process continues until the float stem blocks the upper beam for the second time. That signals to the controller that the freezing process is complete. Inlet Water Valve If high, the controller checks the discharge temperature. If that is normal, Purge Valve nothing happens. If that is low, the controller starts a diagnostic process that could lead to the unit shutting off, as the refrigeration Water Pump system may not be operable. Water Schematic April 2002 Page 32 Eclipseä 600, 800, 1000 Technicians Only: Harvest Cycle Sequence of Operation Slow Ice Release At the beginning of harvest, the controller: · Shuts off the Freeze light · Turns on the Harvest light · Opens the vapor inlet valve · Opens the condenser bypass valve · Closes the normally open liquid inlet valve · Shuts off the water pump · Opens the purge valve · Begins to time the harvest cycle If ice releases slowly the controller will extend the harvest cycle until it ice quits falling within the normal harvest time or until it reaches the pre-set maximum time. The controller will then return the unit to the freeze cycle. No Ice Released If no ice is sensed harvest continues until it reaches its pre-set maximum, when the controller switches the unit back into freeze. Shut Down - Maximum Harvest Time When the ice falls off the evaporators, it passes through the two infrared light beams emitted by the ice sensors in the ice chute. The falling ice breaks the beams, signaling to the controller that ice is being released. During harvest the controller: · Blinks the Bin Full light at every light beam interruption to indicate that ice is being sensed · Changes the time measured from the beginning of harvest to the time the last cube was sensed. First Harvest Cycle The first harvest cycle after a restart continues for a default period of about 5 minutes. The next cycle’s harvest time will be determined from the actual time used to release ice in this cycle, and will likely be much shorter. If a maximum harvest time is reached again during the next harvest cycle, the controller will shut the system down and blink the refrigeration diagnostic light. It will automatically attempt a restart in 50 minutes. If the maximum harvest time is reached again in the next two consecutive cycles, the controller will repeat the shut down and restart process. If the system still requires a maximum length harvest cycle the controller will shut the unit down and must be manually reset. Purge Valve The purge valve is open for a fixed time period. At the beginning of that time the pump is off, but after the time determined by the Purge setting in the controller, the pump starts and forces water out of the reservoir. The pump stays on after the purge valve closes. The inlet water valve opens for a few seconds to add water (but not fill) the reservoir. End of Cycle At the end of the harvest cycle the controller switches the Harvest light off and the Freeze light on. If the ice sensors had been blocked continuously for more than 20 seconds the controller senses this as Bin Full and would then shut the machine off and turn on the Bin Full light. At the beginning of the Freeze cycle the inlet water valve is turned on to fill the reservoir and the cycle repeats. April 2002 Page 33 Eclipseä 600, 800, 1000 Power and Water Interruptions Short (less than one second) power interruptions cause no change in operation. Longer interruptions initiate a restart process: · Freeze light blinks on controller · Compressor is off · Vapor inlet valve opens · Liquid inlet valve closes · Purge valve opens · Pump starts, empties the reservoir · Purge valve closes · Inlet water valve fills reservoir · The Compressor starts · Vapor inlet valve closes · Liquid inlet valve opens · Freeze cycle proceeds for 30 seconds · Harvest cycle initiated, continues for 4 minutes · Normal freeze cycle starts Water Interruptions The water level sensor checks for water fill whenever the water inlet valve is activated. If the water level sensor does not record a full reservoir within the pre-set time, the controller · shuts the unit off · blinks the water diagnostic light two times and repeats After 20 minutes the inlet water valve is powered again and if the water level sensor is satisfied, the unit is restarted if the controller still doesn’t sense a full reservoir it keeps the unit off for another 20 minutes and then restarts the water fill process. The process of retrying water fill will continue until a full reservoir is sensed. There is no time limit. April 2002 Page 34 Eclipseä 600, 800, 1000 Sanitation and Cleaning It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition. Without human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of their water systems with a specifically designed chemical. This chemical dissolves mineral build up that forms during the ice making process. Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned and sanitized. The ice machine’s water system should be cleaned and sanitized a minimum of twice per year. In Place Cleaning of the Ice Machine Water System: 1. Remove all ice from the bin or dispenser. 9. After the ice machine cleaner has circulated for 10 minutes, push and release the Clean button. This starts the rinsing process. The Clean indicator light will be ON. Note: The rinse process flushes any residual cleaner out of the ice machine’s water system. 2. Remove the front panel. 10. Continue the rinsing process for 20 minutes, then push the off button to switch the machine off. 3. Push and release the Harvest button (this releases any ice that may be on the evaporators and warms them up). 11. Go to the next step to sanitize the machine or go to step 19 to finish the cleaning process. 4. Wait for the machine to finish the Harvest cycle (the machine will stop). 5. Remove the evaporator cover, the splash shields, the cube deflector, the cascading shield and the ice sensors. Place the cascading shield and the cube deflector in a separate container.

Reverse to reassemble. April 2002 Page 38 Eclipseä 600, 800, 1000 Ice Sensors The ice sensors, located in holders in the base of the ice making section, must be clean and free of mineral scale to provide the controller with accurate information. To clean them they must be removed from their installed positions. 1. Remove front panel. 2. Push and release the Harvest button to release ice. When ice quits falling, push and hold the Off button until the machine stops. 3. If side access is available, remove both side panels. 13. Wipe the lens clean with a soft cloth dipped in an ice machine cleaner solution (3 parts water to 1 part ice machine cleaner). Do NOT use any abrasives on the lenses. 14. Return the tray to its normal position. Be sure it snaps into place. The gray wire must be secured under the black plastic clip. 15. Return each ice sensor to its normal position. Be sure no wires are pinched in the mounting sockets. 4. Remove evaporator cover. 5. Remove lower splash panel. 6. Remove inspection cover. 7. Remove cascading shield. 16. Remount the cascading shield. 8. Locate sensor mounting holes, located at the lower left and right corners of the freezing compartment. 9. Push the sensors in at their mounting holes. 10. Reach in the freezing compartment and pull the sensors out through the inspection hole until they are at a comfortable distance from the cabinet. 11. Each sensor contains a removable tray. One tray contains the infrared emitters, the other the infrared receiver. Each lens must be clean and free of scale for proper operation. The trays may be removed from their holders for better access. 12. Push the tray in with a finger or thumb until the tray flips out of its socket. 17. Return the inspection cover to its normal position. 18. Return the lower splash panel to its normal position. 18. Return the evaporator cover to its normal position. 19. Return the side panels to their normal positions. 20. Push and release the Freeze button. 21. Return the front panel to its normal position. Ice Sensor Diagnostics Diagnostics assume that the control system is working but may not be able to sense cubes. Its purpose is to determine which component may be at fault - the controller or the ice sensors. Unplug thermostat (if used) and check bin full light, if off place an object between the ice sensors, after 5 seconds the Bin Full light will be glowing steadily, if not check operation of sensors by unplugging #4. Bin Full light will go on after 5 seconds, If not, replace controller. If the light does go on, replace ice sensor set. April 2002 Page 39 Eclipseä 600, 800, 1000 Water Level Sensor Maintenance In most cases the water level sensor will not require maintenance. However, if the area where the ice making section is located is dusty or there is a high concentration of minerals in the water, the infrared emitter and detector lenses inside the sensor may need to be wiped off. If it is much less than that, there is something wrong with either the power supply to the controller or the controller itself. If the voltage measures correctly proceed to the next step. 2. Push and hold the Off button until the machine stops. 5. Reconnect the harness. Be SURE it is on properly and has a good connection. To confirm, unplug the harness from the water sensor and redo step #4 at the end of the harness. Then plug the harness back onto the sensor. 3. Unplug sensor wire harness from sensor. Harness Connected Voltage (DC) 4. Remove two screws holding dust cover to sensor. 6. At the controller, measure the voltage between the top and bottom pins on connection #2. This should be between the ranges in the table below. If it outside this range there is a problem in the sensor and it should be changed out. If it is within this range, proceed to the next step. 1. Remove front panel. 5. Wipe the four lenses with a cotton swap soaked in potable water. Clean Lenses Clean Lenses 7. Place negative voltmeter probe on the bottom terminal (yellow wire). Place the other on the one just above it (terminate freeze sender - white wire). Move the float stem/stick up and down and note the voltage changes. There should be a significant change between when it is blocked to when it is not blocked. If there is NO change, the sensor may be dirty or has failed. Remove the dust cover from the sensor to clean it. Water Level Sensor, Dust Cover Removed 6. Return the dust cover to its original position, secure with the original screws. Note: The sensor must be properly reassembled. When looking at the terminals of the sensor, they must be in the lower right corner. If they are in the upper left remove the sensor’s dust cover and reverse the board. Later models have an UP arrow on the right side of the circuit board. 7. Reconnect wire harness. 8. Push and release the Freeze button. 9. Return the front panel to its normal position. Water Level Sensor Diagnosis Tools Needed: Digital voltmeter that can read DC Note: Ambient light can affect this test. Shade the sensor if needed. 1. Unplug water sensor harness from controller (connection #2). 2. Confirm that the power to the machine is ON and that there is at least one light on the board that is glowing. If not, check the transformer. 3. Set the voltmeter to DC and use a scale low enough to measure less than 40 Volts. White - Blocked about 5 VDC White - Unblocked less than when blocked 8. With the voltmeter probe still on the bottom terminal (connection #2), place the other probe on the second pin from the top (sump full sender - red wire). Move the float stick up & down, changes in voltage should be the same as in step 7. Yellow (bottom) 4. Measure the voltage between the top and the bottom pins on the controller at connection #2 (the bottom is ground or negative). · Harness unplugged - .5 to 2 VDC Yellow (bottom) Red - Blocked about 5 VDC Red - Unblocked less than when blocked 9. If all voltages check out, there is nothing wrong with the sensor or the voltage it receives from the controller.
