Installation InstructionsSection 2Water Service/DrainsWATER SUPPLYLocal water conditions may require treatment of thewater to inhibit scale formation, filter sediment,remove chlorine, and improve taste and clarity.ImportantIf you are installing a Manitowoc Tri-Liminatorwater filter system, refer to the InstallationInstructions supplied with the filter system for icemaking water inlet connections.WATER INLET LINESFollow these guidelines to install water inlet lines: Do not connect the ice machine to a hot watersupply. Be sure all hot water restrictors installedfor other equipment are working. (Check valveson sink faucets, dishwashers, etc.)If water pressure exceeds the maximumrecommended pressure (80 psig), obtain a waterpressure regulator from your Manitowocdistributor.Install a water shut-off valve for the ice makingwater line.Insulate water inlet line to prevent condensation.2-6DRAIN CONNECTIONSFollow these guidelines when installing drain lines toprevent drain water from flowing back into the icemachine and storage bin: The ice machine comes equipped with a vinyldrain hose for use with floor drains.The floor drain must be large enough toaccommodate drainage from all drains.Insulate the bin drain to prevent condensation.Drain lines must have a 1″ (2.5 cm) drop per 40″(1 meter) of run, and must not create traps.ImportantThe Commonwealth of Massachusetts requires thatall water-cooled models must be connected only toa closed loop, cooling tower system.

Ice Machine OperationSection 3Ice Making Sequence of OperationINITIAL START-UP OR START-UP AFTERAUTOMATIC SHUT-OFF1. Pressure EqualizationBefore the compressor starts the hot gas valve isenergized for 15 seconds to equalize pressures duringthe initial refrigeration system start-up.2. Refrigeration System Start-UpThe compressor starts after the 15-second pressureequalization, and remains on throughout the entireFreeze and Harvest Sequences. The hot gas valveremains on for 5 seconds during initial compressorstart-up and then shuts off.At the same time the compressor starts, the condenserfan motor (air-cooled models) is supplied with powerthroughout the entire Freeze and Harvest Sequences.The fan motor is wired through a fan cycle pressurecontrol, therefore it may cycle on and off. (Thecompressor and condenser fan motor are wiredthrough a relay. As a result, any time the relay coil isenergized, the compressor and fan motor are suppliedwith power.)FREEZE SEQUENCE3. PrechillThe compressor is on for 30 seconds prior to waterflow to Prechill the evaporator.4. FreezeThe water pump starts after the 30-second Prechill.An even flow of water is directed across theevaporator and into each cube cell, where it freezes.When sufficient ice has formed, the water flow (notthe ice) contacts the ice thickness probe. Afterapproximately 7 seconds of continual water contact,the Harvest Sequence is initiated. The ice machinecannot initiate a Harvest sequence until a 6-minutefreeze lock has been surpassed.3-2HARVEST SEQUENCE5. HarvestThe water pump de-energizes stopping flow over theevaporator. The rising level of water in the sumptrough diverts water out of the over flow tube,purging excess minerals from the sump trough. Thehot gas valve also opens to divert hot refrigerant gasinto the evaporator.The refrigerant gas warms the evaporator causing thecubes to slide, as a sheet, off the evaporator and intothe storage bin. The sliding sheet of cubes contactsthe ice damper, opening the bin switch.The momentary opening and re-closing of the binswitch terminates the Harvest sequence and returnsthe ice machine to the Freeze Sequence (steps 3 - 4).AUTOMATIC SHUT-OFF7. Automatic Shut-OffWhen the storage bin is full at the end of a Harvestsequence, the sheet of cubes fails to clear the icedamper and will hold it down. After the ice damper isheld open for 7 seconds, the ice machine shuts off.The ice machine will remain off for 3 minutes beforeit can automatically restart.The ice machine remains off until enough ice hasbeen removed from the storage bin to allow the ice tofall clear of the damper. As the ice damper swingsback to the operating position, the bin switch recloses and the ice machine restarts (steps 1 - 2),provided the 3-minute delay period is complete.

Ice Machine OperationSection 3Operational ChecksGENERALYour Manitowoc ice machine was factory-operatedand adjusted before shipment. Normally, a newlyinstalled ice machine does not require anyadjustment.To ensure proper operation, always follow theseOperational Checks when starting the ice machine: for the first time after a prolonged out of service period after cleaning and sanitizingWATER LEVEL CHECKCheck the water level while the ice machine is in theclean mode and the water pump is running. Thecorrect water level is 1/4" (6.3mm) to 3/8″ (9.5mm)below the top of the standpipe.SIPHON CAP1/4” TO 3/8″(6.3 TO 9.5 MM) BELOW TOP OFSTANDPIPERoutine adjustments and maintenance proceduresoutlined in this manual are not covered by thewarranty.SV1689-2SIPHON SYSTEMTo reduce mineral build-up and cleaning frequency,the water in the sump trough must be purged duringeach harvest cycle.When the water pump de-energizes the level in thewater trough rises above the standpipe starting asiphon action. The siphon action stops when thewater level in the sump trough drops below thesiphon cap. When the siphon action stops, the floatvalve refills the water trough to the correct level.Siphon System CheckFollow steps 1 through 6 under water level check.Water LevelThe float valve is factory-set for the proper waterlevel. If adjustments are necessary:1. Verify the ice machine is level (see page 2-3).2. Remove the siphon cap from the standpipe.3. Place the main ICE/OFF/WASH toggle switch tothe WASH position, and wait until the float valvestops adding water.4. Adjust the water level to 1/4" (6.3mm) to 3/8"(9.5mm) below the standpipe:A Loosen the two screws on the float valvebracket.WATER LEVELSIPHONCAP5. Move the main ICE/OFF/ WASH toggle switchto the OFF position. The water level in the troughwill rise above the standpipe and run down thedrain.STANDPIPEDRAINSV1689-23-4B Raise or lower the float valve assembly asnecessary, then tighten the screws.6. Replace the siphon cap on the standpipe, andverify water level and siphon action by repeatingsteps 3 through 5.
