Section 2 Installation InstructionsPart No. 80-1214-3 2-9Ice Machine Head Section Water Supplyand DrainsPOTABLE WATER SUPPLYLocal water conditions may require treatment of thewater to inhibit scale formation, filter sediment, andremove chlorine odor and taste.POTABLE WATER INLET LINESFollow these guidelines to install water inlet lines:• Do not connect the ice machine to a hot water supply.Be sure all hot water restrictors installed for otherequipment are working. (Check valves on sinkfaucets, dishwashers, etc.)• If water pressure exceeds the maximum (80 psig551.5 kPA) recommended pressure, obtain a waterpressure regulator from your Manitowoc distributor.• Install a water shut-off valve and union for both theice making and condenser water lines.DRAIN CONNECTIONSFollow these guidelines when installing drain lines toprevent drain water from flowing back into the icemachine and storage bin:• Drain lines must have a 1.5 inch drop per 5 feet ofrun (2.5 cm per meter), and must not create traps.• The floor drain must be large enough toaccommodate drainage from all drains.• Run separate bin and water-cooled condenser drainlines. Insulate them to prevent condensation.• Vent the bin and ice machine drain to theatmosphere. The ice machine drain requires an 18”vent. Do not vent the condenser drain on water-cooled models.• Drains must have a union or other suitable means toallow in place disconnection from the ice machinewhen servicing is required.• Insulate water inlet lines and drain lines to preventcondensation.Cooling Tower Applications(Water-Cooled Models)A water cooling tower installation does not requiremodification of the ice machine. The water regulatorvalve for the condenser continues to control therefrigeration discharge pressure.It is necessary to know the amount of heat rejection, andthe pressure drop through the condenser and watervalves (inlet and outlet) when using a cooling tower onan ice machine.• Water entering the condenser must not exceed 90°F(32.2°C).• Water flow through the condenser must not exceed 5gallons (19 liters) per minute.• Allow for a pressure drop of 7 psi (48 kPA) betweenthe condenser water inlet and the outlet of the icemachine.• Water exiting the condenser must not exceed 110°F(43.3°C).ImportantIf you are installing a Manitowoc water filter system,refer to the Installation Instructions supplied with thefilter system for ice making water inlet connections.Revised 8/2003Downloaded from www.Manualslib.com manuals search engine
