Section 2 Installation InstructionsPart Number 000001130 12/08 2-5Water Service/DrainsWATER SUPPLYLocal water conditions may require treatment of thewater to inhibit scale formation, filter sediment, removechlorine, and improve taste and clarity.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 installed forother equipment are working. (Check valves on sinkfaucets, dishwashers, etc.)• If water pressure exceeds the maximum(80 psig-551.5 kPA) recommended pressure, obtaina water pressure regulator from your Manitowocdistributor.• Install a water shut-off valve and union for both theice making and condenser water lines.• Insulate water inlet lines to prevent condensation.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 drain to the atmosphere. Do not vent thecondenser drain on water-cooled models.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).! WarningPERSONAL INJURY POTENTIALFor ice making, connect to a potable water supplyonly.ImportantIf you are installing a Manitowoc water filtersystem, refer to the Installation Instructionssupplied with the filter system for ice making waterinlet connections.ImportantThe Commonwealth of Massachusetts requiresthat all water-cooled models must be connectedonly to a closed loop, cooling tower system.
