Section 2 Installation InstructionsPart Number 000006520 11/11 9Water Supply and Drain RequirementsWATER SUPPLYLocal water conditions may require treatment of thewater to inhibit scale formation, filter sediment, andremove chlorine odor and taste.WATER INLET LINESFollow these guidelines to install water inlet lines:• If you are installing a Manitowoc Arctic Pure waterfilter system, refer to the Installation Instructionssupplied with the filter system for ice making waterinlet connections.• 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 maximumrecommended pressure of 80 psi (552 kPa), obtain awater pressure regulator from your Manitowocdistributor.• Install a water shut-off valve for both the ice makingand 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 ice machine drain lines.Insulate them to prevent condensation.• Vent the bin and ice machine drain to theatmosphere. Do not vent the condenser drain onwater-cooled models.• S3300 requires base drain connection (1" FPT).WATER-COOLED CONDENSER WATER PRESSUREWater pressure at the condenser cannot exceed 150psig (10.34 bar) with the standard water-regulatingvalve. Contact your distributor if your water pressure isgreater than 150 psig (10.34 bar). A special ordercondensing unit is available that allows water pressureup to 350 psig (24.13 bar)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 exceed90°F (32.2°C).• Water flow through the condenser must not exceed5 gallons (19 liters) per minute.• Allow for a pressure drop of 7 psi (0.5 bar) betweenthe condenser water inlet and the outlet of the icemachine.• Water exiting the condenser must not exceed110°F (43.3°C)..! CautionDo not apply heat to water valve inlet fitting. This willdamage plastic water inlet connection.ImportantThe Commonwealth of Massachusetts requires thatall water-cooled models must be connected only to aclosed loop, cooling tower system.
