Section 2 Installation InstructionsPart Number 80-1560-3 2-5Water Supply and Drain RequirementsWATER SUPPLYLocal water conditions may require treatment of thewater to inhibit scale formation, filter sediment, andremove chlorine odor and taste.AIR GAPAn air gap is incorporated into the design of the icemachine. Maximum water level is the top of the watertrough, which allows a minimum 1 inch air gap.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 maximumrecommended pressure, obtain a water pressureregulator from your Manitowoc distributor.• 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.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 Arctic Pure™ waterfilter system, refer to the Installation Instructionssupplied with the filter system for ice making waterinlet connections.! CautionDo not apply heat to water valve inlet fitting. This willdamage plastic valve body.
