Installation Section 2 Water Supply and Drain Line Sizing/Connections ,Caution Do not apply heat to water inlet valve or water drain fittings. Heating will damage the nonmetallic connector. Do not over tighten fittings. Two turns after hand tight is the maximum. • Local water conditions may require treatment of the water to inhibit scale formation, filter sediment, and remove chlorine odor and taste. • Connect ice making water inlet to potable water only. • Do not connect to hot water supply.
Section 2 Air Gap A greater than 1-inch air gap is built into the ice machine for back-flow prevention. This air gap exceeds NSF 12 requirements for back-flow prevention. This air gap is greater than 1" Cooling Tower Applications (Water-Cooled Models) A water cooling tower installation does not require modification of the ice machine. • Water pressure at the condenser cannot exceed 150 psig (1034 kPa). A special order unit is available that allows water pressure up to 350 psig (2413 kPa).
Installation Section 2 Remote Condenser and Condensing Unit Refrigeration System Installation Each ice machine head section ships from the factory with a refrigerant charge appropriate for the entire system operation. The serial tag on the ice machine indicates the refrigerant charge.

Installation 4. Section 2 Add together the calculated rise, calculated drop, and horizontal distance to get the total calculated distance. If this total exceeds 150 feet (45 meters), move the condenser/ condensing unit to a new location and perform the calculations again. Maximum Line Set Distance Formula Step 1. Measured Rise (R) 35 feet (10.7 meters) Maximum _____ x 1.7 = _____ Calculated Rise Step 2. Measured Drop (D) 15 feet (4.5 meters) Maximum _____ x 6.6 = _____ Calculated Drop Step 3.
Section 2 When lengthening or shortening lines, follow good refrigeration practices, purge with nitrogen and insulate all tubing. Do not change the tube sizes. Evacuate the lines and place about 5 oz (145 grams) of vapor refrigerant charge in each line. 1. Remove the dust caps from the line set, condenser and ice machine. 2. Apply refrigeration oil to the threads on the quick-disconnect couplers before connecting them to the condenser. 3.
Installation Section 2 ALTERNATE CONNECTIONS AT CONDENSING UNIT SCHRADER VALVES VALVES MUST REMAIN CLOSED AND BE PROTECTED FROM HEAT WHEN BRAZING (WRAP WITH WET RAG) 26 CHECK VALVE CONDENSER Step 3 Pressure Test and Evacuate Line Set and CVD Condensing Unit. • Shutoff valves for the line set must remain closed until pressure testing and evacuation are complete.
Section 2 Installation Step 4 Open Valves for the Line Set and Receiver. You will not hear refrigerant flow when the valves are opened. Refrigerant will not flow until the ice machine is started and the solenoid valve opens. • All valve caps must be reinstalled, tightened and leak-checked to assure no refrigerant leakage exists. • Counterclockwise opens all valves: A. Open the shutoff valves for the suction and liquid lines. B. Open the receiver service valve until back seated (when used).
Installation Step 5 Leak-Check the Refrigeration System. A. Connect power to the ice machine head section - Do not connect power to the CVD condensing unit. B. Press the power switch and energize the ice machine for 60 seconds to equalize pressures. C. Disconnect power to the ice machine head section. D. Leak-check line set connections, S trap and all factory joints in head section and condensing unit. E. Connect power to the CVD condensing unit and allow system to pump down.
Section 2 Starting the Ice Machine Starting the ice machine and completing the Operational Checks are the responsibilities of the owner/operator. Adjustments and maintenance procedures outlined in this manual are not covered by the warranty. REMOVE ICE THICKNESS PROBE SHIPPING BRACKETS. Remove and discard shipping brackets before starting the ice machine. Step 1 Ice machine must be programmed refer to “Touch Screen Features” on page 31 for details.
Installation Design & Burst Pressure Design Pressure 600 psig - 4137 kPa Burst Pressure 2500 psig - 17237 kPa Head Pressure Control Valve Do not use a fan cycling control to try to maintain discharge pressure. Compressor failure will result. Any remote condenser connected to a Manitowoc Ice Machine must have the OEM head pressure control valve installed. Manitowoc will not accept substitute “off the shelf” head pressure control valves.

Section 3 Operation Ice Making Sequence of Operation Control Board Timers The power button must be depressed and the water curtain/ice dampers must be in place on the evaporator before the ice machine will start. The control board has the following nonadjustable timers: • The ice machine control board will set its own install date after 100 freeze and harvest cycles. • The ice machine is locked into the freeze cycle for 6 minutes before a harvest cycle can be initiated.
Operation Safe Operation Mode Allows the ice machine to operate up to 72 hours if the ice thickness probe and/or water level probe sensors fail. • When the control board starts the safe mode, an alert is flashed on the display to notify the end-user they have a production problem. • The control board automatically initiates and monitors the safe mode. The control will automatically exit the safe mode if a normal signal is received from the input.

Section 4 Maintenance Cleaning and Sanitizing General You are responsible for maintaining the ice machine in accordance with the instructions in this manual. Maintenance procedures are not covered by the warranty. Clean and sanitize the ice machine every six months for efficient operation. If the ice machine requires more frequent cleaning and sanitizing, consult a qualified service company to test the water quality and recommend appropriate water treatment.
Maintenance Section 4 Exterior Cleaning Clean the area around the ice machine as often as necessary to maintain cleanliness and efficient operation. Wipe surfaces with a damp cloth rinsed in water to remove dust and dirt from the outside of the ice machine. If a greasy residue persists, use a damp cloth rinsed in a mild dish soap and water solution. Wipe dry with a clean, soft cloth. The exterior panels have a clear coating that is stain resistant and easy to clean.
Section 4 Maintenance Step 2 Remove all ice from the bin/ dispenser. Step 3 Press the Clean button and select “Turn off when complete”. Water will flow through the water dump valve and down the drain. Wait approximately 1 minute until the water trough refills and the display indicates Add Chemical. Add the proper amount of ice machine cleaner to the water trough by pouring between the water curtain and evaporator, then confirm the chemical was added.
Maintenance Section 4 Step 8 While components are soaking, use half of the cleaner/water solution to clean all food zone surfaces of the ice machine and bin (or dispenser). Use a nylon brush or cloth to thoroughly clean the following ice machine areas: • Side walls • Base (area above water trough) • Evaporator plastic parts - including top, bottom and sides • Bin or dispenser Rinse all areas thoroughly with clean water. SANITIZING PROCEDURE Step 9 Mix a solution of sanitizer and lukewarm water.
Section 4 Maintenance Parts Removal for Cleaning/Sanitizing Single evaporator is shown; Each evaporator will have a distribution tube and water curtain/damper. A. Remove the water curtain(s) • Gently flex the curtain in the center and remove it from the right side. • Slide the left pin out. B. Remove the ice thickness probe • Compress the hinge pin on the top of the ice thickness probe. • Pivot the ice thickness probe to disengage one pin then the other.
Maintenance Section 4 Preventative Maintenance Cleaning Procedure This procedure cleans all components in the water flow path, and is used to clean the ice machine between the bi-yearly cleaning/sanitizing procedure. Ice machine cleaner is used to remove lime scale and mineral deposits. Ice machine sanitizer disinfects and removes algae and slime. NOTE: Although not required and dependent on your installation, removing the ice machine top cover may allow easier access.
Section 4 Maintenance Cleaning the Air Filter and Condenser Removal from Service/Winterization The washable filter on self-contained ice machines is designed to catch dust, dirt, lint and grease. Clean the filter once a month with mild soap and water. A dirty condenser restricts airflow, resulting in excessively high operating temperatures. This reduces ice production and shortens component life. All Models 1. Clean and sanitize the ice machine. 2.
