Installation Instructions Section 2 Location of Ice Machine Leveling the Ice Storage Bin The location selected for the ice machine must meet the following criteria. If any of these criteria are not met, select another location. 1. Screw the leveling legs onto the bottom of the bin. 2. Screw the foot of each leg in as far as possible. • • • • The location must be free of airborne and other contaminants. The air temperature must be at least 35°F (1.6°C), but must not exceed 110°F (43.4°C).
Section 2 Electrical Service GENERAL WARNING All wiring must conform to local, state and national codes. VOLTAGE The maximum allowable voltage variation is ± 10% of the rated voltage at ice machine start-up (when the electrical load is highest).

Installation Instructions Section 2 Water Service/Drains Drain Connections Water Inlet Lines Follow 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 other equipment are working. (Check valves on sink faucets, dishwashers, etc.) • If water pressure exceeds the maximum recommended pressure, obtain a water pressure regulator from your Manitowoc distributor.

Ice Machine Operation Section 3 Ice Making Sequence of Operation Initial Start-Up Or Start-Up After Automatic Shut-Off 1. Water Purge Before the compressor starts, the water pump and water dump solenoid are energized for 45 seconds to purge the ice machine of old water. This ensures that the ice-making cycle starts with fresh water.
Section 3 Ice Machine Operation Operational Checks GENERAL Your Manitowoc ice machine was factory-operated and adjusted before shipment. Normally, a newly installed ice machine does not require any adjustment. To ensure proper operation, always follow these Operational Checks when starting the ice machine: • for the first time • after a prolonged out of service period • after cleaning and sanitizing Routine adjustments and maintenance procedures outlined in this manual are not covered by the warranty.
Ice Machine Operation HARVEST SEQUENCE WATER PURGE The harvest sequence water purge adjustment may be used when the ice machine is hooked up to special water systems, such as a de-ionized water treatment system. Important The harvest sequence water purge is factory-set at 45 seconds. A shorter purge setting is not recommended. This can increase water system cleaning and sanitizing requirements. • • The harvest sequence water purge may be set to 15, 30, or 45 seconds.
Section 4 Maintenance Section 4 Maintenance WATER-COOLED CONDENSER AND WATER REGULATING VALVE The water-cooled condenser and water-regulating valve may require cleaning due to scale build-up. Low ice production, high water consumption and high operating temperatures and pressures all may be symptoms of restrictions in the condenser water circuit. Because the cleaning procedures require special pumps and cleaning solutions, they must be performed by qualified maintenance or service personnel.
Maintenance Section 4 Interior Cleaning and Sanitizing GENERAL 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 or installation of the AuCS® accessory (Automatic Cleaning System). If required, an extremely dirty ice machine may be taken apart for cleaning and sanitizing.
Section 4 Maintenance Sanitizing Procedure Use sanitizer to remove algae or slime. Do not use it to remove lime scale or other mineral deposits. To initiate a sanitizing cycle using Manitowoc’s Patented Cleaning/Sanitizing Technology use the following procedure. Step 1 Set the toggle switch to the OFF position after ice falls from the evaporator at the end of a Harvest cycle. Or, set the switch to the OFF position and allow the ice to melt off the evaporator.
Maintenance Section 4 REMOVAL OF PARTS FOR CLEANING OR SANITIZING 1. Turn off the water supply to the ice machine at the water service valve. WARNING Disconnect electric power to the ice machine at the electric switch box before proceeding. 2. Remove the parts of the water curtain and the components you want to clean or sanitize. See the following pages for removal procedures for these parts. WARNING Wear rubber gloves and safety goggles (and/or face shield) when handling Ice Machine Cleaner or Sanitizer.
Section 4 Water Dump Valve The water dump valve normally does not require removal for cleaning. To determine if removal is necessary: 1. Locate the water dump valve. 2. Set the toggle switch to ICE. 3. While the ice machine is in the freeze mode, check the dump valve’s clear plastic outlet drain hose for leakage. A. If the dump valve is leaking, remove, disassemble and clean it. B. If the dump valve is not leaking, do not remove it. Instead, follow the “Cleaning Procedure” on page 4-3. Maintenance 3.
Maintenance Section 4 Water Pump WARNING Disconnect the electric power to the ice machine at the electric service switch box and turn off the water supply. 1. Disconnect the water pump power cord.
