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 completely purge the ice machine of old water. This feature ensures that the ice making cycle starts with fresh water.
Section 3 Ice Machine Operation HARVEST SEQUENCE AUTOMATIC SHUT-OFF 5. Water Purge 7. Automatic Shut-Off The air compressor (when used) and the harvest valve(s) open at the beginning of the water purge to divert refrigerant gas into the evaporator. The water pump continues to run, and the water dump valve energizes for 45 seconds to purge the water in the sump trough. The water fill valve energizes for the last 15 seconds of the 45-second water purge.
Ice Machine Operation Section 3 Operational Checks ICE THICKNESS CHECK GENERAL After a harvest cycle, inspect the ice cubes in the ice storage bin. The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8" (3.2 mm). Manitowoc ice machines are factory-operated and adjusted before shipment. Normally, a newly installed ice machine does not require any adjustment.
Section 3 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. ! Warning 45 second setting Disconnect electric power to the ice machine at the electrical disconnect before proceeding. Important The harvest sequence water purge is factory-set at 45 seconds.

Section 4 Maintenance Section 4 Maintenance Interior Cleaning and Sanitizing GENERAL Step 3 Remove all ice from the bin/dispenser. 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. The ice machine must be taken apart for cleaning and sanitizing. Step 4 Place the toggle switch in the CLEAN position.

Maintenance Section 4 Step 7 Mix a solution of cleaner and warm water. Depending upon the amount of mineral buildup, a larger quantity of solution may be required. Use the ratio in the table below to mix enough solution to thoroughly clean all parts. Solution Type Cleaner Water 1 gal. (4 l) Mixed With 16 oz (500 ml) cleaner Step 8 Use 1/2 of the cleaner/water mixture to clean all components.
Section 4 Maintenance Step 16 The ice machine will stop after the sanitize cycle (approximately 35 minutes). Place the toggle switch in the OFF position and disconnect power to the ice machine. ! Warning Disconnect the electric power to the ice machine at the electric service switch box. Step 17 Refer to step 6 and disassemble components. After dissembling proceed to step 18. Step 18 Mix a solution of sanitizer and warm water. Solution Type Sanitizer Water 6 gal.
Maintenance Section 4 ADDITIONAL COMPONENT REMOVAL The following components may be removed for easier access in some installations or they may need to be removed and cleaned to correct an operational problem. Door Removal 1. Use a phillips screwdriver to loosen the two screws securing the left and right doors. Do not remove they are secured to prevent loss. 2. 30 Inch and 48 Inch Models: To remove right front door lift up and remove (22 inch ice machines have a single door, lift to remove entire door).
Section 4 Maintenance Water Dump Valve The water dump valve normally does not require removal for cleaning. To determine if removal is necessary: COIL SPRING 1. Set the toggle switch to ICE. 2. Verify the water trough fills with water at the beginning of the freeze cycle. 3. While the ice machine is in the freeze mode, check the water trough to determine if the dump valve is leaking. If there is no or little water in the water trough (during the freeze cycle) the dump valve is leaking.
Maintenance Water-Cooled Condenser and Water Regulating Valve CVD1486 Only Section 4 Cleaning the Condenser GENERAL Symptoms of restrictions in the condenser water circuit include: • Low ice production • High water consumption • High operating temperatures • High operating pressures If the ice machine is experiencing any of these symptoms, the water-cooled condenser and water regulating valve may require cleaning due to scale build-up.
Section 4 Maintenance Guardian This product can be used on models S600C/S850C/ S1000C/S1200C/S1470C/S1870C/S2170C - this product cannot be used on IB600C/IB800C/IB1000C due to space constraints. Slime is a leading cause of ice machine breakdowns and biological growth is a health concern. The Guardian system releases chlorine dioxide on a controlled basis to inhibit the growth of bacteria and fungi that form slime and cause malodors in the food zone of ice machines.
Maintenance Section 4 Removal from Service/Winterization CVD1486 WATER COOLED CONDENSING UNIT GENERAL 1. Perform steps 1-11 in previous column. Special precautions must be taken if the ice machine is to be removed from service for an extended period of time or exposed to ambient temperatures of 32°F (0°C) or below. 2. Disconnect the incoming water and drain lines from the water-cooled condenser. 3. Insert a large screwdriver between the bottom spring coils of the water regulating valve.
Section 5 Before Calling For Service Section 5 Before Calling For Service Checklist If a problem arises during operation of your ice machine, follow the checklist below before calling service. Routine adjustments and maintenance procedures are not covered by the warranty. Problem Ice machine does not operate. Possible Cause No electrical power to the ice machine and/or condensing unit. High pressure cutout tripping. ICE/OFF/CLEAN toggle switch set improperly. Water curtain stuck open.
Before Calling For Service Problem Ice machine produces shallow or incomplete cubes, or the ice fill pattern on the evaporator is incomplete. Low ice capacity.
