Ice Machine Operation Section 3 Sequence Of Operation NOTE: The toggle switch must be in the ice position and the water curtain must be in place on the evaporator before the ice machine will start. 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 SAFETY TIMERS 5. Water Purge The control board has the following non-adjustable safety timers: The harvest valve(s) opens at the beginning of the water purge to divert hot 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 (turns on) and de-energizes (turns off) strictly by time.
Ice Machine Operation Section 3 Operational Checks ICE THICKNESS CHECK GENERAL The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8" (.32 cm). Manitowoc ice machines are factory-operated and adjusted before shipment. Normally, new installations do 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 • During the harvest sequence water purge, the water fill valve energizes and de-energizes by time. The water purge must be at the factory setting of 45 seconds for the water fill valve to energize during the last 15 seconds of the water purge.

Section 4 Maintenance Section 4 Maintenance 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. ! Warning If you do not understand the procedures or the safety precautions that must be followed, call your local Manitowoc service representative to perform the maintenance procedures for you.
Maintenance Section 4 Guardian™ 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. The Guardian™ will not control mineral or other water borne buildup. Your water quality will determine the length of time before mineral buildup affects ice machine performance.
Section 4 Maintenance 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. An extremely dirty ice machine must be taken apart for cleaning and sanitizing.
Maintenance Section 4 SANITIZING PROCEDURE Use sanitizer to remove algae or slime. Do not use it to remove lime scale or other mineral deposits. 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. ! Caution Never use anything to force ice from the evaporator. Damage may result.
Section 4 Maintenance REMOVAL OF PARTS FOR CLEANING/SANITIZING 1. Turn off the electrical and water supply to the ice machine (and dispenser when applicable). 5. Use a soft-bristle brush or sponge (NOT a wire brush) to carefully clean the parts. ! Caution ! Warning Disconnect electric power to the ice machine (and dispenser if applicable) at the electric switch box before proceeding. ! Caution 2. Remove all ice from the bin. 3. Remove the water curtain and the components you want to clean or sanitize.
Maintenance Section 4 2. Ice Thickness Probe 1. Water Curtain A. Gently flex the curtain in the center and remove it from the right side. A. Compress the hinge pin on the top of the ice thickness probe. B. Slide the left pin out. STEP 1 STEP 2 COMPRESS HINGE PIN TO REMOVE SV3153 SV3135 Water Curtain Removal Ice Thickness Probe Removal B. Pivot the ice thickness probe to disengage one pin then the other. The ice thickness probe can be cleaned at this point without complete removal.
Section 4 Maintenance 3. Water Distribution Tube ! Warning Removing the distribution tube while the water pump is running will allow water to spray from ice machine. Disconnect the electrical power to the ice machine and dispenser at the electric service switch box and turn off the water supply. 4. Water Trough A. Depress tabs on right and left side of the water trough. B. Allow front of water trough to drop as you pull forward to disengage the rear pins.
Maintenance Section 4 Water Pump Water Level Probe 1. Remove the water trough. ! Warning ! Warning Disconnect the electrical power to the ice machine at the electrical disconnect before proceeding. 2. The water level probe normally does not require removal for cleaning. The probe can be wiped and cleaned in place or proceed to step 3. 3. Pull the water level probe straight down to disengage.
Section 4 Maintenance 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. Important The plunger and the inside of the enclosing tube must be completely dry before assembly.
Maintenance Evaporator Tray Removal 1. Remove the water trough. 2. Remove thumbscrew on left side of tray. 3. Allow left side of tray to drop as you pull the tray to the left side. Continue until the outlet tube disengages from the right side. Section 4 Drain Line Check Valve The drain line check valve normally does not require removal for cleaning. Water loss from the sump trough will indicate removal and cleaning are required. sv3154 1. Remove check valve and tube assembly. A.
Section 4 Maintenance Water Inlet Valve The water inlet valve normally does not require removal for cleaning. Refer to Section 5 for a list of causes for “No Water Entering Water Trough” or “Water Overflows Water Trough. 1. When the ice machine is off, the water inlet valve must completely stop water flow into the machine. 2. When the ice machine is on, the water inlet valve must allow the proper water flow through it. Set the toggle switch to ON. Watch for water flow into the ice machine.
Maintenance Section 4 Removal from Service/Winterization GENERAL 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. ! Caution If water is allowed to remain in the ice machine in freezing temperatures, severe damage to some components could result. Damage of this nature is not covered by the warranty. Follow the applicable procedure below. SELF-CONTAINED WATER-COOLED ICE MACHINES 1.
