Section 2 Installation Instructions Location of Ice Machine The location selected for the ice machine must meet the following criteria. If any of these criteria are not met, select another location. • The location must be free of airborne and other contaminants. • The air temperature must be at least 1.6°C, but must not exceed 43.4°C. • The location must not be near heat-generating equipment or in direct sunlight. • The location must not obstruct air flow through or around the ice machine.
Installation Instructions Section 2 Leveling the Ice Storage Bin Air-Cooled Baffle 1. Screw the leveling legs onto the bottom of the bin. 2. Screw the foot of each leg in as far as possible. ! Caution The legs must be screwed in tightly to prevent them from bending. The air-cooled baffle prevents condenser air from recirculating. To install: 1. Remove the back panel screws next to the condenser. 2. Align the mounting holes in the air baffle with the screw holes and reinstall the screws. 3.
Section 2 Installation Instructions Electrical Service GENERAL FUSE/CIRCUIT BREAKER ! Warning All wiring must conform to local and national codes. A separate fuse/circuit breaker must be provided for each ice machine. Circuit breakers must be H.A.C.R. rated. GROUND FAULT CIRCUIT INTERUPTER 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 GENERAL GUIDELINES FOR ROUTING LINE SETS Condensers must be mounted horizontally with the fan motor on top. First, cut a 64 mm circular hole in the wall or roof for tubing routing. The line set end with the 90° bend will connect to the ice machine. The straight end will connect to the remote condenser. Remote condenser installations consist of vertical and horizontal line sets between the ice machine and the condenser.
Section 2 Installation Instructions Make the following calculations to make sure the line set layout is within specifications. CALCULATING REMOTE CONDENSER INSTALLATION DISTANCES 1. Insert the measured rise into the formula below. Multiply by 1.7 to get the calculated rise. (Example: A condenser located 3 meters above the ice machine has a calculated rise of 5 meters. Line Set Length The maximum length is 30 m. The ice machine compressor must have the proper oil return.
Installation Instructions Section 2 LENGTHENING OR REDUCING LINE SET LENGTHS REMOTE RECEIVER SERVICE VALVE In most cases, by routing the line set properly, shortening will not be necessary. When shortening or lengthening is required, do so before connecting the line set to the ice machine or the remote condenser. This prevents the loss of refrigerant in the ice machine or condenser. The receiver service valve is closed during shipment. Open the valve prior to starting the ice machine.

Ice Machine Operation Section 3 Self-Contained Air-Cooled Q460/Q660/Q1060 INITIAL START-UP OR START-UP AFTER AUTOMATIC SHUT-OFF FREEZE SEQUENCE 1. Water Purge The compressor is on for 30 seconds prior to water flow, to prechill the evaporator. 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.

Automatic Shut-Off 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. 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 The ice thickness probe is factory-set to maintain the ice bridge thickness at 3 mm. 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. Important The harvest sequence water purge is factory-set at 45 seconds. A shorter purge setting (with standard water supplies such as city water) is not recommended. This can increase water system cleaning and sanitizing requirements.

Section 4 Maintenance Section 4 Maintenance Interior Cleaning and Sanitizing GENERAL Step 3 Remove all ice from the bin. 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 B. Remove the ice thickness probe • C.

Section 4 Maintenance D. Remove the white vinyl water distribution tubing • Disconnect the hose from the water pump outlet. • Disconnect the hose from the dump valve (the tubing pressure fits - pull tubing into evaporator compartment). F. Remove the water level probe • Loosen the screw that holds the water level probe in place. The probe can easily be cleaned and sanitized at this point without proceeding to step 2.
Maintenance Section 4 Step 9 While components are soaking, use 1/2 of the cleaner/water solution to clean all foodzone 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 (bottom of the water trough) • Step 12 Use 1/2 of the sanitizer/water solution to sanitize all foodzone surfaces of the ice machine and bin (or dispenser). Use a cloth or sponge to liberally apply the solution.
Section 4 Maintenance Step 16 The ice machine will stop after the sanitize cycle (approximately 30 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 Repeat step 6 for hand sanitizing. Step 18 Mix a solution of sanitizer and warm water.
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. 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.

Maintenance Section 4 Ice Machine Inspection Cleaning the Condenser Check all water fittings and lines for leaks. Also, make sure the refrigeration tubing is not rubbing or vibrating against other tubing, panels, etc. GENERAL Do not put anything (boxes, etc.) on the sides or back of the ice machine. There must be adequate airflow through and around the ice machine to maximize ice production and ensure long component life.
Section 4 Maintenance 4. Straighten any bent condenser fins with a fin comb. “COMB” DOWN ONLY CONDENSER FIN COMBS AlphaSan® The goal of AlphaSan® is to keep the plastic surfaces of an ice machine cleaner, by reducing or delaying the formation of bio-film. The active ingredient in AlphaSan® is the element silver in the form of silver ions (Ag+). AlphaSan® slowly releases silver ions via an ion exchange mechanism.
Maintenance Section 4 Removal from Service/Winterization GENERAL REMOTE ICE MACHINES 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 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. 1. Move the ICE/OFF/CLEAN switch to OFF. 2.
