User information How the dispenser works Follett s /0I series automatic-load ice and water dispensers are equipped with Follett s lb (8kg)/day ice machine. In the continuous icemaking process, water freezes to the inside wall of the evaporator. A rotating stainless steel auger carries the ice to the top of the evaporator where it is compressed and extruded through an outlet port. The ice is then pushed through a tube to the storage hopper. When the hopper is full, a bin thermostat opens and shuts the ice machine off. When the dispense mechanism is activated, a dispense motor is turned on, causing the wheel to turn. This moves ice to the dispense chute where it drops by gravity into the container held below the chute. How SensorSAFE infrared dispensing works Follett s SensorSAFE infrared dispensing maximizes sanitation and minimizes the possibility of cross-contamination by eliminating physical contact between the cup or container and dispenser. Sensors in the panel use reflected infrared light to detect the presence of the container and send a signal to a control board which then activates the appropriate components for ice or water dispensing. The SensorSAFE infrared dispensing package includes a cleaning switch under the left side of the front cover which temporarily shuts off dispensing to allow cleaning of the panel and lenses. If the switch is not turned back on after cleaning, the dispenser automatically resets after two minutes for normal operation. SensorSAFE infrared dispensing also includes a time limit safety feature which automatically stops ice dispensing after one minute of continuous dispensing. Dispensing can be resumed by moving the container away from the dispenser and returning it to the activation zone. leaning/descaling and sanitizing Follett ice machines and dispensers, and their associated cleaning and sanitizing procedures, are designed for use with potable water sources. The presence, or suspected presence, of infectious agents may call for additional measures, including the replacement of components and more comprehensive disinfection measures. Follett recommends that these cleaning and sanitizing procedures be reviewed with the appropriate infectious agent subject matter experts to assure complete remediation. Periodic cleaning/descaling and sanitizing of Follett s ice and water dispenser and ice machine system is required to ensure peak performance and delivery of clean, sanitary ice. The recommended cleaning procedures that follow should be performed at least as frequently as recommended and more often if environmental conditions dictate. leaning of the condenser can usually be performed by facility personnel. leaning/descaling and sanitizing of the ice machine system should be performed by your facility s trained maintenance staff or a Follett authorized service agent. Regardless of who performs the cleaning, it is the operator s responsibility to see that this cleaning is performed according to the schedule below.

Service Ice machine Operation (all models) Follett s ice machine consists of four distinct functional systems: Harvesting system Refrigeration system Water system Electrical control system These four systems work together to accomplish the production and harvesting of ice. A problem in any one of these systems will result in improper operation of the entire ice production cycle. When troubleshooting the ice machine, it is important to analyze the entire system operation to determine which system is not functioning properly, then pinpoint the component within that system that is malfunctioning. Determine what corrective action must be taken before making any adjustments or replacing any components. The icemaking process The Maestro Plus ice machine uses a stainless steel jacketed evaporator and operates on a continuous freezing cycle. Water is supplied to the evaporator from the water reservoir where the water level is controlled by conductivity probes. When the ice machine is running, a layer of ice forms on the interior surface of the evaporator. This ice is continuously removed by a slowly rotating ( RPM) auger. The auger carries the ice upward into the cavity formed by the top bearing housing and the compression loop, where it is compressed to remove excess water. When the ice reaches the desired hardness it rotates within the cavity and is forced through a discharge port and compression nozzle and into the ice transport tube. The discharge tube and compression nozzle are slightly restricted to further compress the ice and produce the desired hardness. A solid state control board located in the electrical box of the ice machine controls the normal operation of the ice machine and monitors gearmotor torque. This control board will shut down the ice machine should an over-torque condition occur. It is very important that you familiarize yourself with the operational sequences detailed in this manual before attempting to service the ice machine. evaporator port ice transport tube compression nozzle water inlet auger IA/W, HIA, 0IA/W, 0HIA
Water system The water level in the evaporator is controlled by a fill solenoid (Fig ) and level detecting sensors. Water sensing rods (Fig. ) extend down into the reservoir at the end of the evaporator assembly. The system works via electrical conductivity as follows: One of the longest probes is a common. When water is between any of the other probes and the common, the P board will sense the activation. During normal operation, the water level rises and falls between the ormal High and ormal Low sensors. As water is consumed to make ice, the level will fall until the ormal Low sensor is exposed, triggering the water feed solenoid on. Water will fill until the ormal High sensor is activated. ote: The potable water dissolved solids content must be greater than 0 ppm for the water control system to function properly. If using reverse osmosis water filtration system, ensure T.D.S level is greater than 0 ppm.

Self-flushing At the completion of the 0 minute time delay, the machine checks for a cumulative one hour of ice making time since the last off-cycle flush. If the cumulative ice making time exceeds one hour, the machine will energize the drain valve P9 for 60 seconds to drain the evaporator. It will then refill with water, flush again, refill and begin making ice if the LOW BI LED is on. If the ice making time is less than hour, the machine will start and begin making ice without draining the evaporator. T.O.L.

AUTIO! Recharging of unit at other than factory specifications will void ice machine warranty. Refrigerant replacement requirements. on-contaminated refrigerant removed from any Follett refrigeration system can be recycled and returned to the same system after completing repairs. Recycled refrigerant must be stored in a clean, approved storage container. If additional refrigerant is required, virgin or reclaimed refrigerant that meets ARI standard 700-88 must be used.. In the event of system contamination (for example, a compressor burn out, refrigerant leak, presence of non-condensibles or moisture), the system must be repaired, evacuated and recharged using virgin or reclaimed refrigerant that meets ARI standard 700-88.. Follett orporation does not approve of recovered refrigerants. Improper refrigeration servicing procedures will void the factory warranty. Evacuation Evacuate the system to a level of 00 microns. When the 00 micron level is reached, close valves and both manifold and shut down the vacuum pump. Allow the system to sit for approximately 0 minutes. During this period the system pressure should not rise. If the system pressure rises and stabilizes there is moisture in the system and further evacuation is needed. If the pressure continues to rise check the system for leaks. Ice capacity test Ice machine production capacity can only be determined by weighing ice produced in a specific time period.. Remove top panel and hopper lid of unit.. Weigh and record weight of container used to catch ice.. Run ice machine for at least minutes.. atch ice for or 0 minutes.. Weigh harvested ice and record total weight. 6. Subtract weight of container from total weight. 7. onvert fractions of pounds to decimal equivalents (Ex. 6 lbs 8 oz = 6. lbs). 8. alculate production using following formula: 0 min. x wt. of ice produced Total test time in minutes = Production capacity/ hr. period 9. alculated amount per hours should be checked against rated capacity for same ambient and water temperatures in Ice Production Table (see page ).
