It is the responsibility of the technician to ensure that these requirements are met. Recharging icemaker to other than factory specifications will void the warranty. R404A icemaker charge specifications Model Charge Refrigerant type HCC1000A (air-cooled) 24oz (652g) R404A HCC1000W (water-cooled) 15oz (426g) R404A Refrigerant replacement requirements 1. Non-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. 2. 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. 3. Follett Corporation does not approve of recovered refrigerants. Improper refrigeration servicing procedures will void the factory warranty. Evacuation Evacuate the system to a level of 500 microns. When the 500 micron level is reached, close all valves. Allow the system to sit for approximately 20 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. Ambients Minimum Maximum Air temperature1 50°F/10°C 100°F/37.8°C Water temperature2 45°F/7°C 90°F/32.2°C 1Ambient air temperature is measured at the air-cooled condenser coil inlet. 2Ambient water temperature is measured in the icemaker water reservoir. Ice capacity test Icemaker production capacity can only be determined by weighing ice produced in a specific time period. 1. Replace all panels on icemaker. 2. Run icemaker for at least 15 minutes. 3. Weigh and record weight of container used to catch ice. 4. Catch ice for 15 or 20 minutes. 5. Weigh harvested ice and record total weight. 6. Subtract weight of container from total weight. 7. Convert fractions of pounds to decimal equivalents (ex. 6 lbs 8oz = 6.5 lbs). 8. Calculate production using following formula: 1440 min. x wt. of ice produced = Production capacity/24 hr. period Total test time in minutes 9. Calculated amount per 24 hours should be checked against rated capacity for same ambient and water temperatures in Ice Production Tables. 24 “Bin full” detection system The Follett Horizon icemaker incorporates a unique “bin full” detection system that consists of the shuttle and actuator. The shuttle incorporates a flag and sensor. Referencing the figure below, the normal running position of the flag is down, out of the sensor. When the bin fills to the top and ice can no longer move through the tube, the machine will force the shuttle flag up into the sensor, shutting the machine off. The shuttle actuator, located above the ice bin allows the ice to curl up within it when the bin is full. In this way, there are no loads generated that would tend to lift off the lid of the bin.
