User Manual for SM School Milk CoolerBeverage-AirUSING THE UNITOperation is simple, just keep it connected to the correctpower supply and the refrigerator will maintain theinternal temperature it has been set to. Keep the doorsand / or drawers closed as much as possible to avoidunnecessary run time.To manually defrost your milk cooler:1.Remove the product from your milk cooler and placeit in another refrigerated storage area.The controller displays the current internal temperature.2. Open the lids and doors of your milk cooler andunplug the power to the unit.Adjusting the set temperature lower will NOT cause thesystem to lower the temperature faster. When on, therefrigeration system is always operating at maximum.3. Wait approximately 30 min for the frost to melt anddrain to the floor drain. Times may vary with ambienttemperature in the room and ice build-up.The temperature was set at the factory at 38º F, butyou can adjust it to your own selected temperature. 30seconds after adjustment, the display automaticallyreverts to showing the current temperature.4.SM units must be manually defrosted periodically. “ColdWall” units like the SM maintain the air temperature ofthe cabinet at the set point by cooling the walls belowthe set point to approximately 20 F. Because the walls ofthe cooler are below the freezing temperature of water,ice may build up over time. It is important to occasionallymanually defrost the unit to minimize ice build-up.WARNING: DO NOT SCRAPE THE WALLS TO SPEED UPDEFROSTING.

User Manual for SM School Milk CoolerBeverage-AirFOR THE SERVICE TECH - R290Refrigeration service should only be attempted by a trained trade professional certified to work on R290 systems.Here are some critical service items.Other Information:This list does not qualify anyone to service the unit. It is areminder and checklist for the service tech. Keep these inmind for R290 service:Evacuation: It is critical that a refrigeration system beleak free and internally dry. A thorough evacuation witha good vacuum pump with a micron gauge attached is theonly way to ensure that the system is dry and ready for acharge of refrigerant. Wire nuts are NOT to be used when changing anelectrical part. The switches in this product are sealed, only exactreplacements may be used. The process tubes are to be used for service access. Cut out (with tubing cutter) refrigeration componentsthat are to be replaced. Do NOT un-braze.Charging: The system is critically charged and the propertype and amount MUST be weighed in. Because R290 can be vented into the air duringservice, the venting MUST be in an area free fromflame or spark. It must also be in a well ventilatedarea, with a nearby open window or door. A sign noting service of a system containing propanemust be attached to the unit during refrigerationservice. A combustible gas leak detector must be used toinform anyone in the area when propane is present inthe air.18Overcharge symptoms: Unit will cool properly butthe suction line temperature will be unusually cold.Compressor run time will be longer than normal.Undercharge symptoms: Long run time, poor cooling anda hot compressor dome are the main symptoms of anundercharge.Beverage-AirRev. 10/20
