Function Description
The Majestic Milk Dispensers are designed to store and dispense milk, maintaining it at a safe and appropriate temperature. These units are self-contained, refrigerated appliances intended for commercial use, specifically in foodservice settings. They are built to provide a reliable and efficient solution for dispensing milk, ensuring product quality and safety. The dispensers are equipped with features that facilitate easy operation and maintenance, making them suitable for environments requiring consistent milk service.
Important Technical Specifications
The Majestic Milk Dispensers are available in various models, each identified by a specific SKU. While detailed individual specifications for each model (e.g., capacity, dimensions, power consumption) are not explicitly listed in the provided excerpts, the manual implies a range of configurations to suit different operational needs. The units are designed to operate with a specific refrigerant, R290, which is a flammable refrigerant. This necessitates strict adherence to safety precautions during installation, servicing, and disposal.
Key electrical specifications include:
- Power Cord: The units are designed for either 115V/60Hz or 230V/50-60Hz electrical supplies, depending on the model and regional requirements.
- Compressor: The compressor is a critical component for refrigeration, and its specifications (e.g., 115V or 230V) are tied to the overall electrical configuration.
- Thermistors: The manual includes a detailed section on thermistor field testing, indicating the presence of multiple thermistors (e.g., 60" black, 120" black, 60" green, 120" green, 96" black) for accurate temperature monitoring within the unit. These thermistors are crucial for maintaining the desired internal temperature and ensuring food safety.
The construction of the cabinet is designed for durability and hygiene, featuring a stainless steel exterior and a plastic covering for protection during manufacturing and shipping. The interior and exterior surfaces are designed to be easily cleaned.
Usage Features
The Majestic Milk Dispensers are designed for straightforward operation and ease of use in a commercial environment.
Installation:
- Placement: The unit must be placed on a counter capable of supporting a minimum of 300 pounds. For wall-mounted units, a wall mounting kit is required.
- Leveling: The unit must be level, with the front legs adjustable to aid in leveling.
- Electrical Connection: The dispenser requires a dedicated electrical circuit with a 15 or 20 ampere fuse or breaker. It is crucial to ensure the power cord is properly grounded.
- Drip Tray: The drip tray must be installed correctly to collect any spills during dispensing.
Operation:
- Initial Startup: After installation, the unit should be allowed to run for a minimum of two hours before loading with product to ensure proper cooling.
- Temperature Control: The unit features a temperature control system that allows for adjustment to maintain the desired milk temperature. The manual provides instructions on how to set the temperature and adjust the control setting.
- Milk Loading: The milk is loaded into the dispenser, typically through a valve system. The manual emphasizes the importance of proper valve installation and adjustment to prevent leaks.
Maintenance Features
Regular maintenance is crucial for the longevity and efficient operation of the Majestic Milk Dispensers. The manual outlines several key maintenance procedures.
Cleaning:
- General Cleaning: The stainless steel exterior and interior surfaces should be cleaned periodically with a solution of warm water and mild soap. A soft cloth or sponge should be used, followed by rinsing with clean water and wiping dry. A stainless steel cleaner can also be used.
- Drip Tray Cleaning: The drip tray should be regularly cleaned to prevent buildup.
- Valve Cleaning: The milk valve system requires regular cleaning to prevent milk residue buildup and ensure proper dispensing. The manual provides detailed instructions for disassembling, cleaning, and reassembling the valve components.
- Defrost: The unit features a manual defrost unit. The manual provides instructions on how to defrost the unit, emphasizing the importance of removing all milk products and cleaning the interior after defrosting.
Refrigeration System Maintenance:
- Refrigerant Handling: Due to the use of R290 flammable refrigerant, all maintenance involving the refrigeration system must be performed by qualified personnel. This includes checks for leaks, repairs, and charging procedures.
- Leak Detection: Regular leak detection is critical. The manual specifies using an electronic leak detector or soap/water solution for detection.
- Servicing: Any repairs or servicing of the refrigeration system, including compressor work, must be done by trained service personnel to prevent injury or equipment damage. The manual provides guidelines for servicing R290 refrigerant systems, including procedures for checking for presence of refrigerant, information on servicing, and general work area requirements.
- Electrical Checks: Regular checks of electrical components are recommended to ensure proper functioning and safety. This includes verifying wiring, connections, and the condition of electrical components.
Troubleshooting:
- Thermistor Field Testing: The manual includes a detailed guide for testing thermistors using a multimeter, providing a table of resistance values at different temperatures to aid in diagnosis. This allows technicians to verify the accuracy of temperature readings and identify faulty thermistors.
- Replacement Parts: The manual provides a comprehensive list of replacement parts, including part numbers, to facilitate ordering and ensure the use of genuine Silver King components.
Warranty Information:
Silver King provides a warranty that covers defects in material and workmanship. The warranty period varies for different components, with a one-year labor warranty, five-year compressor warranty, and a three-year hinge and handle warranty. The warranty terms emphasize that repairs must be performed by authorized service personnel and that the use of non-OEM parts may void the warranty.
Safety Precautions:
The manual includes extensive safety precautions, particularly concerning the flammable R290 refrigerant. These warnings highlight the risks of fire, explosion, and injury if proper procedures are not followed. It is crucial to read and understand all safety warnings before operating or servicing the dispenser. This includes warnings about electrical hazards, proper ventilation, and the handling of flammable substances.
