The provided document is a product manual for the BAR3 Shelf Mounted Beer Coolers, manufactured by Booth Dispensers Ltd. The manual covers various aspects of the device, including its introduction, safety guidelines, specifications, installation instructions, model numbering convention, schematics, fault finding, spare parts, and removal/transportation/disposal procedures.
Function Description
The BAR3 is an ice bath cooler designed to provide chilled product in a dispense application. It utilizes a bath water recirculation system and python to generate and maintain optimum drink temperature at the point of dispense. The cooler is designed for effective performance and improved energy efficiency, making it suitable for a range of applications, particularly under-counter installations due to its compact size.

Usage Features
The BAR3 cooler is designed for straightforward operation once installed.
- Chilling Mechanism: It uses an ice bank system where water in the bath is chilled to form an ice bank, which then maintains the desired temperature for the dispensed product.
- Recirculation System: A bath water recirculation system works in conjunction with a python to ensure optimal drink temperature at the point of dispense.
- Compact Design: Its compact size makes it ideally suited for under-counter installations, saving valuable space in dispense environments.
- Model Numbering Convention: A detailed convention allows for easy identification of specific unit configurations, including refrigerant type (Z), pump type (Y), module type (X), deck configuration (W), and number of coils (V). This modularity allows for customization based on specific dispense needs.
- Refrigerant Type (Z): 0 for R134a, H for R290 (Hydrocarbon).
- Pump Type (Y): Options include SPC8/2, SPC12/4, Saber Pump Assy (for BAR3H and BAR300).
- Module Type (X): Mechanical Control, Eliwell Control, DFX Control.
- Deck (W): No Coils, 1 Coil, 2 Coils, 3 Coils, 4 Coils, or Tube in Tube / Scope.
- Number of Coils (V): Indicates the quantity of coils, repeated as necessary for specific configurations.
Maintenance Features
The manual provides clear guidelines for installation, fault finding, and spare parts, which are crucial for maintaining the device.
Installation:
- Level Surface: Must be installed on a firm, level surface capable of supporting the machine's weight when the bath is filled.
- Ventilation: Ensure ventilation openings are not blocked, maintaining at least a 100mm gap between the appliance and any obstructions. Failure to do so can affect reliability, invalidate warranty, and shorten the system's life.
- Water Bath Filling: The water bath must be filled with cold water through the top opening until water is displaced from the overflow, prior to switching on.
- Connections: Connect the dispense python to the 'Recirculation' Flow and Return, and the product to the stainless steel product coil.
- Power-Up Sequence: After connecting to mains power and switching on, the compressor fans will activate after a short delay, and the unit will begin to reduce bath water temperature. The bath level should be monitored and topped up as the python fills. An ice bank will form once the water reaches the correct temperature, displacing a small amount of water. The fans and compressor will switch off once a full ice bank is produced, indicating readiness for use.
Safety:
- Qualified Service: Service must only be carried out by a suitably qualified refrigeration engineer.
- Electrical Isolation: The unit must be isolated from the electricity supply before removing covers.
- Refrigeration Circuit: Do not damage the refrigeration circuit.
- Component Replacement: Where electrical components are replaced, the new component must be of the same type.
Fault Finding:
The manual includes a comprehensive fault-finding guide to diagnose common issues:
- No Drinks: Check water supply connections, ensure water supply is on, and check for system blockages.
- Frozen Product Coil: Verify thermostat/temperature probe location, check agitator operation (if agitator is not running but supply voltage is present, renew agitator assembly; if running but no water agitation, check blades).
- Warm Drinks: Check for insufficient air flow, blocked condenser, and obstructions to ventilation grills.
- Cooling Fans Not Running: Check supply to fans (if supply present, replace fans; if not, check connections, thermostat, high side protection, and fuse).
- Compressor Not Running: Check supply to compressor (if supply present, return for repair; if not, check connections, thermostat, high side protection, and fuse).
- Fridge Failure: If compressor and fan are running but no cooling, return for repair.
Spare Parts:
Detailed diagrams and part numbers are provided for key components for both BAR300 and BAR3H models:
- Control Modules: Eliwell Control Module (1A5362), DFX Control Module (1A6310), Mechanical Control Module (1A5361).
- Cooling Fan: 1B5514.
- Pumps: Specific pump part numbers are referenced in the model numbering table on page 5.
- BAR3H Specific Parts: Polar Clean Elbow (INSU77), Coaxial Elbow (3B6090).
Removal, Transportation, and Disposal:
- Disconnection: All electrical, product, and gas connections must be disconnected before removal.
- Scrap Units: It is illegal to simply scrap a refrigeration unit; gas must be removed by a specialist. Booth Dispensers Ltd. can provide a quotation for disposal.
- Transportation: The unit must be transported in an upright position to prevent irreparable damage to the refrigeration system. If transported incorrectly, it should be placed upright for 24 hours before running. Failure to observe these precautions will damage the system and void the warranty.
The manual also includes detailed schematics for Eliwell, DFX, and Mechanical wiring configurations for both BAR3H and BAR300 models, aiding in troubleshooting and maintenance.
