Need help?Do you have a question about the Beverage-Air HFS3HC-1S and is the answer not in the manual?
The Beverage-Air HF Freezer is a commercial food service equipment designed for use in bars and restaurants, providing reliable freezing capabilities for various food products. This appliance is engineered with a focus on quality and durability, aiming to offer years of trouble-free operation when properly maintained.
The HF Freezer's primary function is to maintain internal temperatures suitable for freezing food, typically set at 0°F (with a range between 2.5°F and -2.5°F as shipped), and adjustable down to -10°F. The unit operates by continuously monitoring the air temperature at the return air probe. When the internal temperature rises above the set point plus 2.5°F, the compressor and condenser fan activate to cool the cabinet. The evaporator fan also runs when the compressor is active and the doors are closed, ensuring efficient air circulation within the cabinet.
Defrost cycles are automatically initiated based on cumulative compressor runtime, typically after 6 hours, or when the temperature at the defrost probe drops too low. During defrost, the defrost heater activates to melt any accumulated ice, and the compressor and fans temporarily cease operation. The unit is designed to automatically revert to normal operation once the defrost cycle is complete or the temperature at the defrost probe reaches the defrost termination temperature.
For models equipped with glass doors, an internal light can be toggled on or off by pressing the "SC" button on the electronic controller. For solid door models, the light automatically turns on when the door is opened. The electronic controller, a Danfoss ERC 112D or ERC 112C, serves as the central control interface, displaying the current cabinet temperature and allowing for set point adjustments. It also provides visual indicators and messages for various operational states, such as defrosting, high temperature, open door, or sensor failures.
The refrigeration system utilizes R290 refrigerant, a flammable substance, which necessitates specific safety protocols for service and maintenance. The unit is cord-connected and requires a dedicated 115-volt, 60 Hz AC electrical circuit, using either a 5-15P or 5-20P plug depending on the model. It is crucial to connect the unit to a properly grounded outlet and avoid using extension cords or GFI/GFCI outlets, as these can lead to product loss due to unsafe cabinet temperatures if the device trips.
The HF Freezer is designed for straightforward operation. Once connected to the correct power supply, the unit will automatically begin to cool. The electronic controller displays the current internal temperature, and while the set temperature can be adjusted, lowering it will not accelerate the cooling process; the refrigeration system always operates at maximum capacity when active.
The controller features a user-friendly interface with UP/DOWN buttons for adjusting the set point, a DEFROST (ESC) button for manual defrost or entering standby mode, and a SELECT (OK) button for toggling lights or switching between Fahrenheit and Celsius display. Various LED indicators on the control panel provide quick visual feedback on the unit's status, including defrost activity, fan operation, alarm conditions, and compressor status.
The unit is equipped with shelves that can be installed at desired locations using shelf clips. Proper installation of these clips and shelves is essential to ensure stability and prevent damage or injury. The product retention bar on the shelves should face up. It is important not to overload the shelves, as the unit is designed to accommodate all supplied shelves in an equally spaced manner.
Door reversal instructions are provided, allowing users to change the door's swing direction if needed. This involves removing hinge covers, brackets, and hole plugs, rotating hinge components, and reinstalling them in the desired configuration.
Regular maintenance is crucial for the optimal performance and longevity of the HF Freezer. The manual outlines a comprehensive cleaning schedule and specific procedures for various components.
The manual provides a detailed table for cleaning various types of stains and discolorations on stainless steel, recommending specific cleaning agents and application methods to maintain the finish. This includes solutions for smears, fingerprints, stubborn spots, heat tint, burnt-on foods, tenacious deposits, and hard water spots.
A trouble diagnosis section helps users identify and resolve common issues, such as no cooling, unit running constantly, or temperature problems. It provides possible causes and likely solutions, distinguishing between user-addressable issues and those requiring a technician.
For service technicians, the manual emphasizes that refrigeration service should only be performed by trained professionals certified to work on R290 systems due to the flammable nature of the refrigerant. Critical service items include avoiding wire nuts for electrical parts, using only exact replacement switches, using process tubes for service access, cutting (not un-brazing) refrigeration components, venting R290 in well-ventilated areas free from flames, attaching a sign noting propane presence during service, and using a combustible gas leak detector. Proper evacuation and critical charging by weight are also highlighted as essential for R290 systems.
