The Orford EB Series Vertical Refrigerators are a range of 1, 2, and 3 door bottom-mount display and storage refrigerators designed for commercial use. These appliances utilize energy management technology to maximize energy savings and are available in various models, including EB20R-B, EB20R-Sn-B, EB30R-B, EB30R-Sn-B, EB36R-B, EB36R-Sn-B, EB45R-B, and EB45R-Sn-B.
Function Description:
The primary function of the EB Series Vertical Refrigerators is to provide refrigerated storage and display for perishable goods in commercial environments. They are equipped with an Energy Management System (EMS) controller that automatically learns the operation patterns of the premises using door and motion sensors. During the initial 7-day learning period, the product temperature remains constant, and lighting runs continuously (unless overridden by manual switches). After this period, the control automatically switches off interior and sign lights when the premises are closed, optimizing energy consumption. The system continuously learns and adapts to changes in operating times. The product temperature remains unchanged when set to "Perishable Mode," which is the factory default setting. An "Energy Saving Stand-by Mode" is also available with prior arrangements.
Important Technical Specifications:
The EB Series refrigerators are designed to operate within specific climate classes, which define the suitable ambient conditions.
- Climate Class:
- EB20R, EB30R, EB36R models: Climate Class 5 (Ambient Temperature 40°C, Ambient Humidity 40% RH)
- EB45R models: Climate Class 4 (Ambient Temperature 30°C, Ambient Humidity 55% RH)
- Power Requirements: All models require a 230-240V, 50Hz power supply and are designed for a standard 10 Amp power point.
- Capacities:
- EB20R-(Sn)-B: Gross Volume 595 L, Refrigerated Shelf Area 1.44 m², Total Display Area 0.68 m²
- EB30R-(Sn)-B: Gross Volume 900 L, Refrigerated Shelf Area 2.164 m², Total Display Area 0.965 m²
- EB36R-(Sn)-B: Gross Volume 1077 L, Refrigerated Shelf Area 2.614 m², Total Display Area 1.17 m²
- EB45R-(Sn)-B: Gross Volume 1407 L, Refrigerated Shelf Area 3.4 m², Total Display Area 1.45 m²
- Lighting: All models feature LED interior lighting. Models with "Sn" in their designation also include an illuminated LED sign panel.
- Shelving: The cabinets are supplied with wire shelving, each requiring 4 shelf clips. The maximum load per shelf is 40kg, evenly distributed. The bottom shelves are crucial for maintaining correct product temperatures and catching spills, and must be fitted in their correct position while the refrigerator is in use.
Usage Features:
- Installation: Equipment should be removed from shipping blocks carefully and leveled to ensure proper door alignment and drainage. Adequate ventilation for the refrigeration unit is critical; the front ventilation grill must be kept free of obstructions. A 50mm or greater clearance from a rear wall is recommended for maximum performance and energy saving.
- Power Isolation: Power can be isolated by switching off and unplugging the appliance from the power outlet. If the outlet is inaccessible, a green illuminated switch located in the unit compartment at the bottom of the appliance can be used.
- EMS Control: The EMS3100 controller displays the refrigerator's internal temperature in "Ready Mode." LED indicators provide visual feedback on various functions:
- Motion: Flashes when motion is detected.
- Door: Illuminated when the door opens.
- Compressor: Illuminated when the compressor is running.
- Evaporator Fan: Illuminated when the evaporator fan is running at full speed.
- Bluetooth: Illuminated when a Bluetooth connection is established.
- Manual Light Switches: Two switches are provided for manual control of lighting: one for interior lighting and one for the sign (if fitted). Settings include "I" (Automatic/EMS Controlled - factory setting), "O" (Off), and "II" (On Continuously - uses more energy).
- Product Loading: Products should only be loaded within the confines of the provided shelves. The bottom shelf should be as low as possible, and no product should be stored directly on the cabinet floor to allow efficient air circulation. Shelving should not be overloaded.
- Alarms: The EMS controller provides various alarm codes to indicate potential issues:
- E1: Appliance sensor failure.
- E2: High Temperature sensor failure.
- E3: Evaporator sensor failure.
- E0: Refrigeration system failure (set point temperature not achieved within parameter CT).
- E6: Freeze up protect alarm (cooler temperature falls below parameter FU).
- EC: Door broken alarm (door not closing properly).
- ED: Door switch broken alarm (door switch not working correctly).
- EE: High temperature alarm (over-heating of refrigeration system component detected).
Maintenance Features:
- Condenser Cleaning: Regular cleaning of the refrigeration unit condenser filter is crucial for optimal performance, energy efficiency, and extended lifespan. The filter can be removed by pulling the front grill forward, lifting the filter out, brushing or vacuuming dust, and washing with clean water (detergent may be needed for grease). The filter should be drip-dried before refitting.
- Door Gaskets: Gaskets should be washed weekly with mild soap and water, followed by a fresh water rinse.
- Cabinet Interior/Exterior: The cabinet interior should be cleaned weekly with a mild solution of bicarbonate of soda and warm water. Abrasive pads should not be used.
- LED Tube Replacement:
- Recessed LED Tube: Isolate power, remove the plastic light diffuser by inserting a screwdriver at the top and lifting it out. Rotate the LED tube 90° and slide it out. When installing, lock rotating ends in the center +0° position for correct lighting direction (for single-side LED tubes only). Double-sided LED tubes do not require adjustment.
- Mullion LED Tube: Isolate power, remove the plastic light diffuser by inserting a screwdriver into the gap at the top and lifting it out. Slide it out of the mullion. Twist the LED tube 90° and slide it out.
- Note: LED lamps must be replaced with identical lamps.
- Problem Solving Checklist: A comprehensive checklist is provided to troubleshoot common issues such as the cabinet not operating, lights not working, alarms sounding, cabinet noise, doors not closing properly, temperature issues, odors, and water inside/outside the cabinet. This should be consulted before calling for service.
- Disposal: These refrigerators use flammable blowing agents for insulation and must be disposed of in accordance with government regulations.
