RAD Oven Series Owner’s Manual Version 1 ABOUT THIS MANUAL 11 1.5.4. Power Line voltages may vary in some geographies. If the line voltage for your RAD oven varies more than 10% from the oven voltage rating, electrical components such as relays and temperature controls may operate erratically. If the line voltage is lower than the oven voltage rating, heat-up time may be significantly longer and motors may overload or run hot.
RAD Oven Series Owner’s Manual Version 1 SAFETY 12 2. Safety 2.1. Safety Information Do not work on the RAD oven without reading and understanding this section which contains important information and warnings. Ignoring these warnings can result in death, serious injury or damage to the machine and product. 2.1.1. Lockout Machine lockout places the RAD oven into a zero energy state and prevents accidental machine start up.
RAD Oven Series Owner’s Manual Version 1 2.2. Maintenance Only qualified and trained personnel should perform maintenance or repair. 2.3. Electrical Power Only qualified and trained personnel should perform electrical maintenance or electrical repair. Danger! High voltage present on this equipment, service by authorized personnel only. Contact with energized electrical sources may result in serious injury or death. Before performing maintenance, disconnect all electrical power from the machine.
RAD Oven Series Owner’s Manual Version 1 SAFETY 14 2.5.1. Optional Disconnect Switch The RAD oven has an optional Disconnect Switch (Figure 3). This Disconnect Switch is connected to the load break switch behind the panel that disconnects or connects power from the main line. When a risk of personal injury or damage to the RAD oven exists, turn OFF the DISCONNECT SWITCH on the front of the oven. This shuts off all electrical power to the oven. Figure 3. Disconnect Switch.
RAD Oven Series Owner’s Manual Version 1 3. THEORY OF OPERATION 15 Theory of Operation 3.1. The RAD Oven Series The RAD ovens (Figure 4) feature horizontal recirculating airflow to ensure exceptional temperature uniformity throughout the oven. A high-volume fan circulates air through perforated, stainless steel walls to create a constant horizontal airflow across all sections of the oven.
THEORY OF OPERATION 16 RAD Oven Series Owner’s Manual Version 1 Table 1. Damper Positions for Chamber Pressure. Damper Fresh Air Open Exhaust Closed Chamber Pressure Positive Position Closed Open Negative Warning! Maintain slight positive pressure to regulate heat. Too much positive pressure in an oven can create a high outer skin temperature as hot air is forced out through panel joints and around door seal. High outer skin temperature could warp the front of the oven. 3.2.1.
RAD Oven Series Owner’s Manual Version 1 THEORY OF OPERATION 17 The chamber cannot readily dissipate heat generated by friction without a fully open fresh air damper. With the fresh air damper fully open, the thermal equilibrium temperature is the minimum operating temperature of the chamber. When the damper is in full open position, the oven may not be able to heat to the maximum oven operating temperature. 3.2.1.3.
THEORY OF OPERATION 18 RAD Oven Series Owner’s Manual Version 1 Figure 8. Initial factory settings for optional louvers. 3.3.1. Purpose of Adjustable Airflow Optional adjustable airflow has several purposes in the RAD oven: 1. Ability to get the best temperature and airflow uniformity. 2. Ability to “spot heat” special areas or specific parts of load. 3. Ability to prevent air flowing out or sucking in through the entrance and exit openings in the oven. 3.3.2.
RAD Oven Series Owner’s Manual Version 1 THEORY OF OPERATION 19 3.4. The Protocol 3 Controller Notice It is particularly important that the oven operators have a practical understanding of the automatic controls. These regulate the temperature, provide safety features and generally govern the consistently uniform and satisfactory performance of the oven. The Protocol 3™ is a microprocessor based digital temperature controller designed for simple and flexible oven operation (Figure 9).
THEORY OF OPERATION 20 RAD Oven Series Owner’s Manual Version 1 Figure 9. Protocol 3 Operator Interface. 3.5. Optional High Limit Audible Alarm High Limit audible and visual alarm is a red light and small alarm horn located on the front of the control panel (Figure 10). The alarm is sounded if a High Limit condition occurs. A switch is provided to silence the alarm. This alarm has a range of 80dB at 2 ft (0.6 m). Figure 10. Power, Heat and Alarm Silence Switches.
RAD Oven Series Owner’s Manual Version 1 4. ASSEMBLY & SETUP 21 Assembly & Setup Assembly and Setup provides directions for unpacking and installing your RAD oven. Danger! This equipment must be installed by a licensed electrician who is experienced with combustion safeguard control systems and understands the functions of an interlocking switch such as gas pressure switches. 4.1.
ASSEMBLY & SETUP 22 RAD Oven Series Owner’s Manual Version 1 Warning! Do not use the oven in wet, corrosive or explosive atmospheres unless this oven is specifically designed for a special atmosphere. Notice 4.2.1.1. Review oven weight to ensure the foundation is adequate to hold the weight. Placement Requirements Place oven directly on the floor. Plumb and level the oven to assure proper heat distribution and operation of all mechanical components.
RAD Oven Series Owner’s Manual Version 1 ASSEMBLY & SETUP 23 4.3.1. Down Drafts Where down drafts occur in gravity stacks, their cause should be determined and corrections made without delay. They can cause concentrations of exhaust volatiles within the work chamber, poorly baked products, poor burner operation or the spreading of odors into the factory.
OPERATION 24 5. RAD Oven Series Owner’s Manual Version 1 Operation Users and operators of this oven must comply with operating procedures and training of operating personnel as required by the Occupational Safety and Health Act (OSHA) of 1970, Section 5 and relevant safety standards, and other safety rules and regulations of state and local governments. Refer to the relevant safety standards in OSHA and National Fire Protection Association (NFPA), Section 86 of 1985.
RAD Oven Series Owner’s Manual Version 1 OPERATION 25 The two shelves are designed to be pulled out about halfway without tipping. Do not overload the shelves. Shelf support capacity is listed in the Capacities section (1.5.2). Do not overfill the oven. Distribute the workload evenly so airflow is not restricted. The workload should not take up more than two-thirds of any dimension of the inside cavity. For best results: Do not place the load within 7.62cm (3 inches) of louvers or within 15.
OPERATION 26 RAD Oven Series Owner’s Manual Version 1 If polarity is reversed during wiring, the fan will rotate backwards and compromise proper ventilation. Check fan rotation after the initial installation and after reconnecting the power supply to ensure fans are running in the correct direction. To check fan rotation: 1. Momentarily toggle POWER (Figure 10) to start fans and check rotation. 2. Rotation should correspond to the directional arrows provided. 3. Reverse motor rotation where necessary.
