RFD 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 RFD oven varies more than 10% from the oven voltage rating, electrical components such as relays and temperature controls may operate erratically.
RFD Oven Series Owner’s Manual Version 1 ABOUT THIS MANUAL 12 1.5.5. Capability The RFD oven is specifically designed for Class A NFPA 86 requirements, in which flammable solvents are present. They include a pressure relief panel, purge timer and exhaust fan. Please note the solvent handling capabilities and do not exceed. Danger! Class A ovens are designed for a specific amount of solvent. Exceeding this amount could result in an explosion. Refer to Design Specification Label (Figure 14) or Section 1.
RFD Oven Series Owner’s Manual Version 1 2. Safety 2.1. Safety Information Do not work on the RFD 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 RFD oven into a zero energy state and prevents accidental machine start up.
RFD Oven Series Owner’s Manual Version 1 SAFETY 14 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.
RFD Oven Series Owner’s Manual Version 1 SAFETY 15 2.5.1. Optional Disconnect Switch The RFD 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 RFD 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.
RFD Oven Series Owner’s Manual Version 1 THEORY OF OPERATION 16 3. Theory of Operation 3.1. The RFD Oven Series Despatch RFD ovens 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.
RFD Oven Series Owner’s Manual Version 1 THEORY OF OPERATION 17 3.2. Damper Control The RFD Series oven includes a manually adjustable fresh air damper mechanism which controls the flow of fresh air into the chamber. The fresh air damper control is located on the left side of the oven (Figure 5 and Figure 6). The oven also includes a manually adjustable exhaust damper located on the exhaust stack on top of the oven (Figure 6).
RFD Oven Series Owner’s Manual Version 1 THEORY OF OPERATION 18 3.2.1. Determining Damper Settings The optimum setting for the amount of fresh air that should be distributed into the chamber depends on several factors. These factors include ambient environment temperature, load conditions, load distribution, heat-up rates, cool-down rates, desired temperature uniformity and, most importantly, the desired operating temperature.
RFD Oven Series Owner’s Manual Version 1 THEORY OF OPERATION 19 3.3. Optional Adjustable Louvers This section applies only to ovens that include the optional adjustable louvers. Ovens without the louver option do not have adjustable airflow. RFD oven series come standard with perforated supply and exhaust panels (Figure 7). Optional adjustable louvers provide an extra measure of airflow customization (Figure 7). Figure 7 shows the initial factory settings for the optional louvers.
RFD Oven Series Owner’s Manual Version 1 THEORY OF OPERATION 20 3.3.1. Purpose of Adjustable Airflow Optional adjustable airflow has several purposes in the RFD 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.
RFD Oven Series Owner’s Manual Version 1 THEORY OF OPERATION 21 controller/High Limit instrument. The control portion utilizes a time proportioning voltage signal to control heating devices with minimal temperature fluctuations. The High Limit portion protects the product and/or the oven from overheating. If the product being processed has a critical high temperature limit, the High Limit setpoint should be set to a temperature somewhat below the temperature at which the product could be damaged.
RFD Oven Series Owner’s Manual Version 1 THEORY OF OPERATION 22 3.5. Optional High Limit Audible Alarm High Limit audible and visual alarm is a red light (Figure 13) and small alarm horn located on the front of the control panel. 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). 3.6.
RFD Oven Series Owner’s Manual Version 1 4. ASSEMBLY & SETUP 23 Assembly & Setup Assembly and Setup provides directions for unpacking and installing your RFD 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.
RFD Oven Series Owner’s Manual Version 1 ASSEMBLY & SETUP 24 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. Allow adequate clearance for explosion relief. Minimum clearance for explosion relief is 18 in. above the oven.
RFD Oven Series Owner’s Manual Version 1 Notice ASSEMBLY & SETUP 25 Flashing through roof or wall must be capable of handling temperatures up to 343°C (650°F). All stacks must comply with state and local building codes to ensure that surrounding combustible surfaces are below 71°C (160°F). 4.4. Wiring & Power Connections See electrical schematics in Section 8.3 for line connections. The oven must be hardwired directly to the electric supply.
RFD Oven Series Owner’s Manual Version 1 OPERATION 26 5. 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.
RFD Oven Series Owner’s Manual Version 1 OPERATION 27 Caution! Always place loads on the shelves provided to avoid possible uneven heating and damage to the oven. 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.
RFD Oven Series Owner’s Manual Version 1 OPERATION 28 5.3. Operating Procedure 5.3.1. Check Fan Rotation and Other Preliminaries If polarity is reversed during wiring, the fan will rotate backwards and compromise proper ventilation. 1. Check fan rotation after the initial installation and after reconnecting the power supply to ensure the fans are running in the correct direction. To check fan rotation: a. Momentarily toggle POWER (Figure 13) to start fans and check rotation. b.
RFD Oven Series Owner’s Manual Version 1 OPERATION 29 Never operate oven at a temperature above the maximum operating temperature: 343°C (650°F) 5.3.2. Start and Operate the Oven 1. Set the main Power Disconnect switch to ON (Figure 3). 2. Set POWER to ON. The recirculation fan will start, and the purge timer will begin timing. Notice The heater of the Class A oven cannot be energized until the forced exhaust system has brought in a minimum amount of fresh air into the chamber.
