Page 4: Proper Oven Application
2 PROPER OVEN APPLICATION GENERAL 2-1.1 W hile ovens are extremely versatile, they are usually purchased with a specific application in mind. If your process has changed significantly or if you should have reason to doubt that a specific application is a proper use of the equipment, consult the factory before proceeding. -
Page 5: Combustible Material
COMBUSTIBLE MATERIAL 2-3.1 Introduction of combustible materials (such as paper, cardboard or wood) into the oven should be avoided because it might cause a fire. Do not use combustible racks, trays, holders, spacers, etc. Periodically, clean all combustible material from non-combustible racks, trays, holders, spacers, etc. If combustible products must be processed in an oven, extreme care must be taken to ensure that the operating temperature does not exceed the ignition temperature of the product. -
Page 6: Maintenance And Inspection
MAINTENANCE AND INSPECTION 2-5.1 Regularly scheduled inspection and maintenance of all safety devices shall be performed by user. Failure to do this may result not only in fire or explosion damage, but also contribute to accidental shutdowns and loss of production. See Section 7 - AMaintenance@ and Appendix B - AMinimum Periodic Maintenance Report@. -
Page 7: Installation
INSTALLATION LOCATION 3-1.1 Ovens shall be located to protect them from damage by external heat, vibration and mechanical hazards. 3-1.2 Ovens shall be located to minimize exposure to power equipment, process equipment and sprinkler risers. Unrelated stock and combustible materials shall be maintained at a fire-safe distance but not less than 2-1/2 feet from an oven or ductwork. -
Page 8: Ventilation
3-3.3 Do not store material on top of oven. The oven is not designed to carry exterior loads. Also, material may get hot, ignite and cause a fire. 3-3.4 The oven doors have spring loaded latches which will allow the doors to open if pressure develops in the oven. -
Page 9: Thermometer
THERMOMETER 3-6.1 On all standard models a dial thermometer is included. Insert it into its spring steel holder so that it extends at least three inches (3") into oven work space. thermometer can be installed through any of the vent ports in the top of the oven. ELECTRICAL 3-7.1 All electrical connections should be made in accordance with the appropriate local... -
Page 10: Prior To Placing Oven In Service
PRIOR TO PLACING THE OVEN IN SERVICE Read instruction manual completely. After the installation is completed, replace all covers and guards that had been removed for installation. At no time should equipment be operated if covers or guards are open, removed or partially closed. Check incoming voltage against that shown on the nameplate. -
Page 11: Processing
PROCESSING DO NOT LEAVE THIS EQUIPMENT IN OPERATION UNATTENDED W hen using any heat processing equipment there is always the risk of overheating due to a component malfunction. A trained operator should always be present. If this is not possible, the oven should be located where overheating will not cause damage to the building, adjacent stock or endanger personnel. - Page 12 5-11 TEMPERATURE CONTROL 5-11.1 The thermostat is marked with numbers for reference only and does NOT indicate the oven temperature. To obtain the desired temperature, make a trial setting of the thermostat and observe the actual oven temperature as shown by the thermometer.

Page 13: Safety Equipment
Do not remove or bypass excess temperature limit interlock. 6-5.1 One-time excess temperature limit interlock (standard on Models LO-201C and LW -201C) is installed in series with the oven thermostat. If the oven runs over maximum temperature, the excess temperature limit interlock will open the circuit to the heating elements. -
Page 14: Maintenance
7 MAINTENANCE For safe oven operation, a preventative maintenance program must be developed and followed for each individual oven application. The user should review recommendations from their insurance underwriters. W e suggest the review of Factory Mutual (FM) Specification 6-9 on Industrial Ovens and Dryers and the National Fire Protection Association (NFPA) Specification 86 on Ovens and Furnaces. - Page 15 7-4.3 Oven Body 7-4.3.1 Do not allow accumulation of combustible material or other foreign matter in the work space, heat chamber (including heating elements) ductwork, air inlets, vent outlets, control enclosures, door latches, and door hinges. Care must be taken in cleaning any combustible build-up to avoid creating a source of ignition (spark).
- Page 16 7-4.7.2 Processes involving flammable liquids or creating explosive vapor or combustible dust clouds must not be located near the oven. 7-4.7.3 Portable fire extinguishers located in the vicinity of the oven must be inspected periodically. 7-4.7.4 Fire suppression system installed in the oven should be periodically tested. All sprinkler heads in oven or located in work area should be periodically inspected and cleaned.

Page 17: Trouble Shooting
8-1.1 Oven Has Run Over-temperature. For Model LO-201C and LW -201C, check continuity of heat limiter (one time thermal fuse) and replace it if there is no continuity through the heat limiter. Heat limiter is located in one of the wires leading to the thermostat. This wire is covered with a radiant shield that must cover the heat limiter for correct operation. - Page 18 W IRING DIAGRAMS: Do not operate oven without a functioning heat limiter or manual reset excess temperature interlock. Do not bypass or otherwise defeat the heat limiter or manual reset excess temperature interlock. 18 of 23 07/18 LABO VEN S.IN S.7-18.wpd...
