5 PROCESSING
5-1 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. Special
consideration should be made for the potential of smoke damage should a fire
ensue. Fire suppression equipment should be installed to protect the oven and
building. Excess temperature limit interlock should be connected to the building
alarm system.
5-2 When loading an oven care must be taken to avoid touching or insulating the
thermocouple or temperature sensor. Free air movement around this sensor is
essential for safe and correct temperature control.
5-3 Do not overload the oven. Air circulation is very important to the proper operation of
an oven.
5-3.1 Ovens designed for shelf loading should not have parts placed on floor of work
space. This surface is not designed to support a load.
5-3.2 Leave space between articles on each shelf to allow air to move between parts.
5-3.3 Parts should be staggered from one shelf to another, to prevent dead spots in the
air pattern.
5-4 To turn oven on, push top of on-off switch in. When the oven is not in use, the on-off
switch must be turned OFF - bottom pushed in. Do not rely on the thermostat to
interrupt power to the heating elements indefinitely.
5-5 Set desired operating temperature on temperature controller; Refer to controller
instructions included.
5-6 EMERGENCY SHUT DOWN:
-press power switch to "OFF" - bottom pushed in
-unplug oven
