The location of the Hi-Limit Sensor element is at the supply duct louver and has been
chosen to supervise that temperature. The Hi-Limit instrument should be set
approximately 10 to 20 degrees F., higher than the maximum operating temperature. This
setting will eliminate nuisance shutdowns when operating at the maximum temperature
of the unit and still give maximum protection to the oven or furnace
DESPATCH INDUSTRIES CANNOT BE RESPONSIBLE FOR EITHER
THE PROCESS OR THE QUALITY OF THE PRODUCT BEING
PROCESSED.
If the product on which the equipment is being used is critical of over temperature the Hi-
Limit should be used as a "Process Hi-Limit.” The sensor element is located on the
supply duct where the hot air enters work chamber. The temperature setting on the
“Process Hi-Limit” should be set somewhat below the temperature at which the product
would be damaged. If the product has an ignition temperature at which it could ignite, the
setting should be well below this temperature. It is recommended that a certified
instrument be used to make the proper setting.
IT IS THE PURCHASER'S RESPONSIBILITY THAT THE “EQUIPMENT
HI-LIMIT" AND/OR THE “PROCESS HI-LIMIT” BE SET PER THE
INSTRUCTIONS ON THIS SHEET AND ALSO THE INSTRUCTION
SHEET FOR THE PARTICULAR HI-LIMIT INSTRUMENT FURNISHED
