8.) GENERAL INFORMATION FOR TEST FRAME OVENS CAUTION! Failure to check thermocouple wiring and connection before initial start up could result in damage to the oven. INSPECTION Carefully inspect the oven upon its arrival for possible damage incurred during shipment. If damage is evident, immediately notify the carrier and file a claim.
Page 12 MOUNTING All ovens are supplied with slide mounting brackets. Before moving the oven, make sure the locking pins are engaged to prevent the slides from moving. The oven should only be moved via an overhead crane or fork truck using the supplied eyebolts on the top of the oven.
Page 13 OPERATION The conduit is permanently secured and the rear cover installed, apply power to the control system to test the oven's components. Then run the oven up to 200F to verify proper operation. CAUTION: Do not run up to maximum operating temperature until the control thermocouple has been positioned properly.
Page 14 AIR FLOW PATTERN An Oven Air Flow Pattern drawing for this oven is included in this manual. The exhaust is top and bottom with the inlet in the middle. The main plenum protects the working chamber from direct radiation from the heating elements. The secondary plenum adds turbulence and prevents the air from directly recirculating.

Page 18: Thermocouple
10.) THERMOCOUPLE A thermocouple is used to measure the voltage that is generated as the temperature increases. It provides an input signal for the control system that monitors the temperature of the heated chamber. At high temperatures, the elements within the thermocouple may undergo some oxidation or corrosion causing the signals to be read incorrectly by the control system.
Page 19 11.) ENABLING THE COOLING FUNCTION Thermcraft, Inc. does not enable the cooling function of your oven prior to shipment. Following are instructions to do so. To enable output 2A, access the configuration mode. Put in code, if any. Default is 2.
