WARNING! This equipment is not designed for use with volatile or explosive materials unless
it is equipped with a solvent venting package or intrinsically safe interior design, and specifically
stated in your chamber specifications. Loading of such materials may result in explosion or fire.
Important! Make sure you have read (and understand) this entire manual along with all vendor manuals
enclosed before beginning oven operation.
Important! Make sure the Installation Instructions have been properly followed before operating
the oven. All switches should be in the OFF position before starting the sequence below.
Note: The sequence below was written for a standard oven. This sequence will vary slightly based on the
type of controller used, i.e., non-profiling type or profiling type.
1. Turn on the main power source to the oven along with all other utility supplies as specified in the
Installation Instructions (as applicable).
2. Turn the Main Circuit Breaker CB1001 on the front control panel to the ON position.
3. Turn the Chamber Power Switch to the ON position.
The Temperature Controller will energize and the white Chamber Power Switch light will illuminate.
When a non-profiling type temperature controller is used, the Temp Limit Controller (OTP) will also
energize, the control circuitry will be enabled, and the circulation blower will start (without a door
switch).
When a profiling type temperature controller is used, Event Output No. 1 of the controller will
automatically close to energize the Temp Limit Controller (OTP) and to enable the entire control
circuitry. The circulation blower will also start (without a door switch).
Note: The Temp Limit Controller is configured for automatic reset during a power up condition only.
This includes the return of power after a power failure.
4. Enter your temperature setpoint or temperature profile, as applicable to the controller type employed.
5. Make sure the Temp Limit Controller temperature setpoint is set approximately 11°C (20° F) above the
rated operating temperature of the oven.
6. Load product and close the oven door securely. If a door switch is employed, the circulation blower
motor will start.
7. Check for the operation of any optional equipment in the corresponding Options Section.
The following additional steps also apply when a profiling type controller is used, and with the Model
DCI as indicated.
8. Press the Program button on the profiling type controller to start the process cycle.
