OPERATION
6.1 Connection to Power Supply: Assure that the electrical power supply is properly
configured and rated for the oven and plug the unit cord into the receptacle.
6.2 Push the main power switch to the On position. The digital temperature display will
indicate a temperature value. Turn the Overtemperature Safety Thermostat to its
maximum position, clockwise using a coin or flat head screwdriver.
6.3 Set The Main Temperature Control: To enter the desired set point temperature,
press either the UP or DOWN arrow pad one time on the SET/TEMPERATURE
digital display. The display will start to blink from bright to dim. While blinking, the
display is showing the temperature set point which can be changed by pushing the
UP or DOWN arrow pads to raise or lower the value. If the arrow pads are not
pushed within five (5) seconds, the display will stop blinking and return to read the
chamber temperature. Allow several hours for the temperature to stabilize.
6.4 Calibrate The Main Temperature Control: It is recommended that display is
calibrated once the unit is installed in its working environment and has been stabile
at set point for several hours. Place a reference thermometer through the damper
tube at the top of the unit adjacent to the exhaust port. Be certain the thermometer
does not touch any shelving. Allow again for the temperature to stabilize until five
(5) consecutive readings at one minute intervals show no temperature change.
Compare the reading on the reference thermometer with the digital display. If
there is an unacceptable difference, put the display in calibrate mode by pressing
the UP and DOWN arrow pads at the same time until the decimal points blink on
and off. While blinking, the display can be changed to match the reference
thermometer by pushing the UP or DOWN arrow pads to raise or lower the
temperature until the display reads the correct value. If no arrow pads are pressed
within five (5) seconds the display will revert to displaying the temperature within
the chamber.
NOTE: Temperature accuracy should be checked at least monthly or after the unit has
been turned off for an extended period of time.
6.5 Set The Overtemperature Limit Thermostat: The Overtemperature Safety
should be initially set to its maximum position when stabilizing the set point
temperature. Once the oven is stabile at the desired set point, turn the
Overtemperature Safety counterclockwise (using a coin or flat-head screwdriver)
until the OTP light comes on. Next turn the Safety clockwise just until the OTP
light goes off. Then turn the Safety clockwise two (2) minor increments on its scale
past the point where the light went out. This sets the Overtemperature Safety
Control at approximately 10

C above the Main Temperature set point.
6.6 Set Timer Display: Turn the timer switch to the ON position. The SET/TIMER
