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 switches to the I/On position. The digital temperature display
will indicate a temperature value. “S” suffix models require the Manual Reset
Button to be pushed. Turn the Overtemperature Safety Thermostat to its maximum
position, clockwise using a coin or a 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. When blinking in this
manner, the digital display is showing the current chamber temperature set point.
To change this set point, use 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 unit temperature. Allow several hours for the
temperature to stabilize.
6.4
Calibrate The Main Temperature Control: Temperature calibration is done once
the unit is installed in its working environment and has been stabile at set point for
several hours. 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 display blinks 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 validated with an independent thermometer at
least quarterly, or after the unit has been turned off for an extended period of time. The
calibration procedure detailed in Section 6.4 should be performed if the temperature control
is found to be inaccurate.
6.5
Set The Overtemperature Safety 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 with a flat-head screwdriver until the OTP
