OPERATION
6.1 Power Supply: The power supply must be properly grounded (earthed) and
correctly sized to match the unit data plate rating. The supply voltage must match
the data plate voltage within 10%. If supplied with a detachable cord set, plug the
female end into the inlet on the unit and the male plug into the supply. Assure that
units requiring a fuse have a fuse installed.
6.2 Push the power switch to the ON position and turn the Over Temperature
Thermostat to its maximum position, clockwise so it will not interrupt the setting of
the Main Temperature control.
6.3 Place the reference thermometer through the exhaust port on top of the unit; a clip is
provided with your accessory package. See Figure 3 on the following page.
6.4 Setting Main Temperature: The operating range for this oven is ambient room
temperature + 5C to 200C. To set the Main Temperature Controller turn the knob
to the desired oven temperature, using the graduated dial as a reference guide.
Allow one hour for the temperature to stabilize. Using the reference thermometer,
verify the oven temperature; if it is not at the desired value, turn the control knob up
or down as needed. Allow the temperature to re-stabilize, continuing the process
until the exact desired temperature is achieved.
Note: Slight vapor or smoke may occur in the initial heat-up. This is a normal
occurrence when the oven is first brought up to temperature and protective
coatings on the element become hot.
6.5 Setting Over Temperature: As stated in earlier, the Thermostat should be set to its
maximum position. Now turn the control knob counterclockwise just until the
OVERTEMPERATURE ACTIVATED light comes on. Next, slowly turn the control
knob clockwise just until the light goes off. Then turn the control knob clockwise two
(2) minor scale divisions past the point where the light went out. The Over
Temperature Thermostat should now be set at approximately 10C above the Main
Temperature set point. Note that it is not recommended that the unit be allowed to
operate using the Over Temperature Thermostat as the temperature controller for
an extended period of time. See the Troubleshooting section if the Thermostat is
activated.
