5.

To test the heating up time:  Close the Oven Door (6) and close the Adjustable Vent (7)
located on the side of the Oven.  Turn the Thermostat to its ON position and set the
Thermostat for 450 degrees.  To test the heating up time (also called the “bring up time”)
simply observe the Thermostat (5) and use a watch (not included) to record the time it
takes for the Oven to reach a desired temperature.

6.

To test the temperature drift: Close the Oven Door (6) and close the Adjustable Vent (7).
Turn the Thermostat to the ON position and set the Thermostat at 450 degrees.  To test the
temperature drift (any variation in the preset temperature), the reading on the Thermometer
should be recorded once every hour for a period of eight hours.  The temperature drift
should not or - 10 degrees.  If the temperature drift e or - 10 degrees, a
qualified technician should check the Thermostat (3).

7.

To test the temperature recovery time:  A thermometer (not provided) which is of a
commercial grade, and previously tested and approved, should be placed in the center of the
Oven floor.  Close the Oven Door and close the Adjustable Vent (7).  Turn the Thermostat to
450 and allow sufficient time for the Oven temperature to reach 450 degrees.  Open the
Oven Door and leave the Door open for exactly one minute.  Then, close the Oven Door and
observe the Thermometer.  Within thirty minutes after the Oven Door has been closed the
Thermometer should read 450 degrees.  If the temperature recovery time does not reach 450
degrees within 30 minutes, a qualified technician should check the Oven for proper
functioning.

8.

To test for temperature overshoot:  Place a thermometer (not included) in the center of the
Oven floor.  Close the Oven Door (6) and close the Adjustable Vent (7).  Set the Thermostat
to any temperature up to 480 degrees.  Every five minutes record the temperature reading on
the thermometer.  Note the point at which the degree reading approaches, settles and does
not fluctuate.  The maximum temperature recorded should not exceed ten degrees
Fahrenheit over the number of degrees the Thermostat is set at.  If the temperature
overshoot exceeds ten degrees, a qualified service technician should check the Thermostat
(5) and Oven for proper functioning.

To clean:

Wipe with a damp cloth, using a mild detergent or mild solvent.  Do not use cleaners
that are combustible or corrosive.
