LABEL OF THE CLEANER TO BE USED.
The oven should be thoroughly cleaned at least once a week in addition to
the normal daily cleaning to insure against the accumulation of foreign
material. Keep inside of oven and metal deck clean, particularly around
door opening, door edges and at bottom of door opening so that the door
may close tightly.

Any oven cleaner used should be marked: "SAFE ON
ALUMINUM".
Outside of oven and top should be kept clean.
Electric equipment is inherently clean and sanitary, but may become
unsanitary if dirt is allowed to accumulate on it. Take advantage of the
clean, sanitary features of electric equipment, give it the regular attention
that it deserves the same as any other highly perfected machinery, to insure
best results and continued high operating efficiency.
CALIBRATION
Calibration Check
Place thermometer or thermocouple in the center of oven cavity.
Set thermostat to 350° and place both 3-heat switches in the "HIGH"
position.
Allow the oven to Preheat for at least half an hour.
Note cycle on temperatures and cycle off temperatures for 3 cycles. (Red
indicator light indicates when oven is calling for heat)
After 3 cycles average the temperature. ( Add all six temperatures and
divide by 6)
Calibration Adjustment
A 1/16" flat blade screwdriver with a 2" shaft is required to make
adjustments on the thermostat.
Maintain the oven temperature at 350°.
Without turning the thermostat, remove the knob.
Locate the adjustment screw at the base of the shaft and insert the
screwdriver.
Grasp the shaft and turn the screwdriver. Counter clockwise to increase
and clockwise to decrease (1/8 of a turn will move the temperature 5-7 ° in
either direction).
Reinstall the oven knob and recheck the oven temperature.
