ADJUSTMENTS
Oven Door
The “AIR DECK” oven door has adjustability as a design
feature . Although it is factory set, the tension can be adjusted
to suit the operator’s preference . In addition, after a long
period of hard use, the tension can be readjusted as required .
To adjust door tension it is necessary to remove left and
right front corners of unit by the two sheet metal screws .
This exposes the door hinge and spring assembly . The spring
hook passed through a bracket . A 1/” x 20 nut is on the
spring hook forward of the bracket . If it is available, use a
7/16” deep socket and ratchet to turn the nut clockwise to
increase spring tension or counter-clockwise to relieve spring
tension . Make sure to adjust both sides equally .
The oven door is properly adjusted if the door remains fully
open and it the spring tension carries the door to the full
closed position from the half-closed position . Replace the
corner and fasten with screws .
Thermostat Calibration
All electric ovens are equipped with snap action thermostats .
Field calibration is seldom necessary and should not be
resorted to unless experience with cooking results definitely
proves that the control is not maintaining the temperature
to which the dial is set . To check oven temperature when
calibration, use only a reliable mercury thermometer or
preferably an oven pyrometer .
1 . Place the thermocouple of the test instrument or reliable
mercury thermometer in center of the oven .
2 . Turn oven temperature control dial to 00 degrees F
(20 degrees C .) . In order to allow the oven temperature
to stabilize, the oven control must be allowed to cycle
twice before taking a test reading .
3 . Check temperature reading when control just cycles
“OFF”, record that temperature, also record the
temperature when the oven cycles “ON”, as indicated
by the cycling indicator light on the front control panel .
Average the two readings, if the average temperature is
not within ± 20 degrees of the dial setting, recalibrate as
follows:
. Carefully remove the thermostat dial, not disturbing dial
setting .
5 . Hold dial shaft (“A”) steady and with a screw driver, turn
calibration screw (“B”), located inside the dial shaft,
clockwise to decrease and counter-clockwise to increase
the temperature .
EX: 1/ turn = 25 degrees .
6 . Replace thermostat dial and repeat steps 1 through 3 to
verify adjustment has been made .
