SELECTOR SWITCH CALIBRATION
1. Place a pyrometer in the center of the oven.
2. Turn the mode selector switch to cook.
3. Set 8 position selector switch to one of the
eight positions.
NOTE: The 8 individual positions are each set
for a temperature of the customer's
choosing. For example, if position 1 is
set for 350_F (177_C) the red indicator
light should go out when it gets to withĆ
in 10 degrees of setpoint.
4. If the light goes out within 10 degrees, no adĆ
justment is required. If the light does not go out
within 10 degrees of setpoint calibrate the
switch as follows:
A.) Locate the potentiometer on the 8 position
selector switch labeled R1.
NOTE: There are 8 trim pots on this device.
They are labeled R1, R2, R3, etc.
B.) Turn the brass screw on top of the potenĆ
tiometer clockwise to increase the temperaĆ
ture. Turn the brass screw on top of the poĆ
tentiometer counterĆclockwise to decrease
the temperature.
5. Repeat steps 3-4 for all 8 positions.
NOTE: It is possible for all 8 positions to be out
of calibration but highly unlikely.
