V. f - HEAT TINT:
Darkened areas, called “heat tint”, may appear on stain-
less steel exposed to excessive heat, which causes the
protective lm to thicken. It is unsightly but is not a sign
of permanent damage.
To remove heat tint, follow the routine cleaning procedure.
Stubborn heat tint will require heavy-duty cleaning.
V. g - CALIBRATION PROCEDURE:
All units are tested and calibrated to run precisely as
designed prior to shipment. However, if over time there
becomes a need to calibrate or adjust the sensors please
utilize the procedure noted below.
First, set the CAL OFF Set parameter to 0 using the
procedure described under User Adjustable Parameters.
Place a precision thermometer inside the oven’s cavity.
Turn on the oven and adjust the HOLD Temperature to
160 Degrees. When the oven has reached the set tem-
perature wait another 10 minutes for temperatures to
become homogenous inside the oven, read the precision
thermometer and compare it to the oven’s temperature
display. If the oven’s current temperature display is
greater than the precision thermometer reading, the
CAL OFF Set must be set negative (-) the number of de-
grees that the oven display is higher than the precision
thermometer reading. If the oven’s current temperature
display is lower, the CAL OFF Set must be set positive
the number of degrees that the oven display is lower than
the precision thermometer reading.
EXAMPLE
The oven’s current temperature display after reaching 160
and a 10 minute wait is 161. The precision thermometer
reading is 164. The CAL OFF Set parameter should be
set to 3.
EXAMPLE
The oven’s current temperature display after reaching 160
and a 10 minute wait is 160. The precision thermometer
reading is 156. The CAL OFF Set parameter should be
set to -4.
