V. MAINTENANCE (cont’d)
V. f - HEAT TINT:
Darkened areas, called “heat tint”, may appear on stain- less steel exposed to excessive heat, which causes the protective film 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
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
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.
