Chamber Loading and Oven Performance
When loading the oven place items in the oven in such way that air
circulation within the oven is not impaired. Note the air flow from the
top section view (FIG. 4). Heated air flows from back to front
along the side walls, moves horizontally toward the chamber
center and then back toward the recirculating blower.
Leave a space between articles on a shelf.
For best processing performance for a single item, adjust one
shelf so that the article is centered in the oven.
Avoid placing articles on the oven floor. Instead use a
shelf at the lowest adjustable position.
Do not place articles against the inner side walls or the slotted
vents in rear air plenum. (This will obstruct air flow and degrade
uniformity).
Do not overload the unit with large or high-density loads. (This
will show by non-uniform processing and/or long heat-through or
processing times).
Placing an article against the side walls or rear blower return vent
opening will greatly affect unit performance i.e. chamber uniformi-
ty, run-up & recovery, maximum operating temperature, and
energy use efficiency.Here are some guidelines that are critical to
optimum oven performance and better/faster work- load processing.
Calibration for this "analog" type control refers to the pointer being centered on the knob temperature marking
when measured against an external temperature measurement device reading of the same temperature.
Calibration of the temperature knob dial is only recommended if your process requires certification or if setting is off by
more than 20°F, due to contact wear from prolonged use.

DO NOT USE THE CALIBRATION ADJUSTMENT TO OPERATE OVEN AT TEMPERATURES
BEYOND ITS RATED RANGE.
CALIBRATION
1. Turn the knob dial to the desired temperature and allow the
oven to settle at that temperature.
2. Pull the press-fit knob from the thermostat shaft, (be careful
not to change the position of the shaft).
3. Using pliers, hold the outside of the shaft, maintaining it in its
original position.
.
4. Using a small flat screwdriver, turn the trim screw, located
recessed within the shaft center to increase or decrease tempera-
ture
(FIG. 5)
Turn the trim screw no more than 1/8 of a turn in the
direction needed. Allow 15 minutes for the temperature to
settle at the new setting before taking a new reading. Make
subsequent adjustments as needed.
