SINCE RESETS FOR THE CIRCULATION BLOWER MOTOR AND
WARNING
THE LIFTER MOTOR / ROTATOR MOTOR ARE AUTOMATIC, ALL
POWER TO THE OVEN MUST BE TURNED OFF BEFORE
SERVICING.
Motor Reset
One of the overload protectors may require resetting if the circulation blower does not start, quits or if the
rack does not lift and rotate with the loading door closed. This is done automatically-nothing has to be
done by the operator. After a few minutes, the oven should reset and normal operation should resume. If
it has not after fifteen minutes, call for service.
If shutter settings are to be adjusted differently than the
NOTICE
recommended factory settings, the best results will be obtained
if you (A) start with the factory settings, (B) close shutters to
lighten a product in a given area- do not open shutters to darken
a product, (C) do not move a shutter more than 1/32" or 1mm
(see step gauge illustration) at any one time, (D) be sure all
settings for left hand shutters match those for right hand
shutters, and (E) do not adjust more than two shutters per side
per time (four shutters total).
Uneven Baking
If side-to-center bake is uneven, check the angles of the wings to determine if they match the factory
settings. (The air wings are long, adjustable, channel-shaped parts that are attached to the fixed vertical
sides of the pressure panel. There are two air wings per oven.) The angles of the air wings must be
checked while the oven is cool.
If side-to-center bake is uneven, check the angles of the shutters to determine if they match the factory
settings. (the angles shutters are short angles located on the pressure panel. There are 12 shutters per
oven.) The angles of the shutters must be checked while oven is cool.
Air wing adjustment screw pairs must be tightened/loosened at
NOTICE
the same time to adjust the angle of the air wing. In other words,
one screw of the pair must be tightened as the other screw is
loosened. Air wings can be adjusted singly or together to modify
a side-to-center bake. Be advised that adjusting air wings affect
the entire rack from top to bottom. For this reason, the angle of
air wings should never be changed more then 1 degree at a time.
Use the "Air Wing Adjustment Diagram" in the Appendix section
of this manual as a guide when making adjustments. When
desired angle is obtained, check all adjustment screws – They
all must be tight!
