Caution: External Surface Temperatures
The unit's external surface temperatures will be hot. Use caution when touching these areas to
avoid injury.
Warning: Severe Burns - Ceramic Heaters
The white ceramic heaters operate at high temperatures. Do not touch elements after power
is applied to the elements. Incorporated into the front surface of the element is a red color
changing decal. As the element reaches a predetermined temperature, the decal will change
from red to black. The decal will remain black until the element falls below the transition
temperature where it will then return to its original red color. However, the element even if red
will still be extremely hot. This color changing feature is used ONLY for determining if element is
operating properly.
5. The deflector curtains located at the entrance and exit of the unit are used to contain the heat inside
the unit, as well as keep any forced drafts from entering the unit. These curtains aid in efficient
operation of the heaters and can be adjusted to increase or decrease the entrance and exit height.
These curtains should be adjusted to the minimum height required above the conveyor for the
product you are heating.
Control Operation
This oven has 2 heating zones, 1 on top, and one in the bottom. The top zone (Top Heat) is used to
control all 5 ceramic emitters. The bottom zone (Bottom Heat) is used to control the bottom element.
