Operation - APW Wyott XWAV1417 Installation And Operating Instructions Manual

1. The controls that operate the unit, heaters and conveyor are located on the front leftside of the unit.
2. The On/Off switch is used to turn the unit on or off. Once the unit is turned on the conveyor will
automatically run. Warning: Ensure no hands, tools or parts are located on the conveyor as injury
will result when unit is turned on.
3. The control display (oval keypad) is used to control top and bottom heat only. The control settings
allow for separate upper and lower zone control. The settings for upper and lower zones are 1
through 15; 1 being coolest and 15 being hottest setting. (See control operation below)
4. Note: Before moving the On/Off switch to the "On" position, please read the following statements:
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 3 heating zones, 2 on top, and a bottom one. The 2 top zones share the same
parameters (set point, probe offsets, etc.) The bottom zone is completely independent of the top
one.
