To inspect these white ceramic elements, use a small mirror held under each element to

Important: The Ceramic elements are fragile and will break under
stress. Do not twist, pull, push, or otherwise subject the white ceramic elements to
stress.

5. Wipe down the exterior of the unit using a cloth with warm water. Do not use abrasive pads or
cleaners as they will damage the stainless steel surface and high temperature plastic.
NOTE: DO NOT USE CLEANERS OF ANY KIND ON THE WHITECERAMIC HEATERS.

6.

Remove four feet from box and install into threaded nuts located at the four corners underside of the
left and right housings; Also remove conveyor extension tray(s). Conveyor extensions should be
hung off end of conveyor frame. Model XWAV 1422EZ and XWAV 1829EZ will have two conveyor
extensions for loading and exit ends.

7. Place unit in operating location.

Oven Stacking

The stacking kit willconsist of 4 cornerposts to be inserted
between stacked units.

Warning:

When stacking, unit must have proper
stacking kit installed. This will prevent overheating
and damaging of electrical components.

Warning:

Do not stack more than three units tall or do

not use more than two stacking kits.

Warning:

Standoff on rear panel of unit is important to
allow proper inlet and exhaust fan airflow. Do not
cover inlet or exhaust fan openings as this could
damage electrical components.

1. Ensure bottom unit is mounted on secure

surface, with feet installed.

2. Remove respective corner end caps and

screws. This will allow each of the stacking
spacer retaining fingers to slide into the
extrusions.

3. Remove the feet from the top unit as shown.

4. Secure each stacking spacer to the bottom of

the unit as shown by using the bolts and
washers provided. You should have four total
of each.

5. Once the stacking kit spacers are secure, place

top unit onto bottom unit. The stacking kit
spacers each have tapered guides to allow the
unit to lock into position.

6. Refer to Figure 1. Install rear support bracket

and screws as shown. Each stacking kit
requires that two brackets be mounted on the
backside only. One bracket near the strain
relief and one at the opposite end.

7. Refer to Cleaning Instructions for cleaning of

stacking spacers and cleaning between units.

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.

2. 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)

B. (EZ MODELS)

1.

The direction of the belt conveyor travel is controlled by a hidden rocker switch located
beneath the left side conveyor extension, behind a removable cover attached to the base
housing panel. To change belt direction, remove this cover, flip the rocker switch to the
opposite setting, and replace the cover. This operation can be performed while the belt is
moving.

A. Display

Set point temperature is displayed as a range: 1, 2, 3,..., 14, 15. 1 corresponds to the lowest sensor
temperature and 15 corresponds to the highest sensor temperature.

The factory default setting is 8.
Once the settings are changed and the unit is turned off, these new settings will remain in memory

and appear in the display once the unit is turned on.

B. Preheat Mode

· Unit powers up in this state

· Unit displays Lo and the active bottom and active top LEDs are on whenever the corresponding
zone output is active.

· A normal press of Bottom Zone key selects this zone (its LED lights up) and display shows its current
set point for 5 seconds

· A normal press ofTop Zone key selects this zone (its LED lights up) and display shows its current set
point for 5 seconds

· Up and Down keys are used to change setpoint of current zone. Set point is displayed for 5 seconds
after last Up or Down key press, then normal display resumes. Default set points are definedin Low­level parameters.

· Preheat state ends when top and bottom zones are within the Low Temperature threshold
defined in Low-level programming.

A. Zone Probe Error

· Heater probe is disconnected or defective

· Normal user interface operation applies, but heater output remains inoperative

· Display flashes Alarm LED as well as an Alarm ID:
o AL1 for Zone 1(Bottom probe)
o AL2 for Zone 2 (Top, probeA)
o AL3 for Zone 3 (Top, probe B)

· Alarm shuts down all outputs

· Probe must be replaced or re-connected to allow normal use

B. High Temperature Error

· Heater elementis too hot, most likely due to external SSR that failed short

· Display flashes Alarm LED as well as an Alarm ID:
o AL4 for Zone 1(Bottom probe)
o AL5 for Zone 2 (Top, probeA)
o AL6 for Zone 3 (Top, probe B)

· Alarm shuts down heaterregulation.

· The alarm threshold temperature is Low-level programmable

· Algorithm:
o In normal use, if temperature ever goes above (set point + threshold), High Temperature

Error is immediately triggered.

o If set point is changed (lowered) by the user, the unit will look at the current temperature for 2

minutes and display HI. The peak temperature reached during this time is recorded.

o Thereafter, unit monitors the temperature until it reaches set point. During this cooldown

time, standard HI message is still displayed. User may change set point again, but 2-minute
timer is restarted (and oldPeak value still applies.)

· During the cooldown time, if ever the temperature rises the previously recorded peak

not

above

temperature, High TemperatureError is triggered.

· Once set point is reached, rdy is displayed again.

· HI is displayed only if other zone is rdy or also HI. If other zone is Lo, then LH (low-high) is displayed

instead of HI.
