AIR PLENUM FINGER ASSEMBL Y
Outer Perforated

(S t ainless S teel)
Although symmetrical
in design, inner p anel
must have flanges
facing up as shown
Main Panel
(Aluminized S teel)
Inner Perforated
Screen
(S t ainless S teel)
The Outer Perforated p anel is locked into place through a friction fit to the Main p anel. This method
of fastening also captures the Inner p anel, holding it in place. The Outer p anel slides of f the Main
p anel, exposing the perforated Inner p anel. The Inner p anel is symmetrical in design, and may be
placed in either direction, as long as the outer flanges are pointing as shown in the figure
UPW ARD
above.
The Inner and Outer p anels are made of st ainless steel, and therefore may be exposed to strong
cleaners to remove baked-on grease, etc. Overnight soaking in a hot cleaning solution will improve
the cleaning process.
The Main p anel is made of aluminized steel like the main cook chamber , and thus requires the same
level of care to ret ain it s integrity . Follow the same precautions as mentioned above for the main
cook chamber .

THE OVEN. SERIOUS INJUR Y , INCLUDING DEA TH, MA Y OCCUR IF CONT ACT IS MADE WITH
INCOMING POWER.
During normal operation of the oven, lubrication is not required.
T o achieve maximum ef ficiency , keep the oven clean. How you maint ain your oven will determine how long
it last s.
If the oven fails to operate, perform the following inspections BEFORE calling an authorized service agent:
:

1. Check to see if the main circuit breaker is ON at the breaker p anel.
.
2. Check the (2) 5-amp fuses located in the bottom of the Power Control Box
IF FUSES ARE BAD, REPLACE ONL Y WITH IDENTICAL FUSES. DO NOT
SUBSTITUTE HIGHER V ALUE FUSES, AS THIS MA Y NULLIFY NEEDED PROTECTION
FOR THE INTERNAL ELECTRICAL COMPONENTS.
3. Check that the Main Switch is ON. If operating properly , the rocker switch will be lighted
when ON.
4. Check the setting of the temperature control thermost at s (knobs). If operating properly , they
will activate the amber indicator light s a s you turn the knobs back and forth, calling for heat. It
is very unlikely that the light will burn out.

13. CONVEYOR REMOV AL
Extensive Engineering went into designing your oven for ease of cleaning. One SPECIAL
FEA TURE is the ability to remove the conveyor belt assembly straight out the font of the oven.
Follow this procedure, using the diagram provided: (See drawing below)
a) Remove any extension trays present, rot ating them upwards to clear the conveyor frame.
Flanges on the trays hook around the ends of the frame.
b) Remove the two crumb p ans.
c) Remove the upper outer side covers, which have the adjust able baf fles att ached with pins.
The covers are held in place with hand-twist fasteners. T urn these fasteners 90°
counterclockwise to loosen, and 90° clockwise to tighten.
d) It is not necessary to remove the outer lower side covers.
NOTE:
On Dual Air Models VH-, VHV A Series ovens, the outer upper and lower covers
1828E
are symmetrical, and can be mounted on either side of the oven.
e) Open the front hinged door .
f) Carefully supporting both right and lef t sides of the conveyor , lif t the front edge slightly and
pull towards you, watching as the drive shaf t pulls out of the gearmotor coupling.
14. CONVEYOR INST ALLA TION
Inst alling the conveyor belt assembly is done in exact reverse order to it s removal. The MOST IMPOR T ANT
POINT is to properly align the drive shaf t pin with the gearmotor coupling. If the drive shaf t pin must be
wedged into place for inst allation, the coupling location needs to be adjusted. See Section 6a for this
procedure.
DO NOT FORCE THE DRIVE PIN INT O THE COUPLING IF THEY DO NOT ALIGN.

15. CONVEYOR BELT SPEED CALIBRATION
The conveyor belt requires calibration to properly align the speed control knob on the Electric Control Box.
Calibration is done by timing the belt as it passes between two timing marks located on the conveyor frame.
This method will work regardless of belt travel direction. Follow the instructions below.
Idler Shaft
Belt Travel
(Standard)
Timing Marks
on Conveyor Frame
Conveyor Frame
A. Remove the adjustment knob of the conveyor belt speed control (see page 10) using a small,
standard screwdriver to loosen the setscrew.
B. Locate the two timing marks as shown above. For the Dual Air VH-, VHVA1620E series, the marks
are 5 inches apart; for the Dual Air VH-, VHVA1828E the marks are 7 inches apart. IF the timing
marks are NOT present, use ablack markingpen to mark the frame in the same manner.
C. These distances represent exactly ¼ of the distance of the cook chamber: ¼ x 20” cook chamber
(DualAir 1620E) = 5”; ¼ x28” cook chamber (DualAir 1828E)= 7”.
D. With this 1:4 ratio,it is possible to calibrate the belt speed. For example:
1. For a cook time of 1 minute, the time required to pass between timing marks would be: 60
seconds / 4 = 15 seconds. If the belt passes from one mark to the next in 15 seconds, this is
exactly the same as a 1-minute cook time.
2. For a cook time of 6 minutes, the required time to pass between timing marks would be: 6
minutes x 60 seconds / 4. This equals 360 seconds / 4 = 90 seconds between marks. The
belt needs to take 90 seconds (1-1/2 minutes) to move from one mark to the next to equal a
6-minute cook time.
E. Using a black marking pen, mark any belt link near the outer edge. Using a stopwatch, check the
time it takes for this link to move between the timing marks. Repeat this procedure several times
until the distance is traveled in 90 seconds (recommended calibration interval), which equals a 6minute cook time.
F. Now that the belt is moving at this calibrated speed, CAREFULLY re-mount the adjustment knob
onto the belt conveyor speed control shaft, and tighten the setscrew so that the KNOB indicating
mark is pointing at the number “6” on the surrounding label.
G. The conveyor belt is now calibrated for ALL ranges as indicated on the label. The label numbers are
COOK TIME in MINUTES. Simply point the knob indicating line to the desired cook time.

breaker for 1 minute . If "FAULT" light
persists, and all previous tests show
normal, speed control can be tested in the
following manner: swap motor wires from
"good" speed control to "bad" control, and
see if blower motor works. If YES, then
"FAULTY" control is bad and needs
replacing. If NO, then "FAULTY" control is
OK, and motor may need replacing.
6. Test potentiometer by swapping "bad"
pot to "good" speed control. If motor then
works properly, pot is OK, and other speed
control needs testing. (model VHVA-Series

TESTS TO BE PERFORMED ONLY BY
AN AUTHORIZED SERVICE AGENT.
1. Locate the two temperature contols
mounted on the hinged door, near the
cooling fan. Verify that ALL connections
and connectors are properly fastened and
tight. Power should be connected to
terminals labeled 240 & VAC COM.
2. Locate the two wires from each of the
temperature sensors (top left terminals
labeled PROBE). These have braided
insulation. Verify their integrity.
3. If necessary to test, disconnect one
sensor at a time, and use voltmeter to
measure resistance at sensor wires.
Compare to resistance chart in back of this
manual. If sensors show INFINITE
resistance, sensor is bad. Replace.
4. If resist ance reads value within range of
chart, sensor is good, control needs further
investigation. Re-connect sensor wire
leads. (See diagram at back of manual for
proper identification of controls).
NOTE: temperature sensor lead wires
are NOT polarity sensitive, since sensor
is an RTD-type.

17. TEMPERATURE CONTROL CONVERSION CHART
The temperature sensor (probe) that is supplied with this conveyor oven is an RTD type, which yields an
output based on Ohms of resistance. This particular RTD device has a linear resistance curve that
produces a very predictable amount of resistance that can be converted to degrees Fahrenheit. This
particular device produces a resistance increase of 2 Ohms per every 1 degree F. The baseline value is
approx. 1000 ohms at 32 °F (0°C).
