1. RECEIVING
Read the notice on the outside carton regarding damage in transit. "CONCEALED DAMAGE", damage
discovered after opening the crate(s), MUST be reported immediately to the carrier. The carrier will perform
an inspection of the damage and furnish forms for the consignee's claim against the carrier. Retain ALL
packaging material - including outer carton, until the inspection has been completed.
Proper and secure storage facilities should be arranged for the conveyor oven(s) if necessary to protect it
from outdoor or damp conditions at all times prior to installation.
2. LOCATION AND MINIMUM CLEARANCES
Adequate air space must be provided for the proper venting of the rear exhaust air and provision made for
venting of cooking vapors. The Conveyor Oven must be installed in a well-ventilated area.
NOTE: Attached rear rubber bumpers must not be removed and can contact a rear wall if present.
Conveyor Ovens can be installed with "ZERO" clearances (back and sides) from combustible and noncombustible materials. (Rear rubber bumpers are the “Zero” clearance points on the back of the unit.) S e e
rating plate attached to the control box door panel.
The Conveyor Oven is intended for countertop mounting if mounted on the 4" legs provided. The Oven is
NOT approved for mounting on any floor. Keep the area around your conveyor oven free and clear of all
combustible materials.
3. INSTALLATION
Place the conveyor oven and parts as close to the area of final installation before uncrating. Your conveyor
oven is packed sitting on its bottom. Leave it this way until unpacked. The pallet may be left under the
conveyor oven for convenience in further handling. Unpack carefully to avoid damage to the unit. If
concealed damage is discovered, follow the instructions detailed in Section 1 above.
DO NOT LIFT EXCESSIVE WEIGHT
A.
Legs are shipped unattached. Make sure each leg is attached and tightened before placing the
conveyor oven in place. Each leg is adjustable to accommodate variations in the mounting surface.
B.
Using sufficient help (2 or more people), lift the conveyor oven upward and place on the countertop
surface. Lift the conveyor oven by gripping the bottom of the unit. THE FOLLOWING ITEMS ARE
NOT TO BE USED AS LIFTING "HANDLES": Side-mounted control boxes (2), removable front door
(with handles), the conveyor belt assembly, the rear fan housing assembly.
C.
THE CONVEYOR BELT ASSEMBLY IS MOUNTED BACKWARDS FOR SHIPPING. THE
CONVEYOR BELT ASSEMBLY MUST BE REMOVED AND REVERSED PRIOR TO OPERATION.

mounting. For further information on removal and mounting of interior panels, see Section 10,
cleaning.
4. STACKING
Your conveyor oven(s) can be
stacked up to (3) high. Each unit is
built exactly the same, so it does not
matter in which order they are
stacked. For stacking of (2) units,
remove the legs from the second
(upper) unit prior to mounting on top
of the bottom unit. For stacking of (3)
units, it is preferable to use a
"stacking kit", which allows all
conveyor ovens to be supported by
an external framework, such as a
table, with each conveyor oven
having all legs removed.
"CAUTION: If you use a multiple stack

a)
Focus on the angled Electric Control Box containing the Main Switch (GREEN rocker type, lighted).
The VHVA-Series oven is shown, which contains (5) adjustable knobs for blowers, temperature
controls, and conveyor belt speed.
VH-Series ovens only have (3) adjustable knobs that control
temperature and conveyor belt speed. Two indicator lights are mounted to show when HEAT is
being added to the system.

1)
Flip ON the Main Switch.
The switch should light up when ON ( I ),
and be dark when
OFF(O). Normal warm-up time is 20 -30 minutes for maximum temperature. Lower
temperature settings will take less time.
2)
IF THE MAIN SWITCH IS TURNED OFF DURING INITIAL START-UP, LEAVE UNIT OFF
FOR AT LEAST 15 SECONDS TO ALLOW THE AIR VELOCITY CONTROLS TO RESET.
TOGGLING THE SWITCH RAPIDLY (ON/OFF) WILL STALL THE BLOWER MOTORS
AND ALLOW THE HEATERS TO COME ON EVEN THOUGH NO AIR WILL BE MOVING.
THIS CAN DAMAGE THE UNIT.
3)
Turn
the Air Velocity Speed Controls to MAX (full Clockwise rotation) and listen for the
air velocity speed to increase.
4)
Set the Temperature Controls to MAX (full Clockwise rotation).
The Indicator Lights will
illuminate because there is not sufficient heat in the oven. The lights tell you that the heaters
are ON.
5)
Reduce the blower speed by turning the knob half-way (Counter-clockwise, until indicator
mark on the knob is pointing straight UP).
6)
Turn the temperature control knobs to 350°F. As each chamber (upper and lower) reach this
temperature, the indicator lights will cycle ON and OFF, verifying that the heaters are
operating properly in response to heat demand.
7)
As you become familiar with the oven, you will set the Top and Bottom Temperature Controls
to different settings, according to your cooking requirements.
As the oven temperatures
vary, the Indicator Lights will turn ON and OFF as the heaters respond to the cooking
process.
8)
Gradually turn the conveyor belt control Counter-clockwise and verify that the conveyor belt
moves faster and faster. Repeat this process, turning the knob Clockwise, verifying that the
conveyor belt moves slower.
NOTE: AT SPEED SETTINGS ABOVE “10” (10-minute cook time), IT MAY BE HARD TO TELL THE BELT
IS MOVING. PLACE A PAN ON THE BELT TO OBSERVE THAT IT MOVES INTO THE COOK CHAMBER.

SHUTDOWN
COOL-DOWN CIRCUIT
The conveyor oven is supplied with a special “
once the unit has been shut OFF.
” that helps cool the oven quickly
This feature performs the following functions when the Main Switch is
turned OFF at the end of the day:
a)
The blowers keep running to re-circulate air through the air chambers
b)
The heaters shut OFF.
c)
The conveyor belt stops moving.
d)
Once the oven has cooled down to a factory pre-set temperature, the blowers shut OFF.
oven is now completely OFF.
The
NOTE: This pre-set temperature is not adjustable.
NOTE: TO ACCELERATE THE COOLING OF THE OVEN, OPEN THE FRONT DOOR TO ALLOW
COOLERAIR INTO THE SYSTEM.
NOTE: IF THE MAIN SWITCH IS TURNED BACK ON WHILE THE UNIT IS COOLING DOWN, THE
HEATERS AND CONVEYOR BELT WILL RE-ENGAGE TO BEGIN STANDARD COOKING
OPERATION. THIS IS NORMAL AND WILL NOT DAMAGE THE OVEN. HOWEVER, THE UNIT WILL
NEVER GET HOT ENOUGH TO COOK IF THE FRONT DOOR IS OPEN.
9.

11. OPERATOR MAINTENANCE
WARNING DANGER: DISCONNECT THE POWER SUPPLY BEFORE SERVICING OR CLEANING
THE OVEN. SERIOUS INJURY, INCLUDING DEATH, MAY OCCUR IF CONTACT IS MADE WITH
INCOMING POWER.
During normal operation of the oven, lubrication is not required.
To achieve maximum efficiency, keep the oven clean.
How you maintain your oven will determine how long
it lasts.
If the oven fails to operate, perform the following inspections BEFORE calling an authorized service agent:

IF FUSES ARE BAD, REPLACE ONLY WITH IDENTICAL FUSES. DO NOT
SUBSTITUTE HIGHER VALUE FUSES, AS THIS MAY NULLIFY NEEDED PROTECTION
FOR THE INTERNALELECTRICALCOMPONENTS.
:
Check the (2) 5-amp fuses located in the bottom of the Power Control Box
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 thermostats (knobs).
If operating properly, they
will activate the amber indicator lights as you turn the knobs back and forth, calling for heat.

Extensive
Engineering
went
into
designing
your
oven
for
ease
of
cleaning.
One
SPECIAL
FEATURE 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, rotating them upwards to clear the conveyor frame.
Flanges on the trays hook around the ends of the frame.
b)
Remove the two crumb pans.
c)
Remove the upper outer side covers, which have the adjustable baffles attached with pins.
The
covers
are
held
in
place
with
hand-twist
fasteners.
Turn

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-, VHVA1828E Series ovens, the outer upper and lower covers
are symmetrical, and can be mounted on either side of the oven.
e)
Open the front hinged door.
f)
Carefully supporting both right and left sides of the conveyor, lift the front edge slightly and
pull towards you, watching as the drive shaft pulls out of the gearmotor coupling.
14. CONVEYOR INSTALLATION
Installing the conveyor belt assembly is done in exact reverse order to it’s removal. The MOST IMPORTANT
POINT is to properly align the drive shaft pin with the gearmotor coupling.
If the drive shaft pin must be
wedged into place for installation, the coupling location needs to be adjusted.

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.

5” (1620E), or 7” (1828E)
Remove the adjustment knob of the conveyor belt speed control (see page 10) using a small,
standard screwdriver to loosen the setscrew.
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 a black marking pen to mark the frame in the same manner.
These distances represent exactly ¼ of the distance of the cook chamber: ¼ x 20” cook chamber
(Dual Air 1620E) = 5”; ¼ x 28” cook chamber (Dual Air 1828E) = 7”.
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.
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.
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.
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.
NOTE: The label COOK TIME marks are close approximates, and may vary slightly from actual
timing results using the method described.
Cook/Bake Time is not the same as time of delivery. Time of Delivery is the actual time required
for the first item, leading edge to trailing edge. Cook/Bake Time is leading edge to leading
edge. For example, the Time of Delivery for a 16” pizza with a 6 minute Bake/Cook Time (using the
Dual Air 1828 conveyor) is 9.4 minutes.

THE PROBLEM
Oven not hot
enough
THE CAUSE
Temperature setting too low
Cooking too soon
Temperature control not working properly
THE SOLUTION
Turn temperature control knob to right
(clockwise)
Oven takes 30-40 minutes to get up to
stabilized operating temperature.
Turn temperature knobs back and forth.
Do both lights go ON & OFF? If YES, then
temperature controls are OK. If NO, then
malfunctioning light indicates which control
needs further investigation. Use the
following steps to check.
CAUTION: THE FOLLOWING TESTS
ARE PERFORMED WITH LIVE POWER
WITH CONTROL BOX OPEN. THESE
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 resistance 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.
5. If both sensors are good, swap sensor
leads between controls. Turn temperature
knobs ON & OFF. Whichever light works
properly, the OPPOSITE control is bad.
Replace.

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).
