3) Turn the Air Velocity Speed Controls to MAX (full Clockwise rotation) and listen for the
airvelocity speedto 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
markon theknob is pointingstraight UP).

6) Turnthe temperature control knobs to 350°F. Aseach chamber (upper andlower) reachthis
temperature, the indicator lights will cycle ON and OFF, verifying that the heaters are
operatingproperly in responseto heatdemand.

7) As you become familiar with the oven, you will set the Topand BottomTemperature 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.

) Gradually turn the conveyor belt control Counter-clockwise and verify that the conveyor belt

8. SHUTDOWN

The conveyor oven is supplied with a special   that helps cool the oven quickly
once the unit has been shut OFF. This feature performs the following functions when the Main Switch is
turnedOFF atthe end of the day:

a) Theblowers keeprunning to re-circulateair through theair chambers
b) Theheaters shutOFF.
c) The conveyorbelt stopsmoving.
d) Once the oven has cooled down to a factory pre-set temperature,the blowersshut OFF. The

ovenis nowcompletely OFF.

NOTE: TO ACCELERATE THE COOLING OF THE OVEN, OPEN THE FRONT DOOR TO ALLOW
COOLERAIR INTOTHE 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
NEVERGET HOT ENOUGHTO COOK IFTHE FRONTDOOR IS OPEN.

CAUTION: DO NOT USE OVEN CLEANERS, CAUSTIC SOLUTIONS OR MECHANICAL MEANS
BECAUSETHESE WILLDAMAGE THE ALUMINIZEDSURFACES

. Use only thedetergent solutions
and cleaners that meet national and/or local codes. Clean the walls of the cook chamber with a mild
soapand watersolution.

To clean the interior of the conveyor oven, it is necessary to remove the front door, the (4) outer sides
panels,the conveyor beltassembly, andthe (4) air plenum fingers.(See page 9.)

ConveyorBeltAssembly

1. CONVEYOR BELT STILL MOUNTED IN OVEN:

NOTE: USE CARE IF CLEANING THE CONVEYOR BELT WHILE IT IS STILL MOUNTED IN
THE OVEN. EXCESSIVE FORCE MAY PRODUCE AN OVERLOAD CONDITION THAT
COULD DAMAGE THE GEARMOTOR AND CAUSE THE OVEN TO BE RENDERED UN-
USABLE.

Using a plastic abrasive pad, wipe the conveyor belt in a back-and-forth motion to remove
baked-on product. Wipe clean with a hot, damp cloth.

2. CONVEYOR BELT REMOVED FROM OVEN:

Using a plastic abrasive pad, wipe the conveyor belt in a back-and-forth motion to remove
baked-on product. Wipe clean with a hot, damp cloth.

NOTE: IT IS NOT NECESSARY TO REMOVE THE BELT FROM THE FRAME ASSEMBLY FOR
CLEANING.

3. Check the belt links for any sign of damage. If any links are bent, use a needle-nose pliers to
repairprior to re-installationinto the unit.

Plenum Fingers

The conveyor oven contains (4) plenum fingers that direct air onto the product surface while
cooking. This 3-piece assemblycomes apart forcleaning, as shownbelow:

Outer Perforated

Panel

(Stainless Steel)

Although symmetrical
in design, inner panel

must have flanges

facing up as shown

Main Panel

(Aluminized Steel)

Inner Perforated

Screen

(Stainless Steel)

The Outer Perforated panel is locked into place through a friction fit to the Main panel. This method
of fastening also captures the Inner panel, holding it in place. The Outer panel slides off the Main
panel, exposing the perforated Inner panel. The Inner panel is symmetrical in design, and may be
placed in either direction, as long as the outer flanges are pointing as shown in the figure

UPWARD

above.

The Inner and Outer panels are made of stainless steel, and therefore may be exposed to strong
cleaners to remove baked-on grease, etc. Overnight soaking in a hot cleaning solution will improve
thecleaning process.

The Main panel is made of aluminized steel like the main cook chamber, and thus requires the same
level of care to retain its integrity. Follow the same precautions as mentioned above for the main
cookchamber.

THE OVEN. SERIOUS INJURY, INCLUDING DEATH, MAY OCCUR IF CONTACT IS MADE WITH
INCOMINGPOWER.

Duringnormal operation of the oven,lubrication is notrequired.

To achieve maximum efficiency,keep the oven clean. How you maintainyour oven will determine how long
it lasts.

If the ovenfails to operate, perform thefollowing inspections BEFOREcallingan authorizedservice agent:

:

13

1. Check to see ifthe maincircuit breaker isON atthe breaker panel.

.

2. Check the (2) 5-amp fuses located in the bottom of the Power Control Box

CAUTION
IF FUSES ARE BAD, REPLACE ONLY WITH IDENTICAL FUSES. DO NOT
SUBSTITUTE HIGHER VALUE FUSES, AS THIS MAY NULLIFY NEEDED PROTECTION
FORTHE INTERNALELECTRICAL COMPONENTS.

3. Check that the Main Switch is ON. If operating properly, the rocker switch will be lighted
whenON.

4. Check the setting of the temperature control thermostats (knobs). If operating properly,they
will activate theamber indicatorlightsas youturn theknobs backand forth, calling for heat. It
is very unlikelythat the lightwill burnout.

5. If there is noair blowing,check the following:

i. RESET

DUALAIR MODELVHVA-SERIES

: theunit by turningthe MainSwitch OFF
for at east15 seconds and then turning it back ON. This resets the blower speed
controls. If this is not successful, turn off the wall circuit breaker for one minute and
thenturn iton again.

ii.

DUAL AIR MODEL VH-SERIES WARNING

: Observing the at the beginning of this
section, open the Power Control Box and locate the overload relay (above
gearmotor). . TrytheMain Switchagain.

1. NOTE:

PUSHIN THERESET BUTTON

The Overload Relay is both a current limiting and a thermal

device

, meaning that if one or both of the blower motors get jammed, the
overload relay shuts the motor(s) OFF if there is excessive current going to
the motor(s), or if excessive heat builds up in the overload relay due to an
overload condition. Because it takes time for the relay to cool down, do not
assume that there is another problem IF pushing the RESET button doesn't
accomplish the task Both settings,

notoverheated

, must becorrect for properoperation.

RESET button pushed IN & overload

:

If the conveyor belt does not move, check to see that the coupling setscrew is tight on the

gearmotoroutput shaft.

If the oven still does not operate, turn OFF the Main Switch and disconnect the power supply to the
unit(if possible). Contactthe factory, factory representative,or an authorized serviceagency.

13. CONVEYOR REMOVAL

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.
Followthis procedure,usingthe diagramprovided: (See drawingbelow)

a) Remove any extension trays present, rotating them upwards to clear the conveyor frame.

Flangeson thetrays hook aroundthe ends of the frame.
b) Remove thetwo 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 these fasteners 90°

counterclockwiseto loosen, and90° clockwiseto tighten.
d) It isnot necessaryto remove theouter lower sidecovers.

NOTE:

On Dual Air Models VH-, VHVA Series ovens, the outer upper and lower covers

1828E

aresymmetrical, and can be mountedon either sideof theoven.

e) Open thefront hinged door.
f) Carefully supporting both right and left sides of the conveyor, lift the front edge slightly and

pulltowards you,watching as thedrive shaft pullsout ofthe gearmotor coupling.

14. CONVEYOR INSTALLATION

Installingthe conveyorbelt assemblyis 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. See Section 6a for this
procedure.

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.

CAUTION: THE FOLLOWING TESTS 1­4 ARE PERFORMED WITH LIVE POWER
WITH CONTROL BOX OPEN, OR REAR
MOTOR COVER REMOVED. THESE
TESTS TO BE PERFORMED ONLY BY
AN AUTHORIZED SERVICE AGENT.

1. Speed control wire connections are
labeled U, V, and W. Insure connectors
are tight.

2. Insure these (3) wires are tight on
terminal block located in blower motor
compartment.

3. Tighten wires from pot to speed control
at the header terminal on speed control
board.

4. One pot wire contains a 15K ohm
resistor at the pot body. Verify this solder
connection is good.

Blower speed control(s) failed

Blower motor(s) failed

5. Blower(s) can stop if speed controls
have not been reset (model VHVA-Series
only). If yellow "FAULT" light on speed
control circuit board is ON, first turn OFF
main Switch for 15 seconds to rest

control(s). If yellow "FAULT" light remains
ON, disconnect main power cord or circuit
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
only).

7. If all previous tests are normal, then
blower motor has failed. Replace.

THE PROBLEM THE CAUSE THE SOLUTION

Oven not hot

enough

Temperature setting too low

Cooking too soon

Temperature control not working properly

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
Replace.

OPPOSITE

control is bad.

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).
