INSPECTION & ASSEMBLY
UNCRATING AND INSPECTING
Unpack the unit and components from the shipping container. Remove all visible packing
material and those from inside the cooking chamber. If damage is discovered, le a claim
immediately with the carrier that handled the shipment. Do not operate the unit if it was damaged
during shipping.
The following should be included: Miniveyor Multi-Purpose Oven, Stainless Steel Load Up &
Unload Trays, 4 Stainless Steel Legs.
REMOVE ALL HEATING ELEMENT SHIPPING SUPPORTS PRIOR TO PLACING
YOUR UNIT INTO OPERATION.
ASSEMBLY AND INSTALLATION
The unit was shipped with certain assembly required, plug into a standard outlet specied for its
voltage and amp draw. If improper electrical supply is determined, contact a qualied electrician
prior to using the unit. Removal and replacement of the power cord and plug will void the
warranty. For assistance, contact your local authorized service agent for service or required
maintenance.

ASSEMBLY AND INSTALLATION
continued
Install unit in its operating position allow
sufcient space for operating personnel.
Install the Crumb, Load and Unload Trays
as shown, making sure the ends are at
least 6" from any vertical combustible
surfaces.
Have an electrician connect input power
to the unit(s) in accordance with local
electrical codes. A connection terminal
block is inside the left side cavity for
models not provided with a cord and plug
set.
ELECTRICAL CONNECTION
Before making any electrical connection
to this unit, check that the power supply is adequate for the voltage, amperage and requirements
stated on the rating plate.
A wiring diagram is included herewith.
Disconnect the unit from the power source before installing or removing any parts.
Be absolutely sure that the ground connection for the receptacle is properly wired. Do not connect
equipment to power without proper ground connections. Improper grounding may result in personal
injury or fatality.
DO NOT CUT OR REMOVE THIS PLUG OR GROUNDING PRONG FROM THE PLUG.
CONNECT/PLUG UNIT INTO DEDICATED A.C. LINE ONLY SPECIFIED ON THE DATA
PLATE OF THE UNIT.
HEATING ELEMENTS
Inspect all heating elements in the unit for breakage. Every unit is properly tested prior to leaving the
factory, but damage may of occurred during shipping. If a broken tube is found, do not apply power to
the unit. If everything checks out, Turn on Main Power Switch, Turn both heat controls and conveyor
belt speed control to the maximum setting and check all heater tubes and conveyor for proper
operation.
COOLING SYSTEM
After the unit is initially turned on, allow 5 to 8 minutes for the fan cooling system to come on. Once
on, check the air intake area located under the unit and be sure that there is a sufcient ow of air
into the control box. Keep area under the unit clean from obstructions that may result in restricted air
ow to the control box. Restricting the air ow will cause the unit to run hotter then designed, causing
the Hi-Limit to turn unit off. See the Oven Components section on page 7 for control box & Hi-Limit
Reset locations.
FINAL CHECK
If all heaters and conveyor systems are operating properly, switch the master on/off switch to the OFF
position and allow unit to cool, the fan will continue to circulate air, cooling the unit until the internal
temperatures have been decreased.
If a problem is discovered during any of these start-up procedures, immediately switch the master
on/off switch to the OFF position and notify the Star Service Department at [phone].

STACKING OVENS
When stacking two Holman Miniveyor Ovens a stacking spacer with an external air duct MUST be
used to prevent overheating of the control box of the top oven.
1. Place bottom unit in position where the oven will be located.
2. Place stacking spacer on top of the bottom oven with internal air duct facing up and
towards the rear of the oven.
3. Mount external air duct on stacking spacer as shown below.
External air duct must be installed for cooling system of top unit to function properly.
4. Screw set screws (Qty 4) into leg hole on the top oven.
5. Place top oven on stacking spacer. Set screws will set into cut out in top of stacking
spacer to lock unit into position.
NOTE: Air intake of top unit must t over the internal air duct of stacking
spacer to allow airow into the control box of the top oven.

DAILY OPERATION
Baking in these units is a combination of heat and belt speed. Some foods may require more top heat
or visa versa; other foods may require low top and bottom heat and slow belt speeds. Every product
should, therefore, be tested using the separate top & bottom controls and the variable speed control
to arrive at the correct balance of heat and belt speed. When changing heat and or belt speed setting
allow approx. 5 minutes for the oven to stabilize itself at the new settings.
Check the power cord to insure that it is plugged into a proper outlet.
Always allow 10 to 15 minutes of preheat time before loading the unit with product. Failure to
allow sufcient preheat time will result in unsatisfactory cooking until the cooking chamber reaches
operating temperature. Even though the elements can reach there operating temperature very quickly,
a certain amout of time in needed to allow the cooking chamber to reach its operating temperature.
1) Turn the master on/off switch to the ON position.
2) Set both the top and bottom heat controls to 500°F (260°C).
3) Turn conveyor speed control to the fastest setting.
4) Allow 15-20 minutes for initial warm up,
(5 to 8 minutes to reach adjusted temperature, once unit is fully warmed up)
5) Once the unit is pre-heated, adjust the controls to the proper setting for the product
you are preparing.
CERTAIN SURFACES ARE EXTREMELY HOT DURING OPERATION AND CARE
SHOULD BE TAKEN WHILE USING THIS UNIT.
