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, fi 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: Proveyor Multi-Purpose Oven, Stainless Steel Load Up &

Unload Trays, 4 Stainless Steel Legs.

CAUTION

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 specifi ed

for its voltage and amp draw. If improper electrical supply is determined, contact a qualifi 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.

Attach the 4 legs by screwing them into the weld nuts located on the bottom of the unit.

When complete, use two people to carefully turn the unit upright. Level unit by adjusting the

Install unit in its operating position allow

suffi cient space for operating personnel.
Install the Load, Unload and Crumb 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.

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
suffi cient fl ow of air into the control box. Keep area under the unit clean from obstructions
that may result in restricted air fl ow to the control box. Restricting the air fl 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
1-800-807-9054.

the holes on the cart. Insert 3/8" bolts through cart and into leg holes to secure bottom unit
to cart as shown below.

2. Place stacking spacer on top of 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 cap screws (Qty 4) into leg hold on the top oven.

5. Place top oven on stacking spacer. Cap screws will set into cut out in top of stacking
spacer to lock unit into position.

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 suffi cient preheat time will result in unsatisfactory cooking until the unit reaches
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-Phase Control Units, set front heat controls to 500°F (260°C)

3) Turn conveyor speed control to the fastest setting.

4) Allow 10 to 15 minutes for initial warm up,
(5 to 8 minutes to reach adjusted temperature, once unit is fully warmed up)
