THEORY OF OPERATION, SPECIFICATIONS AND INSTALLATION
1
HEORY OF OPERATION
T
The TurboChef®High h Batch speed cook oven
uses high heat transfer rates developed by force air
impingement to rapidly cook food. The High h
batch utilizes top and bottom Jetplates that have
been optimized for specific food items. The plates
can be easily removed and replaced to facilitate
either higher or lower heat transfer rates. As a result,
the operator can cook foods that require maximum
browning/caramelizing (high heat transfer), or more
delicate foods that require low heat transfer to
ensure quality is not compromised.
The technology is similar to but about twice as fast
as the fastest impingement conveyor oven. The High
h Batch utilizes a variable speed blower, oscillating
rack, and Catalytic Converter to provide maximum
speed, minimal energy input, ventless operation and
the highest food quality.

through service or some other action).
Reference Figure 23 (below) to determine when
(i.e., which oven state) a fault can occur.
F1: BLOWER (Blower Running Status Bad)
This fault will display when the Blower Motor
Controller indicates no running status. The oven
responds to this fault by terminating a Cook Cycle
and/or reverting to the Off State. The oven will
automatically attempt to restart every 2 seconds
until the fault is cleared.
To clear this fault:
1. Turn the oven on. The Control System may be
able to successfully restart the Blower Motor.
2. Test the Blower Motor from the Test Mode
Menu (for instructions, see page 24).
Troubleshooting this fault:
To troubleshoot an F1 Fault, see the diagram
on page 18.
F2: LOW TMP (Cook Temperature Low)
This fault will display if the Cook Chamber
temperature is more than 84°F (47ºC) below the
set temperature after 5 seconds into a Cook Cycle.
To clear this fault:
Try cooking again. If the Cook Chamber
temperature is within 84°F (47ºC) of the set
temperature, the fault will clear.

Cooling Fans (Figure 40)
Located on the back of the oven, the Cooling Fans
ventilate air into the Electrical Compartment (via the
inlet fan), then back out (via the exhaust fan).
To replace a defective fan:
1. Ensure “Cool Down” process is completed (“Cool
Down” message will disappear upon completion)
and unplug the oven.
2.
Remove side panel nearest to defective fan.
3. If removing exhaust fan, remove covering.
4. Remove finger guard.
NOTE: The screws that hold finger guards in place
also hold fans in place.
5. Disconnect Wiring Harness from fan.
6. Install new fan (P/N 100516) and reconnect

THE IMPINGEMENT CIRCUIT
Swing Arm Assembly (Figure 58)
The Swing Arm Assembly is actuated by the Rack
Oscillator Motor. The attached oven rack oscillates
when the Swing Arm Assembly is in motion.
If the rack is not oscillating properly,
1. Ensure “Cool Down” process is completed. (“Cool
Down” message will disappear upon completion.)
Ensure recipe settings have the rack set at “ON.”
2.
(See pages 12-14 for modifying recipes.)
3. If recipe settings are correct, ensure the Rack
Oscillator Motor is working properly (page 41).
4. If problem persists, use the figure below to troubleshoot the Swing Arm Assembly.
5. Unplug the oven.
6. Remove all components from the left and right
sides of the oven (including insulation) to access
the Swing Arm Assemblies.
7. Remove the Swing Arm Covers.
Correct problem and reinstall all components.
8.
NOTE: Some oven components have been removed for clarity.

Catalytic Converter (Figure 59)
The Catalytic Converter – a VOC-type catalyst –
cleans the recirculating airflow. The catalyst substantially lowers the combustion temperature of
grease entrained in the air path to approximately
the same temperature of the airflow, thus breaking
down grease into CO
and H2O as it passes through
2
the Catalytic Converter. The catalyst operates most
efficiently at temperatures above 475ºF (246°C).

Oven Cleaner (P/N 103180).
CAUTION: DO NOT use a substitute

9. If necessary, replace the Catalytic Converter
with P/N HHB-8108.
Filters (Figure 59)
The two Filters help prolong the life of the
Catalytic Converter by trapping excess grease.
They are attached to the Air Diverter Plate via the
Filter Clips. When deep cleaning the oven (see
page 59), the operator/technician should check to
see if the Filters need to be replaced.
To remove a Filter:
1. Ensure “Cool Down” process is completed. (“Cool
Down” message will disappear upon completion.)
2. Remove Oven Rack.
