III. INSTALLATION (cont’d)
All Traulsen products are factory tested for performance
and are free from defects when shipped. The utmost care
has been taken in crating this product to protect against
damage in transit.
You should carefully inspect your unit for damage during
delivery. If damage is detected, you should save all the
crating materials and make note on the carrier’s Bill Of
Lading describing the damage. A freight claim should be
led immediately. If damage is subsequently noted during or immediately after installation, contact our customer
care team to le a freight claim. There is a fteen (15)
day limit to le freight damage with the carrier. Under no
condition may a damaged unit be returned to Traulsen

III. INSTALLATION
III. a - PACKAGING:
Your unit is packed in a cardboard carton which in turn,
is banded to a wooden pallet.
Remove the banding material holding the carton to the
pallet. Remove the cardboard carton and the plastic bag
covering the cabinet and the banding material holding the
cart to the skid. Metal pan slides and shelves are shipped
under the cabinet, in between the casters (careful not to
discard boxes with other packaging material). Remove
items from boxes and install in the interior of cabinet.
Most exterior stainless steel surfaces have a protective
vinyl covering to prevent scratching during manufacturing, shipping and installation. After the unit is installed
in place of application peel, remove and discard the
covering from all surfaces.

III. d - LOCATION:
For efcient cabinet operation, choose a location that will provide
easy loading and unloading without interfering with the nal assembly of food orders.
The nal location must allow adequate clearances for servicing
and air circulation for proper operation.
III. e - ELECTRICAL CONNECTION :
WARNING
Before connecting the oven to the power source,
verify that the voltage and phase of the power source are identical
to the voltage and phase information on the data plate.
WARNING
Electrical and grounding connections must comply with the applicable portions of the National Electrical code
and/or other local electrical codes.
WARNING
Do not store or use gasoline or other ammable
vapors or liquids in the vicinity of this or any other appliance.
The cord and plug come with a proper strain relief to prevent unit
from moving away from electrical connection.
III. b - ELECTRICAL REQUIREMENTS:
Verify that the power source matches the serial tag electrical data, before the connection is made. A dedicated
circuit is required for all models. See page 1 for serial
tag location and data.
III. c - INSTALLATION CODES & STANDARDS:
In the United States, the Traulsen oven system must
be installed in accordance with the following state and
local codes:
Refer to the wiring diagram in this manual for proper connection.
At the circuit breaker, turn off power to the circuit to which the
oven system is to be connected.
Check that the oven power ON/OFF switch is in the OFF position.
Connect the power cord from the oven system to the electrical
power source.
At the circuit breaker, turn on power to the circuit.

• hld Hi 2500 1000 - 250
• CAL OffSEt 00 -300 - +30
rth Lo
This is the RETHERM temperature low limit. It sets the
lowest possible limit for the RETHERM temperature.
Adjustments during normal operation may not be made
lower than this parameter setting.
rth Hi
This is the RETHERM temperature high limit. It sets the
highest possible limit for the RETHERM temperature.
Adjustments during normal operation may not be made
higher than this parameter setting.
NOTE:
Some local codes require the use of a ventilation
hood for equipment operating in excess of 2500 degrees
F. Many will allow operation of Rethermalization ovens
at lower temperatures. Please modify this parameter if
needed to meet local codes.
hld Lo
This is the HOLD temperature low limit. It sets the lowest
possible limit for the HOLD temperature. Adjustments
during normal operation may not be made lower than
this parameter setting.
hld Hi
This is the HOLD temperature high limit. It sets the highest possible limit for the HOLD temperature. Adjustments

IV. c - USER ADJUSTABLE PARAMETERS:
The user’s parameter set menu is entered by turning the oven on
while pushing the START button. The START button must remain
depressed for 4 seconds after power has been applied. The user’s
parameter settings menu is then active. There are 5 adjustable
parameters. Rotate ADJ/SET to change the currently displayed
parameter. Push ADJ/SET to advance to the next parameter. Push
START to accept and save the current parameter settings and

CAL OFFSet
This parameter is a calibration offset and is used in conjunction with a precision thermometer. The cal offset may
be set from -30 to 30 to calibrate the oven temperature
regulation and display.
IV. d - ALARMS:
The oven reports an over temperature condition any time
the oven temperature reaches 400° or higher.
IV. OPERATION (cont’d)
IV. OPERATION (cont’d)
When this condition exists the oven will sound an audible alarm by
emitting a triple beep (three quick short beeps) every 2 seconds
and it will ash the message “Err too Hot” on the display to alert
nearby staff. The audible alarm may be temporarily canceled FOR
3 MINUTES by pushing ADJ/SET. After 3 minutes have expired
the oven will begin beeping again. The error message on the
display cannot be canceled. The proper action when this alarm
is present is to turn the oven off and call for service.
IV. e - TESTING THE OVEN:
Before using the oven for the rst time, verify that the oven operates normally.
Check that the oven is connected to the correct power source.
Turn the oven ON at the power switch.
Use the controls to set the HOLDING TEMPERATURE to 1400F.
Check that the oven circulating fans are running.
Check that the heaters ON indicator is lit.
Check that the oven is warming to the displayed holding temperature.
NOTE:
The cooling fans may not operate when the oven is rst
turned on. The cooling fans operate only when the thermostat
to which they are connected requires it.
Set the TIME to 2 hours, Set the RETHERM TEMP to 2500, push
the START BUTTON, check the interior rear of the oven cavity to
determine that the oven is heating.
Push the ADJ/SET knob to cancel the cycle, set the TIME to 0,
set the HOLD TEMP to 2500F, push the START BUTTON.
Check that the RETHERM TEMP display has been blanked and
the HOLD TEMP display is lighted.
Check the interior rear of the oven to ensure that the oven is
heating. If all the functions perform satisfactory, the oven is
ready for operation.

and press ADJ/SET to accept the retherm temperature.
HOLD is blinking. Rotate ADJ/SET to adjust the hold
temperature and press ADJ/SET to accept the hold temperature. P-x has been updated to the currently displayed
settings and P-x is again blinking. To program another
location rotate ADJ/SET to the desired cycle # then press
