INTRODUCTION
ECOSMART®TECHNOLOGY
The Alto-Shaam CT Express Combitherm
combination oven/steamer employs
Ecosmart operating efficiencies in the
design and application of all operating
and programming functions. Ecosmart
operational characteristics include the use of a
water barrier to close the oven compartment to the
outside air. While maintaining a non-pressurized
atmosphere, the primary purpose of the Ecosmart
system is to prevent the steam and heat generated
within the oven compartment from freely escaping
to the outside.
The Ecosmart design displaces the air within the
cooking compartment and achieves a higher level
of steam saturation that offers quick-steaming at
temperatures above 212°F (100°C).
This guide is provided as an operational aid with
step-by-step instructions of the basic functions of
the Combitherm oven, along with the many other
additional features of the control.
SIMPLE CONTROL
The Combitherm Simple control features a simple, push button
control that commands all the oven functions. Whether you cook by
time, or cook using the optional product probe, rest assured you will
be able to bake, roast, steam, poach, grill, broil, proof, braise and oven
fry with con dence.
LED display - Easy to read display indicates temperature settings,
time remaining, and various instructions.

INTRODUCTION
NOTE: In a food service application, the catalytic converter technology does have limitations that are specic to
recommended use (product type and volume of food produced). Application, both menu type and production, are
limited. Overproduction and overcooking may result in exceeding conversion capability of the catalytic system and
proper use should be exercised. Additionally, the catalytic converter system will not capture steam emission (during
normal steam and/or combination cooking modes) from the oven cavity when the oven door is opened.
This product conforms to the ventilation recommendations set forth by NFPA96 using EPA202 test method. The oven
shall be used for the cooking or warming of pizza, bread, bakery products, or similar items only. No raw animal protein
products (skin-on poultry, ground meats, bacon, sausage, steak, etc) shall be cooked in the equipment unless mechanical
ventilation is provided. Precooked foods such as animal, sh, or skinless poultry protein products may be reheated in
the oven. The oven must be operated in a well-ventilated area approved for food preparation. If cooking fatty proteins,
it is recommended that the local HVAC codes and authorities are consulted to ensure compliance with ventilation
requirements. Ventless allowance is subject to and dependent upon local jurisdictional approval and some jurisdictions
may not recognize the NSF/UL certication or application.

MN-29806 (Rev. 3) •CT EXPRESS STEP BY STEP OPERATION MANUAL • 3
NOTE: Automatic steam venting is a standard safety
feature built into all Combitherm oven models.
This feature vents all steam from the oven
compartment immediately before cooking time
expires or set probe temperature is reached.
This function is provided in all programmed
and timed production when operating in any
Steam, Combination, Convection, and Retherm
cooking mode. Automatic steam venting does
not function if the oven door is opened before
time expires or when the oven has been set to
continuous operation.
NOTE: Use authorized combitherm oven cleaner only.
unauthorized cleaning agents may discolor or
harm interior surfaces of the oven. Read and
understand label and material safety data sheet
before using the oven cleaner.

STEAM MODE CHEF OPERATING TIPS
This mode will steam a full or partial load of a single
product, or multiple products without transfer of avors.
When steaming multiple products, however, individual
product cooking times must be taken into consideration.
The non-pressurized atmosphere of the Combitherm
also provides the ability to open the door during the
steam mode in order to monitor products more closely
throughout the steaming process.
STEAM
Perforated, 2-1/2" deep pans (65mm)
are particularly suitable for use in
this program mode. These pans will
provide a shorter cooking time and
will prevent product over-cooking at
the bottom of the pan.
Separate ice-encrusted vegetables
before steaming to ensure
even cooking.
A variety of products can be steamed
at the same time but attention must
be paid to the different cooking times
required for each food product.
HIGH TEMP STEAM
High temperature steaming is
suitable for hearty, root-type
vegetables such as potatoes, turnips,
carrots, and cabbage.
High temperature steaming
provides a cooking time which is
approximately 10-percent shorter
than the regular steam mode
temperature of 212°F (100°C).
Set the steam cooking temperature
between 221°F (105°C) and 230°F
(110°C) for small loads and between
230°F (110°C) and 250°F (121°C) for
full loads.
LOW TEMP STEAM
The low temperature steam mode
will function whenever the oven
compartment temperature is below
212°F (100°C).
It will take longer to steam products
using the low temperature
steam mode.
Steaming sausages in low
temperature steam prevents cracked
or peeling skins.
Use low temperature steam for
delicate foods such as shrimp, sh,
seafood, and crème caramel.
For best results, low temperature
steam all delicate food items at a
temperature of 210°F (99°C)
or below.

The Combination mode will prove to be the most versatile
and widely used mode the Combitherm oven has to offer.
It will produce the best possible results on the widest
variety of products — all within the shortest period of
time. The unique control function of this mode enables
the operator to roast or bake with a combination of steam
and convection heat. In addition to shorter cooking times,
this combination of steam and heat offers less product
shrinkage and more moisture retention than obtained in a
standard convection oven.

COMBINATION MODE CHEF OPERATING TIPS
The Combination mode injects the optimum amount of
steam automatically. There is no need to select moisture
levels. Foods do not dry out. Flavors are retained with no
transfer of avors when mixing product loads.
Due to automatic steam adjustment, the door can be
opened at any time during a cooking operation. Be
certain to observe the safety warning when opening the
oven door.
The Combination mode is particularly efcient when
used for baking, broiling, grilling, stewing, braising,
and roasting.
When using the Combination mode, cooking temperatures
can be reduced 10- to 20-percent below the temperatures
used for conventional cooking methods.
Cooking time will be reduced approximately 40-percent
when cooking at the same temperature used for
convection oven cooking and up to 50- to 60-percent less
time when cooking at the same temperature used for a
conventional oven.
Food browning in the Combitherm begins at a cooking
temperature of approximately 250°F (120°C).
A higher cooking temperature results in heavier browning
but also results in greater product weight loss. To achieve
additional browning use the Moisture Vent Key or set
Gold-n-Brown into the product procedure. Gold-n-Brown
is particularly useful for adding color to high moisture
products such as chicken and other poultry items or
for additional browning of full loads and other
moist products.
The Combination mode provides even browning without
the necessity to turn the pans.
For more even cooking, do not cook in pans deeper than
4" (100mm).

CONVECTION MODE CHEF OPERATING TIPS
The Convection Mode can be used to roast or bake
products needing very short cooking times or for high
moisture products such as mufns, cakes, and cookies, or
for browning the surface of the product.
The Convection mode works best with foods containing
little moisture or for very moist food which require a
dryer nished product.
For baking, preheat the Combitherm at a temperature of
325°F to 375°F (163°C to 191°C). Once preheated, reset the
temperature as required.
A higher cooking temperature results in heavier browning
but also results in greater product weight loss. To achieve
additional browning use the Moisture Vent Key or set the
Browning Feature into the product procedure.

RETHERM MODE CHEF OPERATING TIPS
Since plated meals consist of dissimilar products, there
are several important factors to consider in order to
produce the nest results. Product density (compactness),
thickness, quantity of product on each plate, and quantity
of plates all relate to the length of time necessary to
reheat. Again, experience is the best method to determine
reheating time. Once the time has been determined and
recorded for a specic meal, the results will be consistent
for future reheating times.
HELPFUL HINTS FOR REHEATING
ON THE PLATE
• ALL FOOD COMPONENTS ON THE PLATE SHOULD
BE OF SIMILAR DENSITIES.
• ALL FOOD COMPONENTS ON THE PLATE SHOULD
BE SIMILAR IN THICKNESS.
• ARRANGE ALL FOOD COMPONENTS EVENLY ON
THE PLATE.
• AVOID EXCESSIVE OVERLAPPING OF PRODUCT.
• SAUCES MUST BE HEATED AND ADDED TO
PRODUCT AFTER REHEATING.
• A MIXED VARIETY OF MEALS CAN BE REHEATED
AT THE SAME TIME.
À LA CARTE RETHERMALIZATION
À la carte rethermalization is designed to take a single
plate from a refrigerated temperature to serving
temperature for immediate service. Plates are prepared
in advance, covered, and refrigerated. Preheat the
Combitherm oven. Remove plate from refrigeration and
place in the oven at 275°F (135°C) for an uncovered plate
or 300°F (150°C) for a covered plate. Plates with meat
components will take more time than plates containing
all vegetable components. Follow internal temperature
requirements for reheating and allow for override time.
After reheating, remove the plate from the oven, add any
sauces, garnish, and serve. This process can be repeated
as required.
For the most efcient continuous service, it is suggested
that the Combitherm oven be dedicated to the
rethermalization process during serving hours.
RETHERMALIZING PREFABRICATED AND
VACUUM-PACKED FROZEN FOODS
For bulk product rethermalization, completely defrost
product bags in walk-in cooler. DO NOT REMOVE
PRODUCT FROM THE BAG. Load thawed bags in
preheated oven and rethermalize in the Low Temperature
Steam mode until the required internal temperature is
reached. Place rethermalized bags in a preheated
holding cabinet set at 140° to 165°F (60° to 74°C) until
ready for service.
PLATE COVERS MUST BE USED FOR ON-THE-PLATE REGENERATION.
