The Steam mode provides the operator with the ability
to steam, poach, or blanch. This mode will automatically
steam at the boiling point of water; quick-steam above the
boiling point for faster cooking results; or low temperature
steam, below the boiling point, for more delicate products
such as pâté, mousse, seafood, or custard.
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.
The Convection mode operates with hot circulated air
within a temperature range of 85° to 485°F (29 to 252°C).
For many applications, better results may be
achieved with the Combination mode; therefore, the
operator may want to consider using the Convection
mode on a more limited basis.

CombiClean CLEANING AGENTS
NOTICE: Use authorized Combitherm 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.
CAUTION: Causes eye, skin, and respiratory tract
irritation. keep out of reach of children.
PRECAUTIONS:
- Do not take internally.
- Avoid contact with eyes and skin.
- Use rubber gloves when using this product.
- Wash hands thoroughly after handling.
- Avoid mixing with strong, concentrated acids.
FIRST AID:
Skin: Flush with water. Remove contaminated clothing
and do not re-wear until washed. If irritation persists see
a physician.
Eyes: Flush with water for 15 minutes. See a
physician immediately.
Inhalation: If difculty in breathing occurs, leave area
immediately and do not return until dust is settled. If
irritation persists, see a physician.
Ingestion: Drink large quantities of milk or water. DO
NOT INDUCE VOMITING. See a physician immediately.
PROTECTIVE PACKAGING OF TABLETS WILL
BEGIN TO DISSOLVE ONTO SKIN IF HANDLED
WITH DAMP OR WET HANDS.
CombiClean tablets are to be used only with the factory installed automatic cleaning option.
DANGER
ALWAYS wear rubber gloves when using
CombiClean tablets or spray oven cleaner.
DANGER
ALWAYS wear protective eye wear
when using spray oven cleaner.

PREVENTATIVE MAINTENANCE
MN-36008 (Rev. 8) 01/16 • COMBITHERM CT EXPRESS • B-3
PREVENTATIVE MAINTENANCE
In addition to the routine cleaning and maintenance
procedures, there are several additional steps to be
taken for both sanitation and to keep the oven running
efficiently. Refer to the following inspection checklists for
acomprehensive approach to longevity and equipment
efficiency. These additional safeguards will help prevent
down time and costly repairs.
DO NOT DISPOSE OF GREASE, FAT, WOOD
CHIPS OR SOLID WASTE DOWN THE OVEN
DRAIN.
Fats and solids will eventually coagulate in the drain system,
causing blockage. Consequently, water will back-up into the
condenser and interior oven compartment, resulting in an
oven that is inoperable.
MAKE CERTAIN THE DRAIN SCREEN IS
ALWAYS IN PLACE. REMOVE ANY SOLID WASTE
MATERIAL FROM THE OVEN BOTTOM AND
DRAIN SCREEN BEFORE IT ENTERS THE DRAIN
SYSTEM.
The routine removal of solids from the drain screen will help
prevent blockage.
USE THE AUTHORIZED COMBITHERM OVEN
CLEANER ONLY.
The use of unauthorized cleaning agents may discolor or
harm the interior surfaces of the oven.
TO PROLONG THE LIFE OF THE DOOR GASKET,
CLEAN THIS ITEM DAILY.
The acids and related compounds found in fat, particularly
chicken fat, will weaken the composition of the gasket unless
cleaned on a daily basis. Wipe with a hot, soapy cloth.
TO ADDITIONALLY PROTECT GASKET LIFE,
ALLOW OVEN DOOR TO REMAIN SLIGHTLY
OPEN AT THE END OF THE PRODUCTION DAY.
An open door will relieve the pressure on the door gasket.
ROUTINELY CLEAN DOOR HINGES.
Open oven door to relieve tension. Clean all parts of
the hinge.
ON A MONTHLY BASIS,
DECALCIFY OR DESCALE
THE OVEN.
Using the Scale Free cleaner,
CE-27889, place 7 ounces of the
product in the drain. Run a Heavy-
Duty cleaning cycle. After the
cleaning cycle has been completed,
use the hand shower to spray down
the oven interior. Swing open the
interior fan guard and spray down
the area behind the panel. Direct a
stream of water down the interior
drain cover to thoroughly rinse
the cleaner out of the oven. After the oven interior has been
sprayed down, run a RINSE cleaning cycle.
WARNING
When smoking is completed, remove smoker box
from oven. Dispose of wood chips in a fire proof
waste receptacle to prevent the risk of fire.
DANGER
To prevent SERIOUS PERSONAL
INJURY, DEATH, or PROPERTY
DAMAGE:
DO NOT steam clean, hose down
or flood the interior or exterior
with water or liquid solution of
any kind. DO NOT use water jet
to clean.
Failure to observe this precaution
will void the warranty.

PROTECTING STAINLESS STEEL SURFACES
It is important to guard against corrosion
in the care of stainless steel
surfaces. Harsh, corrosive,
or inappropriate chemicals
can completely destroy the
protective surface layer
of stainless steel. Abrasive
pads, steel wool, or metal implements will abrade
surfaces causing damage to this protective coating
and will eventually result in areas of corrosion.
Even water, particularly hard water that contains
high to moderate concentrations of chloride, will
cause oxidation and pitting that result in rust
and corrosion. In addition, many acidic foods
spilled and left to remain on metal surfaces are
contributing factors that will corrode surfaces.
Proper cleaning agents, materials, and
methods are vital to maintaining the appearance
and life of this appliance. Spilled foods should be
removed and the area wiped as soon as possible
but at the very least, a minimum of once per day.
Always thoroughly rinse surfaces after using a
cleaning agent and wipe standing water as quickly
as possible after rinsing.
CLEANING AGENTS
Use non-abrasive cleaning products designed for
use on stainless steel surfaces. Cleaning agents
must be chloride-free compounds and must not
contain quaternary salts. Never use hydrochloric
acid (muriatic acid) on stainless steel surfaces.
Failure to observe this precaution will void the
warranty. Always use the proper cleaning agent at
the manufacturer's recommended strength.
Contact your local cleaning supplier for
product recommendations.
CLEANING MATERIALS
Cleaning can usually be accomplished with the
proper cleaning agent and a soft, clean cloth.
When more aggressive methods are needed, use a
non-abrasive scouring pad on difficult areas and
make certain to scrub with the visible grain of
surface metal to avoid surface scratches. Never
use wire brushes, metal scouring pads, or scrapers
to remove food residue. Failure to observe this
precaution will void the warranty.
CLEANING AND PREVENTATIVE MAINTENANCE
CAUTION
To protect stainless steel surfaces,
completely avoid the use of
abrasive cleaning compounds,
chloride based cleaners, or
cleaners containing quaternary
salts. NEVER use hydrochloric acid
(muriatic acid) on stainless steel.
NEVER use wire brushes, metal
scouring pads or scrapers.

WARNING
To prevent SERIOUS INJURY,
DEATH, or PROPERTY DAMAGE:
The appliance must be cleaned
thoroughly to avoid deposits of
grease and or food residues inside
the appliance that may catch fi re. If
fat deposits and/or food waste inside
the appliance ignite, shut down the
appliance immediately and keep the
appliance door closed to extinguish
the fi re. If further extinguishing is
required, disconnect the appliance
from the main power and use a fi re
extinguisher (do not use water to
extinguish a grease fi re!). Failure
to clean the appliance properly
invalidates the warranty and relieves
Alto-Shaam of all liability.
