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.

automatically. There is no need to select moisture levels. Foods do not
dry out. Flavors are retained with no transfer of flavors when mixing
product loads.
Due to the automatic steam adjustment, the
door can be opened at any time during a
cooking operation. Be certain to observe the
safety war ning when opening the oven door.
The Combination mode is particularly efficient
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 Combither m begins
at a cooking temperature of approximately
248°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 tur n the pans.
For more even cooking, do not cook in pans
deeper than 4-inches (100mm).

The Convection mode works best with foods
containing little moisture or for very moist food
which require a dryer finished product.
For baking, preheat the Combither m at a
temperature of 36°F to 54°F (20°C to 30°C) above
the baking temperature required. 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.
To prevent the sur face of food from excessive
drying, the fan will not engage if the inter nal

RETHERM MODE CHEF OPERATING TIPS
Since plated meals consist of dissimilar products, there are several important factors
to consider in order to produce the finest 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
specific 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
required. Follow internal temperature requirements
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 reheating and allow for override time. Remove
For the most efficient continuous service, it is
suggested that the Combitherm oven be dedicated to
the rethermalization process during serving hours.
• BANQUET RETHERMALIZATION
Banquet rethermalization is designed for high
volume, full or partial load (multiple plate) reheating.
For maximum efficiency, it is essential that volume
rethermalization be used in conjunction with the
utilization of holding cabinets to keep rethermalized
food at proper temperatures.
Plates are assembled in advance, covered, and
refrigerated or loaded on the roll-in cart and
refrigerated. Preheat the Combitherm oven at
275°F (135°C) for uncovered plates or 300°F (150°C)
for covered plates. Remove plates or the roll-in cart
from refrigeration, load in the oven and set timer as
the plates or roll-in cart from the Combitherm and
roll into the companion holding cabinet. Relocate
the holding cabinet to the banquet service area.
• 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.
For large volume on-the-plate regeneration,
defrost bags in walk-in cooler. Open bags and plate
per menu requirements in a ( MAXIMUM ) 55°F (13°C)
refrigerated room. Cover plates, place on Alto-Shaam
roll-in cart (trolley), and roll into Combitherm oven
preheated at 275°F (135°C).
Regenerate in the Convection mode for 3 to 5
minutes. Switch to the Retherm mode for an
additional 3 minutes or more if required. Transfer
full trolley to a preheated holding cabinet set at
160°F (71°C) until ready for service. In the case of
meat cooked to rare, set the cabinet at 140°F (60°C).
PLATE COVERS MUST BE USED FOR ON-THE-PLATE REGENERATION.

In addition to the routine cleaning and maintenance procedures, there are several additional steps to be
taken for both sanitation purposes and to keep the oven running at top operating efficiency. These
additional safeguards will help prevent inconvenient down time and costly repairs.

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 DRAIN SCREEN BEFORE IT ENTERS THE DRAIN SYSTEM.
The routine removal of solids from the drain screen will help prevent blockage.

CLEANING AGENTS
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 a day. Always thoroughly rinse
surfaces after using a cleaning agent and wipe
standing water as quickly as possible after rinsing.
USE AUTHORIZED COMBITHERM
LIQUID OVEN CLEANER ONLY
Cleaning agents must be chloride-free compounds
and must not contain quaternary salts. Never use
hydrochloric acid (muriatic acid) on stainless steel
surfaces. 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.
C L E A N I N G M AT E R I A L S
The cleaning function can
usually be accomplished with
the proper cleaning agent
and a soft, clean cloth. When
more aggressive methods
must be employed, 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.
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.

Flushing the electric Combitherm steam generator on a daily basis helps to prolong the life of the steam
generator heating elements and helps prevent the necessity of service requirements. The control provides
this feature as an automatic function when the oven ON/OFF power key is pressed to the ON position at the
start of each working day.
PRESS THE ON/OFF POWER KEY TO THE ON POSITION.
DISPLAY MESSAGE INDICATES:
Flush steam generator?
YES
PRESS THE START KEY OR
CHEF FUNCTION KEY to begin the steam generator flush.
The steam generator is automatically drained, flushed, and refilled with water within 5 minutes or less.
Following this time period, the Combitherm is ready for operation.
NO
TO CANCEL THE STEAM GENERATOR FLUSH, ROTATE THE ADJUSTMENT KNOB ONE TURN TO
THE RIGHT UNTIL THE DISPLAY INDICATES “NO”.
PRESS THE START/STOP KEY OR
CHEF FUNCTION KEY to confirm cancellation.
If steam generator flush cancellation is not initiated within 10 seconds of the appearance of the
display message, the flushing function will automatically start. Following cancellation, the
Combitherm is ready for operation. The flushing process must be initiated manually at a later
time during the working day if not conducted at startup.

1. Press the Power Switch to the OFF position. Rotate the Steam Generator Drain Cap located at the back
of the oven until water begins to flow from the four holes in the cap. In approximately 20 to 60
seconds, a sufficient quantity of water will have drained from the steam generator so that the drain cap
can be completely removed.
2. As the water continues to flow from the generator, it will have a milky or cloudy appearance, which
indicates deposits in the generator are beginning to flush through the system. Let the water continue to
drain until the flow begins to subside.
3. When the flow begins to subside, remove the hand-held hose from the side of the oven and direct a
stream of fresh water directly into the steam generator drain opening located directly behind the Steam
Generator Drain Cap. Repeat this procedure several times until the water begins to run clear.
4. Press the oven Power Switch to the ON position. When the audible signal is heard, press the Steam
Mode Key. A new supply of fresh, cold water will begin to flow through the steam generator. Repeat
this procedure several times until the water runs completely clear.
5. Once the water is completely clear, replace the Steam Generator Drain Cap over the steam generator
drain by turning it clockwise, by hand, until there is a slight resistance.

ScaleFree™ Descaling Compound is an acid-based descaler
combined with a proprietary chelating agent that is effective in
dissolving and removing carbonate, lime-scale and iron scale build-up caused by hard water.
ScaleFree efficiently and effectively removes lime-scale build-up from combi ovens.
ScaleFree™ is a non-hazardous, Biodegradable Citrus Based Powder that when mixed with
water becomes a powerful lime-scale remover.
It is VERY important to decalcify the oven, particularly in areas with extremely hard water.
