ELECTRIC COMBI, CONVECTION & STEAM OVENS
SAVE THESE INSTRUCTIONS
GENERAL
The Electric Combi, Convection & Steam Ovens are single compartment ovens that provide convection
heating and/or steaming in the cooking chamber. Humidification can be provided by the internal steam
generator or by water injection (water vaporizes on contact with the hot oven interior).
The Hobart Combi Electric ovens are sized 6, 10, or 20 levels high. The 6 level ovens are Half depth
only. The 10 and 20 level ovens are either Full or Half depth. All models include a programmable
control. The bold numbers and letters explain the model-number conventions.
The 6 or 10 high ovens can be installed on a suitable countertop using the legs (standard) or on an
accessory Stand. The accessory Stand may be equipped with an accessory Pan Slide which provides
rack or pan storage underneath the oven. On 6 or 10 level ovens, the accessory Landing Table can
load or unload all Racks in one motion when the oven is mounted on the accessory stand or on a
countertop at the proper elevation. Additional Pan Racks and Racks are also available accessories.
The 20 level ovens can be installed with legs or with accessory casters. Accessory 20 Level Half and
20 Level Full Trolleys allow loading or unloading all racks in one motion. An available Hose Spray
accessory can be installed near the oven to facilitate easy cleaning.
INSTALLATION
UNPACKING
Immediately after unpacking the oven, check for possible shipping damage. If the oven is found to be
damaged, save the packaging material and contact the carrier within 15 days of delivery.
Prior to installation, verify that the electrical service agrees with the specifications on the oven data
plate.
LOCATION
Allow space for operating the oven. Do not obstruct the ventilation ports above the oven. To provide
ventilation access, allow 4" clearance on the right side of the oven and 6" clearance at the rear. A
suitable amount of space should be provided for machine operation, cleaning, and service.
STACKING KITS
Stacking kits are available to allow ovens to stack, one on top of the other (available for 6 and 10 level
ovens only). The bottom oven must be larger or the same size as the upper oven. Assembly
Instructions are included with the kit.

LEGS OR CASTERS
WARNING: THE OVEN MUST BE BLOCKED AND STABLE BEFORE INSTALLING LEGS OR
CASTERS.
Raise up and block the oven a minimum of 10" from the floor. Threaded holes are provided at the four
corners underneath the oven; screw the threaded stud of the four legs or optional casters into the
threaded holes. Four flanged legs allow anchoring to the floor (anchoring hardware not provided).
Casters with brake should be installed at front, casters without brake, at rear.

* Leg height will vary with application.
Use legs or casters on an oven if setting on floor. To provide common mating heights with trolleys, the
20 level half depth ovens use 71/4" legs or casters while the 20 level full depth ovens use 85/8" legs or
casters. Use legs only on an oven setting on a counter. Use legs or casters on stand if oven will sit
on stand. Use legs or casters on bottom oven with stacking kit.
Casters may be used on an oven setting on the floor (not on an oven setting on a countertop). Casters
may be used on an accessory stand or on the bottom oven with an accessory stacking kit. Caster
equipped units should be installed with flexible plumbing and electrical connections to allow the unit(s)
to be pulled out for cleaning or servicing. When moving the oven, the operator should not exceed the
limitations of any flexible connections.
LEVELING
Caster equipped ovens must be placed on a level floor.
For ovens with legs, use a spirit level or pan of water in the bottom of the oven to make sure the oven
is level, both front-to-back and side-to-side. Adjust the leveling feet on the bottom of the legs by turning
the feet in or out to level the oven. After the drain is connected, check for level by pouring water onto
the floor of the compartment. All water should drain through the drain opening.
CONDENSATE DRIP PAN
Remove screws under front of oven base and assemble condensate
drip pan to bottom of oven (Fig. 2) using the thumb screws supplied
loose with the oven. Condensate drip pan is incorporated with front
cover of Stacking Kit accessory for the upper oven only. The lower
oven of a stacked pair uses the standard condensate drip pan. The
Oven
20 level oven has a three-segment condensate gutter.

WATER REQUIREMENTS
Proper water quality can improve the taste of the food prepared in the oven, reduce liming in the steam
generator, and extend equipment life. Local water conditions vary from one location to another. The
recommended proper water treatment for effective and efficient use of this equipment will also vary
depending on the local water conditions. Ask your municipal water supplier for details about your local
water supply prior to installation.
Recommended water hardness is 2.0 to 4.0 grains of hardness per gallon with pH from 7.0 to 8.0.
Chlorides must not exceed 30 parts per million. Water hardness above 4.0 grains per gallon should
be treated by a water conditioner (water softener or in-line water treatment). Water hardness below
2.0 grains per gallon may also require a water treatment system to reduce potential corrosion. Water
treatment has been shown to reduce costs associated with machine cleaning, reduce deliming of the
steam generator, and reduce corrosion of metallic surfaces in the steam generator.
Water supplies vary from one location to another. A local water treatment specialist should be
consulted before installing any steam generating equipment.
The Kleensteam® system by Everpure is an available Hobart accessory. The Kleensteam system is
a passive chemical feeder that modifies the water supply by addition of a non-toxic chemical which
increases the acidity of water, reducing the alkalinity. This generally allows the steam generator to
run cleaner and require less frequent deliming. Kleensteam reduces the chemical taste and odor of
chlorine and filters out small particulates. The cartridge needs to be replaced every six months.
Sediment, silica, excess chlorides, or other dissolved solids may lead to a recommendation for
alternate form(s) of water treatment. Consult with a water treatment specialist and your Hobart Sales
office for specific recommendations.
PLUMBING CONNECTIONS
WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY
AND PLUMBING CODES.
WATER SUPPLY CONNECTIONS (Fig. 2)
Connect treated potable water (hot or cold) to the inlet labeled for treated water to supply the steam
generator tank and humidifier. Untreated water contains scale producing minerals which, if supplied
to the steam generator, can precipitate onto the surfaces in the steam generator tank. Due to the
temperatures in the tank, the minerals can bake onto the surfaces and components. This can result
in early component failure and reduced product life. Sensors in the steam generator tank use ions in
the water to detect the water level. Do not use distilled (fully demineralized or de-ionized) water as this
could provide a false reading to the sensors. Strainers and filters will NOT remove minerals from the
water.
Connect untreated potable water (must be cold) to the inlet labeled for untreated water to supply the
condenser which cools the drain water.
Water Supply Inlets . . .
at Bottom Rear Corner of Oven
. . . Model HCE6H Shown.
Both external-threaded nylon inlets (3/4" NSHT - National Straight Hose
Thread) are located at the rear of the oven. The nylon threads should be
treated carefully so the connections do not leak. A manual shutoff valve
should be provided, convenient to the oven, for each water supply line; both
of these valves should be open when the oven is in operation. Water
pressure for both incoming water lines should be between 20 and 80 psig.
Refer also to CLEAN CYCLE DELIMING PROCEDURE, page 29.
Fig. 2

DRAIN CONNECTION
CAUTION: In order to avoid any back pressure in the oven, do not connect solidly to any drain.
Extend the drain line from the 11/2" NPT drain pipe extending from the bottom of the oven at the rear
to an open gap-type drain. Drain piping must have suitable pitch, have appropriate support along its
length, and have no connection to other piping. The material used in the drain line should be heat
resistant to at least 212°F.
ELECTRICAL CONNECTION
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH APPLICABLE
PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL ELECTRICAL CODES.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE
DISCONNECT SWITCH INDICATING THAT YOU ARE WORKING ON THE CIRCUIT.
The wiring diagram is located on the inside surface of the right side panel as you face the oven. Use
copper wire rated for at least 90°C for the connection.

BEFORE FIRST USE
Before using the oven for the first time, it must be "burned in" to release any odors that might result from
heating the new surfaces in the oven. Operate the oven at 480°F for 45 minutes in Convection HOT
AIR Mode. Perform CONFIGURATION MODE — PROGRAMMABLE CONTROL, pages 30 – 31.
OPERATION
WARNING: THE OVEN AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING OR
SERVICING THE OVEN. THE COOKING COMPARTMENT CONTAINS LIVE STEAM. STAY CLEAR
WHEN OPENING DOOR.
DOOR OPENING AND CLOSING
The oven door is equipped with an electrically powered lock. The oven is delivered with the door
latched and slightly open (Fig. 3) and can be opened by firmly pulling the door handle (Fig. 5). Push
the door until it connects with the latch but remains slightly open (Fig. 3). This is the position the door
should be in when the oven is not in use. The door should also be in this position after cooking to allow
steam to escape before fully opening the door. Push the handle until it is in line with the oven door.
If power has been connected, the door will now lock automatically, sealing the oven chamber (Fig. 4).
To release the door, rotate (pull) the handle 90 degrees. The door automatically releases to the
'latched and slightly opened' position. Allow a few seconds for steam to escape before pulling the door
open (Fig. 5).
NOTE: If the ON button is pushed after the oven is turned on, the door will be latched but slightly open
(Fig. 3) for three seconds; the handle can be released by rotating 90 degrees as shown in Fig. 5. If the
handle is not released within the three second interval, the door will automatically re-close.
Fig. 3
Fig. 4
Fig. 5
NOTE: In the event of a power failure, the door may be opened by pulling the handle firmly towards
you while firmly pressing against the front of the oven with the other hand (avoid hot air contact).
GREASE FILTER
The grease filter in the rear of the oven chamber should be in place when roasting meat items but may
be removed before baking items that do not produce grease-laden vapors. See Cleaning, page 27,
for information on how to remove the grease filter.

LOADING THE OVEN
Open the door. Place the product to be cooked in suitable containers and slide into the racks or place
the containers securely on shelves in the oven.
When loading a 6 or 10 level oven with the landing
table (Fig. 6), the bottom frame of the rack should
be secured by the rotary lock. Move the loaded
landing table to the front of the open oven; secure
the landing table to the oven by actuating the
locking-clamp (or use your body to hold the landing
table against the oven). Rotate the lock-knob to
release the pan rack and carefully roll the loaded
pan rack into the oven, making sure that the landing
table does not separate from the oven during the
transfer.
NOTE: When the landing table is not in use on the
6 or 10 level oven, make sure the rack retainer
(delivered with the oven) is fitted under the fan
baffle to prevent the pan rack from tilting when pans
are being removed.
Fig. 6
When loading a 20 level oven with the trolley (Fig. 7), make sure the handle is locked in the down
position so the rack is held securely to the trolley with its lifting hooks. Carefully move the loaded trolley
completely into the open oven. When the rear frame of the rack is positioned behind the edge of the
retainer, raise the handle to lower the rack-frame to the oven door.
Fig. 7

UNLOADING THE OVEN
Allow the door to be 'slightly-opened' for a few seconds to allow hot air and steam to escape. Stand
behind the door while opening.
When unloading a 6 or 10 level oven, move the landing table so the clamp locks the landing table to
the front of the oven (or use your body to hold the landing table against the oven). Remove the landing
table handles and clamp them to the bottom of the hot oven pan rack. Carefully roll the hot pan rack
onto the landing table platform, making sure that the landing table does not separate from the oven
during transfer. Rotate the knob to allow the rack to move completely to the front of the landing table;
and rotate the knob back to lock the pan rack in place.
When unloading a 20 level oven, move the trolley (Fig. 7) into the oven until the "lift-hooks" are inserted
into both sides of the front frame of the rack in the correct "lift" position. Lower the trolley handle until
it stops; the loaded rack is lifted from its retainer and held securely to the trolley by the "lift-hooks". The
trolley may now be removed from the oven with the loaded rack securely held in place.
BUZZER
When either the Cooking Time has elapsed or the final internal Probe Temperature has been reached,
the buzzer will sound [ ON for 15 seconds and OFF for 45 seconds ] until Start / Stop,
, is pressed.
If done, the product should be removed, portioned, and served. The Buzzer can be adjusted two ways:
Buzzer loudness can be adjusted by your service technician. Buzzer frequency can be set in
configuration mode (page 30).
COOL DOWN ❆
When the cooking phase is changed from a higher temperature in Hot Air or Combi Modes to
Steam Mode, the Humidifier discharges automatically. This produces steam, opens the oven
vent, and lowers the oven temperature to 212°F.
When empty after a cooking process has been completed, the oven may be too hot for the next
operation. The oven can use the Humidifier to cool itself. Cool Down can be programmed as
one of the five Cooking Phases. To perform a Cool Down, follow this procedure:

PROBE
The Probe Temperature defines the final temperature of the product for any cooking phase. The
cooking cycle stops when the product temperature reaches the probe temperature setting. Total
Cooking Time is not known or entered when using the probe.
COOKING WITH THE PROBE
There are two ways to control the oven temperature when using the Probe . . .
1) Setting the Oven Temperature at a constant value. The oven climbs to the set point and the product
cooks at that temperature. The cooking cycle ends when the product reaches the Probe
temperature setting. Or,
2) Using

program.
USING THE TEMPERATURE PROBE
The Temperature Probe is kept in a metal holder at the top of the oven when not in use. Remove the
probe from its holder; the cable remains permanently connected to the top of the oven. Insert the
pointed end of the probe so its tip is approximately in the middle of the product to be cooked. The probe
cable is long enough to allow the product to be placed on one of the upper racks in the oven. The probe
can be used to define the final temperature for any phase of the cooking process and for any of the three
cooking modes: Convection (Hot Air), Steam, or Combi.
• To set the Probe Temperature, press
and use the UP and DOWN arrows to adjust the setting.
The Cooking Time cannot be used when the Probe Temperature is in use.
NOTE: During Operator training to demonstrate use of the probe, place the probe in a container of
water to simulate cooking of actual product.

BAKING (Convection Baking – HOT AIR)
Convection Baking involves baking, browning, roasting, etc. without adding steam or moisture to the
process. Hot air is fan-circulated to maintain even temperatures throughout the oven. Preheating the
oven before loading the product is recommended.
Automatic Convection Baking can be set up so the buzzer sounds when the Cooking Time has elapsed
or when the product's internal temperature has reached the Probe Temperature set point. If using the
Probe Temperature, insert the probe near the center of the product. Cooking Time is not used when

STEAMING (Steam Mode only)
Steam cooking is used for stewing, poaching, and gentle cooking of products cooked in water. Steam
flows without pressure into the oven. The fan circulates the steam to all parts of the oven. Allow the
steam generator to preheat for 4 - 5 minutes if starting from cold. Also, it is recommended that you
preheat the oven using the Convection Baking (HOT AIR) Mode.
Automatic Steaming can be set up so the buzzer sounds when the Cooking Time has elapsed or when
the product's internal temperature has reached the Probe Temperature set point. If using the Probe
Temperature, insert the probe near the center of the product. Cooking Time is not used when the Probe
Temperature is in use.
Usually, the Cooking Time and Oven Temperature are used to control the steaming process.
Alternatively, the Probe Temperature can be used to indicate when cooking is done. When using the
Probe Temperature, either the Oven Temperature or
can be used to control the oven.
Turn the oven ON.
Select Steam Mode.

COMBI (Convection Baking with Steaming)
Combi baking / steaming is used for baking, roasting, or braising when steam needs to be added to the
oven during a convection baking operation. The 'Steam Factor' can be varied by repeat pressing of
the Combi key — see Steam Factor in the table below. It is recommended that you preheat the oven.
Automatic Combi baking / steaming can be set up so the buzzer sounds when the Cooking Time has
elapsed or when the product's internal temperature has reached the Probe Temperature set point. If
using the Probe Temperature, insert the probe near the center of the product. Cooking Time is not used
when the Probe Temperature is in use.
Usually, the Cooking Time and Oven Temperature are used to control the Combi baking / steaming

COMBI APPLICATIONS
All Applications are suggested only — prove your own recipes and temperature / time settings. Combi
applications typically begin with a Steam Mode phase which automatically preheats the steam
generator in readiness for a subsequent Combi Mode phase. Some applications contain a HOT AIR

COOK AND HOLD APPLICATIONS
All Applications are suggested only — prove your own recipes and temperature / time settings.
This two-stage process cooks roast beef or other products slowly and efficiently. During the first phase,
the oven cooks at the Oven Temperature for a set amount of time or until a Probe Temperature is
reached. When the first phase is complete, the oven heaters turn off and fan is at half speed. The
roast continues to cook as the temperature declines to the Hold Temperature, (140°F for beef). The
heaters then resume at half power, maintaining the "ready-to-serve" or Hold Temperature indefinitely.
After unloading, the oven can be used for its next cooking task or shut off manually.

EXAMPLE PROGRAM
This example shows how to program a three-phase process for cooking Roast Beef, 18 pounds per
roast, and store it as program number 20.
The second item in the table on page 21 provides most of the information: For Combi time, Phase 2,
15 minutes-per-pound times 18 pounds-per-roast equals 270 minutes (or 4 hours and 30 minutes). We
assumed that Steam Factor at 20 would be OK. We chose the average temperature when a
temperature range was given. We chose to leave the Vent Closed during phase 3. In this example,
we will not use the temperature probe. Refer to the menu card example at the bottom of page 25.

CLEANING
Daily Cleaning
Preheat the oven to 130°F and spray a mild detergent solution that does not contain chlorine on the
inside surfaces of the oven. A Spray Bottle is provided. Allow the detergent solution to react for 15
minutes.
Operate the oven on Steam mode for 15 minutes. Allow the oven to cool; wipe the oven interior with
a sponge and warm water. Dry the oven interior with a clean soft cloth.
DO NOT use abrasive products.
Clean the exterior with a cloth or sponge and non-agressive, non-abrasive products.
Complete Cleaning
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE
DISCONNECT SWITCH INDICATING THAT YOU ARE WORKING ON THE OVEN.
Remove the rack (Fig. 8). Remove the grease filter (Fig. 8) at the rear of the oven chamber by lifting
up and out. Remove the fan baffle (Fig. 9) by lifting up and out. Remove the rack retainer (Fig. 9)
normally located under the grease filter and fan baffle. Wash the removed parts in a sink with warm

Complete Cleaning (continued)
The interior glass door (Fig. 10) is independently hinged to allow both sides of the glass doors to be
cleaned. With the oven door open, pull the interior glass door away from the exterior oven door. The
snap-release fasteners should allow the interior glass door to swing free. All four sides of the glass can
be cleaned using a cloth and glass cleaner or warm soapy water and a clear water rinse. The area
between, behind, and around the surfaces of the upper and lower hinges can be cleaned by holding
both ends of a moist soapy cleaning cloth folded in a three inch wide strip and swabbing up and down;
rinse and dry with clean wet or dry cloth in the same manner. When glass is clean, push the interior
glass door against the exterior oven door and the snap-release fasteners should re-fasten the interior
glass door to the exterior glass door so it operates as one door.
Wipe surfaces which touch the door gasket with a cloth or sponge and warm soapy water, rinse with
warm clear water, and wipe with a dry cloth. CAUTION: Do not allow the door gasket to come in
contact with food oils, petroleum solvents, lubricants, or caustic cleaners.
For 6 and 10 level ovens, remove the condensate gutter (Fig. 10) by removing the two thumb screws
that attach it to the bottom of the inside of the door frame. For 20 level ovens, the three segment
condensate gutter may be removed for cleaning. Save the screws. Wash and rinse the condensate
gutter in a sink with warm soapy water and a clear water rinse, and dry with a clean dry cloth. To reinstall
condensate gutter: Reverse the removal procedure, align screw holes and tighten screws.
Keep the cooking compartment drain (Fig. 10) working freely. After cooking grease producing foods,
operate the oven with the compartment empty for 30 minutes at the end of the day, or slowly pour 1/2
gallon of warm soapy water down the drain, followed by 1/2 gallon of warm clear water. The drain grating
may be removed for cleaning; replace it in its original position when done.
Leave the door slightly open when the oven is not in use to allow the inside to dry out.
