WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY

AND PLUMBING CODES.

WATER REQUIREMENTS

Water Requirements

Proper water quality can improve the taste of the
food prepared in the steamer, reduce liming in the
steam generator and extend equipment life. Local
water conditions vary from one location to another.
Ask your municipal water supplier for details about
your local water supply prior to installation.

Supply Pressure 20 — 60 psig
Hardness* less than 3 grains
Silica less than 13 ppm
Total Chlorine less than 4.0 ppm
pH range 7 — 8
Undissolved Solids less than 5 microns

* 17.1 ppm = 1 grain of hardness

Presence of sediment, silica, excess chlorides or other dissolved solids may lead to a recommendation
for alternate form(s) of water treatment. Test the water with the test strip included with the combi oven.
Other factors affecting steam generation are iron content, amount of chloridation and dissolved gases.
A local water treatment specialist should be consulted before installation of steam generating
equipment.

Water Supply Connections (Fig. 2)
A water filter system is recommended for the water supply line going to the treated water inlet of your

oven. Follow the recommendations for use and installation instructions shipped with the water filter.
If a water filter is not installed, the oven warranty may be limited.

Connect treated potable water ( must be cold) to the inlet labeled for treated water to supply the steam
generator tank. 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.

Both external-threaded nylon inlets

3

/4" hose bibb (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 60 psig.
Refer also to CLEAN CYCLE DELIMING PROCEDURE, page 38.

Drain Connection

ELECTRIC SUPPLY CORD

Fig. 2

CAUTION: In order to avoid any back pressure in the oven, do not connect solidly to any drain
connection.

The drain connection, 1

1

/2" NPT threaded fitting, is located underneath the oven at the rear. The drain
line must be plumbed 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. The open drain should be located between 3 and
5 feet away from the perimeter of the oven to reduce potential damage from moisture-corrosion. The
drain line from the oven must not be combined with any drain line from another device.

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 open" position. Allow a few seconds for steam to escape before pulling the door
open (Fig. 5).

NOTE: On Programmable Controls 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. A separate Door Open button will perform the same function with Manual
Standard or Deluxe Controls. On stacked ovens, the lower oven's handle does not rotate. To open,
press the ON button. When the door opens (Fig. 3), pull the metal handle located on the top of the door
to fully open the oven door.

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. For information on how to
remove the grease filter, refer to Cleaning (page 32).

BUZZER

When either the Cooking Time has elapsed or the final internal Probe Temperature has been reached,
the buzzer will sound until
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 for the type of control furnished with

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 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 while 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
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.

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 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 while 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.

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.

2) Using

is used to show how the oven works and is not typical of any particular cooking

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.

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
the Probe Temperature is in use.

If using the Probe Temperature, either the Oven Temperature or
during baking. If using the Oven Temperature setting, the oven temperature will remain constant
throughout the convection baking operation or phase. If using the Probe Temperature,

STEAMING (Steam Mode only)
Steam Mode will not begin if cavity temperature is above 212°F (100°C).
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 to 5 minutes if starting from cold.

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

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: UNPLUG THE ELECTRICAL POWER CORD.

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
soapy water, rinse with clear water and dry with a clean dry cloth.

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. Alternatively, clean the glass surfaces with soapy
water, rinse with clear water and dry with a clean cloth. 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 3" 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:
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
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 10 level ovens, remove the drip tray (Fig. 10) by removing the two thumbscrews that attach it to
the bottom of the oven. For 20 level ovens, the three segment drip tray may be removed for cleaning.
Save the screws. Wash and rinse the drip tray in a sink with warm soapy water, rinse with clear water
and dry with a clean cloth. To reinstall drip tray: Reverse the removal procedure, align screw holes
and tighten screws.

Clean the Condensate Gutter as necessary using a cloth with warm soapy water. Rinse with a clean
cloth and fresh water and allow to air dry.

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.
