RECEIVING & TRANSPORTATION

Upon receipt of the Combitherm combination
oven/steamer, check the exterior of the shipping
carton for any physical damage that could result in
damage to the contents. If the oven was not
received from the carrier in an upright position,
there is a stronger possibility of concealed damage.
Remove the carton or uncrate the unit carefully
and inspect for any transit damage. Immediately
report any damage to the delivering freight carrier.

The oven must remain on the pallet

while being moved to the installation site

by fork lift or pallet lift truck.

Note the dimensions required for doorways and
aisles for access of the oven and pallet to the
installation site. Transport the oven in an upright
and level position only. Do not tilt the oven.

With the oven on the original pallet, remove the
carton and all packaging materials. Open the oven
door and remove all documents and other
materials from the oven interior. Remove the
roll-in cart if so equipped.

IMPORTANT SAFETY PRECAUTIONS

For safe release of the cooking

compartment steam, initially

open the door approximately

2" (50mm) only. Stand

behind the door as the hot

steam is released.

STEAM

DO NOT USE THE ATTACHED HAND-HELD HOSE TO SPRAY ANYTHING OTHER

THAN THE INTERIOR OF THE COMBITHERM OVEN COMPARTMENT.

AT NO TIME SHOULD THE EXTERIOR OF THE OVEN BE STEAM

CLEANED, HOSED-DOWN WITH THE HAND-SPRAYER, FLOODED WITH

WATER, OR FLOODED WITH LIQUID SOLUTION OF ANY KIND.

DO NOT USE THE SPRAY HOSE IN A HOT COOKING COMPARTMENT. ALLOW

THE OVEN TO COOL TO A MINIMUM OF 150°F (66°C).

DO NOT USE HIGH PRESSURE WATER CLEANING METHODS ON THE INTERIOR

OR EXTERIOR OF THE COMBITHERM OVEN.

DO NOT HANDLE PANS CONTAINING LIQUID OR SEMI LIQUID PRODUCTS

POSITIONED ABOVE EYE LEVEL OF THE OPERATOR. SUCH PRODUCTS

CAN SCALD AND CAUSE SERIOUS INJURY.

USE AUTHORIZED COMBITHERM LIQUID 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.

FOR OPERATOR SAFETY

NOTE AND OBSERVE ALL SAFETY PRECAUTIONS LOCATED THROUGHOUT THIS MANUAL.

20•20ML COMBITHERM ELECTRIC INSTALLATION AND MAINTENANCE MANUAL

PG. 13

Preventive Maintenance

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.

●

DO NOT DISPOSE OF GREASE, FAT, 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 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, REMOVE AND 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.

●

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.

Routine Cleaning Requirements

DAILY OVEN CLEANING

To be performed at the end of each production day or between production shifts.

DAILY STEAM GENERATOR FLUSH

When operating the oven on a regular basis, the steam generator must be flushed once a day. This

procedure will prevent lime deposits and scale build-up from forming in the steam generator.

MONTHLY DECALCIFICATION

It is VERY important to decalcify the steam generator, particularly in areas with extremely hard water. This

procedure should be performed once a month, in addition to the daily steam generator flush.

COMBITHERM®CLEANING & MAINTENANCE

20•20ML COMBITHERM ELECTRIC INSTALLATION AND MAINTENANCE MANUAL

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 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

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.

3. As the water continues to flow

from the generator, it will have

a milky or cloudy appearance,

which indicates deposits in the

generator system are beginning

to flush out. Let the water

continue to drain until the flow

completely subsides. Replace

the Steam Generator Drain Cap
 by turning it clockwise until

there is a slight resistance.

4. Unscrew the cap from the

Decalcification Port . With

the use of a funnel, pour

one-half gallon (c. 2 liters) of

distilled white vinegar into the

Decalcification Port.

5. Replace the cap on the

Decalcification Port



and tighten securely.

Scalding water will erupt from the Decalcification Port  when

the oven is operating unless the cap is replaced and tightened.
