Safety Instructions

Ready to use….

When the oven is correctly installed, read this manual carefully before the oven comes into
service.
This manual should be kept handy to persons using the oven.

Always place trays filled with hot liquid in the bottom runners of the oven chamber to avoid
spilling the hot liquid on yourself when you take the tray out of the oven chamber.

Some areas on the outside of the oven may get as hot as 60°C or more, therefore, you should
only touch the front of the oven.

Do not open the oven during the automatic cleaning process.

Do not store flammable materials around or under the unit.

When using the roll-in or trolley system, be aware of hot racks sliding out of the oven. Use the
parking brakes on the wheels to prevent trolleys from rolling away on uneven floors.

Gas units only:

If your oven is installed under an extraction hood (recommended), the extraction hood should
be switched on when the oven is running.

If your oven is connected to a chimney, the flue duct must be cleaned in compliance with local
standards and regulations.

Do not block the exhaust pipes or the area around the oven.

The oven should only be used in calm conditions.

FAILURE TO COMPLY WITH THE ABOVE INSTRUCTIONS MAY INCREASE THE RISK OF
FIRE!

If you smell gas….

- Turn off the gas supply immediately.

- Do not use the control panel.

- Make sure there is ample ventilation near the oven.

- Avoid open fire and sparks.

- Call the gas supplier, using an external phone.

Maintenance and repair:

Maintenance and repair should only be carried out by trained technicians.

Only use cleaning detergent that matches the specifications from the factory.

Quick start

The operation panel is so designed that the modes
are activated by pressing the keys next to the
symbols or digits (6 keys on either side).

In the case of for instance time and temperature,
the left as well as the right side next to the mode
are active. The right key increases time,
temperature, etc. and the left key reduces time,
temperature, etc.

Some of the symbols are shown on one side only
and will lead you to a submenu. When you have
made changes in the submenu, press OK at the
upper right hand corner.

The red circle with the green line at the top of the
panel is the main switch.

The green square with the white line at the lower
right-hand corner is ON/OFF.

The white circle with the small symbol at the
lower left-hand corner gives you access to the
programme menu.

counts down from 59 seconds. The alarm sounds when time is up. The red digits are the preset
time and temperature.

When the oven is on (a program or a function has been activated – the square around the
function flashes), it is still possible to set TIME, TEMPERATURE, FAN and EXHAUST.

Note that the fan wheel is reversible. This means that the wheel can run leftwards as well as
rightwards with a small interval when changing direction.

The core temperature should be set before the program is started.

On the following pages, the above initial display image will be referred to as the “work menu”.

* For continuous operation, press the left key until the indication of time disappears.

Fan and exhaust can be activated before as well as after start-up.

A fan speed between 20 and 50% is recommended for the baking of puff pastry, Danish
pastry, cakes and small products as well as in the Delta-T and Cook-and-Hold modes. You may
add 1 – 2 minutes’ preparation time for each ½ hour when low fan speed is used.

Fan speeds below 50% cannot be used at temperatures above 200°C.

A fan speed between 50 and 90% are recommended if you want a particularly juicy end
product and can accept a longer cooking time.

Open exhaust is recommended for bread and pastry, roasting of pieces of meat and to achieve
a grill effect.

a) Return to work menu without saving settings of fan and exhaust, if any.
b) Accept settings of fan and exhaust and return to work menu.

It is only possible to set the exhaust function in the hot-air mode. In the other modes, the
exhaust function is controlled automatically by the oven.

Core temperature

The core temperature sensor offers you the following modes:

Active: This is the mode in which you use the core temperature to determine when the
product is finished. In this mode, you set the oven temperature, the programme and, if actual,
the humidity content.

Delta-T: This is the mode in which you set the desired core temperature. You get the best
result starting with an oven temperature of 30 – 40°C. Subsequently, the oven automatically
controls the temperature in the oven chamber on the basis of the core temperature of the
product. The oven temperature is approx. 20°C higher than the current core temperature
rising gradually as the core temperature of the product rises. This mode offers you very gentle
preparation resulting in a tender and juicy end product and reducing shrinkage by up to 20%
compared to traditional modes of preparation.

Cook & Hold: Cook & Hold is an extension to the Delta-T mode. It starts like Delta-T but ends
up by evening out the temperature in the oven and the core temperature and thus acting as a
warming mode.
Cook & hold is suitable for roasting overnight when there is no staff around.

Start-up

You start core temperature sensor 1 (optional extra for CPE) by pressing the on/off key
once.

You start Delta-T by pressing once more next to the active core temperature sensor 1.

You start Cook & Hold by pressing once more next to the active Delta-T.

To switch off core temperature sensor 1, press the on/off key once more.

Remember always to confirm your setting by pressing OK on the key in the upper right-hand
corner.

You start core temperature sensor 2 (optional extra for KPE and CPE) by pressing the on/off
key once. Core temperature 2 only holds the mode “active”.

Procedure

OK for settings and
return

1. Cool down the oven to 30 – 40°C

2. Select one of the following modes:
HOT AIR, recommended for very fatty and not too large roasts.

STEAMING, recommended for large hams with bones.
REHEATING, recommended for poultry and other lean pieces of meat.
CLIMAOPTIMA 50%-80%, recommended for all other products.

3. Insert the core temperature probe in the product with the largest diameter.

4. Activate Delta-T and set core temperature. Remember to confirm.

5. Press ON/OFF

Delta-T is particularly suitable for cuts of meat that contain a great deal of connective tissue,
for large roasts and for very lean cuts of meat. During this slow preparation process, the tough
connective tissue is gently broken down, which enhances the flavour and increases the
juiciness of the finished product.

The preparation time depends on the thickness of the meat and its contents of connective
tissue, bones and fat. The recommended preparation time is 60 – 75 minutes for each kg of
meet. This means that if the oven is loaded with pieces of meat, the largest of which weighs 3
kg, the preparation time will be 3 – 4 hours.

Note that the aromatic compounds in the meat only become volatile at temperatures above
120°C. This means that the meat does not give off flavour until it has been browned at a high
temperature for a few minutes. This is, however, of no importance if the meat is subsequently
to be cut out. It may be of importance if the meat is to be carved for a buffet.

Recommended core temperatures in Delta-T:

Rare : 52 - 57°C
Medium: 59 - 62°C
Well-done: 72 - 85°C

Cook & Hold

COOK & HOLD is a Delta-T mode which, in addition, keeps the food hot when it is done.

COOK & HOLD maintains the core temperature until the program is interrupted (by pressing
ON/OFF, by opening the oven door, or when the time has run out).

Cook & Hold can be activated in HOT AIR, STEAMING, REHEATING (recommended) and
CLIMAOPTIMA.

Recommended holding temperature is 60 – 65°C (at temperatures above 60°C, a gradual
dehydration of proteins takes place, the weight of the meat is reduced and the meat becomes
less juicy).

At the above temperature, the meat can be taken out immediately before carving.

After 5 – 6 hours’ preparation in COOK & HOLD, shrinkage increases.

ClimaOptima®

Set humidity
content (lower)

When using ClimaOptima correctly, you minimise shrinkage and enhance the appearance and
taste of the products.

ClimaOptima offers you the possibility of adding up to 100% humidity to the oven chamber at
temperatures from 70 to 250°C). The computer automatically operates according to the
desired humidity content by adding or removing humidity.

Many products contain a rather large amount of water and therefore give off a great deal of
humidity during preparation. Therefore, the oven chamber often contains 15 – 50% natural
humidity.

Preheating for 5 minutes with the desired humidity content is recommended.

Depending on the amount of products in the oven and the setting of humidity and
temperature, the correct humidity content has been reached after 1 – 5 min.

Blue bar is the actual amount of humidity in oven chamber
White digits are the humidity set
If bar is all red, oven chamber contains 0% humidity.
If bar is all blue, oven chamber contains 100% humidity.

If you want dry air for grilling, for instance, apply 0% humidity at 200 – 250%C

To produce gravy when braising meat, apply 70 – 80% humidity at 145 – 165°C.
For poaching fish, poultry and crispy vegetables, apply 70 – 95% humidity at 70 – 120°C.
For steaming potatoes, rice, pasta, meat, etc., apply 100% humidity at 100°C.

Set humidity content
(higher)

For quick preparation, we recommend the following combination: 190°C – 70%
humidity.

Despite the short time of preparation, products such as herb-marinated cuts of meat, fresh
vegetables and bread are treated very gently.

If the oven is not connected to a soft water plant, ClimaOptima cannot function
properly.

CPE/KPE – Ver. 1.54x – July 2009

13

Steaming

To get the oven ready for production quickly and to
ensure a perfect start of the steaming process, we
recommend that you cool down the oven chamber to
80°C.

If the oven chamber is too hot, it cools down auto­matically. It is faster to use the cooling mode, as this
mode allows you to open the door while the mode is
active.

We recommend that you start the steaming process 8
minutes before you place the products in the oven
chamber.
For reasons of hygiene, the oven automatically checks
the water in the steam generator. If the water
temperature is below 65°C, the tank is emptied, refilled
and the water is heated.

Low-temperature steaming at 65 - 90°C is
recommended for delicate products such as fish.
Steaming at 80°C for 5 – 10 min. of small, fresh
vegetables such as carrots, asparagus, and beans
(diameter: 5 – 12 mm) produces end products that
keep their colour and crispness.

Traditional steaming at 98 – 100°C is recommended
for all kinds of root vegetables, potatoes, pasta, rice and
meat.

Forced steaming at 120°C can be used for vegetables
that need further processing and for faster preparation
of for instance pasta, rice, hard root vegetables and
frozen vegetables. Forced steaming should be used with
care.

To achieve a perfect result every time, we recommend
the use of the core temperature probe in all steaming
modes.

In a CPE model, you boil by means of injection steam.
Select ClimaOptima with 100% humidity at 100°C.

If the oven is not connected to a soft water plant, the steaming modes cannot
function properly.

CPE/KPE – Ver. 1.54x – July 2009

14

Cook & Regen

Cook & Regen is a very gentle process (20 – 180°C).
The program operates with low fan speed and adds a
carefully calculated amount of humidity which
maintains the nice appearance and taste of the
products.

To get the fastest regeneration, the products should not
be covered with a lid or the like.

Use a core temperature probe to reach a perfect end
temperature.

For the regeneration of sous-vide products, etc., follow
the recommendations of the supplier.

Recommended times and temperatures for fast reheating:

8 – 12 minutes at 140°C for rice/meat and vegetables arranged on plates
40 – 60 minutes at 120 – 140°C for whole roasts, stews and sauces
20 – 30 minutes at 120°C for pasta, rice and the like

Proving/Rising

The computer is set to maintain the perfect humidity for
all products that need to be proved before they are
baked.

Recommended settings of temperature and time:
Loaves of 400 – 800 g: Low temperature and long
proving time (32°C, 45 min.).
Rolls/baguettes of 60 – 200 g: High temperature and
short proving time (36°C, 25 min.).

We call your attention to the preset ”semiautomatic
bread program”, in which the bread is proved and baked
in the same process (models KPE, CPE and BPE).

Please note the distinction between prebaked (additional
baking only) and preproved (defrosting, proving and
baking).

CPE/KPE – Ver. 1.54x – July 2009

15

Preheating

PREHEATING ensures that the oven chamber is
thoroughly heated.
If the oven is cold, 2 - 5 minutes’ preheating is
recommended (models 2.10 and 2.14 require 15
minutes’ preheating)
If the oven is hot, 0 – 2 minutes’ preheating is
recommended.
Preheating at a temperature which is approx. 50°C
higher than the desired working temperature is
recommended.

NOTE: When the oven door is opened for loading, the

oven chamber loses 30-50% of the heat.

PREHEATING can be set at 0 – 15 minutes

.

Note that the countdown does not start until the
selected oven temperature is reached.

Cooling

Cooling is used if you need the oven chamber to be
cooler, for instance, when you switch from roasting to
steaming or if you are about to clean the oven.

Cooling is activated in either of the following ways:

a) Oven door closed. Water is used to speed up the

cooling process. Alarm sounds when the
temperature is reached.

b) Oven door open. Fan wheel draws in air to speed

up the cooling process. Programme stops when the
temperature is reached.

It is recommended to set the cooling mode at 20°C
below the desired working temperature.
