1. Introduction
Notes on Technical Dimensions and Installation Planning of the Atoll Speed
Micro-Convection Oven.
When planning the installation of the Atoll Speed, make sure that the installation side
(especially the right side) is permanently accessible. When planning the installation
of an Atoll Speed in a wall recess, keep free the following spaces around the baking
oven.
Left side: Minimum 50 mm
Installation side: Minimum 50 mm
Rear side: Minimum 110 mm
Upper side oven cover: Minimum 150 mm
If a front casing up to the baking oven edge is required, provide this casing with an
easily detachable faced frame.
If this front casing is to be supplied and installed by a shop equipment company, the
above information has to be taken into account.
During installation and arrangement of the baking oven, make sure that no damages
can be caused by the operation of the baking unit and its charge and discharge
pipes, particularly through the effect of heat. You must pay attention to the required
distances and insulations.
If this baking oven is installed near walls, partitions, kitchen furniture, ornamental
furnishings etc., we recommend that these are made of fire-proof material.
Otherwise, they must be encased in suitable non-inflammable material. Fire safety
instructions must be carefully observed.

Wait at least 30 minutes before you start to clean the inside baking chamber
and make sure that it is not hot any more. Otherwise wait longer.
This oven can only be used to head up food.
Never use the micro-wave function if the baking chamber is empty. There
should always be any liquid or any suitable food in the baking chamber when
the micro-wave function is initiated.

when heating food in plastic or paper containers, keep an eye on the oven
due to the possibility of ignition;
If smoke is observed, switch off or unplug the appliance and keep the door
closed in order to stifle any flames;
Eggs in their shell and whole hard-boiled eggs should not be heated in
microwave ovens since they may explode even after microwave heating has
ended;
When preparing frozen food defrost with maximum 20% Microwave power to
ensure good heat distribution and avoid damage to the device.
3. Oven Installation
1. Remove packing material from the oven and put the material in the wastage bin or
recycle.
2. The oven has to be set up on an even and flat surface and may not be exposed to
any vibration. Two or more people are required to lift the oven. Don’t lift the oven at
the door handle or the door. The surface place must be able to hold the weight of at
least 150 kg.
3. Open the cooking chamber door and take out all the material inside the oven
chamber. Thereafter remove the protection film from all the parts before starting the
first heating up process. The chamber must be clean before using the oven.
4. Check the oven for visual damage. If you find any damaged parts, inform the
installation engineer or the agent.
3.1 Electric connection
Please note that all adjustments to the Atoll Speed (connections,
repairs maintenance work etc.) should be carried out only by
licensed specialists who are familiar with the valid and local
general regulation.
The electric connection cable must be flexible. It must be in loops
so that the baking oven can also be relocated even when it must be
moved forward for the installation or rear side for inspection
reasons.
Supply lines and fuse protection must be installed to the list. A master switch
provided by the customer is to be fitted into the supply line (all-pole connector).
For the standard type, the electric connection is carried out via a plug connector.
The master switch is not necessary if the connection is made via a plug connector or
an outlet.
If the Atoll Speed is installed as a dual-circuit oven (which means that the units are
double stacked), each baking unit required a separate electrical connection of 16 A
each.

The residue Current switch must be rated 30mA or more.
Do not plug other devices together with Atoll Speed to the same connection. Do not
use Multi Plug connectors. Risk of cable burns!
Extension lines must be rated to 16A and have the according wire strength (3 x
2,5mm²).
"Dangerous voltage —to indicate hazards arising from
dangerous voltages. Note In case of application in a warning sign,
the rules according to ISO 3864 shall be adhered to."
If there is no equipotential bonding conductor in the electric supply, an
external equipotential bonding conductor must be installed at the rear of the
appliance (see symbol).
3.2 Start the oven for the first time
After the Atoll Speed has been properly connected, the following points must be
accomplished:
Check if the oven has any outside damage. If you see any damage STOP at
this point and contact your reseller or Kolb.
The oven has a safety temperature limiter. This can be triggered from
vibration during transport. The result is that the oven does not heat up. So it
maybe necessary to reset the Safety Temperature limiter before the first start
up. Therefore remove the small cover at the bottom of the oven backside and
press the red button hard.
The baking chamber must be cleaned first with a wet towel. Then heat up the
oven to 260ºC and keep this temperature for 30 min. ATTENTION! The oven
can be only heated up without micro-wave function

5. Why is the cooking speed so fast?
The Atoll Speed produces a combination of high speed forced air convection heating
and microwave energy to cook food.
Due to the combination of several technologies baking and cooking with the Atoll
Speed is much faster than with conventional convection ovens.
The high speed of circulated air, combined with microwave energy assures a very
fast heating/cooking process. The exterior of the food will be crispy and the inside
will be warm. With this technology you can serve your customer faster and obtain
the same taste as fresh baked/cooked food.
