Introduction
In the SVEBA-DAHLEN oven series C, the hot air is circulated by fans and the rack carrying the product to be baked
rotates during the baking process.
The oven can be delivered in three different ways of heating: electrically, oil or gas.
Oven type C100, C150, C200, C250 - electrically heated
Oven type C101, C151, C201, C251 - oil heated
Oven type C102, C152, C202, C252 - gas heated
Natural gas, city gas or propane gas can be used. Indirect heating through heat exchanger to maintain high demands
of function and security.
The ovens have a steam system, which is connected to a standard water supply. The amount of steam is controlled
by means of a timer on the instrument panel.
The oven door incorporates interior lighting and has a large glass panel giving a convenient view of the interior of
the oven.
The oven is delivered with hook for suspension of the rack in the oven ceiling. As an option rotating platform and
automatic rack lifting device are available. When the oven door is opened the suspension device stops. Possibility
to adjust the stop position.

Product description
Air system
The hot air circulated by fans, enters on the left-hand side of the oven and is drawn out on the right-hand side. The
amount and direction of the air can be adjusted by means of adjustable air slots. Instructions for adjusting the slots
are given in the section headed ’Settings of air slots’.
Rotation
The mounting hooks and rotating plate with the rack unit are driven by an electric motor placed in the right-hand
section behind the hood. The power transmission to the rotating shaft is by means of a V-belt.
Steam system
The production of all the steam is conducted in the steam package, and therefore only cold water needs to be
connected. The steam package is placed in the left-hand air duct.
The water supply is conducted through sprinkler pipes with holes. The water pressure is 4-6 bar.
The pipe for the drain water comes out in the front left-hand corner of the oven.
Heating Gas / Oil
Heat is transferred to the oven via a heat exchanger mounted in the roof section.
Several makes of burner may be used. If the oven comes with a factory-fitted burner, operating and servicing
instructions are provided in the SERVICE folder. Read them carefully!
Every burner fitted must be set for the correct output and operation in accordance with the technical data.
See 'Installation'.
Electrical connection
The oven is fitted with built-in automatic fuses, placed in the control box. The fuses are marked and can be accessed
when the control box door is opened.
Ventilation
The ventilation around the oven has to be controlled so that the ambient temperature of the oven does not exceed
50 °C. Measure the temperature above the roof of the oven.
Oven exhaust
The damper to be connected to an exhaust duct with ventilation breaker. See 'Installation'.
Please note that a too strong draught can influence the baking results negatively.
Noise
Emission of airborne noise is below 70dB.

Settings of air slots
In the oven chamber there are four air slots which have been accurately adjusted before the delivery. Through these
slots hot air passes to give a uniform baking result. However, factors outside the oven can negatively influence the
results: The damper setting, or a combination of racks, trays and goods to be baked. An adjustment of the air slots
may be necessary. However, before such an adjustment is made please consider the following.
Have a couple of batches made with the same product to ascertain that the failure was not due to something else in
the baking procedure.
Do not have any adjustments of the air slots made unless you feel sure the uneven baking really depends on the oven.
A sudden change of the baking results can depend on something quite different.
Check that the fan motors run correctly and that no adjustment plates have come loose.
If you feel sure an adjustment is required, start by reducing the air gap located on a level where the goods have been
coloured at the darkest.
Reduce the air gap for one louvre at a time and with one millimetre at the most for each adjustment.
If too big adjustments are made on each occasion there is easily the possibility that the entire operation will go
beyond your control. In such a case you will have to start from scratch again with all the louvres adjusted as per the
basic settings.
If the above instructions would fail to give the wanted results you have to reset the louvres to the basic settings as
shown here. Then start again and now by increasing the air gap for the louvre located on a level with the goods being
the least coloured.
Please remember to make changes for one louvre only at a time and by just one millimetre.
Setting of air slots is simplified by using our gauge with templates from 3 - 24 mm.

Maintenance
Cleaning
In order that the oven will work without problems and give the best baking results it has to be cleaned at regular
intervals. For hygienic reasons the oven chamber should be cleaned at the end of each working day.
Be cautious as sharp corners and edges can be found.
Minor service work should be carried out regularly. See 'Service' instructions.
Cleaning oven exterior
OVEN CLEANER is an appropriate detergent for glass and inside of the oven. It can be purchased directly from
Sveba-Dahlen, Art. no. 80073-02. Do not use alkaline or abrasive detergents! Sveba-Dahlen has an excellent
detergent for the exterior of the oven: LAHEGA, Art no. 91430-009. For final cleaning of the glass we recommend
BRITE GLAZE, Art. no. 91430-005. Call us on phone number +46 33 151500 or fax us on fax number
+46 33 151599
Don't use high-pressure cleaning
Water fittings
The water to the steam package passes through a filter in the left-hand section. The filter must be cleaned at regular
intervals. Turn off the main tap, unscrew the filter, and clean it. Screw the filter back on and tighten well. Open the
main tap and check that there is no leakage.
In areas where the water has a high content of lime the sprinkler pipe may become blocked. Unscrew the pipe in the
left-hand section, and clean it.
The electrical box
Before any work is carried out, the main current of the oven has to be switched off.
Clean all the cables, wires and electrical components with a soft brush or by means of a vacuum cleaner once a year.
Close the box before switching on the main switch.
Cleaning of burner
For service, cleaning and maintenance of the burner please contact an authorized expert company. We recommend
that you make an agreement with this company about a schedule to come at regular intervals for inspection and
service of your burner.
Replacing the chamber lighting
Switch off the power!
Open the outer right panel. Unscrew the screws from the fluorescent tube's guard plate and then remove the tube from
the holders. Dismantle the terminal blocks from the tube. Fit a new tube in the reverse order.

Avoid too many and/or sharp elbows.
The connected chimney must not rest on the exhaust connection or oven top.
Initial burning-off procedure
Every new oven must be burned-off before it is used, to remove protective grease and excess oil, so that the smoke
from these does not affect the baked products. The oven will give off some smoke at first during this process. Make
sure of sufficient ventilation during the process.
Set the thermostat to 250 °C and leave the oven on for at least two hours.
Setting the air slots.
The air slots are given an initial basic setting at the factory. The operating instructions explains how to adjust them.
However, after the burning-off procedure, the louvres must be checked.
