to remove all residues of substances that might be present in tubes, so that they
do not enter solenoid valves.
NOTE:
To provide for proper functioning and prevent limescale deposits in the
oven chamber, the appliance should be supplied with potable water, with
hardness of 0.5–5 ° dH (German degrees). With higher values it is
necessary to install water softening system.

WARNING!
Risk of burns!
During operation, the housing and glass pane door become very hot
and remain hot for a while after switching the appliance off.
Do not touch the appliance during operation nor immediately after
switching it off. Open and close the convection oven using the glass pane
door handle only.
To operate the appliance, use handles and elements designed to this end.
The grate, the tray and containers heat up considerably during
operation.
For removing hot food use dishwashing cloths or kitchen mitts.
Preparation of the Appliance
1. Prior to operation, clean the appliance and its equipment inside and outside
according to instructions in section 6“Cleaning”.
2. Prior to first use, and observing instructions in section “Settings”, heat up the
oven without food to eliminate any unpleasant odours that come from the
thermal insulation. Select the highest temperature and the longest time.
A small amount of smoke or unpleasant odour may be produced. This is normal
during first use and should not recur.
3. Next, open the glass pane door to allow all the smoke to escape.

Settings
The convection oven is controlled with two push/rotary control knobs:
–Push/rotary time control knob (at the left side of the control panel)
–Push/rotary temperature control knob (at the right side of the control
panel)
The push/rotary control knobs are used for setting time and temperature, as well as
for activating the program mode.
The push/rotary control knobs are integrated with digital displays that allow reading
the set time and temperature.
Indicator lights evidence the operating modes.

Time setting
The duration of work of the appliance is set with the push/rotary control knob (at the
left side of the control panel). Time may be set in 1-minute increments and in the
range of 1 - 120 minutes.
Temperature setting
Temperature is set with the push/rotary control knob (at the right side of the control
panel). The temperature may be set with 1 °C increments in the range of 50 °C –
300 °C.
Normal operation

4. To start the program, press the push/rotary control knob.
The heating, interior lighting and fan motors are all switched on.
The indicator light of the push/rotary control knob starts to blink.
The indicator light of the temperature control is lit as long as the set temperature is
reached; then, it is lit only during the re-heating process.
During operation, you may freely adjust both time and temperature through rotating
the respective push/rotary control knobs.
Signal tone is heard after expiry of the set time. It is repeated until it is confirmed
with pressing of one of two push/rotary control knobs. The indicator light of the
push/rotary control knob goes off.
Then, the appliance is again in the main menu.
The digital displays show the recent values used, and the indicator lights are off.
When the appliance is in Standby mode (digital displays and indicator lights of both
push/rotary control knobs are off), it may be activated by pressing one of the
push/rotary control knobs.

Cooking/Roasting Process With Fan-Forced Air Circulation
The cooking/roasting process is obtained with the use of hot air circulation inside
the appliance. This makes homogeneous cooking/roasting possible thanks to
uniform temperature distribution.
The benefit of the convection oven is the fact that you may cook/roast various foods
(provided the temperature of processing is the same), and different aromas of the
foods do not mix.
1. Introduce the temperature and time settings required for the selected food
according to the instructions in the 'Settings / Normal Operation' section.
Food Preparation
NOTE!
Prior to each use, heat the convection oven properly. Set the temperature
approx. 30°C above the required temperature and correct it when food is
put into the oven in order to obtain uniform effect.
1. When the set temperature is reached, put the food into the thermal processing
chamber on sheets.
At a time, 4 baking sheets on 4 guide rails of the convection oven may be
inserted. During loading of the appliance, make sure that there is a top
clearance of at least 40 mm between dishes and baking sheets, which will allow
for maintaining optimum heat distribution in the thermal processing chamber.
2. If needed, set the time and temperature again.
3. To continue the thermal processing, press the rotary push timer controller.
When the set time elapses, the acoustic signal sounds, which is repeated until it is
confirmed by pressing one of the two push rotary controllers.
The time indicator light of the push rotary controller goes off.
When opening the glass pane door, the heater and fan motors do not switch off.
The thermal processing can only be interrupted manually by pressing the rotary
time controller again or after the set time has elapsed.
4. Remove the sheets with the prepared food using heat-resistant protective
gloves.
5. When the appliance is not to be used any more, it should be switched off with
the ON/OFF switch.
6. Disconnect the appliance from mains power supply.
