Overview of functions
a b c
a Solenoid valve K12 c Pump G24 b Pump G16
The following purification stages are available on the fully automatic cleaning WaveClean:
• Short: duration of about one hour
• Normal: duration about two hours
• Extra: duration approximately three hours
Description 1. Testing the cooking chamber temperature.
Automatic cooling of the cooking chamber, if > 55°C.
2. Inserting the WaveClean cartridge.
3. Water exchange of siphon content by the siphon pump G24 and solenoid valve K12.
4. Circulation of water by means of pump G16. Thus pre-cleaning of the cooking chamber. Then anew siphon water exchange.
The heater heats the oven to 55°C.

5. Start cleaning.
Fan motor and WaveClean pump G16 active.
Heating active. Heating the cooking chamber to about 70°C.
The first layer of wax melts in the WaveClean cartridge. The cleaner falls into the cooking chamber and mixes with water.
The fan motor operates in both directions of rotation and at different speeds.
The cleaning phase duration depends on the selected program.
6. A new water exchange of siphon content by means of the siphon pump G24 and solenoid valve K12.
7. Start of rinsing.
Identical to step 5 (cleaning).
Differences: Heating of the cooking chamber to 92°C. The second layer of wax melts in the WaveClean cartridge. The rinse agent drops into the cooking chamber and mixes with water.
Final rinse to bring the pH value to the normal level.
8. In the programs "normal" and "extra" additional drying of the interior occurs by means of hot air.
9. Finally, an indicator for withdrawing the WaveClean cartridge appears, and has to be confirmed.
INFORMATION
Despite different cleaning durations, all cleaning steps require the same
amount of water.
During the cleaning process about 3 liters of water are provided by the steam-
ing unit into the oven.
WaveClean termination
INFORMATION
WaveClean forced rinsing
The WaveClean forced rinse is automatically started by the operator in case of
failure or premature termination. The duration is 12 minutes. An entry is made
into the HACCP and in the diagnostic memory.

5.7 100°C + KT calibration (CAL)
Description
Calibration for cooking chamber sensor and core temperature sensor.
Testing the calibration.
Performing the calibration.
The cooking chamber sensor and core temperature sensor calibration is performed in one step.
INFORMATION
The units are factory calibrated. Recalibration is required only in exceptional
cases.
5.7.1 Check calibration - single chamber 6.x / 10.x
Requirement Calibrated temperature digital meter.
The temperature in the cooking chamber is < 100°C.
Fixing the internal core temperature sensor and temperature sensor from the external instrument in the cooking space.
For this purpose, use a grill.
Align the sensor tips upward in order to avoid measuring errors.
Overview
96.6 -0.5CAL
Testing the calibration
Press the "START STOP" button.
The cooking chamber is heated to 100°C.
Display on the left shows the current temperature in the cooking chamber.
Wait until the display to the left indicates 100 °C (± 1°C).
Compare the left display with temperature on the external meter.
The external meter must indicate a temperature between 99°C
- 99.5°C.
If the value is within the range, terminate checking.
Press the "START STOP" button.
If the value is outside the range, calibration is carried out.
Continue with calibration (see „5.7.3 Calibrate cooking

INFORMATION
A separation into two regions (chambers) is required for temperature measure-
ments. This can be achieved, for instance, by placing a baking sheet on the
middle shelf of the tray trolley.
Prerequisite Two calibrated digital measurement devices or two-channel
measurement device. The temperature in the cooking chamber is < 100°C.
Fix the temperature sensor of the two external measurement devices in the middle of the top and bottom chambers in the cooking chamber respectively. Fix the core temperature sensor in the middle of the bottom chamber.
Use a grill rack for this.
Point the sensor tips upward in order to prevent measurement
errors.
