DynaSteam Features
➢The pcb controls the DynaSteam unit which is responsible for the amount of injected water
The incoming water flow pressure must be between 1,5 (21,75 psi) and 6 bar (87,00 psi) The
pressure switch controls the availability and the pressure of water (Only at units with
WaveClean)
➢The water runs now through a hose to the water supply pipe located in the chamber Inside the
hose is an orifice to stabilize the pulsed water flow from the DynaSteam unit
➢The water supply pipe injects the water on an centrifuge at the PHI fan wheel The heating
elements surround the fan wheel heats it up The water gets to steam now and by the speed of
the fan wheel tiny drops are flung against the chamber Surplus water runs into the drain
➢During heat up and after opening / closing the door during operation the steaming unit
increases the amount of water to speed up the steam production (controlled by the electronic)
➢At a temperature of more than 107°C (225°F) the steaming unit decreases the amount of water
(electronic controlled)

Step Description
01 - Depending on exit temperature the chamber cooling down to 55°C (131°F)
02 - Cleaning of the siphon by water exchange The pump M24 pumps out the water from
the siphon The siphon gets filled with water about the solenoid valve Y12 This
process recurs repeatedly This process serves for cleaning the siphon
03 - Double pre-cleaning of the chamber by changing the water radically above pump
M16
04 - Cleaning starts after a time of 6 minutes The chamber heated at the same time The
cleaner activates at a temperature of 70°C (158°F) A cancellation of the cleaning
process is not possible in this phase!
05 - Execution of cleaning The fan runs in right/left direction The pump M16
permanently changes the water radically The running time depends on the chosen
cleaning program
06 - Cleaning of the siphon by water exchange The pump M24 pumps out the water from
the siphon The siphon gets filled with water about the solenoid valve Y12 The
process recurs repeatedly This process serves for cleaning the siphon Fresh water is
changed radically over the pump M16 to rinse the chamber The fan runs in right/left
direction
07 - The chamber heats up to 92°C (198°F) The rinse wax layer smelting now The rinse
granulate falls into the chamber now A cancellation of the cleaning process is not
possible in this phase!
08 - The rinsing program starts The fan runs in right/left direction The pump M16
permanently changes the water radically The running time depends on the chosen
cleaning program
09 - Cleaning of the siphon by water exchange The pump M24 pumps out the water from
the siphon The siphon gets filled with water about the solenoid valve Y12 This
process recurs repeatedly This process serves for cleaning the siphon Fresh water is
changed radically over the pump M16 to rinse the chamber The fan runs in right/left
direction
10 - The oven starts in steam mode for four minutes to prepare final rinsing After this the
final rinsing starts
11 - The chamber dried with hot air for 10 minutes Thereby the chamber heats up to
105°C (221°F)
When cleaning with "short-program" this step is skipped.
12 - The device turns off itself now Cleaning is finished
Note:
During cleaning approx 3 litres of water are led through the soft water assembly group to rinse out
possible cleaner delays
At an interruption of the power supply the cleaning process stopped automatically A cancellation
program which rinses out the cooking chamber is started with a duration of 12 minutes
This program is carried out also at a manual cancellation

Gas technology
Basics of the gas technology
Operation of the gas burner:
The electronic (pcb) gives a heat demand (relay K14 and K15) to the burner control
The electronic (pcb) regulates the speed of the gas fan and supervises these
The complete igniting process is handled by the burner control
At a failure of the flame signal from the burner control to the electronic the appliance is
nevertheless ready for use There is an electrical failure of the signal which safety-related is
quite safe as long as no alarm is reported (The burner control has recognized the flame (In this
case there is "just"an error to transmit information to the electronic The burner control itself
has already detected the flame)
Functional diagram

Service manual
The gas fan
The gas fan promotes the air-/ gas mixture into the burner The promoting volume and the performance
are dependent on the speed of the gas fan This is steered and supervised by the electronic The speed
only can be changed in a defined speed window which is dependent on the kind of gas and unit size
The speed window is basis of the equipment admittance and may not be changed This regulation
ensures that the gas fan speed works independently of outer influences (temperature and supply
voltage)
Fan speed control:
The gas fan is / are controlled by a PWM signal (pulse width modulation) from the electronic A2,
terminal X8 2 (6 x, 10 x, lower chamber at 20 x) and terminal X8 4 (upper chamber at unit size 20 x)
Without PWM signal and with available supply voltage the gas fan runs for safety reasons with full
speed The gas fan transmit the fan speed to the electronic A3, terminal X5 2 (6 x, 10 x, 20 x lower
chamber) and terminal X5 5 (only 20 x upper chamber) as a re-registration The gas blower is
regulated on set rotation speed by a software regulator This can be checked with the help of the
configuration menu (service menu)
A speed fluctuation up to 50 rpm is normal

Service manual
The ignition electrode
The ignition electrode serves to ignite the gas/air mixture and is supplied by a separate transformer
The flame control
The flame control induces an ionization current (approx 5 µA) after the igniting process and passes
this to the burner control If this confirmation is not available, the error message Err 71 (no gas)
appears and a reset of the burner control is necessary
The overlap-time
A sufficient overlap-time is important to ensure for a safety ignition process This time can be
controlled in the generally measurement mask
When heating request of the temperature regulator is available, the display changes from G0 to G1
At first F0 is still shown because there is no flame detected At latest after 7 seconds F1 must be
shown on display, otherwise appears the error message Err 71 (no gas)
If the "flame OK" signal is permanently not available the unit goes into an emergency program,
because there is no safety risks represents
In this case F0 does not change to F1 into the measurement mask, even though the flame is present
(The unit heats up) There is only a risk / error, if within the heat demand (active operating) the "flame
OK signal" changes repeatedly from F1 to F0

CO2 value calibration
6 x–20 x Gas
Basics
Definition of CO2 (carbon dioxide) and CO (carbon monoxide):
Carbon dioxide is a colourless and odourless gas and supplies a chemical union made of carbon and
oxygen Carbon dioxide arises at the burning of substances containing carbon (gasses) if enough
oxygen is available At an oxygen deficiency CO (carbon monoxide) arises CO is a color- and
odourless, poisonous gas which can lead to death!
CO2 value calibration

Service manual
After measuring the CO2 value at maximum power
switch the units to low power (Lo, Lo1; Lo2)
The upper display shows CO2
Turn the lower knob to Lo, Lo1 or Lo2 and press
the FLEXI button to activate the low power mode If
the FLEXI button is not pressed within 5 seconds
the prior mode is still active
The lower displays shows Lo, Lo1 or Lo2
The rpm´s of the gas blower shows the values
according to the rpm table
The CO2 content at low power has to be 0,5-1% lower than at high power This is for a safe operation
of the appliance crucial The CO content has to be always lower than 100 ppm (Except during the
ignition phase), otherwise the appliance is not allowed to operate On the two chamber models the
chambers are calibrated separately and can be toggled by turning the lower knob until the desired
chamber and power is displayed Then press the FLEXI button for confirmation
The upper chamber is active when Hi1 or Lo1 is displayed and the lower chamber is active when
Hi2 or Lo2 is displayed Be sure to have the CO2 probe in the correct exhaust pipe
Changing lower power CO2 values
If the measured value differs from the values given in
the table, the CO2 content must be adjusted to match
the values given in the restrictor table The unit was
designed in that way that the CO2 values at high
power are automatically within the range If this is not
the case the installed orifice is wrong or the caloric
heat value of the gas is not normal With the
adjustment screw [1] the CO2 for high power can be
influenced
Unscrew the cap [1] on the gas valve and adjust the
CO2 content using the adjustment screw (white
plastic) behind it during low power operation Refit the
metal cab after calibration is finished
If the low power CO2 value has been changed, the
CO2 values at high power has to be checked again
If the CO2 content at high power is too high or too low
please check that the correct orifice is installed The
CO2 content at high power can be reduced by using
the adjustment screw [2] It has to be turned inwards
to reduce the CO2 at high power
