Description
The unit is a volumetric proportion system for liquid substances. The unit produces a constant flow
rate , independent from the incoming water pressure . The flowrate only depends on the frequency
applied to the solenoids. The unit can have a water pressure switch to detect water pressure. The
software of the machine determines the flow rate by adapting the frequency o the solenoids. A
calibration is not needed nor possible. This technology has been engineered and patents applied by
MKN.
Function
The unit consists of a cylinder with a double sided piston. The incoming water pressure drives the
piston to one or the other side, depending which valve is active. The piston drives a specific volume of
water to the outlet. Directly before the water enters the cooking chamber there is a orifice mounted
inside the tube and held with a clamp. Do not operate the unit without that orifice.
Due to the transparent cylinder the piston (seals) can be seen in motion.
The solenoids are supplied with 24V DC.
The pressure switch is set for a pressure of 1 bar (14.5 psi). Operation of the unit is guaranteed up to 6
bar (87 psi)entry pressure. Higher entry pressure requires a pressure reducing valve in front of the unit.
Technical data
Normal Pressure Range: 1.5 – 6 bar (21.8 – 87 psi)
burst pressure: >20 bar (>290 psi)
Maximum flow rate: 28l/h
Volume of cylinder: 3 ml
Electrical supply: 24V DC
Functioning Test
This setting starts a unit functioning test. In the menu “water calibration”, a defined volume flow of
water is emitted. The authorised volume is shown in the main display, the actual flow must be
determined by a measuring jug. To increase the water volume for better a measurement, this procedure
may be repeated several times.
The actual flow may deviate of the authorised flow by +/- 8% (e.g. for an authorised volume of 60ml,
the minimum and maximum volumes are 55ml and 65ml respectively.
The Summary information mask indicates the power supply of the unit by the signs B1 (energized)
And B0 (not energized).
Dual chamber units incorporate two units, which are parallel energized.
Tip:
During the cooking process, the volume flow cannot be determined because it frequently changes
during the process.
At delivery of the combisteamer the water system is empty. This may warrant more time until water
reaches the cooking chamber. During this time, multiple calibration cycles may be initiated.

Functional Troubles
Notice:
This unit allows the replacement of the pressure switch, the filter and the solenoid valves. Any further
dismantling is not allowed (possible water damage, guarantee). After each replacement, a water proof
test is obligatory.
Replacement Of Solenoid Valves
Shut off water supply. Release pressure in the entry lines. Unscrew the solenoid valves.
Pay attention to the three O-rings mounted to the valve body. Take apart the valve body and clean the
valve socket and openings. Carefully clean the valve membrane of sediments. Reassemble the valve
unit (it fits only in easily the correct way). Check the correct location of the three O-rings. The valve
unit must be assembled with the script heading towards the entry opening. Mount the valve body with
a torque of 0.6 +/- 0.1Nm. Assemble the solenoid with the electric connector at the side of the decal P
with a torque of 0.1 – 0.2Nm. Connect the electric supply to the solenoid valve. Mixing up the
electrical valve connections is without consequences. Open the water supply and check the unit water
proof.
Fault Indication “No Water”
Units with a pressure switch display the fault “No Water” in case the pressure switch is still open.
Check entry water pressure. Check electrical connections. The pressure switch opens at 1bar.The
switch point is adjusted by the inner hexagonal nut incorporated in the pressure switch.
Replacement Of Pressure Switch
Shut off water supply. Release pressure in the entry line. Depending of type, disassemble metering
unit. Turn the pressure switch to allow access to the mounting spring. Remove mounting spring with a
small screw driver. Now the pressure switch can be removed. Lightly lubricate the O-ring of the
replacement switch and insert it into the socket. Reconnect the mounting spring by pushing slightly on
the pressure switch. The open side of the mounting spring points toward the entry side of the unit. The
mounting spring must be completely inserted. Reconnect electric power and reassemble the metering
unit if necessary. Open the water supply and test water proof.

Description
Depending on exit temperature the chamber cooling down to 55°C (131°F)
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.
Double pre-cleaning of the chamber by changing the water radically above pump
M16.
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!
Execution of cleaning. The fan runs in a right/left direction. The pump M16
permanently changes the water radically. The running time depends on the chosen
cleaning program.
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 a
right/left direction of rotation as well as in a slow/fast speed.
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!
The rinsing program starts. The fan runs in a right/left direction. The pump M16
permanently changes the water radically. The running time depends on the chosen
cleaning program.
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 a
right/left direction.
The oven starts in steam mode for four minutes to prepare final rinsing. After this the
final rinsing starts.
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.
The device turns off itself now. Cleaning is finished.
During cleaning approx. 3 litres of water are led by 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 cooked room is started with a duration of 12 minutes.This program is carried
out also at a manual cancellation. An entry is written down in the diagnostic and HACCP memory.

For one and two-chamber units:
Pressing the Combi-Plot starts the 100 °C (212°F) calibration. Before setting the offset factor for the
first time, wait at least 30 minutes. When the current probe temperature shows 100 °C (± 1°C) on the
display and the external temperature sensor indicates a value of between 99 °C and 99.5 °C, the unit is
correctly calibrated. If the external device does not reach the temperature range specified, the
temperature offset should be adjusted accordingly by turning the Combi dial.
Caution! After any change to the offset setting, always wait approx. 10 minutes to allow the change to
affect the cooking chamber temperature (temperature on external temperature sensor should remain
stable).
When the actual temperature is at 100 °C ± 1 K, the core temperature sensor is automatically also
calibrated when the calibration is finalised. If the actual temperature is outside of the specified
tolerance, the following message appears: KT sensor not calibrated. For finishing the

When "On", the fan runs during the
time delay to cool the oven chamber
with a block of ice in the bottom
drawer.
For this purpose, place the perforated
container in the closed container, fill
with approximately 4 litres of water
and allow to freeze. Insert the ice
block into the perforated container at
the lowest level. This allows a
temperature of 14°C to be maintained
for up to 6 hours.
Setting minimal: Less water
consumption but higher drain
temperature and more steam from the
exhaust pipe.
Setting maximal: More water
consumption but lower drain
temperature and less steam from the
exhaust pipe.

HW-Fail Temp UREF0 to high
Error description:
The error signalled, that the supply line is disturbed on the circuit board and/or from sensors. A sensor
has a very low resistor or direct chassis ground contact with the frame.
The first possibility is likely if the fault occurs during WaveClean or in steaming mode. Explanation:
The water gets into the probe and builds up an electric connection between the probe itself and the
chassis. Through this connection a voltage potential from the chassis reaches the temperature inputs of
the keyboard pcb and causes the malfunction.
Troubleshooting:
Disconnect the following components one by one to identify the faulty component:
– Pressure switch B10 at the steaming unit
– Core temperature probe B1
– Drain probe B4
– Chamber probe B2
If the fault appears only at the automatic cleaning WaveClean, the drain probe B4 is probably the
cause.
Check power supply of the relay
card (transformer T1 and relay
card plug X3). Also see „Layout
of the relay card“
Change relay pcb.
Change keyboard pcb.. Mount the old
relay pcb again.
