To allow a distance of at least 100mm from the left of the machine to other equipment and
a minimum distance of 200mm from the right and rear of the machine to allow for air flow.
The oven should be placed on a sound level surface to allow for smooth entry and exit
of the carraige for the 20 grid unit and the rolling supports for the 6/10 series machines.
To prevent the 20 grid oven from moving following installation, the machine should be
secured to the floor using the mounting devices supplied, and secured to the rear wall
using the brackets supplied.
To ensure that the machine is level and that the weight is distributed evenly on all 4 feet.
Important : The machine should be checked again for level, following 1 hour of
operation at 250'C on Convection heat.
2.2. Water Connection
A suitable 3/4" water valve and a double check valve must be supplied as close as possible to the machine.
A suitable softened drinking water supply is recommended.
Water hardness : A Maximum of 5'TH water hardness is acceptable, or a softener is recommended.
Pressure : Minimum flow pressure 2.5 bar; Maximum static pressure 6 bar.
If the water valve is isolated, following 6 minutes of operation a buzzer will sound (Defect 12)
Water Consumptiom (except cleaning) : CSD-0612UC = 18 l/h
CSD-1012UC = 30 l/h
CSD-1022UC = 50 l/h
CSD-2012UC = 50 l/h
CSD-2022UC= 80 l/h
2.3. Drain
All models drain by syphoning the boiler. The drain requires a 11/2" female trapped connection.
The drain pipe should not exceed 1 metre distance from the machine. The drain pipe
diameter must not be reduced.
A drain pipe suitable to carry a water temperature of 85'C must be used. The drain pipe must
be secured to stop movement or damage to the joints.
The machine must be sited under a canopy suitable for the removal of the products of
extraction. Caution : The air temperature at the point of extraction will be the same as
the temperature within the oven.
2.4. Electric Connection
Verify the elctrical supply and suitable fuse ratings as per the instruction(page 4).
To connect the oven to a suitable electric supply using the cable type and size as recommended
in the machine loadings guide. (page 4).
An Earth bonding screw is available under the base of the oven(or adjacent to the mains terminal block),
situated close to the electrical cable gland.
2.5. Cleaning Products
Attention, safety goggles and gloves should be worn whilst handling the detergent products
Place the detergent pipes into the product bottles: White pipe = Detergent Product : Blue pipe = Rinsing Product
The maximum distance between the base of the detergent bottle and the detergent pump should not exceed
70cm, ifgreater then a non-return valve should be fitted.

6. Characteristics of Operation
6.1. Steam boiler filling
The water level in the steam generator is monitored by a differential pressure switch (Pressostat).
The steam generator fills with water when any cooking mode is activated, unless the boiler has not been
drained from the previous occasion.
In test mode the value shown for a full boiler level is 420 points.(Value number only)
A low boiler level is shown as 350 points.(Value number only)
Below this value, then following a 4 second time delay period, the water valve will be energised
If this value is not reached following a further period of 8 seconds, then the heating is turned off
6.2. Water Injection
The water injection system is automatic when changing from Convection mode to Steam mode :
Oven temperature higher than150 °C :
Injection of 1 second of water every 3 seconds (after the vent is opened)
Oven temperature lower than 150° C :
Continuous water injection (after the vent is opened), the water
injection is stopped at 105'C
The symbol
shows cooling is activated.
Manual water injection for cooling is possible :
Higher than 150 °C :
Injection of 1 second of water every 3 seconds
Lower than150 °C :
Injection of water is continuous.

30 to 250°C, and the water injection is fully automatic until the pre-set temperature is reached.
6.3. Regulation of the heating
6.3.1. Convection
Start up :
After turning on the oven, if the cavity temperature is less than 10'C, then the heating is
switched to full power, and increases in increments of 1'C.
When the oven temperature reaches within –10°C of the set temperature, then the heating is
reduced, until the pre-set cooking temperature is reached
If the oven temperature drops below the pre-set value, then the heating is turned on again.
Regulation :
¼ power is activated if the temperature drops below - 0,5°C
½ power is activated if the temperature drops below - 1°C
Full temperature is activated if temperature drops below -2'C
If the temperature rises : Drops to ¼ heating when within 1°C of pre-set value
(¼ power = 1 second activated 3 seconds deactivated).
If temperature
drops
In this mode you can choose the vent position open or closed
.
6.3.2. Steam
If the temperature rises more than 1°C in 2 secondes, then the power level is reduced to ½
power.
When the cooking temperature is lower than 1 degree of the pre-set value, then the heating is reduced
to half power (95'C to100°C).
When opening the door or changing a cooking mode, the oven vent will be opened
If the door is opened:
If the oven temperature is below 55°C, then the vent will be opened, and will close after 55°C is reached.
If the temperature stays between 55°C and 80°C, and the door remains closed, then the vent will close
If the temperature is greater than 80°C then the vent closes immediately

9.1. Input/Output Tests
In case of a fault in operation, the technician can carry out TESTS (SERVICE) in which it is possible to test all the
devices and to visualize these actions in order to guide to the diagnosis of the machne
Certain tests (example: checking the heating of the steam generator ) do not take account of the safety measures of the
functional program.
Attention : When carrying tests, the door should be closed to avoid spillage of detergent products
Caution should be taken when carrying out diagnostic tests
Before carrying out the tests, you must check if the configured parameters are as the customers request.
This menu is accessible at end of SETTINGS (21) menu, by pressing these

Particularities of operation :
3.1.
Injection of water :
- Automatic (cooling) :
If steaming mode is selected and if the temperature in cavity :
- > 150 °C
Injection during 1 sec every 3 sec (spout is open)
- From 150°C to 105°C
Continuous injection (spout is open)
- The spout closed to 105°C
- Manual :
If you press water injection key and if the temperature of the
cavity is :
- > 150 °C :
Injection during 1 sec every 3 sec
- < 150 °C
Continuous water injection
- With the first water injection, the spout is activated during 2 seconds to open
it and avoid overpressures in the oven
The spout is closed again at the end of 20 seconds.

3.2.
Regulation of the heating :
3.2.1.
Convection and combination with water injection :
After the start, if the temperature of the oven is lower than 13°C (convection/combination) or 8°C (steam)
compared to the set point, the full power is activated as far as the set point.
•
•
If the temperature falls :
§
Convection mode:
25 % of power activated to the set point
50 % of power activated to the set point – 0,5°C
100 % of power activated to the set point – 2°C
§
Steam and combination mode :
50 % of power activated to the set point
100 % of power activated to the set point – 1°C
If the temperature rises :
§
convection mode
the heating is stopped to the set point –2°C
§
Steam and combination mode :
The heating is stopped to the set point –2°C
In combination mode to the set point + 3°C when the water injection is activated, the heating is maintained
to 100 %.
If the rise of temperature in oven is more than 1°C for 2 seconds, the heating is stopped.
3.2.2.
Steam with water injection :
The heating is regulated in the same conditions of combination mode with maximum set point 100°C.
The turbine is activated.
The water is injected continuously in the turbine (EV PA0).
When temperature rises, the EV PA2 (humidifier) is activated 1 second over 5 seconds until reaching
97°C.
After the steam mode choice or after door closing, the spout closes :
-
As soon as the temperature rises in the cavity and that this one reached 55°C
Above 80°C in the cavity, the spout closed even if the temperature does not progress.

Management of the static contacts cooling :
As soon as a mode is selected and the door closed, the cooling electromagnetic valve is activated with the
following configuration (settings from 1 to 20).
Config = 1 à EV =

A temperature probe situated on the CPU board controls the ambient temperature. If this temperature
reaches 55°C , the cooling electromagnetic valve is then activated to 100 %. If this temperature is upper
than 65°C, the heating is stopped , the defect 0 over heating components is indicated (paragraphe IV).
The cooling is desactivated with the key OFF.
-
3.4.
Connexion of device to the systems of optimisation of energy :
Connect the control coming from the system on the J4 connectors of CPU (free contact of
potential)
Position the configuration 8 = 1in order to the regulation of the oven takes into account the control
of system of optimization (if this control is to zero, the oven heating is desactivated)
Option : (for connexion to the SICOTRONIC system)
It’s possible to take an information “lit consumer” “terminal A” by connecting this information to the static
contactor L1 convection, on the one hand, and the neutral at exit of the D1 circuit breaker, on the other
hand.
If the device is connected to the system of energy management, and that it is cut by this system, the
defect a appears. If power cut disappears, the heating carry on (the defect stay display until the reset with
OFF key)

3.5.
Speed of turbines (motor FIR 370W / 230V / 50Hz) ::
From the software version 20050323, your must configurate the oven type (at line 6) 6/10/20 levels and
configurate if necessary the low speed (at line 7)
2 = medium speed (750 to 850 rd/mn) convection mode
3 = more quickly
4 = more quickly
The passage from high speed to low speed stops the engine 3 seconds in order to find the low speed
quickly.
With the starting of the engine, high speed is activated 2 seconds except for the 6 levels.

Components fan :
It is activated :
-
When the oven is ON
When the oven is OFF if the temperature of CPU is upper than 60°C

Notifying and handling defects :
Some defects of operation are controlled by the electronics and visualised on the temperature screen (at
space of C or F).
These defects are numbered and if one of them appears during the operation of the oven, the
corresponding number will be displayed and blinked.
