2. Installation

2.1. Positioning of the OvenDo not site the oven close to other appliances (See below) 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. DrainAll 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 mustbe secured to stop movement or damage to the joints. The machine must be sited under a canopy suitable for the removal of the products ofextraction. 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 recommendedin 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 exceed70cm, ifgreater then a non-return valve should be fitted.

6. Characteristics of Operation

6.1. Steam boiler fillingThe 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 energisedIf this value is not reached following a further period of 8 seconds, then the heating is turned off

6.2. Water InjectionThe 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. (vent is opened 1/8 of a turn, and closes after 20 secs. Switch on vent allows water injection

In addition, during automatic cooling mode the temp is pre-set to 70'C, and is adjustable from30 to 250°C, and the water injection is fully automatic until the pre-set temperature is reached.

6.3. Regulation of the heating6.3.1. 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 : If temperature drops 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). 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 reducedto 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 closeIf the temperature is greater than 80°C then the vent closes immediately



6.3.3. Combination Mode

The Convection temp remains unchanged, and steam activates every 4 seconds : 100 ms for 5 % 200 ms for 10 % … 2 secondes for 100 % The steam injection continues when the temperature of the oven is reached. If too much steam is produced, and the temperature of the steam probe is higher than the pre-set oven temperature, then the steam injection is stopped. When using a combination cooking cycle with a cooking temperature of less than 100'C, the steam is stopped at the same time as the convection heaters (Attention : It is recommended in this instance to pre-heat using the steam mode)

6.4. Viewing the temperatures (Oven / Vent)To view the temperature of the program/vent , press the key as shown the values will be indicated in temperature display window (if the START is activated). To remove this display, activate the key again.

6.5. Management of the cooling of the solid state relays and components When the cooking mode is activated, the cooling solenoid valve is activated in order to fill the cooling jacket (during the first filling of the steam boiler).

If is activated, the solenoid passes the value as set in configuration, (normal setting = 5 litres per hour) Config = 1 ltr = Config = 2 ltr = Config = 20 ltr =

A temperature probe is situated to the CPU board, to measure the abient temperature on the board If the board temperature raises to 55'C, the solenoid is activated to 100 % capacity.

If the temperature exceeds 65°C, the heating is stopped, and default 15 is displayed "Overheating of Components" (paragraph 13.1). The component "cooling fan" is operated for the same period as the display is illuminated.

6.6. Digital display panel The control panel increments in 1 second intervals unless the buttons are held permanentlyafter this then the increments are in 10 second steps.

- 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.


3.3. 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 = Config = 2 à EV = Config = 20 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)
