General hints:

Isolate the appliance from mains supply before opening the appliance

When working with chemicals, i.e. aggressive cleaning materials always wear protective clothing, goggles and gloves!

After maintenance / repair the appliance must be checked for electric safety in accordance with your national, state and local requirements!

Whenever working on any gas component like:

Gas valve, gas blower and / or changing connected type of gas a detailedue gas analysis MUST be done using adequate CO and CO2 measuring equipment! This shall ONLY be done by trained technicians! Always check appliance for possible gas leakages!

CM

RATIONAL SC Automatic

During the production of steam, the concentration of minerals inside the steam generator will increase over time. These minerals settle on the heating elements and heat exchanger as well as the interior steam generator walls.

In order to reduce this effect the steam generator will be pumped off and ushed regularly depending on the duration of steam production. This process needs approximately 45 seconds.

After emptying the steam generator it will be lled automatically with fresh water.

There are 4 conditions to start this SC Automatic:

1.Heating time of the steam generator must exceed 60 min.* (SCC Care Control: 120min) and

2.the temperature of the thermocouple inside steam generator (B5) must be below 65°C (149°F) and

3.the temperature of the thermocouple inside interior cabinet (B1) must be below 70°C (158°F) and

4.the unit is switched ON.

* - can be adjusted from 20-120min

In case the unit is used permanently the above mentioned temperature conditions can not be met.

In this case the following 2 conditions apply:

1.The heating time of the steam generator reaches the twice the set duration*, i.e. 120 min. and

2.the unit door is open for longer than 30 seconds

After completion of the SC-Automatic the accumulated steam heating time is re-set to zero.

SC-Automatic does not replace the need for descaling and/or installing water treatment lter

3.After reaching quenching temperature (B2) quenching solenoid Y2 will be activated.

Depending on the frequency of temperature raise of the quenching sensor B2 the duration of the next steam supply is calculated.

4.The amount of steam inside the cabinet is directly depending on the temperature variation of quenching sensor B2.

1.Cleaning program

1)Cool down cabinet below 60°C / 140°F

2)Spray inside cabinet with Rational cleaner

3)Close cabinet door

4)Select „Cool Down

5)Press core temperature key for 10 sec.

6) „CLEn“ will show in cabinet temperature display

7) Press timer key 1x; Cleaning program starts automatically (open cabinet door and rinse interior cabinet after 40 min.) Close door again. Since Software version C1-06-05 a 10 min step hot air will follow to dry the interior cabinet.

2. Empty steam generator

This should be done after each installation to verify free drain connection and prior to disconnection the unit for storage.

1)Open cabinet door

2)Select „Cool Down“

3) Press core temperature key for 10 sec.

4) „CLEn“ will be shown in cabinet temperature display

5) Select „SC“ with temperature dial

6) Close water tap

7) Press timer key 1x and remain on „Cool Down“ position for about 45 sec.

3.Descaling program

1)Open cabinet door

2)Select „Cool Down“

3) Press core temperature key for 10 sec.

4) „CLEn“ will be shown in cabinet temperature display

5) Select „CALC“ with temperature dial

6) Press timer key 1x and follow procedure of the decalci cation instruction. (See user manual CM).

Additional functions CM

4.Changing temperature display from °C to °F

1)Select any mode

2) Press timer and core temperature key simultaneously for 10 sec. until Display changes from °C to °F or vice versa

3) Release both keys

Aborting of descaling program CM:

-Switch unit off and on again

-press core temperature key 1x

-remaining time of 20 minutes will be displayed. During this time the steam generator will be

ushed and the unit will be operated in steam mode for a couple of minutes to eliminate all remaining chemical residues.
