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 detailed
ue 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!

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

Additional functions CM
Below are listed the additionaly functions for the user / operator:
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.
8) After end of program, leave cabinet door open over night.
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.
