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!

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. (CM - 45 min.)* 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.

S

C M

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. (CM - 90 min.) and

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

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

70°C		raise of the quenching sensor B2 the
		duration of the next steam supply is
(158°F)	B2 - 1
		calculated.
		B2-1: B2 temperature with partial load
	B2 - 2	B2-2: B2 temperature with full load
		4. The amount of steam inside the cabinet is
