General hints:
Only technicians, who are trained on Rational units, shall execute any service.
Always observe local rules and regulations!
All maintenance work must be done according to the valid laws and regulations applicable.
The unit must be tested to electrical safety (and gas safety if applicable) and manufacturer speci-
cations aer every repair or maintenance work.
Isolate the appliance from mains supply before opening the appliance
When working with chemicals, i.e. aggressive cleaning materials always wear protective cloth-
ing, goggles and gloves!
Please observe the information of the material safety data sheets!
Aer maintenance / repair the appliance must be checked for electrical 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 CO2measuring equipment!
This shall ONLY be done by trained technicians!
Always check appliance for possible gas leakages!
For working on gas units local laws and regulations apply!

Recording of a SCC process with core temp. in
order to run it later on a unit of same size without
core temperature using calibrated (same size)
food.
Powersteam is only visible in selected asian
languages.
Note SCC_XS 60:
Based on the restricted space of the cooking
cabinet some programs are not oered in a SCC_
XS and can not be copied from a bigger unit.

Cockpit
By going throught the pages the user can see the steps done already and the steps ahead.
iLC Messenger
In Intelligent level control additional information like „ time adjusted due to door opening“
can be displayed.
iCC Monitor
All important iLC Messenger informations are listed.
With this the cooking process can be made more transparent
Dialog Cockpit
At the end of the cooking process the possible following tasks are displayed
(e.g. reset core probe)
In DEMO Mode you can run a process identied with „DEMO“ and witness all
messenger and monitor informations as they might pop up during a true process.
Additional also a Cleanjet+Care process can be shown to the customer.
Tapping the clean bar will increase the virtual dirtness and a Cleanjet program can be
started.
