When working with cleaning agents, nozzle rinsing fluid and spray bottles: Wear
suitable clothing, protective gloves and protective goggles to help protect from
splashes and spills. Failure to do so can result in chemical burns on skin and in eyes.
3. Manual Cleaning of the Oven Chamber
Read, understand, and heed and obey all instructions and safety
information found on cleaning agent labels, Material Safety Data Sheets,
and related documents and sources. Failure to do so can result in death,
injury, and equipment damage.
a. Clean the Combi daily to prevent discoloration and corrosion of the stainless steel.

A. GENERAL INFORMATION
1. Steam generators should be descaled at least once a month, depending on scale buildup. If
you have serious steam generator scale buildup, a water treatment system should be
installed for the steamer. If this is not possible, the frequency of descaling should be
increased.

Testing the outputs
Information:
The electronic controls offer the possibility via the service numbers d04 - d24 to activate various outputs
and various functions. Thereby checking the outputs and detecting any defects.
Safety:
When specific actuators (processes) are often tripped, one after the other, they can be
destroyed!!!
