Cleaning The External Casing; Inactivity Period; Maintenance Instructions; Access To The Components For Inspection - eka EKF 412 NALU Original Operating And Instruction Manual

4.6 Cleaning the external casing

The outer steel surfaces must be cleaned with a cloth soaked in warm soapy water or mixed with a little
vinegar, they must be rinsed well and dried with a soft cloth.
Should you wish to use specific products on the market, these must comply with the cleaning requirements
set out in the "Information for the user" paragraph.
It is worth remembering that the counter supporting the appliance, or the floor surrounding the appliance
area, should also be cleaned without using acid corrosive substances (e.g. muriatic acid) since the vapours
released by them might corrode and deteriorate the outer steel shell and cause irreparable damage to the
electrical components inside the appliance.

4.7 Inactivity period

Should the appliance not be used for a long extent of time, it is good practice to disconnect it from the
power supply (act on the safety magnetic circuit breaker located upstream of the appliance) and water
supply. It is recommended to clean it with care internally (cooking chamber) and externally, paying special
attention to removing any salt residues which might lead to corrosion on the steel surfaces.
It is also recommended to protect the appliance with oil-based spray products (e.g. Vaseline oil) which form
an effective protective film when sprayed on the surfaces.
Leave the door of the cooking chamber ajar.
Adequately covering the appliance, finally, allows it to be protected from dust.

5. MAINTENANCE INSTRUCTIONS
