The maintenance operations described in this chapter have to be fulfilled
periodically to keep the device in good condition and to reduce the
breakdown time to a minimum.
The user can easily execute these operations in accordance with further

to perform the periodical tests and preventive maintenance operations.
Use only mineral-free water as detailed in sec. 3.9 (water quality).

Before carrying out any preventive maintenance operation, ensure that
the electrical cord is disconnected and that there is no pressure in the

dirty it requires cleaning as follows:
Take out the tray holder and trays. Clean the tray holder,
trays and chamber's interior (especially its bottom part)
with a cleaning agent & water. Wipe off the sediments
from the chamber bottom with a sponge. Immediately
after cleaning, rinse the tray holder, trays and chamber's
interior with water to avoid stains on the metal.

the chamber!
