Bartscher 700 Series Instructions For Installation, Use And Maintenance Manual page 22

When cleaning, abrasive powders of any type, chlorine-based detergents and bleach should all be
avoided. Also avoid pouring cold liquids on appliances while they are hot, or cracks could form which
could cause the appliance to become deformed or broken.
Stainless steel parts should not be exposed to prolonged contact with concentrated acid substances
(e.g. vinegar, condiments, spice mixtures, concentrated kitchen salt...), as they can create chemical
and physical conditions that damage the passivation of the steel. It is therefore advisable to remove
these substances using clean water.
If the appliance is not in use for a long time, it is advisable to turn off the gas tap. Then disconnect
the main electricity supply; wipe all stainless steel surfaces with a cloth soaked in Vaseline oil in
order to give it a protective film; air the rooms now and again.
ATTENTION: Never use substances, detergents and other solutions containing chlorine or its by-
products.
In order to remove any possible scale-marks, do not use products containing salt or sulphuric acid;
suitable products are to be found in the market or, alternatively, a solution diluted in acetic acid can
be used.
While cleaning the appliance, do not use inflammable liquids.
Abnormal functioning
If for any reason, the appliance does not start up or stops working during use, check that the power
supply and the control knobs are set correctly; if all is regular, call customer service.
