9 PROTECTION OF THE APPLIANCE AND USER
9.1 PROTECTION OF THE USER
Safety micro-switches, built into the machine under the rim of the cylinder coverlid
protect the operator against injuries that might be caused by the mixer’s rotation.
Opening the cylinder cover lid will cause the operation of the mixer engine to shut
down.
9.2 ELECTRICAL OVERLOAD PROTECTION
Electrical installations are protected with appropriate FUSES. If the FUSES
terminate the operation of the appliance upon its start-up, the error causing this
action must be found and corrected.
9.3 THERMIC SAFETY DEVICES
The mixer engine and the compressor engine are protected with thermal sensors.
If temperature reaches the maximum allowed value, the protection shuts down the
engine operation. In this case, press the key STOP and allow 15 - 20 minutes for
the engine to cool down. After this time, the appliance is again ready for normal
programming and operating (see the section OPERATING THE APPLIANCE).
9.4 PROTECTION OF THE COOLING SYSTEM
The cooling system is protected with the pressostat at the maximum pressure of
2,5 MPa (25 bar) for the cooling gas R507.
In the case of water shortage, the protection shuts down the operation of the
cooling compressor.
