Installation 24
Operating the machine with an incorrect direction of rotation results in damage to the pump,
in which case no vacuum can be created. After connecting the machine to a different three-
phase power supply, the direction of rotation should be checked again. If the direction of
rotation is incorrect, two phases in the plug must be interchanged.
Only a technical expert may perform work on the electrical installation.
