3.1 Electrical Safety
The power supply should not be tampered with. If it needs to be replaced due to malfunction, it must only be replaced with the same type of power supply by authorised personnel.
|
| An earthed main socket must be used. Be sure that the building installation has dedicated means for over-current and short-circuiting.
|
 Always unplug the machine before performing maintenance and service operations, unless otherwise specified.
|
| Only trained personnel should reach into the control chamber of the machine (accessible from the bottom cover of the machine), containing the electrical and electronic parts.
|
| Do not place any objects filled with liquids, such as vases or cups, on top, around or inside the machine. Use care not to spill liquids into the system. They can cause a failure and/or a fire hazard.
